hi, i had made necessary change in the postgresql.conf for enabling WAL. How can i know that WAL is working? The configurations done in the postgresql.conf file is as below: #--------------------------------------------------------------------------- # WRITE AHEAD LOG #--------------------------------------------------------------------------- # - Settings - fsync = true # turns forced synchronization on or off wal_sync_method = fsync # the default varies across platforms: # fsync, fdatasync, fsync_writethrough, # open_sync, open_datasync wal_buffers = 8 # min 4, 8KB each commit_delay = 0 # range 0-100000, in microseconds commit_siblings = 5 # range 1-1000 # - Checkpoints - checkpoint_segments = 3 # in logfile segments, min 1, 16MB each checkpoint_timeout = 300 # range 30-3600, in seconds checkpoint_warning = 30 # 0 is off, in seconds # - Archiving - archive_command = 'cp -i %p /testpg/server/archivedir/%f </dev/null' your response will be highly appreciated. thanks -- View this message in context: http://www.nabble.com/WAL-tf3685432.html#a10301494 Sent from the PostgreSQL - general mailing list archive at Nabble.com.
