Hi Florian, the logpage at the offset 1442 on your logvolume is defect. Because your system is able to restart into online mode, this page is not necessary for the restart. When you initiate the logbackup, then the logpages are checked for consistency. Because this page is not consistent, the logbackup terminates the kernel. I can see that the logpage is defect because there are values shown in the kerneltrace which are inconsistent and should never occur in that combination.
First of all please check the logfiles of your system for hardware errors. The page had been written (if the header is correct) on Jun 11th at 8:25. Also I'd like to know if there had been any administration taken place at this time. To resolve the error, it is neccessary to reinitialize the logvolume. You can do this with the following steps: 1) ensure that a db_online will work 2) enter admin mode 3) complete databackup for security reasons 4) issue the command "util_execute clear log" which will reinitialize the logvolume (and delete everything on it!!) 5) start the database 6) create a complete databackup in order to start the backup-history again 7) if necessary switch on autosave-log kind regards, Martin This page has been written -----Original Message----- From: Florian Schmitz [mailto:[EMAIL PROTECTED] Sent: Monday, June 13, 2005 12:33 PM To: Brunzema, Martin Subject: Re: SAPDBErr Assertion of state Log_SaveIterator::CheckPageBuffer pagebuffer is not inconsistent failed! Hi Martin, see the .prt. The error happens explicitly when writing logbackups. I restored a full backup, the db went online, then i tried a log-backup ... Any Idea?
