PI Java Satck down

[Former Member]

Hi gurus,

In My PI server all of a sudden Java stack went down. After rebouncing the server everything started working fine.

But i am unable to understand why the Java stack went down all of a sudden. how do i analyse what was the issue and how can i avoid it in the future.

Thanks a lot in advane.

Priya,

Please check logs (work directory) and trace is work folder.

Like, dev_server0, dev_disp, std_server0.out etc. and also default trace.

You will come to know more details.

Priya,

As you have restarted system, you need to check dev_disp.old, dev_server0.old etc files now because new files are generated after system restart. Also please check default traces. It will give you error details with time.

i Checked in /usr/sap/IXP/DVEBMGS00/j2ee/cluster/server0/log

I got following information:

But i have already maintained CPIC_MAX_CONV as 2200 at OS Level in .profile.

why did this happen then?

Priya,

Did you reload the env before you restarted SAP.

SAP will pick up the parameters that are used from that session, so just changing it in the env will not cause it to be picked up.

Log out of the session, log back in, do an env|grep -i cpic see if the new value shows up then recycle.

Also please check gw_max* parameters.

Check SAP Note # 316877 and 314530.

Premlesh

Dear Premlesh:

i have put this variable in .profile for the same reason that it should get loaded after every session.

Anyways for New session following is the output:

1. env|grep -i cpic

CPIC_MAX_CONV=2200

other gw_max parameters are as follows:

gw/max_conn=2000

gw/max_conn_per_wp=200

gw/max_overflow_size=10000000

gw/max_overflow_usage=20

gw/max_shm_req=400

gw/max_shm_req_per_conn=10

gw/max_short_poll_no=20

gw/max_sleep=20

gw/max_sockets=2048

gw/max_sys=2000

gw/max_wp=0
