java splitting- heterogeneous system copy

[Former Member]

hi ,

i am using nw70 installation master with latest version sapinst. i am doing source system export - oracle - as abap and java. when i choose table splitting i find only abap splitting options. how do i do the java table slitting. the java export is taking too long and i want to split the java export dumps.please advise

is there a option in sapinst to do java splitting?

Thanks

hi

yes splitting of tables for a java export is possible. you can find the relevant tools and documentation in this location of your sap instance.

/usr/sap/<SAPSID>/SYS/global/sltools

Thanks Amit

I don't find this in the location mentioned

Can I download it from sap?

How do I do this with sapinst

I am having a dual stack system running as abap and java export

Should I run just as abap seperately and then do the jsplitter method ?

Please advise

Thanks

Sorry i did not realize it was a dual stack system. I have done table splitting for AS Java systems and havent seen any issues.

here is what i found for dual stack db independent system copies. i have never tried it but i think this is what you are looking for.

i would also recommend to check the system copy guide .

Hi Joyce,

The JAVA splitter is available only since NW 7.02 (NW 7.0 EHP2). You mentioned you are using NW 7.0 Installation master (as your system in NW 7.0) so that explains it.

Hi Joyce,

Not sure if you've gotten anywhere with this thread but if I understand your issue correctly, you would like to remove/split off the JAVA stack from the ABAP.  If that is correct, have you looked into using the Dual Stack Split Tool?  We recently began looking at splitting off our JAVA stack from ABAP in the BI environment and while it was a proof of concept for future needs, it did work out.  It may assist you in your efforts.

Thanks erin.

i was not spliiting java from abap+java stack , i wanted to know if we can do java table splitting or some kind of splitting as we do for abap export to reduce java export time in a heterogeneous system copy. looks like we do not have java table splitting for nw70. correct me if i am wrong.

thanks
