Hi Rajesh,
The problem seems to be in
OraCom.trace("OraCom._isClientLink (start): ", src); <<<<
Which means argument "src" was null when passed to function _isClientLink.
This function calls another one (getOclDirFromFile), which basically tries to search the Oracle client
at file system level.
So probably, sapinst was not able to extract the Oracle client. I would recommend you to check if the OCLxxx.SAR file exists in the directory mentioned in the sapinst_dev.log. If so, set permission 777 to the entire /sapcd directory recursively, using: chmod -R 777 /sapcd
After that, restart sapinst, choose the same options in the initial dialog and select "continue with old option".
Hope this helps you.
Regards,
Hugo
