NEWSIT

The NEWSIT system initialization parameter specifies whether CICS® is to load the specified SIT, and enforce the use of all system initialization parameters, modified by any system initialization parameters provided by PARM, SYSIN, or the system console, even in a warm start.

Defining NEWSIT

You can define the NEWSIT system initialization parameter in the following ways:
  • In the PARM parameter of the EXEC PGM=DFHSIP statement.
  • In the SYSIN data set of the CICS startup job stream.
  • Through the system console.
You cannot define the NEWSIT system initialization parameter in the DFHSIT macro.

Values for NEWSIT

Valid values for the NEWSIT system initialization parameter are as follows:

NEWSIT={YES|NO}
Enforcing the use of system initialization parameters in this way overrides any parameters that may have been stored in a warm keypoint at shutdown.
However, there are some exceptions. The following system initialization parameters are always ignored in a warm start, even if they are supplied by PARM, SYSIN, or the console:
  • CSDACC
  • CSDBUFND
  • CSDBUFNI
  • CSDDISP
  • CSDDSN
  • CSDFRLOG
  • CSDINTEG
  • CSDJID
  • CSDLSRNO
  • CSDRECOV
  • CSDRLS
  • CSDSTRNO
  • FCT
  • GRPLIST

In a warm restart, CICS uses the installed resource definitions saved in the CICS global catalog at warm shutdown, and therefore the CSD, FCT, and GRPLIST parameters are ignored. (At CICS startup, you can only modify installed resource definitions, including file control table entries, or change to a new FCT, by performing a cold start of CICS with START=COLD.)

For more information about the use of the NEWSIT system initialization parameter, see Controlling start and restart.

Restriction: You can specify the NEWSIT system initialization parameter in PARM, SYSIN, or CONSOLE only.
