Issue/Introduction

Message on z/OS
XCOMM0780E Txpi 226: Select timed out with no data available
indicates that TCPIP is not responding back to XCOM in a timely matter and therefore the job ends. 

On z/VSE (VSEn)

XCOME0780E Txpi  226: Select timed out with no data available

 

Environment

Release: XCOM Data Transport-for z/OS
Component:

XCOM Data Transport for z/VSE

Cause

Indicates that TCPIP is not responding back to XCOM in a timely matter and therefore the job ends. 

Resolution

For z/OS

Parameter TCPRTIME in the CONFIG-Member used for the transfer specifies how long XCOM wait for an answer from the Transfer-Partner through the TCP/IP Network. 
Therefore check the value of this parameter and increase it if that problem happens often. This is not a XCOM Problem but a problem inside the TXP/IP Network.

Also check the TIMEOUT parameters

For z/VSE

Specifies in seconds the maximum time that XCOM Data Transport waits for a TCP/IP response during a TCP/IP receive function. 
Parameter TCPRTIME in the default Member used for the transfer specifies how long XCOM wait for an answer from the Transfer-Partner through the TCP/IP Network. 
Therefore check the value of this parameter and increase it if that problem happens often. This is not a XCOM Problem but a problem inside the TXP/IP Network.

Also check the TIMEOUT parameter.

Co not set to 0 (never timeout) as hangs may occur.

Additional Information

If increasing TIMEOUT or TCPRTIME does not resolve the problem, capture matching XCOM traces from both sides and optne a case with Broadcom Support and supply the traces and xcomlogs from both sides
