Important RRS CTRACE information

RRS strongly suggests that you have the following CTRACE options set at all times. This ensures you have the most trace information available in the RRS dumps. Create a CTIRRSxx parmlib member that contains the following options:

TRACEOPTS                                                                 
  ON                                                                      
  BUFSIZE(500M)                                                           
  OPTIONS('EVENTS(URSERVS,LOGGING,CONTEXT,EXITS,STATECHG,RRSAPI,RESTART)')

To ensure that these CTRACE settings are always active:

• Issue the S RRS command, specifying the CTIRRSxx parmlib member.
• Update the RRS procedure with the CTMEM value to ensure that RRS CTRACE is running on each startup.

If RRS is already started, to set these options, issue the following z/OS® command:

TRACE CT,ON,COMP=SYSRRS,PARM=CTIRRSxx

RRS CTRACE in a sysplex cascaded transaction environment and problem determination mode: If you are running a sysplex cascaded transaction environment and are in problem determination mode, use the external writer to trace more data. In addition, update the RRS trace to use the following option:

OPTIONS(‘EVENTS(ALL)’)

You are in problem determination mode when you are collecting documentation for a recurring problem, such has a transaction hang or delay.
