Hi,
As db2 list db direcory is showing database directory , it means database is there . Problem only it is not known to SAP .
Is SAP server is different than server where Database resides ? in that case we have to install Db2 client also .
But if both SAP and DB2 server is same then seems this problem is with environment variables . Is there some error in sapinst ? since environment variables should set by sapinst .
Could you provide enironement variables realted to db2 and error lines of trans.log ? which will help for troubleshooting.
Thanks
