Guillaume,
Well I could shortly describe what's happen on these machines ; On May 7 2008 at 23:25 an operator performed : _a configuration change ; _add a new user on a table named MVNO; Customer told us that for "new user" operator add comma "," symbol. This is something new for their provisioning procedure (it's seems they never test it )thus as soon as they propagate this updated DB over machines of live net these started to discard all the requests and no more user was able to work or work properly . Now they asking us what's happen so this is the reason why I'm writing here . Unfortunately I tried to verify the backup db but the one interesting for us is empty : ls -l 200805* -rw-r--r-- 1 root root 842840 mag 1 04:03 20080501-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 842840 mag 2 04:03 20080502-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 842840 mag 3 04:03 20080503-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 842840 mag 4 04:03 20080504-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 842540 mag 5 04:03 20080505-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 842613 mag 6 04:03 20080506-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 842613 mag 7 04:03 20080507-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 0 mag 8 04:03 20080508-0403-cfg_xxxxxxx.sql -rw-r--r-- 1 root root 843960 mag 9 04:03 20080509-0403-cfg_xxxxxxx.sql I'll try to find it but but even if I can't provide this back-up for company policies reason , could I ask you some feed-back to get suggestion to look for on this back-up file? Many thanx anyway for your help Best Regards Alessandro. -----Original Message----- From: Guillaume Lelarge [mailto:[EMAIL PROTECTED] Sent: venerdì 9 maggio 2008 19:05 To: MARIOTTI, Alessandro (Alessandro) Cc: [email protected] Subject: Re: [ADMIN] debug issue on postgresql MARIOTTI, Alessandro (Alessandro) a écrit : > I'm writing you to get some information regarding the possibility to get > some information a db corruption got yesterday morning in a live platform . > > We realized DB Inconsistence and corruption and we tried to restore > immediately the DB , via a back-up procedure, to restore services for > customer. > > Now we need to investigate on DB what it was the route cause for db > corruption. > Do you have a backup of the corrupted database ? If you don't, it will be extremely hard to tell you anything interesting.
