How can you determine which SCF static option values are being used in your CICS region or CA-Ideal batch job? This information can be obtained using the command @I$SCF DIS=OPTIONS. (Only users with CA-Ideal Administrator authority are authorized to execute this command.) This information can also be obtained by dumping module SC00OPTS in the CICS region or CA-Ideal batch job and evaluating a particular offset (see the section below on alternative methods).

* Refer to the CAIIPC Customization and Tuning Guide for detailed information on each of these options.

SCF Static Options and Offsets

The SCF static options are maintained in load module SC00OPTS. These options can only be changed by modifying, reassembling and relinking the static options block that is contained in SC00OPTS.

The options and their corresponding offsets in load module SC00OPTS follow below:


SCF Option	Offset in SC00OPTS
-------------------	----------------------------
  EDPFX		    1E
  PDPFX		    1C
  PNLIB		    B5
  PSSPFX		    75
  QCODE		      8
  SECRTY		    E7
  SESSID		    E8
  SCFPFX		    AA
  VLSLIB		    A2

Example 1: Obtaining the QCODE Option Value

Enter the following command on the CA-Ideal command line:
Note: "OFF=8" indicates the offset identifying the QCODE option. (Refer to the above table.)

@I$SCF DIS=OPTIONS OFF=8

Sample output:

=> @I$SCF DIS=OPTIONS OFF=8

-----------------------------------------------------------------------
SCF Debug                                                      Address=

00000028 +020  E2C3C640 C4C9E27E D6D7E3C9 D6D5E240  *SCF DIS=OPTIONS *

In the above sample output, the EBCDIC value for QCODE is "D7" which translates to character "P".

Example 2: Obtaining the SECRTY Option Value

Enter the following on the CA-Ideal command line:
Note: "OFF=E7" indicates the offset identifying the SECRTY option. (Refer to the above table.)

@I$SCF DIS=OPTIONS OFF=E7

Sample output:

=> @I$SCF DIS=OPTIONS OFF=E7

-----------------------------------------------------------------------
SCF Debug                                                      Address=
DIS= OPTIONS                  OFF= ______
USE= ____  ____  ____  ____  ____  ____  ____  ____
000000E7 +000  E8D6D5E4 40404040 40000000 00000000  *YONU     .......*
000000F7 +010  00000000 00000000 00000000 00000000  *................*
00000107 +020  00000000 00000000 00000000 00000000  *................*

In the above sample output, the EBCDIC value for SECRTY is "E8" which translates to character "Y". "Y" indicates that SECRTY is enabled. If SECRTY had been disabled, the EBCDIC value would have been "D5" or character "N".

Alternative Methods to Obtain SCF Static Option Values

SCF Static option values can also be obtained by dumping module SC00OPTS and evaluating the offsets listed above. The following methods can be used:

  1. From the CA-Ideal command line, enter:

    @I$SCF PGM=SC00OPTS OFF=nn

    where nn is the offset into SC00OPTS

    (CA-Ideal Administrator authority is required for this command.)

  2. From a native CICS environment that has CA-Datacom/CICS Services installed in it enter:

    DBUT M=SC00OPTS +nn

    where nn is the offset into SC00OPTS
