LEXICON Command Reference Manual
User Defined Attributes : UDAs in User Elements : Purging UDA Instances
Purging UDA Instances
When a UDA definition is deleted, all instances of that UDA will appear to be lost from the databases. However, the database space taken up by the UDA instances will not become usable until the command:
PURGE UDAS
has been given from the user module. The space released is then recoverable when the database is next compacted. Instances will not be PURGEd from locked elements.
Note:
The PURGE command will operate on any UDA instance that it sees as being invalid. This includes any UDA instance which is defined in a deferred LEXICON database. Making the deferred database current will not result in the UDA instances being recovered.
