Unable to switch on to first first SAP Server

[Former Member]

Hi,

We have 2 SAP Production Servers clustered and we use Enterprise portal. Recently, one of the Production server has rebooted unexpectedly. Since the production servers are clustered, users were not affected because switch over to 2nd production server automatically.

When the first production server is up, I started SAP, however in Enterprise portal, it is still accessing second production server rather than the first production server.

Could any one help on this issue.

Thanks,

Jayachandra

Hi.

Please check following thins:

- Are you able to access the JAVA Start Page of the server with the problem?

-> http://fullqualified.domain.name:5<SYSNR>00

If yes, the engine is running. You can check that via jcmon too (all processess need status "running")

If no, stop the instance and clean the shared memory segments (UNIX: cleanipc <SYSNR> remove). Do it twice to be shure that they are deleted. Restart the engine and control it via JCMON.

If everything is fine but it doesn't work. Do you have a Web Dispatcher to dispatch the Java Engines requests?

Logon to the the WD and check if all instances are available. Maybe you only need to reload the Web Dispatcher Configuration. Normally a "new" instance is detected automatically.

Our 2 SAP Production system which are clustered is AS ABAP system and EP (JAVA) is installed on independent system which connects both ABAP system.

Could you guide me how to check the web dispatcher...

Hi.

I do not understand what you mean...

If you talk of clustering the portal you mean that the portal has a high available db and scs-instance. The central instance does not habe to be high available if you have one or more dialog instances installed on different servers. If you have dialog instances you have to use a WD to dispatch the requests to the different instances.

Did you start the WD from the Kernel directory, from a separate directory or did you install it as a own system?

You need that info to find out where to look if the web dispatcher is running...

Normally cou access the WD via browser. The exact link can be verified in the logs or find out when you run sapwebisp -bootstrap (it depends on the installation method and the fqdn, ports you have used).
