How to change password of SYS user on ASM

 

For changing the SYS password on ASM:

In 11.2 we can use asmcmd to change the password as follows · In single instance environment $ asmcmd ASMCMD> passwd sys Enter old password (optional): ****** Enter new password: ****** · In Cluster environment ASMCMD> orapwusr --modify --password sys Enter password: ******

We can not change the password for ASM databases via alter user command.
The password should be the one provided when the password file was created,also REMOTE_LOGIN_PASSWORDFILE should be set to EXCLUSIVE on all instances.

If you want to change the password then you would need to recreate the password file using the orapwd utility
