Creating and Releasing Locks
Use
You can use the locking service to create and release locks.
You do not need this function for the standard running of the SAP Web AS. It is only used for test purposes.
Procedure
In the Visual Administrator choose the locking service and then the Runtime tab page.
Choose the Create / Release Lock tab page.
The following functions are provided:
· Lock
· Unlock
· Unlock all
· Unlock all counts
· Unlock all with wildcards
Lock
Enter an owner, name of the lock, and the lock argument. Select a type for the lock (shared – read lock, exclusive cumulative – write lock or exclusive non-cumulative (enhanced write lock, not cumulative). Now choose Execute to set the lock. To see the lock, switch to tab page Display Locks.
Unlock
Enter the owner, name, and argument and choose Execute. You can use Unlock to lower the cumulation counter of the lock by one. If the lock was not cumulated (cumulation counter = 1), it will be released. If you go into the lock display, you will not see the entry any more.
Unlock all
You can enter only one owner. If you choose Execute, the cumulation counter is lowered by one for all locks belonging to this owner.
Unlock all counts
Works like Unlock, but here the cumulation is set to zero. The lock is released even if it has been cumulated several times.
Unlock all with wildcards
You can an owner’s name that contains wildcards. One asterisk represents one letter only.
For example, there are locks for owner, owner1 and owner2.
If you can enter **ner* and choose Execute, all the locks for owner1 and owner2 are reset.
Display Changes
To see your changes, choose the Display Locks tab page, then Refresh.
