mmm parameter set in received message assembling UOC is invalid. connection name=aa...aa UOC return code=bb...bb error code=cc...cc UOC parameter=dd...dd

mmm: NET identifier

aa...aa: Connection name

bb...bb: User exit routine return code

cc...cc: Failure code

0001: Invalid user exit routine return code

0002: Invalid size for remaining segments

0003: Invalid size for assembled segments

0004: Invalid value for the timer that monitors subsequent segments

dd...dd: User exit routine specified value (value of the parameter shown by the failure code)

S: Releases the connection and instructs the user to release the connection forcibly. The connection release will be completed when the system receives the user's response to the forced connection release instruction.

Discards any received message that is assembling segments.

O: Contact the OpenTP1 administrator.

Countermeasure: In the case of invalid size for remaining segments, the following is a probable cause.

• The size for remaining segments is zero or negative, or the total of it and the size for assembled segments has exceeded the length of the receive buffer.

Review the processing of the user exit routine function, the format of the send message in the other system, or the size of the receive buffer.

Restart the system if the user exit routine function or buffer size is defined again.
