Replication Server System Database Location

Replication system data is stored in a dedicated Adaptive Server Enterprise database called the Replication Server System Database (RSSD), or in an embedded Replication Server System Database (ERSSD) using SQL Anywhere®.

RSSD must be actively managed, while ERSSD is automatically created, configured, and maintained by Replication Server. If you choose to use RSSD, it is created when the Replication Server is installed.

Before you begin the installation, decide which Adaptive Server will store the RSSD for the Replication Server and the devices on which the database and its log will be stored. You can create the Adaptive Server database devices during installation, but identify their physical disk location before you install the Replication Servers.

If you use ERSSD, decide the directory paths for the ERSSD database file, transaction log, and backup. For better performance and recoverability, the database file, transaction log, and backup directory should be on different disk devices.

Note: ERSSD requires Sybase SQL Anywhere. SQL Anywhere version 11 included with Replication Server 15.5 and later is available on, 32-bit and 64-bit Windows, 32-bit and 64-bit Linux, 64-bit Sun SPARC, 64-bit Sun Solaris x64, 64-bit HP Itanium, and 64-bit IBM AIX platforms.

The ERSSD, Sample Replication Server, and ASA11 folder are not available on 64-bit Linux on POWER (IBM pSeries).
