Issue/Introduction

Can not connect to Server Application (eg: Datacom Server) from a workstation CCI/pc to CCITCP. The error message shows CCICONV FAILURE: CCI0053 TCP/IP WSA ECONN ABORTED

Resolution

The WSACONNABORTED message is indicating that the CCI connection between the desktop/server/pc and the mainframe has been severed somewhere in the network. Try the options listed below and if they do not resolve the issue, open a support ticket

• Ensure that the connection is being made to CCITCP (client to host) and not CCITCPGW (peer to peer)
• Verify if the mainframe CCITCP task is running at higher priority than the server application.
• Check if the "Disable Appl Timeout" or "Disable CCI Timeout Value" is enabled or disabled. If it is not checked off, try checking the box, apply the changes, and retry the action that caused the failure. If your CCI-PC configurator does not have the "Disable Appl Timeout Values" check box, you will need to get the latest version installed
• Similar symptoms have been seen when the internal CCI PING task terminates the session because it did not received back a valid response from its PINGs. In this situation, turning off the CCIPING function may do the trick. You can do this on the fly with modify command:
  
  F CCITCP, PING ,0
  
  If this seems to address the problem, permanently disable the PING process by updating your CCITCP proc with a //SYSIN DD statement that points to a RECFM=FB LRECL=80 file that contains the line and starts in column 1:
  PING 0
  
  
• Lastly, we've seen this encountered with PC's that have firewall software that will not allow the PING request through. So, first verify the CCI PING is turned off correctly, then look into any firewall software rules that may be in place. If none of the above resolves your connection problem, please turn on CCI traces and send them for review. Enable the CCI/pc trace from within the configurator "TRACE" Tab. Enable the mainframe CCITCP trace by entering the following command from THE CONSOLE:

F CCITCP,T,SYSPRINT *TO ACTIVATE TRACE
F CCITCP,NOTRACE *TO DEACTIVATE TRACE

* MAKE SURE SYSPRINT DD SPECIFIED IN CCITCP PROC....
