NAME

watchdog_setup - Create a temporary installation of Pgpool-II clusters with watchdog

SYNOPSIS

watchdog_setup [option...]

DESCRIPTION

watchdog_setup creates a temporary installation of Pgpool-II clusters with watchdog enabled, which includes a Pgpool-II installation and specified number of PostgreSQL installations under current directory. Current directory must be empty before running watchdog_setup.

watchdog_setup is for testing purpose only and should not be used to create production installations. Also please note that heartbeat is not used.

watchdog_setup uses pgpool_setup(1) as a workhorse.

Currently watchdog_setup supports streaming replication mode, snapshot isolation mode, native replication mode, logical replication mode and raw mode.

OPTIONS

watchdog_setup accepts the following command-line arguments:

-wn num_pgpool

Specifies the number of Pgpool-II installations. If this is omitted, 3 is used.

-wp watchdog_base_port

Specify the starting base port number used by Pgpool-II and PostgreSQL. For the first Pgpool-II, Pgpool-II port is watchdog_base_port. pcp port is watchdog_base_port + 1, watchdog port is watchdog_base_port + 2. wd_heartbeat_port is watchdog_base_port + 3 (though heartbeat is not used). The first PostgreSQL node's port is watchdog_base_port + 4, second PostgreSQL node's port is watchdog_base_port + 5 and so on.

If this is omitted, 50000 is used.

-m mode

Specifies the running mode. mode can be r (native replication mode), i (snapshot isolation mode), s (streaming replication mode), l (logical replication mode) or n (raw mode). If this is omitted, s is used.

-n num_clusters

Specifies the number of PostgreSQL installations. If this is omitted, 2 is used.

--no-stop

Do not stop pgpool and PostgreSQL after the work.

-d

Start pgpool with debug mode.

ENVIRONMENT VARIABLES

watchdog_setup recognizes following environment variables:

PGPOOL_SETUP

Specifies the path to pgpool_setup command. The default is "pgpool_setup", thus it is assumed that pgpool_setup is in the command search path.

PGPOOL_INSTALL_DIR

Specifies the Pgpool-II installation directory. Pgpool-II binaries is expected to be placed under PGPOOL_INSTALL_DIR/bin and pgpool.conf and pool_hba.conf etc. are expected to be placed under PGPOOL_INSTALL_DIR/etc. The default is /usr/local.

PGPOOLDIR

Specifies the path to Pgpool-II configuration files. The default is PGPOOL_INSTALL_DIR/etc.

PGBIN

Specifies the path to PostgreSQL commands such as initdb, pg_ctl and psql. The default is /usr/local/pgsql/bin.

PGLIB

Specifies the path to PostgreSQL shared libraries. The default is /usr/local/pgsql/lib.

PGSOCKET_DIR

Specifies the path to Unix socket directory. The default is /tmp.

INITDBARG

Specifies the arguments for initdb command. The default is "--no-locale -E UTF_8".
