You might want to use a RACF® parameter library, but not have a member that is automatically processed during initialization. In that case, be aware that if you include a RACFPARM DD statement in your JCL, RACF assumes that you want a member processed automatically. If you do not specify a member on the PARM='OPT=xx' parameter, RACF attempts to process member IRROPT00 during initialization. If you do not have an IRROPT00 member, RACF issues a message. If you want to prevent RACF from automatically processing the IRROPT00 member in this situation, do not create one.
