Monitoring and adjusting automated AI File Management
Once you have started automated archiving of your AI extents, you need to monitor the performance of the daemon and the capacity of your archive directories. RFUTIL provides you with qualifiers to modify your archive process online. The following commands continue with the example started in the previous section.
To modify the directory list where your AI extents are archived, use the following command:
The directories specified with this command replace any previously specified archive directories. If the directories do not exist, you can add an additional parameter, -aiarcdircreate, to instruct the AI file management utility to create the archive directories.
To modify the time interval for your AI file management utility daemon, use the following command:
rfutil mydb -C aiarchiver setinterval 600
This command increases the timer of the file management daemon to five minutes.
To force the next FULL AI extent to be archived immediately, use the following command:
rfutil mydb -C aiarchive nextextent
This command archives the next FULL extent to the previously specified directory list. If the daemon is operating in timed mode, the timer is reset. If your database stalls because all your AI extents are full, this command will free an extent. After clearing the stall, set the archive interval to a smaller number or to 0 prevent another stall.
