How to Start Serv0 Process in ABAP+JAVA Stack without restaring

Former Member

Hi

We have our SAP Systems in ABAPJAVA Stacks. Some times the server0 process does not show up at the AS/400 screen screen even though all other processes showup. Is there a way we can start Serv0 Process in ABAPJAVA Stack without restaring the entire system.

I tried the following. Loged in to the ABAP System and from transaction : SMICM

Menu Option

Administrator --> J2EE Instance(Local) --> Restart --> Yes

Administrator --> J2EE Cluster (Global) --> Restart --> Yes

but still the service did not show up.

Any Help in this reagrd would be greatly appreciated.

The following services are shown in the green screen at the AS/400 OS Level

Subsystem/Job User Type CPU % Function Status

R3_20 QSYS SBS .0 DEQW

DISP_WORK SMP20 BCI .0 PGM-disp+work SELW

DISPATCHER SMP20 BCI .0 PGM-jlaunch THDW

GWRD SMP20 BCI .0 PGM-gwrd SELW

ICMAN SMP20 BCI .0 PGM-icman SELW

Hi,

I usually use the 'send soft shutdown' with restart (in SMICM). Then I monitor in WRKACTJOB if everything goes down and then restarts. If this doesn't work try the 'send soft shutdown' without restart and then when everything is down, do the 'soft shutdown' with restart.

If this still doesn't help, use 'hard shutdown' without restart and the then restart once everything is down. It can take some time if it is really hung up until all JAVA processes are gone.

This doesn't sound like the best method, but it works and we don't have to stop the ABAP instance.

Hi Kishore,

first of all, there's probably a problem with server0. Generally it should come up automatically. And one can see JCONTROL and DISPATCHER, so there must be some problem with SERVER0. This could be a timeout for instance. One has to check dev_server0 and std_server0 files.

However, you can of course start/stop the Java part independently from ABAP using the transaction SMICM. That's the official way. You should be able to use "soft shutdown with restart" if you just want to restart the Java stack. If you have doubts that this process went fine, trigger a "soft shutdown without restart" and wait until all java processes are gone (JCONTROL, DISPATCHER, SERVER<number>'s and SDM). Then use "Restart Yes" to trigger a new start.

But, as I said, there's probably some issue in server0...

Best regards,

Christoph
