IMS—Control IMS Security Processing

Valid on z/OS.

Use the IMS control option to set six different suboptions for IMS security processing. All entry methods are accepted.

When you use the IMS control option, the following requirements apply:

DBD validation, LCF message logging, and PSB validation are activated at the time of installation or when the region is recycled. If these values are changed, any region requiring the new settings must be recycled.
You must enter the LU6.1 subpool, Automatic Terminal Signon (ATS) default ACID, ATS logging, and APPL validation suboptions for them to be enabled.

This control option has the following format:

IMS([NO] {IMS61SUB} )
    [NO] {IMSATSDF}
    [NO] {IMSATSLG}
    [NO] {IMSDBDVL}
    [NO] {IMSLCFMG}
    [NO] {IMSPSBVL}

IMS61SUB

Specifies to use the LU6.1 subpool name for the ATS connection. The NO prefix disables this suboption and uses the LUNAME for the connection.

Default: NOIMS61SUB

IMSATSDF

Specifies to use the DEFACID facility for ATS. The NO prefix disables this suboption.

Default: NOIMSATSDF

IMSATSLG

Specifies that ATS signons are logged. The NO prefix disables this suboption.

Default: NOIMSATSLG

IMSDBDVL

Specifies that DBD validation is performed in IMS. The NO prefix stops DBD validation.

Default: IMSDBDVL

IMSLCFMG

Specifies that IMS transaction warning messages are displayed. The NO prefix disables IMS warning messages.

Default: IMSLCFMG

IMSPSBVL

Specifies that PSB validation occurs in IMS. The NO prefix stops PSB validation.

Default: IMSPSBVL

IMSAPPLL

Specifies that APPL validation occurs in IMS. The NO prefix disables APPL validation.

Default: NOIMSAPPLL

Example: Stop PSB Validation

This example stops PSB validation:

TSS MODIFY(IMS(NOIMSPSBVL))

Example: Use LU6.1 Subpool Name for the ATS Connection

This example allows the LU6.1 subpool name to be used for the ATS connection:

TSS MODIFY(IMS(IMS61SUB))
