Changed system initialization parameters

Table 2 shows those system initialization parameters that have changed in some way.

Table 2. Changed system initialization parameters
Keywords Operands Explanation
EDSALIM {30M|number} The default value is now 30M
ENCRYPTION {STRONG |WEAK |MEDIUM} Specifies the cipher suites that CICS® uses for secure TCP/IP connections. For compatibility with previous releases, ENCRYPTION=NORMAL is accepted as an equivalent to ENCRYPTION=MEDIUM.

For more information, see the CICS System Definition Guide.

MAXJVMTCBS {5|number} specifies the maximum number of open TCBs that CICS can create in the pool of J8- and J9-mode TCBs for use by Java™ programs that run in a JVM (the JVM pool). Within this limit, there are no constraints on how many of the TCBs in the JVM pool are J9 TCBs, and how many are J8 TCBs.

For more information, see the CICS System Definition Guide.

STNTR, STNTRxx, SPCTR and SPCTRxx {level numbers} The SJ component (JVM domain) now has trace levels 29-32, that are reserved to indicate the JVM trace levels 0, 1, and 2, plus a user-definable JVM trace level. You are recommended to use only the SPCTRSJ system initialization parameter to activate JVM tracing, so that it is only activated for special transactions. Selecting tracing levels 29, 30, 31, 32 or ALL for standard tracing for the JVM domain (SJ) component (using the STNTR or STNTRSJ system initialization parameters) is not recommended, because JVM trace can produce a large amount of output.
