CICS Sys62 - sys62_name (group_name)

Use this page to view and edit the Sys62 sys62, selected from the CICS Group group_name page. A Sys62 is a definition of an LU6.2 system connection.

The title bar gives details of the Sys62 you are editing and the resource group it belongs to.

Shows the name of this Sys62.


Specify a short description of the Sys62. Acceptable characters are A through Z, 0 through 9, $, @ and #.

LU Alias

Specify the parameter used to connect this definition to the LU6.2 protocol stack definition for this connection.

Mode Table

Specify the parameter that tells the LU6.2 protocol stack which Mode (or session characteristics) Table to use for this connection.

Partner Alias

Specify the parameter required to associate this definition with a peer server's definition within the LU6.2 protocol stack definitions.


Specify the SNA Application ID of the peer partner server for this connection.

Net Name

Specify the network name that identifies the remote system. The name can be up to eight characters in length. The name follows assembler language rules. It must start with an alphabetic character. The acceptable characters are: A-Z 0-9 $ @ and #. Lower-case characters are converted to upper case except when using the CREATE command.

Net Name is the APPLID of the remote system or region, unless you are defining an APPC or LUTYPE6.1 link to a VTAM generic resource group. If you are defining an LUTYPE6.1 link to a generic resource, Net Name must specify the generic resource name, not the APPLID of one of the group members. If you are defining an APPC link to a generic resource, Net Name can specify either the group’s generic resource name or the APPLID (member name) of one of the group members. However, if you specify a member name, and this CICS is not itself a member of a CICS Transaction Server for OS/390 generic resource, the connection must always be acquired by this CICS. For VTAM, the APPLID is the label of the remote ACF/VTAMÑ VBUILD TYPE=APPL statement. If you do not supply a Net Name, the CONNECTION name is used by default. You cannot have two or more APPC links with the same Net Name.

Session Max

Specify the maximum number of parallel sessions allowed to be active on this LU.


Specify the permanent four character transaction code to be attached to handle unsolicited input.


Specify the facility related priority to be used for work that is running with this as the primary facility.

In Service

Check this to enable this facilityto default to (or start initially as) being “in service”.

User ID

Specify the permanent user ID for this LU. Any work running against this facility will inherit the permissions of this user ID.


Specify the default language for user interfaces connected to this facility.

Session Name

Specify the name for the session.


Specify the level of attach-time user security required for the connection:

  • Identify - Incoming attach requests must specify a user identifier. IDENTIFY is used when the connecting system has a security manager; for example, if it is another CICS system.
  • Local - The authority of the user is taken to be that of the link itself, and you rely on link security alone to protect your resource. Local must be specified if the PROTOCOL attribute on the CONNECTION definition is LU6.1.
  • Mixed - Incoming attach requests may be using either or both IDENTIFY or PERSISTENT security types. The security type actually used depends on the incoming attach request.
  • Persistent - Incoming attach requests must specify a user identifier and a user password on the first attach request. Subsequent attach requests require only the user identifier. This should be used only between a PWS (programmable workstation, for example, an IBM Personal System/2) and CICS.
  • Verify - Incoming attach requests must specify a user identifier and a user password. Enter Verify when the connecting system has no security manager and hence cannot be trusted. Do not specify Verify for CICS-to-CICS communication, because CICS does not send passwords.
Oper ID

Specify the three-character operator ID associated with the permanent user ID - returned on ASSIGN OPID() command for transaction attached to this facility.

Oper Priority

Specify the operator-related priority for transactions running against this facility.

Resource Keys, all

Choose a setting to apply to all the resource keys:

  • On - enables all of the resource keys
  • Off - disables all of the resource keys
Resource Keys, 1 - 24

Check any of the boxes 1 through 24 to activate that resource key.
