5. Network Requirements
Dbvisit Standby supports two methods of communication between the primary and standby database servers:
- Dbvnet (default) and,
- SSH (Recommended for Solaris and AIX and also fully supported for Linux based systems)
- Note that XCOPY has limited support on Windows-based systems
It is important to make sure sufficient bandwidth is available to cater for your required Recovery Point Objective (RPO) as well as the Recovery Time Objective (RTO).
Dbvisit Standby can make use of compression (highly recommended) to ensure more effective use of bandwidth. Compression can be enabled either during network transfer (making use of Dbvnet compression / or SSH compression), or you can enable compression of Archive logs prior to being copied between the primary or standby servers.
It is recommended you test your network to make sure it can handle the required redo generation rate and that you do not have any network throttling such as packet shaping causing undesirable results affecting your RPO/RTO.
