Notes
There is a number of changes being introduced with each update. Some updates may come with specific requirements.
- Please note that Dbvserver (Central Console) will not be able to install on Solaris and AIX based systems.
- The Central Console must be installed on a Linux or Windows based system (Linux recommended).
- Dbvisit Observer (Auto-Failover tool) must be installed on a Linux or Windows based system only.
2. Known Issues
It is possible that some of the release updates will include known issues. This section should be reviewed for any new release.
2.1. Solaris and AIX
It is important to take note of the following:
- Dbvisit Standby can be installed and used on Solaris based systems (Solaris 10+) with the exception that the Central Console (Dbvserver) must be installed and running on a Linux or Windows-based system.
- Dbvserver (Central Console) cannot be installed on Solaris and AIX based systems.
- Dbvisit Observer (Auto-Failover tool) cannot be installed Solaris and AIX based systems.
2.2. Windows
- Dbvisit Standby currently only supports ipv4, not ipv6.
- It was noted that on windows ipv6 may be favoured and if the hostname resolution is not ipv4, Dbvnet, Dbvserver and Dbvagent might listen on ipv6 when started.
- It is recommended to make sure the hostnames used in the Dbvisit Standby configurations, resolve to an ipv4 address and not ipv6.
- If Dbvnet, Dbvserver and Dbvagent are not able to listen on ipv4 due to name resolution favouring ipv6, you will have to make use of ipv4 IP addresses in the Dbvnet, Dbvagent, Dbvserver configuration files as well as your Dbvisit Standby DDC file (for the SOURCE and DESTINATION)
- Using the following commands after starting Dbvnet, Dbvagent and Dbvserver, you will be able to identify if it is listening on ipv4 or ipv6:
- Dbvnet: netstat -an|findstr 7890
- Dbvagent: netstat -an|findstr 7891
- Dbvserver: netstat -an|findstr 4433
3. Change Log
Important Notes
- Oracle 10gR2 (10.2.0.5) is now supported - using the latest patch set 10.2.0.5 is required
- IMPORTANT:
- This excludes Oracle 10g RAC configurations which are not supported
- If using Oracle ASM - the version of ASM must be 11.2 and above (Graceful Switchover will not be possible if ASM version of 10.2 is used)
- IMPORTANT:
- Using SSH as communication between primary and standby hosts are fully supported. The default is to use Dbvnet, but SSH passwordless communication is still supported.
- The Linux downloads are combined into one download. The installer download will be in the form of "dbvisit-standby9.0.02-linux.zip" . There will only be one download which can be used for all the supported Linux versions (SLES, Red Hat and Oracle Linux):
- Oracle Linux 5, 6 and 7 (64 bit)
- Red Hat 5, 6 and 7 (64 Bit)
- SLES 11 and 12 (64bit)
