IOCDS= parameter

The IOCDSRES parameter identifies the resident IOCDS ID that BBXS will use during initialization.

It has values Ax or Bx, where x is a number that may be as high as 7, depending upon your processor. The number refers to the IOCDS within the Processor Controller File. You must obtain and use the correct IOCDS ID. There may be separate IOCDSs for each LPAR in your system.

Warning

Note

BMC recommends that you contact the person responsible for IOCDS generations at your site to obtain the current IOCDS ID and notify that person that the IOCDSRES parameter in BBXSINIT must be kept up to date with any changes made to the IOCDS.

BMC also recommends that you define the BBXSINIT program, by using the IOCDSRES parameter, as an automatically started procedure so that you can provide the location of the IOCDS data.

You can make z/OS automatically start BBXS initialization in an z/OS system running under VM by defining the sample statement (as in the following figure) within a COMMNDxx member of SYS1.PARMLIB.

COM='S BBXSINIT,IOCDS=Ax'

This statement assumes that you renamed the sample @BBXINIT procedure to BBXSINIT when you copied @BBXINIT from the BBSAMP data set to your SYS1.PROCLIB data set during customization.

Error
Warning

If the IOCDSRES parameter is not supplied when BBXS is initialized, BBXS issues a WTOR message, BBX017A, prompting you for the IOCDS data set ID. It is easy to miss this message and, if no response is made, BBXS continues without the I/O configuration data.
