Обсуждение: "the database system is starting up"
Hi people, I keep getting this message "the database system is starting up" in the postgres log while system is running in archive recovery mode (warm standby). Stops when system enters production mode. I have checked network traffic, but there is none for port 5432. So it must be something local?

That is ok. pg_standby always waits for the next WAL , so it is always in startup mode. -HTH. -- Devrim GÜNDÜZ PostgreSQL Danışmanı/Consultant, Red Hat Certified Engineer PostgreSQL RPM Repository: http://yum.pgrpms.org Community: devrim~PostgreSQL.org, devrim.gunduz~linux.org.tr http://www.gunduz.org Twitter: http://twitter.com/devrimgunduz

Yeah. Are there any good tools or logging options for determining who/what? As mentioned it seems to be local as there is no traffic on TCP port 5432.

Are there any tools that will help me figure out which process is doing this? lsof -i and netstat -p gave me nothing... Thanks, -dennis

When I start a warm standby I get one such message per second from pg_ctl for one minute; then they stop. Yours keep going indefinitely? If you are using pg_ctl, can you show us the *exact* command used (specifically including the -t parameter, if used)? Does your process list show any pg_ctl instances running while this is happening? -Kevin
Hi, There was no user involved, as far as I can see. The connection attempts are refused at the door :) Mine kept going indefinitely, but by trial-and-error I found the application process causing the connection attempts. Thanks for the input though. -dennis -- Geysir IT dth@geysirit.dk http://geysirit.dk +45 31 51 60 00 On 13/04/2010, at 15.44, Kevin Grittner wrote: > Dennis Thrysøe<dth@geysirit.dk> wrote: > >> Yes, that tells me that connection attempts are from the local >> host on incrementing port numbers for each attempt. > > Is the user your database superuser?
