Issue/Introduction

A TCP/IP communications port controlled by SOLVE:CPT presented slowness. Cust checked with

IBM on TCP/IP but the cause was not identified.  It was shown delay on some moments

of connectivity controlled by SOLVE:CPT.

 

Also a gap (drop) was noticed on the connections using the SOLVE:CPT LISTEN port.  Following

each gap (drop)--that occurred every 4 hours--work resumed normally. 

Environment

Mobile application.

Cause

-

Resolution

Following the MIPS addition to the environment and creation of a new CICS the problem went away. 

-

On the gap (drop):  It was discovered that the problem was on the server that calls CICS.

-

Every 4 hours the switch 're-learns' the ARP.  Situation was corrected.

Additional Information
