Following are CICS ports settings in my TCPDATA:
Code:
; CICS ports                                   
  3080 TCP CICSAOR2            ; CICS Socket   
; 3080 TCP CICSTOR1  NOAUTOLOG ; CICS Socket     



And the CICS jobname is:
Code:
NP   JOBNAME  JobID    Owner    Prty Queue      C Max-RC      Pos  SAff  ASys S
     CICSAOR2 STC00073 STC        15 EXECUTION                     MVS1  MVS1   
:


I had set the CSKL txn like:
Code:
 APPLID       ===> CICSACB3             APPLID of CICS System                   
 TRANID       ===> CSKL                 Transaction Name of Listener           
 PORT         ===> 03080                Port Number of Listener                 
 AF           ===> INET                 Listener Address Family                 
 IMMEDIATE    ===> YES                  Immediate Startup   Yes|No             
 BACKLOG      ===> 040                  Backlog Value for Listener             
 NUMSOCK      ===> 100                  Number of Sockets in Listener           
 MINMSGL      ===> 004                  Minimum Message Length                 
 ACCTIME      ===> 030                  Timeout Value for ACCEPT               
 GIVTIME      ===> 010                  Timeout Value for GIVESOCKET           
 REATIME      ===> 300                  Timeout Value for READ                 
 TRANTRN      ===> YES                  Translate TRNID     Yes|No             
 TRANUSR      ===> YES                  Translate User Data Yes|No             
 SECEXIT      ===>                      Name of Security Exit                   
 WLM groups   ===> CICSGR1      ===>              ===>                           
:

I think it should be work,and the CSKL taks should be active.
but I encounted the following:
Code:
EZY1261I 02/03/10 17:54:43 EZACIC03 ATTACH SUCCESSFUL, TCB ADDRESS=0069F360 TERM=     TRAN=CSKL TASK=0000070
EZY1291I 02/03/10 17:54:44 LISTENER TRANSACTION= CSKL TASKID= 0000070L ACCEPTING REQUESTS VIA PORT   3080 

EZY1261I 02/03/10 17:55:18 EZACIC03 ATTACH SUCCESSFUL, TCB ADDRESS=0069F1C8 TERM=     TRAN=CSKL TASK=0000072
EZY1295E 02/03/10 17:55:18 BIND CALL FAILURE TRANSACTION= CSKL TASKID= 0000072L ERRNO=       48             
EZY1278I 02/03/10 17:55:18 EZACIC03 DETACH SUCCESSFUL TCB ADDRESS=0069F1C8 TRAN=CSKL TASK=0000072           
:

Who can tell me what's wrong with the settings?
Thanks in advance.

Hello,

Maybe:
Quote:
An ERRNO=48 could indicate that the port is not reserved in hlq.TCPIP.PROFILE.

Netstat is a TSO (or Unix System Services) command to provide information about the state of TCP/IP. A batch job to do it is:
Code:
//TMP   EXEC  PGM=IKJEFT01,REGION=0M,
//           DYNAMNBR=200
//*
//SYSPROC  DD  DSN=SYS1.SBPXEXEC,DISP=SHR
//*
//SYSTSPRT DD  SYSOUT=*
//STDOUT   DD SYSOUT=*
//*
//SYSTSIN  DD  *
  netstat conn
/*
Note that SYS1.SBPXEXEC is the default name and could have been changed at your site (although the low level probably is still SBPXEXEC).

After you run the job, look at the output for your region and verify that there's a listener on port 3080. if not, you've got a TCP/IP set up issue that needs your site support group to fix.

You can also use console command D TCPIP,,NETSTAT,CONN to get the same information.

Code:
MVS TCP/IP NETSTAT CS V1R6       TCPIP Name: TCPIP           18:35:40 
User Id  Conn     Local Socket           Foreign Socket         State 
-------  ----     ------------           --------------         ----- 
CICSACB3 00000043 0.0.0.0..3082          *..*                   UDP


Here goes the output.How can read the spool log.
I can not find the 3080 port.Can I use 3082 for CICS port instead?

by the way,where did all these infor set.

Thank you very much.

Interpretation: CICSACB3 is listening for all IP addresses (that's what the 0.0.0.0 means) on port 3082 as a UDP connection. All remote connections are allowed, although I usually see 0.0.0.0..0 instead of *..* (something must have changed from 1.6 to 1.8 of z/OS). The 0.0.0.0 would be significant if you're using multiple IP addresses in the LPAR (we were doing so when running Lotus Notes on z/OS, and we had to restrict listeners to only certain IP addresses or Lotus and TCIP/IP would have issues).

Try port 3082 since that's what is listed -- I don't know what's happening to port 3080 but if it'll work on 3082, go for it! icon_smile.gif

UDP connection?
Is this something different from TCPIP connection?

Is this cause the different TCPIPServices settings?

Would you please explian it in detail?
Thanks for your time on this.

User Datagram Protocol is a stateless transmission protocol -- meaning that packets can disappear, show up out of sequence, or show up with errors because there's no error checking. Tranmission Control Protocol, on the other hand, provides error-checked, ordered packets of data to the application. Both are used for different applications (UDP is used for Domain Name Services and Voice Over IP, for example), depending upon their needs.

Both UDP and TCP are TCP/IP connections; they just have different purposes and processing. I'm not familiar enough with CSKL to know if it can handle out-of-sequence or missing data -- if not, then UDP is not the right choice of protocol.

I updated CICS port number to 3082 in the TCPIP.PROFILE

and changed the CSKL port definition to 3082 also.

but when start the CICS region using EZAO START,
I got the
Code:
EZY1295E 02/03/10 17:55:18 BIND CALL FAILURE

again,I am totaly confused.

Shall I also update the port number defined in TCPIPServices?

There must be some steps I omitted,would you please
help telling me?Thanks a lot for your time.

Best Regards
David

I see that the portnumber is prefixed with a zero :

PORT ===> 03080 Port Number of Listener

Maybe that could be the culprit.

Peter, hopefully not since ports can go up to 65535; the leading zero may be numeric justification. It would be worth trying to take the leading zero off, though, to see if the results are different.

tiger_wen, I agree with Enrico -- it is time to contact your site support group and get network assistance. They have the tools to diagnose the problem and trace what's happening.

BIND = 48 = EADDRINUSE
The address is in a timed wait because a LINGER delay from a previous close or another process is using the address.

The port are in use, or you need set the socket with REUSE OPTION.

Thanks for your reply.
Would you please tell how to set the REUSE OPTION for the socket?

David...
After CALL 'EZASOKET' USING WRK-SOCKET , you need do this call before BIND call:

MOVE 4 TO WRK-OPTNAME
WRK-OPTLEN.
MOVE 1 TO WRK-OPTVAL.

CALL 'EZASOKET' USING WRK-SETSOCKOPT WRK-SOCKID
WRK-OPTNAME WRK-OPTVAL WRK-OPTLEN
WRK-ERRNO WRK-RETCODE.


OPTNAME equal 4 means REUSEADDR.

I happened to find the following infor form red book(GG24-4026-00).

Quote:
If the CSKL transaction abends with a code of BIND when you try to use CSKE to
enable the interface, the jobname for your CICS region does not match the name
specified for this port in tcpip.PROFILE.TCPIP. In other words, you are trying to
use a port that has been reserved for another application. Messages similar to


It is seems that the 3080 port is reserved by other pgm.I will try to updated the port definition in PROFILE.

Thanks everyone's great help on this,thx a lot.[/code]
