I created a physical standby to our primary. I used duplicate from backup to preform this duplicate. The duplication process took rman 12 hours. After the duplicate finished I configured the broker. Then I realized that I have a transfer lag because during those 12 hours I have backed up all the archives in my primary with the next script :
run
{
ALLOCATE CHANNEL CH1 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL CH2 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL CH3 TYPE 'SBT_TAPE';
ALLOCATE CHANNEL CH4 TYPE 'SBT_TAPE';
BACKUP ARCHIVELOG ALL DELETE INPUT;
RELEASE CHANNEL CH1;
RELEASE CHANNEL CH2;
RELEASE CHANNEL CH3;
RELEASE CHANNEL CH4;
}
Therefore, I restored the needed archives and I also configured : CONFIGURE ARCHIVELOG DELETION POLICY TO applied on standby.
I had some problems with my dr so I stopped the transport and the apply in the dgmgrl prompt. After that I configured:
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE;
Now, when I run the archives backup script (every 4 hours) it doesn't delete the archives that it backed up. As a result of that every 4 hours I backup archives that were already backed up. Can someone explain to me what went wrong ?
