Hello and thank you for reading my post.
My problem is that I do not manage to start a PostgreSQL cluster as a
Windows service.
The OS is WinXP.
- I've created a PostgreSQL cluster "a_pgcluster" with the associated port
5433.
- Running "cmd.exe" under Windows as "a_user", I can start and stop it
manually in command line using the following commands:
- The cluster data directory is "a_pgcluster". Its (filesystem) owner is
"a_user" with this user having "full control" on it.
- Now, I would like it to be run automatically at machine startup as a
service.
- So I registered the cluster using the following command:
- When I go to "Control Panel" -> Administrative Tools" -> "Services" and
try to start the service, I get the following message:
- I also tried the following commands in command-line:
Can you help me try to figure out what's wrong?
Best regards.

Hello Thomas, Contrary to what you say, I provided command lines and messages (in case of failure). What is missing according to you? Thank you and best regards. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Starting-a-cluster-as-a-service-tp5712728p5713039.html Sent from the PostgreSQL - general mailing list archive at Nabble.com.
Hi again, It looks like the problem comes from the "-l" option I'm trying to set when I register the service. 1) If I register the cluster as a service in the following way: It works: the service is automatically started properly. 2) If I add the following option: and then try to start the service (via "Control Panel" -> "Administrative Tools" -> "Services"), it fails with the message: Is this not the right way to set the cluster log file? Or maybe this should be set in the cluster "postgresql.conf" configuration file instead? Thanks for helping.

The command lines. If you did indeed post them, they did not make it to the list. -- If you can't see the forest for the trees, Cut the trees and you'll see there is no forest.
Sorry. I added some "< raw >" tags so maybe this is the reason why you couldn't see half of my message. Hi again, It looks like the problem comes from the "-l" option I'm trying to set when I register the service. 1) If I register the cluster as a service in the following way: ------------------------------------------------------------------------------------------- dos ; a_user> pg_ctl.exe register -N a_pgcluster_srv -U a_user -P a_password -D "a_pgcluster" -S auto -w -t 60 ------------------------------------------------------------------------------------------- It works: the service is automatically started properly. 2) If I add the following option: ------------------------------------------------------------------------------------------- -o "-l '<path_to_the_cluster_log_file>/a_pgcluster.log'" ------------------------------------------------------------------------------------------- and then try to start the service (via "Control Panel" -> "Administrative Tools" -> "Services"), it fails with the message: ------------------------------------------------------------------------------------------- "The a_pgcluster_srv service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service." ------------------------------------------------------------------------------------------- Is this not the right way to set the cluster log file? Or maybe this should be set in the cluster "postgresql.conf" configuration file instead? Thanks for helping.

Hi again, I'm running "PostgreSQL 9.1" under "Windows XP". I'm still trying to set a proper logging system for a PostgreSQL cluster "a_pg_cluster". In the cluster "postgresql.conf" configuration file, I uncommented "logging_connector = on". When I stopped + started the service, I could see a "pg_log" directory had been created with a log file inside. Now, I would like: 1) to store the cluster log files somewhere else say, for example: "C:\postgresql\logs\a_pg_cluster\" 2) to have several small log files instead of a big one and log rotation. Yet, when I set the "log_directory" parameter in the following way: "log_directory = 'C:\postgresql\logs\a_pg_cluster\'" and stop + start the service, it fails with always the same unusable message: "The a_pgcluster_srv service on Local Computer started and then stopped. Some services stop automatically if they have no work to do, for example, the Performance Logs and Alerts service." In the manual, one can read: "When logging_collector is enabled, this parameter determines the directory in which log files will be created. It can be specified as an absolute path, or relative to the cluster data directory. This parameter can only be set in the postgresql.conf file or on the server command line." So, what's wrong with it? I would be happy with the following configuration: logging_collector = on log_directory = "C:\postgresql\logs\a_pg_cluster\" log_filename = 'postgresql-%Y-%m-%d_%H%M%S.log' log_rotation_size = 10MB log_min_messages = PANIC log_error_verbosity = VERBOSE except, it doesn't work... and I'm not sure about the levels "PANIC" and "VERBOSE". Can you help?

Here two thing's, One you should have full access on the directory for Postgres User.
Second, you need to give directory name as below.
log_directory = 'C:\\postgresql\\logs\\a_pg_cluster'
Hello Raghavendra, Sorry for the late answer, I couldn't test this properly before. That indeed solves the problem.
