Unlock Time in Seconds
In the software, it can be useful to lock data from the database during a transaction. This is made possible using the following instructions:
- the Lock instruction that carries out a symbol lock
- the With lock clause in a read command
- the Readlock instruction that reads and locks a line in a table
This technical parameter is used to define, when faced with a first failed attempt at locking because another user has already placed a lock, the number of seconds during which the engine automatically repeats its attempt before failing by warning the user via a locking message.
After a first failed lock attempt, it will retry every second for the duration defined by the lockwait value.
Level of localization / Global variable
This parameter is defined at the level Folder.It belongs to Chapter SUP (Supervisor) and the Group PRF (Performances),The following parameters are also associated with this chapter and group :
- AUZMEMO (Create all memos)
- CLOMAX (Max no.)
- LAUNCHSYNC (Sync launch after patch integration)
- MAXSPEACV (Specific ACV limit)
- MAXUPDTRS (Update transaction limit)
- MEMTXT (Size of text memory)
- NBTRABUFF (Number of lines in memory)
- NXTREC (Threshold for last read access)
- ORAOPTMIZ (Oracle optimization)
- ORAOPTNB (Oracle optimization)
- ORATRAPATH (Oracle optimization)
- ROLLBACK (Lock attempts before rollback)
- SELWARN (Limit for control memos)
- TIMOUT (Time limit for response)
The lockwait system variable is associated with this parameter.
