ORA-01102: cannot mount database in EXCLUSIVE mode

By -
Issue:

Can not Mount database in exclusive mode

On Startup or startup mount getting error

ORA-01102: cannot mount database in EXCLUSIVE mode

Solution:

If Database is

go $ORACLE_HOME/dbs

check if there is any 1K<SID>.dbf file is there
if there is, remove that.
now Make sure that DB is shut down and try to see if any background job is still running regarding the SID.

ps -ef | grep ora_ | grep $ORACLE_SID

Now kill these processes and after killing all these processes try to start the DB

It should work.

Best Wishes,
Nikhil Kumar.

In SAP env connection between DB and app beaks multiple times???

How to set the root password after creating instance on oracle cloud

How to set the root password after creating instance on oracle cloud? since you have created instance on oracle cloud, it requires you private .ppk key file to login from putty you can login on your instance by directly providing that private key. and on Linux/Unix defult user is "opc". since during creation of instance it  will not ask you for  root password. You dont need any password to connect to root. to connect to root type below command as opc user. [opc@sts ~]$ sudo su [root@sts opc]# by this you will login as root. Now change your password [root@sts opc]# passwd Changing password for user root. New password: Retype new password: passwd: all authentication tokens updated successfully. [root@sts opc]# All done. Thanks & Regards Nikhil Kumar.
