You operate the broker using the z/OS® START, STOP, and MODIFY commands.
However, you are likely to need to issue commands with mixed case, because integration server names are often in mixed case. You can issue commands with mixed case on the z/OS console, using the REXX CONSOLE interface, with products like SDSF V2.10 and higher, and NetView. Releases of SDSF before V2.10, and the TSO CONSOLE facility, do not support passing mixed case data.
//MI01CMD JOB MSGCLASS=H
// COMMAND 'f MQP1BRK,ct t=yes,e='default',l=debug,f='lowmfl''
//STEP1 EXEC PGM=IEFBR14
If your product for issuing console commands supports mixed case input, you might need to take special actions to use mixed case. For example in SDSF on OS/390® V2.10 and above, you can enter mixed case keyword values by typing /, pressing ENTER, and entering the command in the popup window. If you enter / followed by the command, the command is translated to uppercase. In NetView, prefix the command with NETVASIS to get lowercase support.
