System requirements

The target computer on which you are installing the replication components must meet the following memory and disk space requirements:

For Windows

**Table 3-1: Windows memory and disk requirements**
Components	Memory (RAM)	Disk space
Replication Server	512MB	380MB
ECDA	512MB	440MB
Replication Agent	512MB	300MB

For UNIX

**Table 3-2: UNIX memory and disk requirements**
Components	Memory (RAM)	Disk space
Replication Server	512MB	520MB
ECDA	256MB	700MB
Replication Agent	512MB	300MB

For Linux

**Table 3-3: Linux memory and disk requirements**
Components	Memory (RAM)	Disk space
Replication Server	512MB	400MB
ECDA	256MB	590MB
Replication Agent	512MB	300MB

To improve performance by avoiding multiple network hops, Sybase recommends that Replication Server, ECDA for ODBC, and the target database reside on the same machine.
