Changed Item Lock Details On V11.0 & V12.0, after upgrading from V10.0 or before
In order to introduce "Enhanced Item Lock Details" on V11, see below, the structures have changed and you need to delete and remake existing "special views" of the Item Lock Table. Assuming your Item Lock "view" file is ILOCKTAB use the following:
DELETE-FILE ILOCKTAB, followed by MAKE-SPECIAL ILOCKTAB ILOCKS
Enhanced Item Lock Details
The special view of the Item Lock Table has been enhanced to include more information. You can now find out which Files and Items are locked, which ports are holding those locks, and which ports, if any, are waiting for the locks to be released. Note that only contended Item Locks are displayed by default - i.e. where a process is waiting on a Lock to become free. To list all currently active Item Locks use SHOW-ITEM-LOCKS. From this you can then add 'port_number', of a locked Item, to a LIST ILOCKTAB in order to see the new File and Item details. For further information look up "ILOCK" in the Index of the Reality On-Line Documentation.
Note: You cannot use the editor to provide an Item Locking test as it prompts the user to exit Items already locked, or to continue without allowing the Item to be filed - i.e. the Item Lock is not taken. A DataBasic program is the easiest to use for testing, using READU commands.
