Note:
The NUCID parameter replaces the earlier parameters PLXID and
SMPID.
| Parameter | Specify . . . | Possible Values | Default |
|---|---|---|---|
| NUCID | the ID for a nucleus in an Adabas cluster. | 0-65000 | 0 |
NUCID identifies an Adabas cluster nucleus. The cluster may span operating system images under Adabas Cluster Services, or it may be confined to a single operating system image under Adabas Parallel Services. A value greater than 0 (the default) identifies this nucleus as an Adabas cluster nucleus.
| Value | Meaning |
|---|---|
| 0 | The default setting. This is not an Adabas cluster nucleus. For ADADBS OPERCOM and AOS, the NUCID=0 command option means "global", indicating that the command applies to all nuclei in the cluster. |
| 1-65000 | This is an Adabas cluster nucleus. A nonzero value automatically sets the parameter READONLY=NO; MODE=MULTI should also be specified. Values need not be specified contiguously. This value must be unique among all Adabas database IDs, NUCIDs, Natural buffer pool IDs, etc. Entire Net-Work target IDs (suggested range 65482-65535), and internal target IDs used by Adabas Cluster Services (restricted range 65001-65481) are assigned outside of the range of possible values for NUCID. For ADADBS OPERCOM and AOS, a nonzero value for the NUCID command option indicates that the command applies just to the cluster nucleus specified. |
Note:
For ADADBS OPERCOM and AOS, a zero value for the NUCID command option
indicates that the command applies to all nuclei in the cluster ("global"). A
nonzero value for the NUCID command option indicates that the command applies
only to the cluster nucleus specified.
Each nucleus being run must have its own Work dataset.
All nuclei in a cluster must be run against the same database.
Software AG strongly recommends that you run utilities or user applications against a nucleus in the local OS/390 image. Although a remote open nucleus may be used, performance degradation due to network overhead is likely.
If ADACOM is active for a database and you start a nucleus with NUCID=0 for that database, any utilities or user applications sending commands to that nucleus receive a response code 148.
Start an Adabas cluster session with the specified cluster nuclei:
ADARUN PROG=ADANUC,NUCID=1, ...
