port: 'undefined' error during create secure store phase

Dear all,

During sapinst create secure store phase  I got the below message

Database Instance( Last error reported by the step: Host: 'xxxoradb01' or port: 'undefined' or dbSid: 'PPD' is in an inconsistent state or undefined.).

I have gone through 562403 - FAQ: Oracle Net and checked the tnsnames.ora file and it looks fine. This is a distributed environment where I am currently in DB instance /NW740SR2/ORA/INSTALL/DISTRIBUTED/JAVA/, This is netweaver JAVA 740SR2.

Any hint.

Regards,
