J2EE database not available via test

Hi Experts,

I have installed NW 7.0 portal Ehp2 system on Solaris cluster with logical name  . Now when I try to start SAP with the startsap script . it is not starting the database (Oracle) . It just checks whether DB is running and giving message J2EE database not available via test , and asking to check JdbCon.log .

This is Bootstrap log

If I start db manually , then runnig startsap , it runs fine . And also stopsap script , wont stop database .

I checked listener.ora,tnsnames.ora, user profiles, environment variables, permissions etc , nothing found wrong .

When I execute startj2eedb as sidadm , it starts db .

Can you please throw some light on this issue
