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