missing:..........appl/alr/11.5.0/admin/driver/alrfile.drv

I have certain patch to apply in my system, but unfortunately adpatch is coming out with following error for any patch.
Determining valid on-site files...
AutoPatch error:
The following file is missing:
..........appl/alr/11.5.0/admin/driver/alrfile.drv
AutoPatch error:Error reading product file driver files complete; make tapes
AutoPatch error:Error determining valid on-site files
You should check the file..........................appl/admin/SID/log/logfile.log for errors.

===============================
No answer in metalink for this. I did find for alrfile.drv in my system and did found the file in $APPL_TOP/amf/alr/11.5.0/admin/driver/alrfile.drv, just created softlink for alr under $APPL_TOP like
ln -s amf/alr alr
and reapplied the patch and it worked.

Happy Troubleshooting !!!

Changing Data Guard Protection level

We are in process of testing Data Guard setup. While doing that I come across a situation where I have to change Protection status from status from Maximum Performance to Maximum Availability:
On Primary:
alter system set log_archive_dest_2='SERVICE=Instance_Name LGWR SYNC AFFIRM valid_for=(ONLINE_LOGFILES,PRIMARY_ROLE) db_unique_name=SID;
alter system set log_archive_dest_state_2=enable;


Shutdown and mount the primary and standby database:
SQL> -- [Connect to the primary database]
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP MOUNT

SQL> -- [Connect to the standby database]
SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP NOMOUNT

On Primary
ALTER DATABASE SET STANDBY DATABASE TO MAXIMIZE AVAILABILITY;

On Standby
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;

On Primary
ALTER DATABASE OPEN;

SQL> SELECT PROTECTION_MODE, PROTECTION_LEVEL, DATABASE_ROLE FROM V$DATABASE;

Forgotten wallet manager password

We all know that wallet is secured with password. We need password to opne wallet and include some more certificates or for some admin work. But what if we forgot its password. Can we reset its password ? Answer is NO. So please do remember this wallet manaager password otherwise you have to redo all your work for wallet.
As per Metalink Note : 367755.1
"Unfortunately there is nothing that can be done here.
If the Wallet password is lost, a new Wallet and Certificate Request need to be created. Then a new certificate from this Certificate Request would need to be generated, and then imported to the new wallet."

Happy Troubleshooting !!!
