Displaying Configuration Attributes
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).
AUTOABORT The length of time that a transaction can run before TMF
automatically aborts it.
RECRMCOUNT For heterogeneous transactions, the maximum number of
recoverable resource managers that can be registered for
the entire TMF system (spanning a single EXPAND node).
RMOPENPERCPU The maximum number of recoverable and/or volatile
resource managers that can be open for each CPU.
BRANCHESPERRM The maximum number of transaction branches that can be
imported or exported concurrently by each recoverable or
volatile resource manager.
