► Short lock. This is the standard lock normally set

by the TIBCO iProcess Workspace. A short lock is removed

when a user keeps or releases a work item. In the event

that short locks are left behind because, for example, the

iProcess Workspace crashed, the only way to remove the

short lock is to re-start the iProcess Engine or use the

following command.

► Long lock. A lock that is persistent and can only

be removed using sal_llock_frm_init() by the user holding

the lock. Long locks are not normally used by TIBCO

iProcess Workspace, but may be set by SAL SDK programs or

the TIBCO iProcess Objects Client. Re-starting the iProcess

Engine has no effect on long locks, so a work item locked

in this way remains inaccessible to every iProcess user

until it is manually unlocked.
