java not coming up after system refresh

[Former Member]

Hi,

We have recently done a EP system refresh to a new system. This one

is NW700 with SPS18. The import finished succesfully with out any

issues after the system is not coming up and jcontrol process shows

some process running and dispatcher, server0, server1 shows waiting for

start.

I have done the following things from my side after the import.

1) Tried to increase & decrease the heap size & bootstrap settings

using VA tool.

2) Matched the instance.properties with source and adjusted as it looks

like source system.

3) replaced the configtool lib files with the latest SP to see if there

is any secstore issues.

4) Upgraded the kernel as source sysem.

Still all of them didn't solve my problem. Attaching the logs of dev_server0

Hello Krishna

It looks like your -Xdump parameter is incorrectly set.

Can you verify please?

JVMDUMP014E VM Action unrecognised: ...prewalk

The right action is normally prepwalk.

Reference: SAP Note 1439020 - Windows Java instance start fails due to Unrecognized option

You might or might not be running on Windows but a parameter with an unrecognized option = Java does not start.

Kind regards

Tom
