Dbvisit Standby log files

Because Dbvisit Standby runs in the background, log files are an integral part of Dbvisit Standby. There are two log files:

1. The Dbvisit Standby log file (dbvisit.hist)
2. The Dbvisit Standby archive management module (AMM) log file (<DDC>_arch_management.log)

The location of the log files are set by LOGDIR and LOGDIR_DR. The Dbvisit Standby log file will contain a new entry every time Dbvisit Standby is executed. The AMM log file will contain a new entry every time the archive log files are managed by Dbvisit Standby.

Log files are created on both the primary and the standby server. Normal logging is kept to a minimum to allow easy integration with monitoring tools. Once an error is detected, logging is elaborate.

An example of the Dbvisit Standby log file:

Where w102n is the name of the database

The location of the log files are set with the LOGDIR variable for the primary server and LOGDIR_DR for the primary server in the DDC (dbv_DDC.env) file. 

The process id (pid) is shown for each entry. This makes it easy to identify the Dbvisit Standby trace file generated for that entry. For more information about Dbvisit Standby trace files please see the Dbvisit Standby trace files section.
The log files can be read by monitoring tools to provide another level of automatic notification.

To view the log files through the web-based interface go to Home > Logs
Click on Dbvisit log and click View:

Different logs can be viewed including:

1. Dbvisit logs on both primary and standby servers
2. Archive management logs on primary and standby servers.
3. Oracle alert log on primary and standby servers.

Integrating with monitoring tools

The Dbvisit Standby log files can be integrated with existing monitoring tools and the following keywords should be alerted on:

• Error
• Warning (This can be turned off by setting ALERT_ON_WARNING = N)

Maintaining the log files

The Dbvisit Standby log files are automatically maintained on both the primary and the standby servers. For more information please see "Dbvisit Standby log files" under Housekeeping
