When to use the NCP dump z/OS Communications Server: SNA Diagnosis Vol 1, Techniques and Procedures GC27-3667-00 |
|
A dump of the NCP should be taken whenever the NCP abnormally terminates or when an error is suspected in the NCP. It may be possible to determine that a problem exists in the NCP by using the VTAM® I/O trace to determine what PIUs are being sent to and received from the communication controller and by using the NCP line trace to determine what is happening on the lines between the communication controller and the link-attached logical unit. |
