specified in an ALTER CATALOG command.
released { off | on } Tells whether a dump tape’s status changes to Released
(On) or Scratch (Off) when the tape is marked for deletion.
roundrobin ROUNDROBIN attribute setting. If ON, the catalog is
searched in round-robin fashion, so that all tapes in the
catalog are used before any are re-used. If OFF, the
catalog is searched in the standard way, so that the first
available tape after the beginning of the tape list is used.
Last Reel Name (identifier) of tape reel, if TMF has been started and a
tape has been assigned. Otherwise, this field displays the
following information:
“None” if TMF has been started but no tape has been
assigned.
“TMF not started” if TMF is stopping or stopped.
This field only appears if ROUNDROBIN is ON, and is not
generated when the OBEYFORM option is used in the
INFO TMF or INFO CATALOG command.
BeginTrans Configuration
TRANSCOUNTTHRESH
(integer1, integer2)
The upper and lower limits at which the number of active
transactions in the system automatically disables and
reenables new transactions. When the transaction count
reaches integer2, new transactions are disabled. When
the number falls below integer1, new transactions are
reenabled.
TMFLIBMEMTHRESH
(integer3, integer4)
The percentages of processor memory allocated to TMFLIB
that can be used before TMF disables or reenables new
transactions. When the memory used reaches integer4,
all new transactions are disabled. When the memory used
falls below integer3, new transactions are reenabled.
TMPMEMTHRESH
(integer5, integer6)
The percentages of processor memory allocated to the
transaction management process (TMP) that can be used
before TMF disables or reenables new transactions. When
the memory used reaches integer6, new transactions are
disabled. When the memory used falls below integer5,
new transactions are reenabled.
TRANSPERCPU
(integer7, integer8)
The number of transactions that can be started in the
processors on which the TMP is not running (integer7),
and the number that can be started in the processors on
which the TMP is running (integer8).
