J2E instance 0 seems to timeout and shutdown - why? How to stop this?

[Former Member]

I have installed Web AS 6.40 Sneak Preview, and all is running ok. However, it appears that something automatically shuts down all tasks in the J2E instance 0 periodically.

I examined the Syslog from the SAPMMC console, and in there I found these entries:

I notice that there is a "shutdown timeout" parameter, and it's set to 10000 (don't know what the units are).

Could this parameter setting be what's causing my problem? How can I set the J2E instance up so that it won't, on its own, stop? I've looked at the Visual Administrator, but being new to all of that, didn't see anything that I cared to change without expert advice!

Thanks.

I had the same problem and it was because I've made some changes in the JRE (I replaced some jars); of course, I've solved it, restoring the JRE.

Hi,

I believe that is a problem with memory settings.

Try setting the memory to 512MB. 256 MB is default setting.

I believe this should solve your problem.

Mark this question as answered if this solves your problem.

I'm told that this may be ahppening because of an expired Sneak Preview license.

If this is true, then can I uninstall the Sneak Preview, reinstall and get another 90 days?

What if I don't uninstall/reinstall - can I continue to operate (but suffer the periodic shutdown of instance 0?

Are there any caveats, tips, tricks to uninstallation/reinstallation? (I ask this, becuase the original installation was a painful process, due to conflicts with a concurretnly installed Was 6.20 Test Drive SAPDB.)

And lastly, if I uninstall, do I also have to uninstall NetWeaver Dev. Studio?

Hi David,

From my experience, having the server shut down every 30 minutes renders it pretty much unusable. On our systems, a fresh install of the WAS ( after removing the old one ) did gave us 90 fresh days to try out the WAS.

I would recommend running the UNINSTSAP.EXE program under C:\usr\sap\J2E\JC00 to do the uninstall, which does a magnificent job of wiping clean the previous install. Always remember to restart.

Netweaver Dev. Studio does not seem to be affected by the licensing issue, so I wouldn't bother uninstalling it.
