Re: Automatic Failover Hot Standby / Streaming replication



You have to install the postgresql client libraries first, it's missing.

Must be something like:

yum install postgresql9.1-client

But I'm not sure about the right package name.

Hi Matheus,

When I run ;

$ pgpool -v

I have:

pgpool: error while loading shared libraries: libpq.so.5: cannot open shared object file: No such file or directory

Could you please help installing pgpool ?

Thanks,

Wissem,

Execute the command:

$ pgpool -v

And check if you are using the newst version, 3.1.2.

If not, I recommend you to download and compile the pgpool source code by hand (it's easy).

Hello,

To install pgpool, I run this command in my virtual machine (OS: Redhat linux 5);

yum install pgpool-II-91.i386

Is it correct? this will install full and complete pgpool librairies necessary for the Hot Standby / Streaming replication on 2 servers on my machine?

Thanks

Hello,

I am new user of Postgresql, I have successfully set up a Hot Standby / Streaming replication on 2 servers running on Redhat Linux 5 (Postgresql version 9.1).

I need to set up an automatic failover and discovered that there is a tool named; pgpool. I have searched a lot on the net and didn't found a useful article (step by step) to setup it.

Could you please help me and share any useful document with me?

thanks,
