If several SLSs are installed on the partitions, the following cards should be coded on the VANTAGE STC:
//SLSCNTL DD DISP=SHR,DSN=your.primary.CDS
//SLSCNTL2 DD DISP=SHR,DSN=your.secondary.CDS
//SLSCNTL2 DD DISP=SHR,DSN=your.NNN.CDS
//SLSSTBY DD DISP=SHR,DSN=Syour.standby.CDS
The most recently updated control data set (CDS) specified in the SLSCNTL, SLSCNTL2, ....or SLSSTBY DD names are now selected for the BATCHAPI processing.
