Re: pgAgent on Macbook

Hi Support,

I have installed pgagent on my Macbok version 10.5.7. It's running on Postgres version 8.2.10. I created the schema and I was able to see jobs node there.

I have not started any daemon as I don't know how to do that.

Could you please provide some instruction on how can I get the pgagent running on my MAC Book. Please let me know if there is a document that I need to follow.

I understand that for Linux, there is a separate binary pgAgent-3.0.0-Linux.tar.gz‎ (415 KB‎)

Do we have anything of this sort for MAC. pgagent worked fine on Windows which is a 32 bit operating system, how about MAC since it is a 64 bit Operating System.

Please guide on this.

Regards
Poonam

We have no documentation on that as this problem is very OS specific.
I'd suggest Googling for information on creating a launch daemon,
which should work fine - an un-tested plist file might look like
(substitute the variables for real values):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

<false/>
<key>Label</key>

<key>ProgramArguments</key>
<array>

<string>-l1</string>

As there is for Mac:
http://wwwmaster.postgresql.org/download/mirrors-ftp/pgadmin3/release/pgagent/pgAgent-3.0.0-Darwin.tar.gz

OS X on any Mac Book will be 32 bit iirc.

Start pgagent with the -f option. It seems that fork without exec
doesn't play nicely in Leopard.

You need -f anyway, when starting using launchd, as launchd process
shouldn't fork/exec as launchd can think they've died and restart.
