ALTER BEGINTRANS
RESET TRANSCOUNTTHRESH selects the originally assigned default limits,
which are 1500 for integer1 and 1600 for integer2.
TMFLIBMEMTHRESH (integer3, integer4)
RESET TMFLIBMEMTHRESH
specifies the upper and lower limits at which the percentage of processor memory
allocated to TMFLIB automatically disables or reenables new transactions. When
the percentage reaches integer4, new transactions are disabled. When the
percentage falls below integer3, they are automatically reenabled, if the other
conditions needed for reenabling exist. You must specify both values in the
command, and integer3 must be less than integer4. The minimum value
allowed for both integer3 and integer4 is 1, and the maximum is 100.
RESET TMFLIBMEMTHRESH selects the originally assigned default percentages,
which are 85 for integer3 and 90 for integer4.
TMPMEMTHRESH (integer5, integer6)
RESET TMPMEMTHRESH
specifies the upper and lower limits at which the percentage of processor memory
allocatable to the TMP’s extended segment automatically disables or reenables
new transactions. When the percentage reaches integer6, new transactions are
disabled. When the percentage falls below integer5, they are automatically
reenabled, if the other conditions needed for reenabling (listed under “Usage
Guidelines”) exist. Because the TMP’s extended segment can grow to about 1
GB, transactions typically are not disabled very quickly. You must specify both
values in the command, and integer5 must be less than integer6. The
minimum value allowed for both integer5 and integer6 is 1, and the
maximum is 100.
RESET TMPMEMTHRESH selects the originally assigned default percentages,
which are 90 for integer5 and 95 for integer6.
TRANSPERCPU (integer7, integer8)
RESET TRANSPERCPU
specifies the number of transactions that can run in TMP and non-TMP
processors: integer7 indicates the number of new transactions that can be
started concurrently in processors where the TMP does not run, and integer8
determines the number that can be started in processors where the TMP runs.
The integer8 count includes any network transactions begun on a remote node
that involve the local node. Neither integer7 nor integer8 can be less than 1
or greater than 1073741824. Because of implementation dependencies, both
integer7 and integer8 must be set to a power of 2; if either value entered
Note. For this and other optional parameters, the originally assigned default is the value
initially assigned to the parameter by TMF. The originally assigned default is used for the
parameter when no one has explicitly specified or altered this parameter’s value in a
previous command. For more information about how defaults are assigned, see Usage
Guidelines.
