RE: savrstobj and strpasthr both hanging for 2 to 4 minutes

Jim,

Did you ever get to check your LIC LOG entries.

We had a reoccurrence this morning.
The same job containing a SAVRSTOBJ job triggered the issue at 8:31.
Same LIC log entry
08002376 Source/Sink information 0701 0C00 08/03/15 08:31:11 6

At least two users that were already passed through on LPAR B - Pencor06 , were hung.
Once the SAVRSTOBJ completed, they were fine.

The SAVRSTOBJ normally takes 50 seconds.
When the STRPASTHR jobs notice the hanging, the SAVRSTOBJ takes about 4 minutes.

Paul

I will but it will be later since I'm not in the office until Wednesday.

Jim,

Please check if you have this same error in your lic log at the time of the failure.

Jim,

On both your V5R4 and V7R1 systems?

1) Do you have EE configured?
2) Do you use SAVRST*** cmds?
3) Do you use STRPASTHR?

I also only see this once every several months.
We SAVRST*** both directions, but the issue only occurs A to B.
STRPASTHR is only A to B.

Paul

On that system about every 90 days or so.

On my V7Rx systems I've not had a problem.

I like the thought of the AJS to set the comm trace.

Jim,

How often do you see this?
I was not successful in gathering comm traces, they need to be running prior to the error.
I'm considering setting up AJS scheduled jobs to start and end the comm traces, during the same time we run the SAVRST*** jobs.

Paul,

I've seen this behavior but it's on a V5R4 system so I'm not sure it's relevant. When that happens we force the vary off of the enterprise controller and the controller named for the target. Same thing on the target side. Then restart the target then the local system. There must be a TCP timeout somewhere because we have to leave the controllers varied off for at least 3 minutes.

My own guess, and its' purely a guess is the HPR transport code has some
sort of problem. IBM's gonna want a comm trace to diagnose it.

I had a repeat of an old issue, savrstobj and strpasthr both hanging for 2 to 4 minutes.
Had multiple previous posts on similar issue.

We use both SAVRSTOBJ and SAVRSTLIB to move objects between LPARS.
We also use STRPASTHR to connect from LPAR to LPAR.

Previously, Enterprise Extender controllers needed resets, not this time.

This time, no error messages, no resets, just a hang.

Could this be a lock, seize, other issue?
Is there any reason why multiple processes (Strpasthr/Savrrstob) cannot be started/initiated concurrently?

Any thoughts?

Thank You
