You can use intensive mode error recording to record and signal each temporary error over a link and its cause to VTAM®.

When you receive many temporary errors for a line, but not enough to create a permanent error, you can use intensive mode recording to find the cause of the error.

To start NCP intensive mode recording, issue the MODIFY IMR command.

The MODIFY IMR command causes the owning system services control point (SSCP) to send a request to the NCP. The NCP then builds and sends RECMS RUs to the SSCP each time an error occurs. The SSCP writes these error records on the LOGREC file. It can also optionally pass them to a user-defined communication network management (CNM) application program, such as the NetView® program. See MODIFY IMR command in z/OS Communications Server: SNA Operation for more information.
