ABAP +JAVA system copy process

Question

Hello All,
We are in process of building a server from a existing ECC 6.0 ABAP + JAVA system.
We are using system copy process where we are restoring ABAP databse from source system.
My question is about the JAVA part.
How can we copy java part? Can we export only JAVA part from ECC 6.0 ABAP +JAVA system and import this to target server.
Please suugest the process.
Regards,
Manish

Hi Manoj,
When you are doing restore of your P(DUAL stack)system then it will automatically restores your ABAP and JAVA scehema table spaces(Normal usage).And If you are using sapinst then take a CI export(for file system/java settings etc) of your source system and then you have to import that in your target system later in the process.So this procedure will automatially serve for both ABAP and JAVA schemas. Importantly this procedue was highly recommended by SAP,so if you run into any issues then you can go ahead and raise a OSS msg.
Other guy already pasted the link for homogenious copy guides
But you can do your java export from command level also(with out using SAPINST) and later you can import it into your target system.This means you are exporting your JAVA schema table space and importing.Keep it in mind that you have to export your Target java scehema not source system .If you do so then its of no use because you have to perform all post steps for java stack also. You can export and import table j2ee table space from your OS level at DB host using "exp javascehma/pwd ........."(not a full fledged command) and then you do the same by perforing "imp........." after restore and recovery from your P(source) system.But this is not at all recommended by SAP but this will work!.
Let every one to know if you need anything more than this.
