ddnames of general data sets

The following list shows the data definition names, also known as ddnames, for required and optional data sets.

The ddnames for the required data sets are:

INPUTDD

The data set that contains the Db2 trace data to be used as input for OMEGAMON for Db2 Performance Expert reports. You must specify this fully qualified data set name.

If your Db2 trace data is provided in SMF log streams, specify the log stream name. You can also specify an additional range of dates if required.

In the following example, all Db2 traces that are available in z/OS log stream "IFASMF.SYSA.DB2" are processed by the batch reporter. The FROM and TO arguments can be used to control the date range.

 
//INPUTDD  DD DSN=IFASMF.SYSA.Db2,                            
//         DCB=(RECFM=VB,BLKSIZE=32760,LRECL=32756),          
//         SUBSYS=(LOGR,IFASEXIT,'FROM=OLDEST,TO=YOUNGEST')
