Dear All I am a new user of informix v9.4. Can someone help me with the following. We have added some new tables to our database, is it necessary to perform a level 0 backup? Can we perform the level 0 backup while the system is up and receiving the transactions. ( I was asked to bring down the application and bring down the database and bring the database up only, without bringing up the application and perform the level 0 backup) regards

Yes, Informix supports a hot backup. You can run it while other users are on the system. Check out ontape and onbar. You don't HAVE to run a backup after creating tables, but backups are generally a good idea. j. -----Original Message----- From: ids-bounces@iiug.org [mailto:ids-bounces@iiug.org]On Behalf Of SYED ALI Sent: Monday, May 14, 2007 3:57 PM To: ids@iiug.org Subject: INFORMIX LEVEL 0 BACKUP [9145] Dear All I am a new user of informix v9.4.

Hi Syed, Informix performs on-line backups. What this means is that you can take a backup while the instance is performing it's normal operations. Are you planning on using onbar or ontape? ----- Original Message ---- From: SYED ALI <syed_mohsin@excite.com> To: ids@iiug.org Sent: Monday, May 14, 2007 2:57:06 PM Subject: INFORMIX LEVEL 0 BACKUP [9145] Dear All I am a new user of informix v9.4.

If your onconfig file parameter LTAPEDEV points to something else than /dev/null you can apply logical logs in case of a restore (restore level 0 backup and apply logical log restore afterwards). In that case a level 0 backup and the logical logs are sufficient. To take the level 0 backup you MUST use one of the informix utilities ontape or onbar and these are always 'hot backups'.
