Unable to start Java Engine on a dual stack (ABAP+JAVA)

[Former Member]

Hi Gurus,

Scenario: Windows Server 2003 with Oracle 10g, SAP Netweaver 2004s

I have uninstalled JSDK 1.4.2_16 and installed JSDK 1.4.2_17 due to unavailability of Java web start on the physical server.

Now when i start the Instance, I am only able to start the ABAP Instance, java instance is not starting up.

I have made the changes in the Envoirenment Variable JAVA_PATH and PATH.

I have also made the changes in the instance profile for the startup JAVA PATH

Is there anywehere else do i need to make the changes??

but still i am not able to start it, Can some please help me on this.

Refer to the below logs of dev_jcontrol

Hi Shrikishan,

Problem resolved, it was due to JDK Version mismatch, I had installed 64 bit JDK on 32 Bit OS.

Thanks for your help

Hi,

While uninstalling and installing, did you change the path of JDK to some new directory. If yes, then perform the following steps:

1. Take a backup of the instance profile and add

jstartup/vm/home = C:\j2sdk1.4.2_17

2. SET JAVA_HOME to C:\j2sdk1.4.2_17

3. Remove

/usr/sap/<SID>/<INSTANCE>/j2ee/cluster/instance.properties.vmprop

/usr/sap/<SID>/<INSTANCE>/SDM/program/config/sdm_jstartup.properties.vmprop

4. Start SAP

Hi,

Error mentions "Cannot load DLL for Java VM".

Same symptom is referred to in Note 940893. Could you try section 2 of the note? Deleting the *.vmprop files so that they are recreated.

Also please check the compatibility of JDK used and SAP system. If SAP system is 32 bit, then 32bit JDK would be required. Incase the system is 64 bit, then JDK required would be 64 bit.

Regards,

Srikishan
