Transaction log maintainance

Question

Hi All,
Is there anyway that i can clear the transaction logs within a specific timeperiod.
My primary objective is to keep this in daily automation so that it will backup the transaction logs for replay transaction and clear the previous logs.

Answer 1

Stop the application and have a script that deletes the files in the transaction log directory.
Or the official Oracle take is :-
*"Periodically, you might want to remove the transaction log store and the files in the Replay directory to increase available disk space on Essbase Server.*
*Transaction log store: Oracle recommends removing the transaction log store for one database at a time. The log store is in a subdirectory under the log location specified by the TRANSACTIONLOGLOCATION configuration setting. For example, if the log location for the Sample.Basic database is /Hyperion/trlog, delete the contents of the following directory:*
*/Hyperion/trlog/Sample/Basic*
*Replay directory: After you have replayed transactions, the data and rules files associated with the replayed transactions can be removed from the ARBORPATH/app/appname/dbname/Replay directory (see Configuring Transaction Replay). You can delete all of the files in the Replay directory, or follow these guidelines for selectively removing files:*
** Remove the data and rules files in chronological order, from earliest to latest.*
** Do not remove data and rules files with a timestamp that is later than the timestamp of the most recent archive file.*
*Note: Oracle recommends waiting until several subsequent database backups have been taken before deleting files associated with transaction logging and replay."*
