Specifying system initialization parameters for CICS web support

Specify these system initialization parameters to enable CICS web support.

Procedure

  1. Specify TCPIP=YES to activate CICS® TCP/IP services.
    The default setting is NO. YES must be specified to enable CICS web support.
  2. Use the LOCALCCSID system initialization parameter to specify the coded character set identifier for the local CICS region.
    CICS considers this code page as the default for application programs. The default is the EBCDIC code page 037. If you do not select alternative code page conversion options, CICS translates the data content of incoming HTTP requests into this code page before passing it to an application program. CICS assumes that the application has provided HTTP responses in this code page. For more information, see LOCALCCSID system initialization parameter.
  3. If you are planning to use CICS document template support, either to provide a static response to HTTP requests, or as part of an application-generated response, specify the default host code page for the document domain using the DOCCODEPAGE system initialization parameter. The default is the EBCDIC code page 037.
    For more information, see DOCCODEPAGE system initialization parameter.
  4. If you are planning to give web clients access to 3270 display applications, or if you are using the CICS business logic interface, specify suitable timeout periods using the WEBDELAY system initialization parameter.
    • The length of time, in minutes, after which a web task and its associated data are marked for deletion if no activity takes place on it. The default is 5 minutes.
    • The frequency, in minutes, with which the garbage collection transaction CWBG is run to delete the marked tasks and their data. The default is 60 minutes.
    WEBDELAY does not apply to CICS web support tasks that do not involve 3270 display applications or the CICS business logic interface. For more information, see WEBDELAY system initialization parameter.
  5. If you are want to use security with CICS web support, also set values for the following additional system initialization parameters:
    • CRLPROFILE
    • ENCRYPTION
    • KEYRING
    • MAXSSLTCBS
    • SSLCACHE
    For information on how to configure SSL, including specifying these system initialization parameters, see Configuring CICS to use SSL.
