Parameter descriptions
- (psid-number)
- Identifier of the page set. This is required.
In WebSphere MQ for z/OS a one-to-one relationship exists between page sets and the VSAM data sets used to store the pages. The identifier consists of a number in the range 00 through 99. It is used to generate a ddname, which references the VSAM ESDS data set, in the range CSQP0000 through CSQP0099.
The identifier must not be the same as any other page set identifier currently defined on this queue manager.
- BUFFPOOL(integer)
- The buffer pool number (in the range zero through 15). This is optional. The default is zero.
