Using the Lock Cleanup and Recovery Service (IXLRT)

As part of the IXLLOCK interface, connected users to a lock structure can specify 64 bytes of record data to be written in the lock structure. This record data can contain information about the associated resource and its ownership state so that the resource can be recovered in the event of the owning user's failure. The record data entry can also have an associated record data type which can be used to identify the type of data being recorded.

The IXLRT service is the recovery interface to obtain or clean up this recording information in a lock structure. The recording information is associated with a connected locking user. Use the IXLRT macro to request the following:

Create a record data entry and write data to the entry. Optionally, you can assign a record data type to the newly created record data entry.
Read the entire set of record data entries in the lock structure or those associated with a particular record data type.
Read the entire set of record data entries associated with a particular connected user or those associated with both a particular connected user and a particular record data type.
Read a particular record data entry by entry identifier.
Delete all record data entries identified by a list of entry identifiers.
Delete a particular record data entry by entry identifier.
Delete all record data entries associated with a particular connected user or those associated with both a particular connected user and a particular record data type.
Update a record data entry by entry identifier and optionally, assign a record data type to the updated record data entry.
