The OPT parameters allow the installation to change many system resources manager (SRM) constants. The following list categorizes the options as special including, for example, abnormal termination or whether non-enclave transaction work of queue servers and enclave servers is to be managed or not, adjusting options for constants, or options for special assist processors.
The OPT contains several categories of information. The keywords
need not be grouped by category and can appear in any order. The system
ignores both repetition of a keyword and the use of keywords that
were used in prior releases and are no longer supported.
