Kirti, If the retension period change has to be performed for all nodes in this domain (I hope those nodes are Oracle only) the copygroup has to be updated. If only one node needs this change I would suggest you to define new domain with appropriate ARCHRETension setting, rename the node to <orasrv>_old, re-register the node again and move the node to this domain (UPDate Node <new_name> DOMain=<new_domain>). Old archives will stay as new name, new archives will go to re-registered old_name. You *CANNOT* rebind archives, only backups can be rebound. If you change the mgmtclass in inclexcl list old archives will stay with old class (and short retension) and new archives will be made with new class (and long retension). All those tasks have to be done at the TSM server. You are writing about "SAs". If this is Storage Administrators, i.e. TSM admins, they have to do it. Being only a user of TSM you can only retrieve and re-archive. Somebody still should define the longer retension management class. TDP for Oracle in very simplified overview may be thought as interface wrapper. RMAN calls TDPO through Oracle specified APIs, TDP transforms the request to TSM APIs and calls TSM API client, TSM API client moves the data to TSM server. It is separately priced product and for small Oracle installations and those which allow off-line backup some customers prefer not to buy it and use only B/A client. Oracle DBAs for sure should know if you have it because RMAN has to be configured to use TDPO.

We have archived a number of files for an Oracle database with the default setting for the Management Class (4week retention). The need is to make sure this set is preserved beyond the 4week retention time. Thanks. - Kirti
