Problem

PEL922 with PeSIT code 3-313

Error appears at the end of the successful transfers, not affecting the transfer itself

Resolution

The error (Connection closed due to inactivity) is most probably related to the server closing the session before the requester.

Usually, the requester has (must have) a lower disconnect parameter value than the server, when those values are close each other, it may lead to the server closing the session just after sending the ACK TransEnd.

It can also be due to an heavy load on the requester side making the monitor a bit slower to deal with the end of PeSIT session and session disconnect.

On Interpel MVS, it is about the GENTER parameter SESSION

It can be set to zero to avoid those errors, it will make Interpel to close the session as sonn as the transfer is completed (so, most probably, before the server)

* SESSON={n|0}
Délai en minutes avant la libération d'une connexion inactive.
0 - libération immédiate.
255 - pas de libération.

Note: For Transfer CFT, it is parameters DISCTD and DISCTS from the CFTPROT macro.
