Issue/Introduction

We have an issue with some transfers with XCOM from NonStop to Windows. Error is the following:

Some jobs fail in an random time with the error, but when you re-run the transfer, it completes normally.

Version of XCOM in Windows is 11.6.1709.0, version on NonStop is also 11.

 

Environment

Release : 11.1

Component : CA XCOM Data Transport for Hp NonStop

Resolution

Based on the traces received and reviewed, the following messages were received:

On Tandem:

"Txpi 226: Select timed out with no data available"

On Windows:

"XCOMN0780E TcpIp 506: Partner ended TCPIP connection unexpectedly."

In this case the connection was ended in 40 seconds per the Tandem trace. On the Windows side the transfer took a little longer to reply back to Tandem with the Header confirmation and could not since the connection had already ended.

It has been suggested that parameter TCP_TIMEOUT= be specified in the XCOMCNF file on Tandem. This should help with allowing the connection to be available a little longer in slow response time scenarios.

Also there are problems with the AV software on the Windows system that are causing problems. No details available on that.
