Oracle Data Guard is a high-availability solution that uses two database servers—the active, primary server, and a standby server that can take over should any problems occur on the primary server. The following tools are available for monitoring an Oracle Data Guard configuration.
| Script | Description | ||
|---|---|---|---|
check_dg_configuration | Used to sanity check an existing Data Guard configuration to see if the init parameters are set as expected. Run this script manually, as necessary. It works only on the primary server.
| ||
| check_standby | Configured through crontab (AS3000) or Scheduled Tasks (AS300) to run daily at 3:45 and 20:15 to detect any archive gaps between the primary and standby servers. If the gap exceeds 20, an exception is sent. This script works only on the primary server. |
