NAME

pmx-pg-tune - A utility that optimizes shared memory usage for PostgreSQL.


SYNOPSIS

pmx-pg-tune


DESCRIPTION

This command, which is run as the 'pmx' user, works with PostgreSQL 8.x only. You must either run it from the PostgreSQL installation directory (by default, /opt/pmx/postgres) or specify this directory as part of the command.

pmx-pg-tune analyzes system settings and configures shared memory for PostgreSQL in order to improve database performance. If your system settings are not in the recommended range, this command attempts to make the necessary adjustments. In some cases, the updated settings are saved to file named postgresql.conf.recommended. You can accept these settings by renaming the file to postgresql.conf. If your system does not meet even the minimum requirement for shared memory, a error message is displayed.

For more information about the shared memory configuration that is recommended for your operating system, see the article 'Tuning PostgreSQL for PureMessage 5.x' in Sophos's online Knowledgebase.
