Session initiation states
A session state can be classified into one of the following
three groups:
- Q (Queued)
- If the session state is preceded by A-, the session is traversing the APPN portion of the network. The session is considered queued when the session request has been received at a node performing only APPN functions for this session.
- For all other states, the session is considered queued under the
following circumstances:
- A session request has been received, but session establishment has not located the resources required for the session.
- The resources required for the session have been located; however, the resources are temporarily unavailable for sessions. Further session establishment procedures have been suspended until the resource is available. The session is in a reallocation-pending state.
- P/A (Pending Active)
- A session is considered to be pending active when both resources required for session setup have been successfully located and are available for sessions. Session establishment proceeds.
- ACT (Active)
A session is considered active (ACT) when all session start signals have been received, and a session has been successfully established.
The following table lists possible session states.
Note: If the session state is preceded by A-, the
session is traversing the APPN portion of the network.
| Session state | Status | Meaning |
|---|---|---|
| A-PCOS | Q | Pending COS reply. |
| A-PCRYPT | Q | Pending cryptographic keys. |
| A-PDS | Q | VTAM® has an APPN locate chain for the session. A search might be in progress or completed, but the session is not fully active yet. To determine the complete status of the session, use the SID and LU names from the message to find the LUs and session in this and other hosts. |
| A-PNCOSM | Q | Pending entry COS mapping. |
| A-PRSCV | Q | Pending RSCV reply. |
| A-PSACF | Q | Pending subarea chain flow. |
| A-PSAR | Q | Pending Subarea reply. |
| A-PTGVS | Q | Pending TG reply. |
| A-PXCOSM | Q | Pending exit COS mapping. |
| A-QUEUE | Q | This LU-LU session is queued. One of the LUs is at its session limit or is not available. If this VTAM is functioning as an APPN network node server and is not doing any subarea routing, this state is the only queued state that is displayed. If this VTAM does subarea routing, in either a pure subarea or mixed APPN/subarea network, one of the other queued session states listed in this table will be displayed. |
| A-RESET | Q | The session is reset. |
| A-TERM | P/A | The session is pending termination. |
| ACTIV | ACT | The session is active. A session has been successfully established. |
| ADIALIP | P/A | Dial in progress for APPN LU. |
| CDPRIP | Q | CDINIT pending cross-domain routing completion. Another request is pending for the specified LU, and this session will wait for routing to complete. |
| DDIALIP | Q | Dial in progress for DLU. A session will stay in DDIALIP until the DIAL START process completes. This process includes completing the connection and activating the PU and its subordinate resources. The length of time a session stays in DDIALIP is dependent upon the network configuration. |
