Onbar Backups on 9.4

Hi, I have seen strange backup entries in the bar_act.log file on IDS 9.4.UC1 with Veritas 4.5.. Yesterday, I had added new dbspaces to the system... Usually when level-1 onbar backup is inititiated, the system automatically starts Level-0 backup when it sees new dbspaces/or data structure has been changed. But, when level-1 was initiated yesterday after new dbspaces were added, the Level-1 did take place for all the other dbspaces except for the 10 new dbspaces I had added. For those 10 dbspaces, it did level-0 backup... Now that I find strange that the system did not initiate level-1 backups but level-0 for newly added dbspaces and for others level-1. Please let me know if this is something new with 9.4 version becuase in earlier versions had never seen this or some Bug... Thanks Venkatesh Konnur

Nah, it's not anything new with 9.4, I just saw it last week, and we are running XPS 8.32. I added some new dbslices, and it gave me the same message: 2003-08-02 06:02:11 29662 29658 A change in physical configuration has ccurred. A level 0 backup of dbslice_066.1 is being performed. It will also take a level 0 backup of your rootdbspace. Look at it this way - a level 1 is meaningless unless you have a "baseline" level 0 to begin with. In our situation, it did take a level 1 backup of existing dbslices. HTH Milton J. Vidrine, Jr. -----Original Message----- From: Venkatesh K....

Hi, with 9.40.UC1, a couple of improvements regarding this behaviour have been implemented to automate this. In earlier versions of IDS (not necessarily XPS) this was not as nicely and completely automated, that's the reason why you now see these unfamiliar messages in the ON-Bar activity log file. [ Pre-9.40 versions of IDS always printed out the information that a level 0 archive was necessary after adding a dbspace (see the output of "onspaces -c ..." command. However, ON-Bar was relying on the administrator to do these required level 0 archives consciously. Now with 9.40 some mechanism was introduced to do it automatically. I.e. ON-Bar now falls back from requested level 1 or level 2 archive to do a level 0 archive for those dbspaces where this is required. Other dbspaces will be archived as requested. So your observation is correct and you can be assured that the produced archives can be restored correctly. ] Regards, Martin -- Martin Fuerderer IBM Informix Development Munich Data Management Solutions "Venkatesh K...." <VNKONNUR@kcc.usda.gov> Sent by: forum.subscriber@iiug.org 15.08.2003 18:15 To: ids@iiug.org cc: Subject: Onbar Backups on 9.4 [1711] Hi, I have seen strange backup entries in the bar_act.log file on IDS 9.4.UC1 with Veritas 4.5..
