Обсуждение: Stream Replication archive command Access is denied question

I setup my PostgreSQL 9.0.1 Stream Replication.
Here is my config of master database address 192.168.5.4
------------------------pg_hba.conf
# IPv4 local connections:
host    all             all             0.0.0.0/0            trust
# IPv6 local connections:
host    all             all             ::1/128                 trust
host  replication  postgres  0.0.0.0/0  trust
------------------------postgresql.conf
wal_level = hot_standby   
archive_mode = on       
archive_command = 'copy %p D:/3SDATABACKUP/PITR/WAL/%f'        # command to use to archive a logfile segment
max_wal_senders = 5
wal_keep_segments = 32

Here is my config of standby database
------------------------postgresql.conf
hot_standby = on

------------------------recovery.conf
standby_mode          = 'on'
primary_conninfo      = 'host=192.168.5.4 port=5432 user=postgres'
trigger_file = 'standby.stop'
restore_command = 'copy \\192.168.5.4\pitr\wal\%f %p'

Stream Replication work well, every thing I update on master database will exist on standby database.

But on master database log have error

2011-01-01 10:14:19 ICT LOG:  archive command failed with exit code 1

On computer of master database (192.168.5.4), PITR directory only have

D:/3SDATABACKUP/PITR/WAL/000000010000000300000053
D:/3SDATABACKUP/PITR/WAL/000000010000000300000053.00000020.backup
D:/3SDATABACKUP/PITR/WAL/000000010000000300000054
D:/3SDATABACKUP/PITR/WAL/000000010000000300000055
D:/3SDATABACKUP/PITR/WAL/000000010000000300000055.00000020.backup

Please Help me how to fix error on master database and will restore_command on standby database work?

Thanks in advance.

Is by any chance D: a network mapped drive in Windows ?

drive mappings are by user session.   the postgres service is running in
a different user session than your interactive desktop session, so your
desktop shared drives mean nothing to it.

if you're copying across the network, use the UNC name,  like

   archive_command = 'copy %p
//servername/sharename/3SDATABACKUP/PITR/WAL/%f'        # command to use
to archive a logfile segment

and make sure that on the server, there is a postgres user with the same
password as the service account.  or, if you are in an active directory
environment, use a domain account to run the service.

No, D is a driver on master computer. I can copy 000000010000000300000056 file from postgresql data\pg_xlog to D:/3SDATABACKUP/PITR

does the postgres service account have write access to that directory ?


check the access control lists on the directory and parents.  note that
postgres might NOT be a member of 'Users' or other generic groups

Thanks in advance.
When I share D:/3SDATABACKUP/PITR on master computer, I set account postgres only read when access \\192.168.5.4\pitr but directory sercurity of D:/3SDATABACKUP/PITR user postgers has been changed to read only. I had changed directory sercurity of D:/3SDATABACKUP/PITR user postgers to full access. Everything work fine.

Thanks you very much. Sorry for my English.
