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:
The Dbvisit Standby log file (dbvisit.hist)
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:
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

Maintaining the log files
