APPMODAL

z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures
GC27-3667-00

Use APPMODAL to display all information about a particular logon mode for a conversation between an application and a partner LU. APPMODAL will process the LU entries searching for all LU entries that match the specified partner LU name and the optional partner LU NetID. If LU entries are found, the chain of modes is searched for a match to the specified logon mode name. If a matching logon mode is found, APPMODAL determines the settings for:
  • Current® session limits(x,y,z), where:
     x - Session limit
     y - Minimum number of contention winner sessions for local LU
     z - Minimum number of contention winner sessions for remote LU
  • Current session count(x,y,z), where:
     x - Active session count
     y - Active contention winners at local LU
     z - Active contention winners at remote LU
  • Pending session counts(x,y,z), where:
     x - Count of pending sessions
     y - Count of pending contention winners
     z - Count of pending contention losers
  • Pending session termination counts(x,y,z), where:
     x - Pending termination contention winners + losers
     y - Pending termination contention winners
     z - Pending termination contention losers
  • Defined session limits(x,y,z), where:
     x - Defined session limit
     y - Defined minimum number of contention winner sessions for local LU
     z - Defined minimum number of contention winner sessions for remote LU
APPMODAL displays:
  • Active conversations between the two applications on the logon mode by running the chain of RABs
  • Waiting requests off the logon mode (requests for conversations that have not been serviced)
  • Free sessions on the logon mode (SABs that represent sessions that are not currently assigned to a conversation)
  • Pending active sessions on the logon mode (SABs that represent sessions that are in the process of being activated on the logon mode)
APPMODAL formats and displays the APPCB, COPR, LME (selected fields), RAB, and SAB control blocks.

Operands

APPC application name
The APPC application name should be 1–8 alphanumeric characters. If it contains fewer than 8 characters, it is padded on the right with blanks.

The APPC application name is required.

Partner LU name
The partner LU name should be 1–8 alphanumeric characters. If it contains fewer than 8 characters, it is padded on the right with blanks.

The partner LU name is required.

Partner LU NetID
The partner LU NetID should be 1–8 alphanumeric characters. If it contains fewer than 8 characters, it is padded on the right with blanks.
Logon mode name
The logon mode name should be 1–8 alphanumeric characters. If it contains fewer than 8 characters, it is padded on the right with blanks.

The logon mode name is required.
