CEMT INQUIRE TCLASS
CEMT INQUIRE TCLASS
Function: Retrieve information about tasks within a task
class.
Description: INQUIRE TCLASS returns information about
the current and maximum number of tasks, the purge
threshold, and the status of a user-defined task class.
Input: Press the Clear key to clear the screen. There are
two ways of commencing this transaction:
| Type CEMT INQUIRE TCLASS (the minimum abbreviation is
| CEMT I TCL ). You get a display that lists the current
status.
| Type CEMT INQUIRE TCLASS ( CEMT I TCL ) followed by as
many of the other attributes as are necessary to limit the
range of information that you require. So, for example, if
you enter
cemt i tc p(value) , the resulting display will
show you the details of only those transaction classes
that have a purge threshold of the value indicated.
To change various attributes, use the CEMT SET TCLASS
command.

Displayed fields
ACtive( value)
displays the total number of transactions that are
currently active in a user-defined transaction class.
Maxactive( value)
displays the largest number of transactions in the
transaction class which are allowed to run concurrently.
The value can be in the range 0-999.
Note: You can reset this value by overtyping it with a
different value.
Purgethresh( value)
displays the limit at which the queuing transactions are
purged for the transaction class. It can have a value in
the range 0000000–1000000. Zero means that the
transactions are not purged. A nonzero number “n”
means that the first (n-1) transactions to arrive are
queued and the nth is purged.
Note: You can reset this value by overtyping it with a
different value.
Queued( value)
displays the total number of current tasks that are
suspended because the class maximum has been
reached.
TClass( value)
indicates that this panel relates to a TCLASS inquiry and
displays an 8-character transaction class name.
