The following are some useful Options relating to the AI Archiver database feature that can be changed while the database is online and the AIMGT daemon is active:
Note: The -aistall parameter will be automatically be set to enabled while the ai archiver is enabled, this is a requirement.
- Re-set the archiving interval online with an active AIMGT daemon,
$ rfutil dbname -C aiarchiver setinterval <n>
The AIMGT daemon executes in 'timed' mode when "n" is a value between 120 and 86,400,
or when n is set to (zero) 0, the archive interval is set to 'on demand' as opposed to 'timed'.
- Change the archiving directory location.
$ rfutil dbname -C aiarchiver setdir <new directory location, full paths, comma separated, no spaces, max 512 chars>
- Stop the daemon running online.
$ rfutil dbname -C aiarchiver end
- Restart the AI deamon online:
$ proshut dbname -C aimgt -aiarcdir <archive-directory-Path> -aiarcinterval n [-aiarcdircreate]
$ rfutil dbname -C aiarchiver disable
- Enable AI Management online
Since OpenEdge 10.1B, AI Management can be enabled online with PROBKUP:
$ probkup online dbname dbname.bak enableai enableaiarchiver -aiarcdir <dir>,<dir> [ -com -vs 250000 -aistall < $BKFILEVOLS ]
- Verify the AI Management status
Since OpenEdge 10.1C, the AIMGT feature can be verified with:
proutil dbname -C describe.
Since OpenEdge 11.3, the archiving mode is additionally reported under the "Details" column.

- Manually Archive Extents online
$ rfutil dbname -C aiarchive nextextent
OpenEdge 10.1B and later: AIARCHIVE NEXTEXTENT will force any FULL extents to be archived online whether the AIARCHIVER is running, or has previously been stopped online with RFUTIL -C AIARCHIVER END for example. It cannot be run offline.
$ rfutil dbname -C aiarchive extent <source-ai-extent> target/aifilename
OpenEdge 10.1B and later: AIARCHIVE EXTENT can be used to manually archive extents when AIMGT is enabled but not running.
AI files can be manually archived and emptied when the AIMGT daemon is
inactive online or after the database has shutdown, offline (and the AI Manager deamon is therefore not running).
AI extents can be archived and marked empty (or Archived in the case they are LOCKED by replication) with RFUTIL AIARCHIVE EXTENT, but not with RFUTIL AIMAGE EMPTY when the AI Archiver feature is enabled.
When used offline, RFUTIL AIARCHIVE EXTENT can be used provided there are sufficient space in the current AI file or enough AI files to switch to in order to record bi recovery Redo and Undo notes. Specify a target directory with sufficient disk space.
