Hi List,
I got the logs as below from log file of PGSQL 7.4.2 on Solaris-9. Can any one please give the exact meaning of it. And I have not found the file any where on the server "0000000400000072". LOG: recycled transaction log file "0000000400000072" And I found most of the logged file contains the following statements. LOG: unexpected EOF on client connection WARNING: there is no transaction in progress WARNING: there is no transaction in progress WARNING: there is no transaction in progress WARNING: there is no transaction in progress LOG: unexpected EOF on client connection LOG: unexpected EOF on client connection LOG: unexpected EOF on client connection LOG: unexpected EOF on client connection WARNING: there is no transaction in progress WARNING: there is no transaction in progress WARNING: there is no transaction in progress WARNING: there is no transaction in progress WARNING: there is already a transaction in progress WARNING: there is already a transaction in progress WARNING: there is no transaction in progress Can I get the exact date and time of these logged statements. And what is the meaning of these statements. Regards, G. V.

Hi All! I have configured the warm standby using WAL FILES and DRBD. The wal files are generated as server A. I am using DRBD to replicate these wal files between server A and server B. The DRBD service is running as Primary on Server A and secondary on Server B. The wal_files are written to the server B, but there is a drawback for DRBD. The filesystme needs to be unmounted on the server B (where DRBD is running secondary role). So recovery is not countinuous.(file systme is unmounted). To start the recovery, i need to change the DRBD role to primary on server B. After that i have to mount the filesystem. Once i mount the filesystem, the recovery process starts. Is there any way in which i need not switch secondary/primary role for DRBD on server B? Is there any way in which i can have the file system mounted on server B, running DRBD secondary role? How else can i replicate the wal_files? ( i don't want to user common file system ,,, NFS,,, etc.)? Another thing which i want to ask is that if we are generating archives every 1 minute. then what happens to the data which was written to the server A after 35 seconds after the last wal file generation.(server A crashes). Since this data has not been archived (it was supposed to archive after 1 minute), do i think that this is the loss of data in a server A crash as this 35 second data has not been written to the archived logs and neither has been transported to server B? A quick reply is highly appreciated! Thanks!
