ok. tomorrow i will check that again. i think that when restore_command was enabled in the slave, the wal receiver proccess didnt appear (and i didnt see the changes inmediately happening in the slave).


I think you should use an other restore_command, in warm standby, the resotre_command will not exit and continue check xlog files and restore them, the streaming won't start when in restore. Try use cp instead of it.

 
can you post your recovery.conf?

primary_conninfo = ''
restore_command = '/opt/omnipitr/bin/omnipitr-restore -l /export/omnipitr/log/omnipitr-^Y^m^d.log -s gzip=/export/vacation_wal_archive -f /export/omnipitr/finish.recovery -r -sr -v -t /export/omnipitr/tmp/ %f %p'                        
archive_cleanup_command = '/opt/omnipitr/bin/omnipitr-cleanup -l /export/omnipitr/log/cleanup.log -a gzip=/export/vacation_wal_archive %r' 
 

thanks for the reply!
