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.

This control option has the following format:

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

IMS61SUB

Specifies that the LU6.1 subpool name be used for the Automatic Terminal Signon (ATS) connection. The NO prefix disables this suboption and the LUNAME is used for the connection.

Default: NOIMS61SUB

IMSATSDF

Specifies that the facility DEFACID be used for the Automatic Terminal Signon. The NO prefix disables this suboption.

Default: NOIMSATSLG

IMSATSLG

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

Default: IMSDBDVL

IMSDBDVL

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

Default: IMSNOIMSATSDF

IMSLCFMG

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

Default: LCFMG

IMSPSBVL

Specifies that PSB validation will occur in IMS; the default. The NO prefix stops PSB validation.

Default: IMSPSBVL

Be aware of the following when using the IMS control option.

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

Examples: IMS control option

This example turns off PSB validation.

TSS MODIFY(IMS(NOIMSPSBVL))

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