Level-1 backup after level-0 using ontape

Hi there! I use ontape -s to create archives in order to perform backups. I don't really use any tape device to make the archives. Instead, I have TAPEDEV pointing to the path of a Unix flat file. So, my archives are not segments of tape, but Unix files, one per archive. This schema used to work very well when we had Informix version 7.23. But a problem showed up once we moved to version 7.3: I type ontape -s -L 0 to perform a Level-0 archive. The archive is created successfully and the archive is registered (In onmonitor, the archives register is shown by selecting Status and then Archive). Then, the next day I type ontape -s -L 1 to perform a Level-1 archive. But, even though I see that the level-0 archive was registered, the system displays the following message after I entered the command: Archive failed - No level 0 archive exists; only level 0 archive is allowed. Program over. What could be wrong? What could have changed in the transition from the older version to the newer? I will appreciate any help on this. Thanks.

Check if your level 0 archive is registered there. Level 1 archive requires registered Level 0 Archive information (timestamp - first of all). Also, check consistency for this pages - use 'oncheck -cr'. ---------------------------------------------------- With best regards, Yuri Dovgart SAP R/3, Informix technical consultant, Senior System Consultant System Architecture and High Availability Systems, 'Telecominvest' company Email y_dovgart@tci.ukrtel.net ICQ 39284285

Hi Yuri. Thanks for answering. After making a level-0 archive, the result of 'oncheck -pr' is: --------------------------------------------------------------------------------- Validating PAGE_1ARCH & PAGE_2ARCH... Using archive page PAGE_1ARCH. Archive Level 0 Real Time Archive Began 10/07/99 12:10:08 Time Stamp Archive Began 282010590 Logical Log Unique Id 215 Logical Log Position d58018 DR has not been initialized. --------------------------------------------------------------------------------- It looks like the level-0 archive was registered. The result of 'oncheck -cr' is: --------------------------------------------------------------------------------- Validating PAGE_1ARCH & PAGE_2ARCH... Using archive page PAGE_1ARCH. --------------------------------------------------------------------------------- There is no any error or warning. I will appreciate any additional help from you or from anybody else who is reading this text. Best regards, Sergio Lopez.
