Info

92 CICS Transaction Gateway V5 In our example, we were using the TCP/IP stack TCPIPMVS on our z/OS system. However, because we specified ALL for the IPADDRESS of our TCPIPSERVICE, our CICS region is listening on both TCP/IP stacks. To display the TCP/IP sockets in use by CICS, you can use the TSO NETSTAT command as shown in Example 5-6. This will give you similar information that you got from the client side. The output shows our CICS region listening on port 8018. Example 5-6 MVS NETSTAT EZZ2350I MVS TCP/IP NETSTAT CS V1R2 TCPIP NAME: TCPIPMVS 18:25:59 EZZ2585I User Id Conn Local Socket Foreign Socket State EZZ2586I ------- ---- ------------ -------------- ----- EZZ2587I SCSCPJA1 000085F2 0.0.0.0..8011 0.0.0.0..0 Listen EZZ2587I SCSCPJA1 000085F4 0.0.0.0..8018 0.0.0.0..0 Listen EZZ2587I SCSCPJA1 000085F0 0.0.0.0..8010 0.0.0.0..0 Listen To display the TCP/IP sockets in use by CICS on the TCP/IP stack TCPIPOE, you can use the OMVS command netstat /a as shown in Example 5-7. The output shows our CICS region listening on port 8018 on the TCPIPOE stack. Example 5-7 OMVS netstat MVS TCP/IP onetstat CS V1R2 TCPIP Name: TCPIPOE 14:48:01 User Id Conn Local Socket Foreign Socket State ------- ---- ------------ -------------- ----- PMAPOE1 00000037 0.0.0.0..111 0.0.0.0..0 Listen SCSCPJA1 00000B09 0.0.0.0..8078 0.0.0.0..0 Listen SCSCPJA1 00000D90 0.0.0.0..8018 0.0.0.0..0 Listen SCSCPJA1 00000B03 0.0.0.0..8010 0.0.0.0..0 Listen Traceroute If the ping command fails to reach a host, then the tracert command can be used to discover more about the problem. Like ping, tracert tests connectivity between two network hosts; however, tracert lists each router in the network between the machine running the command and the destination host. Sometimes an inability to contact a host is due to one of these routers not forwarding IP traffic, so tracert can be used to discover which router is preventing a connection to a remote host. In Example 5-8 on page 93 we traced the route from our Windows workstation to our z/OS system using the command tracert wtsc66.itso.ibm.com from a Windows command prompt.
Example 5-8 tracert command C:\>tracert wtsc66.itso.ibm.com Tracing route to wtsc66.itso.ibm.com [9.12.6.6] over a maximum of 30 hops: 1
