Hi Naveen,
Try the following:
1. Logon directly as the user sap<sid> at OS level. Does this succeed?
2. Connect to the database as following:
- db2 connect to <sid> user db2 <sid> using <password>
- db2 connect to <sid> user sap <sid> using <password>
Do either of these fail ?
If the password fails then you will need to update it:
1. If OS logon fails perform:
- passwd sap<sid> <password>
2. Then perform the following to update the dscdb6.conf password file:
logon as <sid>adm
dscdb6up sap<sid> <password>
If only the connect to the database fails then only step 2 is needed.
Regards,
Hugo
