HEADER statements
The HEADER statement is speci®c to the Builder, and is not a CICSPlex SM statement. It is produced by the Reporter, and is needed by the Builder to create unique transaction group names.
The Reporter generates temporary transaction group names (for example, CW.00000001 and TS.00000001) while it is running, and stores these names in the output data set for that run. However, the Builder can take several Reporter data sets as input, and may therefore get the same transaction group name from different input data sets (describing different affinity transaction groups).
To ensure that the transaction group names are unique, the input transaction group names are quali®ed by the input data set name. To do this, when the Builder reads a HEADER statement (the ®rst line of an input data set), it obtains the data set name from MVS. The HEADER statement is vital because without it the Builder cannot detect the change from one input data set to another.
If you omit a HEADER statement, the Builder may generate error messages or add transactions to the wrong group, and give incorrect line numbers in the error report and an incomplete report of data sets processed.
Output from the Builder
The Builder outputs a ®le containing a set of de®nitions for combined affinity transaction groups, and a report listing the combinations that occurred.
Combined affinity transaction group de®nitions
Before each de®nition of a combined group in the output ®le, the Builder adds a
The name of each combined affinity transaction group is derived from the alphanumerically ®rst transaction identi®er in the combined group. For example, if ABCD was ®rst, the transaction group name would be ABCDGRP.
Note: For CICSPlex SM, the name of each combined affinity transaction group must be unique.
For example, Figure 11 on page 59 shows the set of combined de®nitions that correspond to the basic de®nitions in Figure 9 on page 47, assuming that a MATCH ®lter of LUNAME, a STATE of ACTIVE, and a CONTEXT of CICPLEX1 was speci®ed on the PARM statement.
