Hi,
Currently I am backing up my AIX Oracle DB 11g for system refresh.
These are the steps that I have done so far,
*Few notations that I use are SSID (SourceSID) TSID (TargetSID)
I also taking backup to a shared drive, connected to AIX as CIFS connection.
in the CIFS connection this is the pattern that I followed.
shared_drive/Backup ---> for backup_root_dir & stage_root_dir
shared_drive/Redologs ---> for archive_copy_dir & archive_stage_dir
The following steps I am doing in the Source system (which I am taking the backup from)
1) create control file (alter database backup controlfile to TRACE as '/tmp/SSID.ctrl' ; )
2) copy out control file to pc
3) rename system name to TSID , change the line:
CREATE CONTROLFILE REUSE DATABASE ‘SSID’ NORESETLOGS ARCHIVELOG;
as follow
CREATE CONTROLFILE REUSE SET DATABASE ‘TSID’ RESETLOGS ARCHIVELOG;
4) backup and replace initSID.sap in source system to use share drive as backup by changing following parameters:
backup_type = offline
backup_dev_type = disk
backup_root_dir = Create Backup Folder and provide their path like "shared_drive/Backup"
stage_root_dir = Copy Same Path which you have given to back_root_dir
archive_copy_dir = Create Redologs Folder & Provide their path like "shared_drive/Redologs"
archive_stage_dir = Copy Same Path which you have given to archive_copy_dir
5) use brtools to backup source database
6) backup and replace initSID.sap in target system to use share drive as restore by changing folllowing parameters:
backup_type = offline
backup_dev_type = disk
backup_root_dir = Create Backup Folder and provide their path like "shared_drive/Backup"
stage_root_dir = Copy Same Path which you have given to back_root_dir
archive_copy_dir = Create Redologs Folder & Provide their path like "shared_drive/Redologs"
archive_stage_dir = Copy Same Path which you have given to archive_copy_dir
So in the above steps a few questions,
In step 3 should I change the whole document from SSID to TSID? I mean to say all the files that are pointing to SSID should be changed to TSID or BRTools will take care of that?
Also the backup is going to take 3days?? So does the same steps apply if I am going to do for online backup?
