My database cant be restart : sculkget: failed to lock

Hello everybody,

I have a problem with the restart of my databse.

All night we shutdown it to do a backup but when we want to restart, we have this error message :

sculkget: failed to lock /oracle/v10gR2/dbs/lkinstS3G exclusive
sculkget: lock held by PID: 14673
Oracle Instance Startup operation failed. Another process may be attempting to startup or shutdown this Instance.
Failed to acquire instance startup/shutdown serialization primitive


The database can not restart and we have to do a shutdwon immediate then a startup.

The database is ok after that but I will that the database can start without human interaction.

I have found some topics on Internet but I don't find some interesting things. Could you help me please ?

You need to look at the alert log before you issue the second shutdown command. My guess is that the database is not shutting down completely which is leaving some processes behind. Also make sure that all of you scripts have exactly the same environment scripts. If your database starts with ORACLE_SID=MYSID but your scripts have ORACLE_SID=mysid, your script will look like it is shutting down the database, but it won't. the sid name is case sensitive in Unix/Linux.
