We need to reinstall the JAVA part alone in ABAP+JAVA

[Former Member]

Dear Sir/Madam,

We have an SAP ECC 6.0 system with ABAP+JAVA components. Now there are some issue with our Java comp. and I'm unable to start the JAVA engine. As we have done little configuration on JAVA side we are planning to reinstall the JAVA part alone.

1)Can we uninstall the the JAVA Component alone from the ABAP+JAVA Central instance?(Without affecting the ABAP Part)

2)Can we install a new JAVA addin in our existing ABAP+JAVA system?

3)If yes; is there any special steps appart from the master guide "4.4.2 Installing the Java Add-In for an Existing ABAP System" ?

Thank you,

Siju

Hi Siju,

1> Uninstall of Java Addin (stack) is possible.

2> Install a separate Java stack and migrate components.

Procedure is standard as per document.

I would suggest you to troubleshoot why java is not coming up. You can follow the notes/instructions as per the link below and post specific error messages if you need further help.

Thank you for the update,

We have done a Homogeneous system copy from our DEV system to QA system(SAP ECC 6.0 ABAP+JAVA with Oracle 10g)

Our issue is we are unable to connect the VA it shows "Unable to lookup connection default".

We've noticed that the Instance ID in our config tool still shows the DEV Instance ID and the Instance.properties files shows the QA system instance ID.

In our DEV it's given

com.sap.engine.bootstrap.Bootstrap

./bootstrap

ID0035522

and QA it's

ID0031354

In have changed the SID,HOST NAME and Instance ID in the config tool to the QA system param. as per the suggestions in the below link

but still I am unable to connect the VA.

the log JVM_bootstrap.out is given below

Bootstrap MODE:

<INSTANCE GLOBALS>

determined by parameter [ID0031354].

Can some one help me to get the file which has the below path?

"A configuration with the path "cluster_data/dispatcher/ID3135400" does not exist."

Is this value is picked up from Windows registry?

[Former Member]

Hi,

A configuration with the path "cluster_data/dispatcher/ID3135400" does not exist

This is not at file system level. Please open config tool and you will see the above. Is this you want?

[Former Member]

No, you can't. Try to Up your existing JAVA. in what a problem ?

Regards.
