Auto Sync for Password Files in #Oracle 12c Data Guard

sync

A useful enhancement in 12cR2 is that password files are automatically synchronized in a Data Guard environment:

[oracle@uhesse1 ~]$ dgmgrl sys/oracle_4U@cdb1

Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production

SQL> alter user sys identified by oracle;

User altered.

SQL> connect sys/oracle@cdb1 as sysdba
Connected.
SQL> connect sys/oracle@cdb1sb as sysdba
Connected.

I have just changed the password of sys on the Primary and it got automatically also changed on the Standby. In earlier versions that had to be done manually, typically by replacing the password file on the standby with a new copy from the primary. One little thing less to keep in mind now 🙂
