can not restart server0 in portal after a crash

[Former Member]

Hello

I have Netweaver 7.1 installed. Yesterday as I tried to create an IView

Obviously the portal broke down. In the MMC console I saw that

the server0 was off but the server1 was still running.

I stopped and restarted in MMC console the NWeaver. Unfortunately

Only the server1 is running. Server0 treys running but after some minutes

goes off again!

Although I tried it today again, the log entries are only from yesterday under :

C:\usr\sap\CE1\J00\j2ee\cluster\server0\log

The log says:

624#com.sap.engine.core.locking.impl3.LockingManagerImpl##com.sap.engine.core.locking.impl3.LockingManagerImpl.jenqulib#Guest#328####363a01a0a3a711dd9664000c29b4d234#Thread[SAPEngine_EnquReader,5,main]##0#0#Error##Plain###ReadRunnable: failed to connect to server 81 times#

I hope somebody helps!

Hi,

There is option like

J2E

first instand

second instant.

gust right click on J2E and there is option of starta nd stop.

first stop and wait till all get stop and then start again

i think this might resolve your problem.

It does not help!

1)The JAVA Stack seems has enough memory

(but maybe you tell me in which file i should change it?)

2)The license is ok

3) J2EE -> stop, start does not help

4)Firewall is down

Hello,

How were you able to say that you "seem" to have enough memory for it?

You can adjust the memory settings via the configtool: <drive>:\usr\sap\<SID>\JC00\j2ee\configtool. Select the instance and in the Servers General tab administer the Max Heap Size parameter -- now you should read the SAP Note that I linked to you on my reply for the recommended java sizing recommendations.

unfortunatelly, all recomendation did not help.

Finally I was forced to uninstall and install portal again!

It was an unpleasing attemp!

Similar issue in my case was caused because our SA team deleted the port entry in /etc/services file. It got resolved after I put the entry in /etc/services file :

sapdp68 3268/tcp

Hope this will help .... .

Hello,

Do look into the following:

1) Validity of License (Permanent or Temporary)

2) Memory Settings of your JAVA Stack

3) Firewall Settings that would prevent your server to access ports like (3906/39NN --) <- Though this is kind of unlikely on your scenario since you were able to jump start it for a while.

So, that said, do check on #1 and #2 first.

For JVM settings, check this note:
