This problem is apply to Oracle Database only.
You want to start your SAP, but you find that the SAP Service doesn’t up.
You have checked that all file system are healthy. When you see from developer trace you find that all work processes are died.
You check from R3trans -d and find that the SAP to Oracle connection is fail as follow:
Then you check from trans.log and find error “Connect failed with SQL error ‘28000’”.
From trans.log above you also read information ORA-28000: the account is locked.
open your SQLPLUS and check the oracle users using command:
SQL> select username, account_status from dba_users;
You will see that user SAPSBM is locked. You have to unlock it so that SAP to Oracle works well.
Issue a command to unlock the user:
SQL> alter user SAPSBM account unlock;
Now check again the user, make sure SAP<SID> is unlocked.
Now you can start your SAP normally as explained in article how to start SAP on windows.
