SEP AG has discontinued support for obsolete SEP sesam versions. Instructions are still available for these SEP sesam products, however, SEP AG accepts no responsibility or liability for any errors or inaccuracies in the instructions or for the incorrect operation of obsolete SEP sesam software. It is strongly recommended that you update your SEP sesam software to the latest version. For the latest version of SEP sesam documentation, see documentation home.


Overview

PostgreSQL database is required for 64-bit SEP sesam installations. Note that SEP sesam RPM packages already include PostgreSQL server package, however for some older SEP sesam versions, you may have to install the PostgreSQL manually as described below.

The database can be installed on different Linux-based distributions:

  • SLES
  • Debian/Ubuntu/UCS
  • RHEL/CentOS

For details on PostgreSQL backup or restore configuration, see PostgreSQL Backup and PostgreSQL Restore.

SLES-based distributions

The PostgreSQL database can be installed using YaST or other common command line tools (rug or zypper) on the SLES system. For details on the supported SLES versions, see SEP sesam OS and Database Support Matrix.

Installing with zypper

SLES includes the standard tool zypper which is common for package management. With this tool packages can be installed (and uninstalled) in the command line. The package name for the PostgreSQL database is postgresq1-server. The SEP sesam Server package includes all dependencies that are needed for standard SEP sesam Server installation.

To install the PostgreSQL database, use the following command:

kiwi:~ # zypper install postgresql-server

The installation is performed as shown in the output below:

kiwi:~ # zypper install postgresql-server

The following new packages have been installed:
  postgresql postgresql-libs postgresql-server 

Total size of the download: 4,1 M. After the operation an additional 7,1 M will be needed.

Calling: postgresql-server-8.3.7-0.1.1.i586.rpm [fertig (1,1 M/s)]
Installing: postgresql-server-8.3.7-0.1.1 [done]

After successful installation, start the PostgreSQL instance:

kiwi:~ # /etc/init.d/postgresql start
Initializing the PostgreSQL database at location /var/lib/pgsql/data    done 
Starting PostgreSQL                                                     done     

Start SLES 12+ with:

service postgresql start

or

systemctl enable postgresql  

Start PostgreSQL instance automatically:

systemctl enable postgresql                                              

Installing with YaST

It is possible to install the packages by using GUI. You can search for the package and select it by using YaST Package Search. Note that the YaST module is not available by default; the package yast2-packager-webpin must be installed first.

Debian-based distributions

For Debian-based distributions (Debian/Ubuntu/UCS) SEP provides signed Debian repositories for easier package installation, verification and update of the SEP sesam software. For details on Debian packages, see Debian Repository.

Installing with apt-get

Debian-based distribution (Debian/Ubuntu/UCS) includes the standard tool apt-get which is common for package management. With this tool packages can be installed (and uninstalled) in the command line.

The SEP sesam Server package includes all dependencies that are needed for standard SEP sesam Server installation. For details on the supported Debian-based versions, see SEP sesam OS and Database Support Matrix.

To install the PostgreSQL database, use the following command:

root@hostname#: apt-get install postgresql

The installation is performed as shown in the output below:

root@hostname#: apt-get install postgresql

RHEL/CentOS-based distributions

Installing via yum package manager

Installing in RHEL- or CentOS-based distributions is similar as in SLES or Debian. All RHEL- and CentOS-based distributions include the standard tool yum which is common for package management. With this tool packages can be installed (and uninstalled) in the command line.

The SEP sesam Server package includes all dependencies that are needed for standard SEP sesam Server installation. For details on the supported RHEL/CentOS-based versions, see SEP sesam OS and Database Support Matrix.

To install the PostgreSQL database, use the following command:

# yum install postgresql-server

The installation is performed as shown in the output below:
