Hi,
I am attempting to use the WAL archiving on a Solaris machine, running
PostgreSQL 8.1.4. The archive_command specified in the
postgresql.conf file does not get executed, nor do I see any log
entries showing errors etc. What am I doing wrong here?
Here is the relevant fragment of my conf file:
fsync = on # turns forced synchronization
on or off
wal_sync_method = fsync # the default is the first option
# supported by the operating
system:
# open_datasync
# fdatasync
# fsync
# fsync_writethrough
# open_sync
#full_page_writes = on # recover from partial page writes
#wal_buffers = 8 # min 4, 8KB each
#commit_delay = 0 # range 0-100000, in microseconds
#commit_siblings = 5 # range 1-1000
# - Checkpoints -
checkpoint_segments = 1 # in logfile segments, min 1, 16MB each
checkpoint_timeout = 30 # range 30-3600, in second
checkpoint_warning = 5 # in seconds, 0 is off
# - Archiving -
archive_command = 'touch /var/lib/pgsql/bkp/myfile'
Here is my log entry for the duration of the test:
FATAL: terminating connection due to administrator command
LOG: shutting down
LOG: database system is shut down
LOG: database system was shut down at 2007-06-19 07:48:03 EDT

Thanks in advance,

Looks like you are expecting the archive command to run when you shut
down the data base. It won't. It only runs when the xlog gets full and
the system needs to recycle to a new logfile.
FWIW, here's what my solaris 9, posgresql 8.1.8 system has as an archive
command:
archive_command = 'test ! -f
/data/archivelog/%f && cp %p /data/archivelog/%f'
adjust as needed for your directory structure.
you need to run enough commited transactions through to fill up a 16 meg
xlog. Then you will see the xlog getting archived (or your "myfile" get
updated).
