LISTLOCKS (LL)

DEADL[OCKS] [, RESOLVE ]

display sets of granted and waiting lock requests that form a deadlock.
Deadlocks might resolve themselves if the waiting requests are using timed
I/O.

Deadlocks usually involve multiple files on multiple volumes. Only deadlocks
that are contained within the specified file-set are detected. Deadlocks that
span multiple systems are not detected.

RESOLVE

allows the user to resolve the detected deadlock. The command displays a
list of transactions and processes that are participants in the deadlock and
prompts the user to select either a process to abend, or a transaction to
abort to resolve the deadlock.

LONG[TX] [ value ]

suppresses the display of short-lived transactions and only shows the
transactions that may indicate a long lock duration.

value

an optional parameter between 1 and 255, specifying a number of minutes.
The default is 1.

Only locks that are held by a transaction that has been active for more than the
specified duration are displayed. No process locks is displayed. The
TXSTATUS information showing transaction lifetime is also displayed.

NOI[TENT]

eliminates the display of intent locks. Intent locks are generally used to prevent
another process or transaction from gaining a file lock while a record lock is
held.

NOP[ROCESS]

suppresses the display of locks acquired by a process (locks on non-audited
files).

NOTRAN[SACTION] | NOTX

suppresses the display of locks acquired by a transaction (locks on audited
files).

SUM[MARY]

displays only the count of record and file locks for each file lock-holder
combination. This applies to BYFILE and BYHOLDER options.
