Oracle^® Solaris Cluster Data Service for PostgreSQL Guide

Example: Modifying the PostgreSQL Configuration File

1. Modify the PGROOT and PD_LIBRARY_PATH environment variables according to the needs of your build.

   The databases are stored under /global/mnt3/postgres/data.

   The log is stored under /global/mnt3/postgres/logs/sclog.

   phys-schost-1# PGROOT=/global/mnt3/postgres/postresql-8.1.0
   phys-schost-1# LD_LIBRARY_PATH=/global/mnt3/postgres/postgresql-8.1.0/lib \
   /usr/sfw/lib:/usr/local/lib/usr/lib:/opt/csw/lib
   phys-schost-1# export PG_ROOT
   phys-schost-1# export LD_LIBRARY_PATH

   If you are installing the software in the default directory, set PGROOT to /usr/local/pgsql and LD_LIBRARY_PATH to /usr/local/pgsql/lib:/usr/sfw/lib:/usr/local/lib:/usr/lib:/opt/csw/lib.

2. Copy the PostgreSQL configuration file from the agent directory to its deployment location.

   phys-schost-1# cp /opt/SUNWscPostgreSQL/util/pgs_config /global/mnt3

3. Add this cluster's information to the configuration file.

   The following listing shows the relevant file entries and the values to assign to each entry.

   …
   RS=RS-PGS
   RG=RG-PGS
   PORT=5432
   LH=hahostix1
   HAS_RS=RS-PGS-HAS
   PFILE=/global/mnt3/postgres/RS-PGS-pfile
   …
   USER=postgres
   PGROOT=/usr/local/pgsql
   #PGROOT=/global/mnt3/postgres/postgresql-8.1.0
   PGDATA=/global/mnt3/postgres/data
   PGPORT=5432
   PGHOST=
   PGLOGFILE=/global/mnt3/postgres/logs/sclog
   LD_LIBRARY_PATH=/usr/local/pgsql/lib:/usr/sfw/lib:/usr/local/lib:/usr/lib:/opt/csw/lib
   #LD_LIBRARY_PATH=/global/mnt3/postgres/postgresql-8.1.0/lib:/usr/sfw/lib
   #LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/lib:/opt/csw/lib
   SCDB=sctest
   SCUSER=scusser
   SCTABLE=sctable
   SCPASS=

4. Save and close the file.
