tcl.txlog

Verb: Access/TCL, Releases: AP

Invokes transaction logger menu.

Description

invokes a menu for administration of the transaction logging subsystem.

When active, transaction logging logs all updates to files which have been marked for participation in logging. This involves changing the 'd-pointer' to the file to 'dl'. This can also be indicated when creating the file by using the 'l' option. Logging may go directly to magnetic media, or held in a file until the media can be attached.

Logging, or enqueing, occurs constantly in files that are marked as participants in transaction logging by having a 'dl' designated in the 'd-pointer' (attribute 1). 'dequeing' occurs when transactions are being dumped to magnetic media.
