No all the file systems were JFS2/SAN mounted.

Thank you all. The issue has been resolved successfully. Followed the below steps as suggested by IBM support. What a relief ! (1) Enable release-behind(RBRW) on the filesystems - datasets and scratch and re-mount the file systems across AIX server.This will let the system return the memory to the f...

We had raised a PMR earlier which is still open. It was suggested by PMR engineers(after adding multiple debug variables at project level and then running the jobs and collecting the log files and sharing with IBM support) that disk contention is causing slowness in 11.5.0.2, it was observed through...

Not yet. Disk re-configuration done. Separate volume groups created for all major file systems, with each volume group(VG) having non shareable SSD disks allocated. All file systems mounted over SAN. eg VG1 : /opt/IBM/InfomationServer (disk 1, disk 2) VG2 : /ETL/Datasets (disk 3, disk 4, disk 5, dis...

Tourist count at the time of slowness is ~15 and total number of jobs running in parallel at that time is around 15 to 20 with 25% of the jobs being multiple instance jobs.

If we leave the system as such at the time of slowness, the jobs used to run till completion, the only issue is that if any job which is supposed to finish in eg 30 minutes(baseline 9.1.2 run of same job against same data volume), it takes 10X more time in 11.5 Yes, at the time of slowness - multipl...

Thank you all for your valuable inputs. We tried settings below variables at project level, as advised by PMR support engineers. APT_DEBUG_CLEANUP=1 APT_NO_JOBMON=1 APT_SHOW_COMPONENT_CALLS=1 APT_PM_PLAYER_TIMING=1 APT_NO_PM_SIGNAL_HANDLERS=1 CORE_NAMING=true APT_DUMP_SCORE=true APT_PM_SHOW_PIDS=tru...

Ok PaulVL. So do you think that its a product short coming? Kindly share some details if you have also observed similar issue in the upgraded version of InfoSphere Information Server 11.5.0.2

We are literally struggling. Appreciate your inputs.

Thank you so much !

Problem still NOT resolved. I will make sure to update this post once we get a permanent solution. Sev 1 PMR in place. Following up closely with IBM Customer Support. Exchanged lot of log files in last 2 weeks with them. They suggested to do disk re-configuration on the AIX server where DS engine is...

IBM customer support suggested below changes in uvconfig. Change MFILES from default 200 to 500. Change T30FILES from default 512 to 1000 Change GLTABSZ from default 75 to 300 We made above three changes BUT issue still not resolved. Then we reverted back T30FILES from 1000 to 512 and GLTABSZ from 3...

Thanks for your inputs guys. This is what we have in uvconfig file. RLTABSZ 300 GLTABSZ 75 MAXRLOCK 299 Yes, we are seeing large number of defunct processes owned by dsadm user, defunct processes noticed at job run time. The RT LOG/STATUS files' size is normal. Largest file with 0.97 MB so far. We s...

Log retention policy is set as auto purge : Last 10 runs. We have two message handlers defined at project level for 2 projects(one for each project). #1 and #2 below. We have two more message handlers defined and used in couple of jobs(#3 and #4 below). (1) IIS-DSEE-TFXR-00017 3 Warning converted to...

Hi Experts, We recently migrated from IIS 9.1.2 to 11.5.0.2 version across AIX 7.1 platform, non CDB oracle 12c metadata repository. We have 4 tier architecture(1 for each - services, engine, metadata repository and 4th one - the client tier). Services tier, engine tier and metadata repository tier-...
