Attribute Semantics

TA_DMSNASTACK: string[1..30]

The name of this T_DM_SNASTACK entry. TA_DMSNASTACK is an identifier unique within the scope of T_DM_SNASTACK entry names in the Domains configuration.

TA_DMSNACRM: string[1..30]

Identifies the T_DM_SNACRM entry of the SNA CRM in which this SNA protocol stack definition is used.

TA_DMSTACKTYPE: string[1..30]

Identifies the protocol stack to be used.

TA_DMLUNAME: string[1..8]

Specifies the LU name to be used on sessions established using this stack definition.

TA_DMTPNAME: string[1..8]

Specifies the TP name associated with the SNA stack. A value of "*" means accept any TP name.

TA_DMSTACKPARMS: string[1..128]

Provides protocol stack specific parameters.

TA_STATE:

GET: "{VALid}"

A GET operation retrieves configuration information for the T_DM_SNASTACK object. The following state indicates the meaning of a TA_STATE attribute value returned in response to a GET request. States not listed are not returned.

"VALid"

The object exists.

SET: "{NEW | INValid}"

A SET operation updates configuration information for the selected T_DM_SNASTACK object. The following states indicate the meaning of TA_STATE in a SET request. States not listed may not be set.

"NEW"	A new object is created. This state change is allowed in the state "INValid" and results in the state "VALid".
unset	Modify an existing object. This combination is not allowed in the state "INValid".
"INValid"	The object is deleted. This state change is allowed in the state "VALid" and results in the state "INValid".

Limitations

Deleting or updating an instance of this class is not permitted if the instance of the class references a T_DM_SNACRM object which references a local domain access point for which the Domain gateway administration (GWADM) server is active.

On SET operations that add or update an instance of this class, the SNA CRM name specified in the TA_DMSNACRM attribute must exist in the T_DM_SNACRM class. If the name does not exist, a "not defined" error is returned for the TA_DMSNACRM attribute, and the operation fails.
