SAPOSCOL running at OS level, but not reflected in GUI level

[Former Member]

Hi All,

On our ECC 6.0 system, the saposcol is running at OS Level. However when the same is checked through GUI level using ST06, it says SAPOSCOL not running.

We have even tried restarting the system by clearing all the shared memory but no luck.

We use db2 9.7 database and AIX 7.1. we have a single LPAR and multiple WPARS resting on this single LPAR. We have noticed that the other systems resting on all other WPARS, SAPOSCOL is running  at OS and is reflected at GUI level.

Could you please advise.

Output from OS level:

./saposcol -s

Hello Soumya,

Pleas make sure : the SAPOSCOL is the latest one

The operating system collector SAPOsCol is a stand-alone program that runs in the operating system background. It runs independently of

SAPinstances exactly once per host.Saposcol is not Unicode-dependent, so it makes no difference to download it from Unicode or Non-unicode

directory on Service Market Place.The highest available saposcol version can always be used backwards.

SAPOSCOL should always be started with root permissions, to be able to collect all the OS statistics (notes #19227 and #726094).

#548699 - FAQ: OS collector SAPOSCOL

#710975 - FAQ: which saposcol should be used on AIX
#1756498 - saposcol on AIX: multiple saposcol processes

I would like to suggest to check the SAPOSCOL logfile : dev_coll if it is free from errors:

Dear Soumya,

Please check default background jobs are running or not.

SAP_COLLECTOR_FOR_PERFORMANCE.

And also check time zone and correct it for OS and SAP level...

Thanks & Regards,

Hi,

SAPHOSTAGENT is installed and we are on the latest patch level.

However now SAPOSCOL is being reflected at GUI level and also now the snapshot details are available in ST06. But if i try checking the history details, it displays nothing except for the blank fields.

The related jobs such as SAP_PERFMONITOR and all are running on regular basis.

Any inputs on why the history data not being available ?

Thanks,

Soumya

Hi Soumya,

     Try these..

1. First stop the Saposcol from Os level

2. Kill the <pid> of the oscol if it is runnning

3. go to the path "/usr/sap/tmp"

4. rename the file "coll.put" file to "coll.old" (You can do when the system is online)

5. Now start the Saposcol

Hope it will resolve your issue.. Give me points if it helps you

Hello

Stop the SAPOSCOL from the OS level and start it from Tx ST06

Install SAPHOSTAGENT.

Try to check for errors in txn SM21.

[Former Member]

I have checked but found nothing relevant in SAP logs.

[Sriram2009]

Hi Soumya

Just do the full restart and than check in SAPGUI?

As another quick test do the following: in SM69 define external command ipcs and start it with -am parameter. Can you see saposcol shared segment in output? Also try to check dev_w* log file for additional info. If possible please attach screenshot with error and explain a bit more landscape that has been deployed on this LPAR.

Hi

Is the kernel version 7.20 ?

Kindly refer the SAP Note

1131691 - CPU utilization metrics of IBM System p

895816 - ST06 statistics are misleading in SPLPARS on AIX

994025 - Virtualized OS environments in the operating system monitor

Hi Raman,

Could you please explain how exactly to add the external command?
