Enscribe / Locks

                                  see System Quirks

 

 

The Enscribe / Locks screen presents file and record lock information similar to the FUP LISTLOCKS command.

 

This screen only functions on systems running G06.26 or later.

 

The information is presented in a tree-view format.  The first level is the file name, the second level a file level or record level type of lock and the third level the locking process.

 

The following are descriptions of the columns:

 

File_Name    = File Name that has the Lock

Lock_Type    = Type of Lock (File or Record)

(Len)-Key    = (length of Key)-Key Value for Key-Sequenced files or

RecNbr       = Record Number for non-Key-Sequenced files

Process_Name = Name of Process that requested the Lock or

process that initiated the TMF transaction

Lock_Granted = Lock is Granted

Lock_Intent  = Lock Intent requested by DP2

TransId      = Transaction ID (if TMF active on participant)

 

The underlying Guardian procedure to return locking information does not include the requesting process name if a Transaction ID is returned.  MOMI queries TMF and requests the process name that initiates the TMF transaction.  This is not necessarily the process performing I/O to the listed file.

 

If a lock cannot be granted, indicated by a space in the Lock_Granted column, then the request is placed in a queue until the lock is granted or the requesting process times out.
