After-image Stall (-aistall)

Use After-image Stall (-aistall) to suspend database activity if all AI files are filled.

Operating system and syntax UNIX / Windows -aistall
Use with Maximum value Minimum value Single-user default Multi-user default
Database Server 1 0 — 0

After-image Stall (-aistall) suspends all database activity if all the AI files are filled, and waits until the next AI file is backed up and marked empty. When the activity is suspended, the following message is written to the database log:

Can't switch to after-image extent filename it is full. (3775)
Backup ai extent and mark it as empty (3776)

Without After-image Stall (-aistall), if all the AI files are filled and OpenEdge cannot switch to an empty one, by default the database shuts down.

When using after-image (AI) files, monitor the status of the files to ensure that you do not attempt to reuse an unavailable file. See Manage the OpenEdge Database for information about using the after imaging feature.

After-image Stall (-aistall) may be modified while your database is online using PROMON or through the _DbParams VST.
