| Parameter | Specify . . . | Minimum | Maximum | Default |
|---|---|---|---|---|
| NQCID | the maximum number of active command IDs per user. | 1 | 65535 | 20 |
The table of sequential commands contains the control blocks for sequential read operations. Each operation is identified by a command ID (CID). NQCID defines the total number of CIDs allowed per user, and therefore the maximum number of table elements the user has available at any point in time.
Note:
The NQCID value specified does not ensure that all users have the
specified count of CIDs available at all times. The actual number of CIDs
available to a single user depends on the totals of table elements available
and sequential operations active at a given time.
The maximum number of parallel sequential processes per user is 30.
ADARUN PROG=ADANUC,NQCID=25,NU=200,LQ=3000
Since one element in the sequential command table occupies approximately 100 bytes (varies depending on the command type; see the description of the LQ parameter), NQCID=25 limits each user to approximately 2500 bytes of the table.
You can override this parameter setting for an individual user by specifying a different value in the Adabas control block for an OP command. See the discussion of the OP command in the Adabas Command Reference documentation.
