Re: RES: Installing/Updating SVC
Lindy, The main risk is in the fact that it is an undocumented feature. This feature has a lot of limitations. You cannot specify the SVC type (1,2,3/4,6) and you cannot set the SVC flags, such as: APF, Locks required, Non-preemptive and etc. Philippe Leite z/OS Systems Programmer Portugal On Fri, 23 Nov 2007 16:15:51 +0100, Lindy Mayfield <[EMAIL PROTECTED]> wrote: >Risk? > >Or do you mean that anything outside of an IPL is potentially risky? > -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

SVC Screening and TCBUSER
Hi Listers, I'm writing a SVC screening program to monitor some SVCs. I'm executing CPOOL BUILD in the main program and I want to pass the CPID to Screen routine. The Screen routine will execute CPOOL GET/FREE based on the CPID passed by the main program. My question is: Is it safe to pass the CPID from the main program to the Screen routine through the TCBUSER ? Do I have a better alternative ?
