Solaris 10, limit & SAP J2EE 7.11

[ganimede_dignan]

Hi,

in a Solaris 10 X64 box I've got and issue. It is a SAP J2EE 7.11 CE SAP MII 12.1 usage. Into /usr/sap/MIP/JXX/work/dev_icm log file there is a message:

[Thr 01] Fri Jul  5 09:49:44 2013

[Thr 01] Parameter system/type has value: "J2EE"

[Thr 01] *** WARNING => The maximum number of sockets supported on this host is 250.

This is less than the number of sockets configured in parameter icm/max_sockets (2048) [icxxman_mt.c 3335]

[Thr 01] started security log to file ./dev_icm_sec

I've already read SAP note number 737625... I try to apply it but the message is still exists. Have you got any advice?

The limit output from <sid>adm is:

cputime	unlimited
filesize	unlimited
datasize	unlimited
stacksize	10240 kbytes
coredumpsize	unlimited
descriptors	4096
memorysize	unlimited

The limit output from ora<sid> is:

cputime	unlimited
filesize	unlimited
datasize	unlimited
stacksize	10240 kbytes
coredumpsize	unlimited
descriptors	4096
memorysize	unlimited

The limit output from root is:

cputime	unlimited
filesize	unlimited
datasize	unlimited
stacksize	10240 kbytes
coredumpsize	unlimited
descriptors	256
memorysize	unlimited

Thank you.

Hi,

it should be OK, see below.

Hi Ganimede,

Could you try setting following parameters in the file /etc/system:

     For mpi/max_pipes of 4,000: 

        set semsys:seminfo_semmni=500

         set semsys:seminfo_semmns=50000

    For mpi/max_pipes of 20,500:

        set semsys:seminfo_semmni=1000

        set semsys:seminfo_semmns=50000

Values for mpi/max_pipes should be calculated based on SAP note 737625.

Additionally try to change the descriptors settings for root user ( currently its 256) to 2048 and check the results.

Hope this helps.

Regards,

Deepak Kori

I've just find that into .sapenv.csh there is:

switch (`uname`)

    case Sun*:

        limit descriptors 4096

        unsetenv LD_LIBRARY_PATH_64

        breaksw

    case OS\/390:

        alias hostname 'hostname -s'

        breaksw

    default:

endsw

so, each time descriptors is modified by a login script

Hello Ganimede,

sapenv.csh is taken only if no .sapenv_<hostname>.csh exists.

It looks like instead of the limit of <sid>adm the limit of root would be used.

This is a known issue, see SAP note 1437105 and 1827960.

Steps in brief:

- check the limit known by sapstartsrv

      sapcontrol -nr <instance nr.> -function OSExecute "/bin/ksh ulimit -a" 0 0

- download the newest sapinit

- add

      limit.descriptors=4096

  in /usr/sap/sapservices

- restart sapstartsrv

- check the limit known by sapstartsrv

      sapcontrol -nr <instance nr.> -function OSExecute "/bin/ksh ulimit -a" 0 0

Best regards

Hi Ganimede,

Solaris 10 doesn't use /etc/system but uses projects.

Check 

Note 724713 - parameter settings for Solaris 10

and make sure the parameter process.max-file-descriptor is set in the project and that the user <sid>adm is assigned to that project in /etc/user_attr

Hope this helps.
