h1. Test Environment

h2. Virtual Machine description

Test machine is a virtual machine on a ProxMox environment.

Physically stored on inf-proxmox2

VM Name : sdo3

VM id : 801

memory : 32.00GB

CPU : 16 CPUs (4 X 4 cores)

Hard Disk 1 : 64 GB (OS + NetDRMS software) - stored on NFS-HA

Hard Disk 2 : 1 TB (Databases) - Stored localy

Not in HA configuration. VM Backup each day (for OS).

Guest OS : Debian 8.1

Guest kernel : Linux sdo3 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1 (2015-05-24) x86_64 GNU/Linux

h2. Manual install of postgresql

h3. Prerequisites

<pre>

# apt-get --purge remove postgresql*

# wget https://ftp.postgresql.org/pub/source/v9.4.4/postgresql-9.4.4.tar.gz

# tar -xzvf postgresql-9.4.4.tar.gz

</pre>

Before compiling, I verify that patch required by NetDRMS (voir [[ici|http://vso.stanford.edu/netdrms/pginst.html]]) was really present in source files :

_src/backend/utils/misc/guc.c_ and _src/bin/pg_dump/pg_dump.c_

<pre>

# apt-get update

# apt-get upgrade

# apt-get install gcc make libreadline-dev minizip

</pre>

h3. Installation

<pre>

# ./configure

# make

# su

# make install

# adduser postgres

</pre>

h3. Test database

<pre>

# mkdir /usr/local/pgsql/data

# chown postgres /usr/local/pgsql/data

# su - postgres

# /usr/local/pgsql/bin/initdb -D /usr/local/pgsql/data

# /usr/local/pgsql/bin/postgres -D /usr/local/pgsql/data >logfile 2>&1 &

# /usr/local/pgsql/bin/createdb test

# /usr/local/pgsql/bin/psql test

</pre>

h3. Shared postgresql library

<pre>

# vi /etc/ld.so.conf/libc.conf

</pre>

add :

<pre>

/usr/local/pgsql/lib

</pre>

h3. Boot start-up

We create an init script in order to start postgresql on boot

<pre>

# vi /etc/init.d/postgresql

</pre>

Content :

<pre>

#! /bin/sh

# chkconfig: 2345 98 02

# description: PostgreSQL RDBMS

# This is an example of a start/stop script for SysV-style init, such

# as is used on Linux systems.  You should edit some of the variables

# and maybe the 'echo' commands.

#

# Place this file at /etc/init.d/postgresql (or

# /etc/rc.d/init.d/postgresql) and make symlinks to

#   /etc/rc.d/rc0.d/K02postgresql

#   /etc/rc.d/rc1.d/K02postgresql

#   /etc/rc.d/rc2.d/K02postgresql

#   /etc/rc.d/rc3.d/S98postgresql

#   /etc/rc.d/rc4.d/S98postgresql

#   /etc/rc.d/rc5.d/S98postgresql

# Or, if you have chkconfig, simply:

# chkconfig --add postgresql

#

# Proper init scripts on Linux systems normally require setting lock

# and pid files under /var/run as well as reacting to network

# settings, so you should treat this with care.

h3. Install additional modules

Nous avons besoin de dblink pour les trigger entre bases de données

<pre>

root@sdo3:~# cd /Downloads/postgresql-9.4.4/contrib/dblink

make install

root@sdo3:~/Downloads/postgresql-9.4.4/contrib/dblink# /usr/local/pgsql/bin/psql ias_sdo_monitor -p5436 -U postgres < dblink--1.1.sql 

Use "CREATE EXTENSION dblink" to load this file.

root@sdo3:~/Downloads/postgresql-9.4.4/contrib/dblink# /usr/local/pgsql/bin/psql ias_sdo_monitor -p5436 -U postgres

psql (9.4.4)

Type "help" for help.

ias_sdo_monitor=# CREATE EXTENSION dblink ;

ERROR:  type "dblink_pkey_results" already exists

ias_sdo_monitor=# drop table pgWatch;
