Discussion:
AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC 2056 error code. The fs space is ok so I need to increase the Ulimit -f to an acceptable size. It is currently set to 2097151. The largest message I have seen so far is 3888786 bytes. We don't get the error for every message that exceeds the 2097151 file size, so there must be some translation, or maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=swg21194240 which is pasted below.

My question is, how can "The user file limit of 4194302 will allow a 2 Gigabyte queue file. "?

4194302 is 4 megabytes...


WMQ error code 2056 Queue space not available on an MQPUT




Technote (troubleshooting)



Problem(Abstract)

You put a message to a Websphere MQ (WMQ) queue, and the following is returned to your application:

2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE

Cause


The user file limit restricted the size of the queue file.

Resolving the problem


Configure your file system for larger queue files

Set your hard file limit, if necessary, "ulimit -Hf 4194302".
Set your user file limit, "ulimit -f 4194302".


The user file limit of 4194302 will allow a 2 Gigabyte queue file.



Additional information

Command "df" reports a block size of 512.

Command "ulimit -f" reports a size < 4194302

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of the ulimit setting. One way to enable files larger than the 2 GB limit is to create the file system with the Large File Enabled option. This option can be found through the Add a Journaled File System option of the smit menu. Refer to AIX documentation for additional information and file system options.

We set ours to: unlimited

Hi Linda,

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x 512 = 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

You're welcome. Incidentally, 4,194,304 x 512 = 2,147,483,648 (2 gigabytes). I wonder if they meant to say 4,194,304 in their tech note, but maybe they had a reason for going slightly under 2 gig.

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of the ulimit setting. One way to enable files larger than the 2 GB limit is to create the file system with the Large File Enabled option. This option can be found through the Add a Journaled File System option of the smit menu. Refer to AIX documentation for additional information and file system options.

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC 2056 error code. The fs space is ok so I need to increase the Ulimit -f to an acceptable size. It is currently set to 2097151. The largest message I have seen so far is 3888786 bytes. We don't get the error for every message that exceeds the 2097151 file size, so there must be some translation, or maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=swg21194240 which is pasted below.

My question is, how can "The user file limit of 4194302 will allow a 2 Gigabyte queue file. "?

4194302 is 4 megabytes...

Hi Linda,

To answer your question:

"My question is, how can "The user file limit of 4194302 will allow a 2 Gigabyte queue file. "?

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x 512 = 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of the ulimit setting. One way to enable files larger than the 2 GB limit is to create the file system with the Large File Enabled option. This option can be found through the Add a Journaled File System option of the smit menu. Refer to AIX documentation for additional information and file system options.

Hi Linda,

Do you have more details in how the file size resource limit change for mqm was implemented?

Did a Unix systems administrator perform the change? If so, they could better speak to the effect of what was done, but more than likely the queue manager would have to be restarted for new processes to pick up that file size resource limit change. At least that is what I would anticipate.

Or did you update a queue manager start up script to set the ulimit before starting the queue manager? In this case, I would assume a restart of the queue manager would be required, as well.

I am not aware of a way to dynamically inject a resource limit change into a running process, but maybe that does exist on Unix systems like AIX.

You shouldn't need to delete/define any files. You are changing a file size resource limit, and resource limits are specific to a process, not to a file. Any new mqm processes should pick up the increased file size resource limit and then be able to create larger files.

Thanks,
Tim

So now that I have Ulimit -f set to 4194304 on my servers for mqm, I believ=
e I only have to delete/define the queues that need to take advantage of th=
e larger size. Would there be a reason to recycle the queue manager? Mayb=

They use 4194302 and not 4194304. Not sure why.

You're welcome. Incidentally, 4,194,304 x 512 =3D 2,147,483,648 (2 gigabyt=

they had a reason for going slightly under 2 gig.

Hi Linda,

To answer your question:

"My question is, how can "The user file limit of 4194302 will allow a 2 Gi=
gabyte queue file. "?

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x 51=
2 =3D 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of t=
he ulimit setting. One way to enable files larger than the 2 GB limit is to=
create the file system with the Large File Enabled option. This option can=
be found through the Add a Journaled File System option of the smit menu. =
Refer to AIX documentation for additional information and file system optio=

We set ours to: unlimited

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC 20=
56 error code. The fs space is ok so I need to increase the Ulimit -f to a=
n acceptable size. It is currently set to 2097151. The largest message I =
have seen so far is 3888786 bytes. We don't get the error for every messag=
e that exceeds the 2097151 file size, so there must be some translation, or=
maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=3Dswg21194240 which is pasted=
below.

My question is, how can "The user file limit of 4194302 will allow a 2 Giga=
byte queue file. "?

4194302 is 4 megabytes...


WMQ error code 2056 Queue space not available on an MQPUT




Technote (troubleshooting)



Problem(Abstract)

You put a message to a Websphere MQ (WMQ) queue, and the following is retur=
ned to your application:

2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE

Cause


The user file limit restricted the size of the queue file.

Resolving the problem


Configure your file system for larger queue files

Set your hard file limit, if necessary, "ulimit -Hf 4194302".
Set your user file limit, "ulimit -f 4194302".


The user file limit of 4194302 will allow a 2 Gigabyte queue file.



Additional information

Command "df" reports a block size of 512.

Command "ulimit -f" reports a size < 4194302

The UNIX team updated the AIX /etc/security/limits for mqm. I imagine they forgot to execute the chuser command to implement the change because on one server, the setting is OK, but when I issue the Ulimit -f command, it still shows the old value.

I am pretty sure I need to delete/define any existing queues that I want to have pick up the higher limit. I forget where I read this...

Hi Linda,

Do you have more details in how the file size resource limit change for mqm was implemented?

Did a Unix systems administrator perform the change? If so, they could better speak to the effect of what was done, but more than likely the queue manager would have to be restarted for new processes to pick up that file size resource limit change. At least that is what I would anticipate.

Or did you update a queue manager start up script to set the ulimit before starting the queue manager? In this case, I would assume a restart of the queue manager would be required, as well.

I am not aware of a way to dynamically inject a resource limit change into a running process, but maybe that does exist on Unix systems like AIX.

You shouldn't need to delete/define any files. You are changing a file size resource limit, and resource limits are specific to a process, not to a file. Any new mqm processes should pick up the increased file size resource limit and then be able to create larger files.

Thanks,
Tim

So now that I have Ulimit -f set to 4194304 on my servers for mqm, I believ=

They use 4194302 and not 4194304. Not sure why.

You're welcome. Incidentally, 4,194,304 x 512 =3D 2,147,483,648 (2 gigabyt=

Hi Linda,

To answer your question:

"My question is, how can "The user file limit of 4194302 will allow a 2 Gi=
gabyte queue file. "?

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x 51=
2 =3D 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of t=
he ulimit setting. One way to enable files larger than the 2 GB limit is to=
create the file system with the Large File Enabled option. This option can=
be found through the Add a Journaled File System option of the smit menu. =

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC 20=
56 error code. The fs space is ok so I need to increase the Ulimit -f to a=
n acceptable size. It is currently set to 2097151. The largest message I =
have seen so far is 3888786 bytes. We don't get the error for every messag=
e that exceeds the 2097151 file size, so there must be some translation, or=
maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=3Dswg21194240 which is pasted=
below.

My question is, how can "The user file limit of 4194302 will allow a 2 Giga=
byte queue file. "?

4194302 is 4 megabytes...


WMQ error code 2056 Queue space not available on an MQPUT




Technote (troubleshooting)



Problem(Abstract)

You put a message to a Websphere MQ (WMQ) queue, and the following is retur=
ned to your application:

2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE

Cause


The user file limit restricted the size of the queue file.

Resolving the problem


Configure your file system for larger queue files

Set your hard file limit, if necessary, "ulimit -Hf 4194302".
Set your user file limit, "ulimit -f 4194302".


The user file limit of 4194302 will allow a 2 Gigabyte queue file.



Additional information

Command "df" reports a block size of 512.

Command "ulimit -f" reports a size < 4194302

To the best of my - albeit limited and outdated - knowledge, ulimit
changes do not affect existing files. So you would need to delete and
recreate the queues because you need to delete and recreate the q storage
files.

It's worth a review with your AIX support team.

Thank you,

Jeff Lowrey

The UNIX team updated the AIX /etc/security/limits for mqm. I imagine
they forgot to execute the chuser command to implement the change because
on one server, the setting is OK, but when I issue the Ulimit -f command,
it still shows the old value.

I am pretty sure I need to delete/define any existing queues that I want
to have pick up the higher limit. I forget where I read this...

Hi Linda,

Do you have more details in how the file size resource limit change for
mqm was implemented?

Did a Unix systems administrator perform the change? If so, they could
better speak to the effect of what was done, but more than likely the
queue manager would have to be restarted for new processes to pick up that
file size resource limit change. At least that is what I would
anticipate.

Or did you update a queue manager start up script to set the ulimit before
starting the queue manager? In this case, I would assume a restart of the
queue manager would be required, as well.

I am not aware of a way to dynamically inject a resource limit change into
a running process, but maybe that does exist on Unix systems like AIX.

You shouldn't need to delete/define any files. You are changing a file
size resource limit, and resource limits are specific to a process, not to
a file. Any new mqm processes should pick up the increased file size
resource limit and then be able to create larger files.

Thanks,
Tim

They use 4194302 and not 4194304. Not sure why.

Hi Linda,

To answer your question:

"My question is, how can "The user file limit of 4194302 will allow a 2
Gi=
gabyte queue file. "?

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x
51=
2 =3D 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of
t=

to=
create the file system with the Large File Enabled option. This option

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC
20=
56 error code. The fs space is ok so I need to increase the Ulimit -f to
a=
n acceptable size. It is currently set to 2097151. The largest message I
=
have seen so far is 3888786 bytes. We don't get the error for every
messag=
e that exceeds the 2097151 file size, so there must be some translation,
or=
maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=3Dswg21194240 which is
pasted=
below.

My question is, how can "The user file limit of 4194302 will allow a 2
Giga=
byte queue file. "?

4194302 is 4 megabytes...


WMQ error code 2056 Queue space not available on an MQPUT




Technote (troubleshooting)



Problem(Abstract)

You put a message to a Websphere MQ (WMQ) queue, and the following is
retur=
ned to your application:

2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE

Cause


The user file limit restricted the size of the queue file.

Resolving the problem


Configure your file system for larger queue files

Set your hard file limit, if necessary, "ulimit -Hf 4194302".
Set your user file limit, "ulimit -f 4194302".


The user file limit of 4194302 will allow a 2 Gigabyte queue file.



Additional information

Command "df" reports a block size of 512.

Command "ulimit -f" reports a size < 4194302

It would definitely be best for Linda to check with the AIX support team to get a definitive answer.

Maybe there is something MQ is storing internally that needs to be reset with a queue deletion/recreation, but it does not make sense to me why this would be needed. A user resource limit like max file size is specific to a process. When the process gets created, this value gets stored in a data structure and then the operating system will check this value when the process tries to do system calls (i.e write) to increase the file size. If the operating system detects that the system call would bring the file size over the max limit, it fails the system call and returns an error code to the process. So it does not make sense to me why a file would need to be deleted/created based on a user resource limit change like max file size. But maybe I am missing something. It wouldn't be the first time. :)

Thanks,
Tim

To the best of my - albeit limited and outdated - knowledge, ulimit changes do not affect existing files. So you would need to delete and recreate the queues because you need to delete and recreate the q storage files.

It's worth a review with your AIX support team.

Thank you,

________________________________



The UNIX team updated the AIX /etc/security/limits for mqm. I imagine they forgot to execute the chuser command to implement the change because on one server, the setting is OK, but when I issue the Ulimit -f command, it still shows the old value.

I am pretty sure I need to delete/define any existing queues that I want to have pick up the higher limit. I forget where I read this...

Subject: Re: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi Linda,

Do you have more details in how the file size resource limit change for mqm was implemented?

Did a Unix systems administrator perform the change? If so, they could better speak to the effect of what was done, but more than likely the queue manager would have to be restarted for new processes to pick up that file size resource limit change. At least that is what I would anticipate.

Or did you update a queue manager start up script to set the ulimit before starting the queue manager? In this case, I would assume a restart of the queue manager would be required, as well.

I am not aware of a way to dynamically inject a resource limit change into a running process, but maybe that does exist on Unix systems like AIX.

You shouldn't need to delete/define any files. You are changing a file size resource limit, and resource limits are specific to a process, not to a file. Any new mqm processes should pick up the increased file size resource limit and then be able to create larger files.

Thanks,
Tim

They use 4194302 and not 4194304. Not sure why.

Hi Linda,

To answer your question:

"My question is, how can "The user file limit of 4194302 will allow a 2 Gi=
gabyte queue file. "?

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x 51=
2 =3D 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of t=
he ulimit setting. One way to enable files larger than the 2 GB limit is to=
create the file system with the Large File Enabled option. This option can=
be found through the Add a Journaled File System option of the smit menu. =
Refer to AIX documentation for additional information and file system optio=
ns.

We set ours to: unlimited

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC 20=
56 error code. The fs space is ok so I need to increase the Ulimit -f to a=
n acceptable size. It is currently set to 2097151. The largest message I =
have seen so far is 3888786 bytes. We don't get the error for every messag=
e that exceeds the 2097151 file size, so there must be some translation, or=
maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=3Dswg21194240 which is pasted=
below.

My question is, how can "The user file limit of 4194302 will allow a 2 Giga=
byte queue file. "?

4194302 is 4 megabytes...


WMQ error code 2056 Queue space not available on an MQPUT




Technote (troubleshooting)



Problem(Abstract)

You put a message to a Websphere MQ (WMQ) queue, and the following is retur=
ned to your application:

2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE

Cause


The user file limit restricted the size of the queue file.

Resolving the problem


Configure your file system for larger queue files

Set your hard file limit, if necessary, "ulimit -Hf 4194302".
Set your user file limit, "ulimit -f 4194302".


The user file limit of 4194302 will allow a 2 Gigabyte queue file.



Additional information

Command "df" reports a block size of 512.

Command "ulimit -f" reports a size < 4194302

I checked with my UNIX admin, he says it will happen dynamically.
We shall see!!

Subject: Re: AIX ulimits filesize of 4194304 - 2 gig queue size?

It would definitely be best for Linda to check with the AIX support team to get a definitive answer.

Maybe there is something MQ is storing internally that needs to be reset with a queue deletion/recreation, but it does not make sense to me why this would be needed. A user resource limit like max file size is specific to a process. When the process gets created, this value gets stored in a data structure and then the operating system will check this value when the process tries to do system calls (i.e write) to increase the file size. If the operating system detects that the system call would bring the file size over the max limit, it fails the system call and returns an error code to the process. So it does not make sense to me why a file would need to be deleted/created based on a user resource limit change like max file size. But maybe I am missing something. It wouldn't be the first time. :)

Thanks,
Tim

To the best of my - albeit limited and outdated - knowledge, ulimit changes do not affect existing files. So you would need to delete and recreate the queues because you need to delete and recreate the q storage files.

It's worth a review with your AIX support team.

Thank you,

________________________________



The UNIX team updated the AIX /etc/security/limits for mqm. I imagine they forgot to execute the chuser command to implement the change because on one server, the setting is OK, but when I issue the Ulimit -f command, it still shows the old value.

I am pretty sure I need to delete/define any existing queues that I want to have pick up the higher limit. I forget where I read this...

Subject: Re: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi Linda,

Do you have more details in how the file size resource limit change for mqm was implemented?

Did a Unix systems administrator perform the change? If so, they could better speak to the effect of what was done, but more than likely the queue manager would have to be restarted for new processes to pick up that file size resource limit change. At least that is what I would anticipate.

Or did you update a queue manager start up script to set the ulimit before starting the queue manager? In this case, I would assume a restart of the queue manager would be required, as well.

I am not aware of a way to dynamically inject a resource limit change into a running process, but maybe that does exist on Unix systems like AIX.

You shouldn't need to delete/define any files. You are changing a file size resource limit, and resource limits are specific to a process, not to a file. Any new mqm processes should pick up the increased file size resource limit and then be able to create larger files.

Thanks,
Tim

So now that I have Ulimit -f set to 4194304 on my servers for mqm, I believ=
e I only have to delete/define the queues that need to take advantage of th=
e larger size. Would there be a reason to recycle the queue manager? Mayb=
e for the log files?

They use 4194302 and not 4194304. Not sure why.

You're welcome. Incidentally, 4,194,304 x 512 =3D 2,147,483,648 (2 gigabyt=
es). I wonder if they meant to say 4,194,304 in their tech note, but maybe=
they had a reason for going slightly under 2 gig.

Hi Linda,

To answer your question:

"My question is, how can "The user file limit of 4194302 will allow a 2 Gi=
gabyte queue file. "?

4194302 is 4 megabytes..."

It looks like in AIX that ulimit -f is in 512 byte blocks. So 4194302 x 51=
2 =3D 2,147,482,624 bytes (which is very close to 2 gigabytes).

Thanks,
Tim

Create file systems with large file support

The standard file system on AIX has a 2 GB file size limit, regardless of t=
he ulimit setting. One way to enable files larger than the 2 GB limit is to=
create the file system with the Large File Enabled option. This option can=
be found through the Add a Journaled File System option of the smit menu. =
Refer to AIX documentation for additional information and file system optio=
ns.

We set ours to: unlimited

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?

Hi, My applications are sending some large messages and getting the MQRC 20=
56 error code. The fs space is ok so I need to increase the Ulimit -f to a=
n acceptable size. It is currently set to 2097151. The largest message I =
have seen so far is 3888786 bytes. We don't get the error for every messag=
e that exceeds the 2097151 file size, so there must be some translation, or=
maybe 2097151 is in blocks?

Can someone help clear this up for me?
Thanks!

I read this technote:
http://www-01.ibm.com/support/docview.wss?uid=3Dswg21194240 which is pasted=
below.

My question is, how can "The user file limit of 4194302 will allow a 2 Giga=
byte queue file. "?

4194302 is 4 megabytes...


WMQ error code 2056 Queue space not available on an MQPUT




Technote (troubleshooting)



Problem(Abstract)

You put a message to a Websphere MQ (WMQ) queue, and the following is retur=
ned to your application:

2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE

Cause


The user file limit restricted the size of the queue file.

Resolving the problem


Configure your file system for larger queue files

Set your hard file limit, if necessary, "ulimit -Hf 4194302".
Set your user file limit, "ulimit -f 4194302".


The user file limit of 4194302 will allow a 2 Gigabyte queue file.



Additional information

Command "df" reports a block size of 512.

Command "ulimit -f" reports a size < 4194302

I dug up some old notes I used in preparing a qmgr for AIX. In addition to
Lawrence's recommendation for large file system support, you have to enable
it specifically for /var/mqm.



Other things I checked for/had done:



. AIX

* File descriptors

. Increase nofiles attribute limit for userid mqm to 10,000 in
/etc/security/limits

* System Resource Limits for data and stack segments

. unlimit -d unlimited

. unlimit -s unlimited

* Large files

. Enable /var/mqm to use large files

Subject: AIX ulimits filesize of 4194304 - 2 gig queue size?



Hi, My applications are sending some large messages and getting the MQRC
2056 error code. The fs space is ok so I need to increase the Ulimit -f to
an acceptable size. It is currently set to 2097151. The largest message I
have seen so far is 3888786 bytes. We don't get the error for every message
that exceeds the 2097151 file size, so there must be some translation, or
maybe 2097151 is in blocks?



Can someone help clear this up for me?

Thanks!



I read this technote:

http://www-01.ibm.com/support/docview.wss?uid=swg21194240 which is pasted
below.



My question is, how can "The user file limit of 4194302 will allow a 2
Gigabyte queue file. "?



4194302 is 4 megabytes.





WMQ error code 2056 Queue space not available on an MQPUT









Technote (troubleshooting)







Problem(Abstract)



You put a message to a Websphere MQ (WMQ) queue, and the following is
returned to your application:



2056 0x00000808 MQRC_Q_SPACE_NOT_AVAILABLE



Cause





The user file limit restricted the size of the queue file.



Resolving the problem





Configure your file system for larger queue files



Set your hard file limit, if necessary, "ulimit -Hf 4194302".

Set your user file limit, "ulimit -f 4194302".





The user file limit of 4194302 will allow a 2 Gigabyte queue file.







Additional information



Command "df" reports a block size of 512.



Command "ulimit -f" reports a size < 4194302

Thanks for the extra info. I already had the ulimits set according to their recommendations. But this is the first time I have seen a lot of large files in a queue at the same time, enough to max out the Ulimit setting anyway.
