    Hi there,

    Sorry you're having problems with CICS Explorer. Are you using a CMCI connection? CMCI uses http like a web browser; when you try to display a transaction definition, Explorer makes an http request and expects a reply. If that reply doesn't come within a minute or so you can get a time-out. Or if you have a bad proxy set perhaps the failure could be instantaneous. It's difficult to say too much from the log snippet you posted.

    Could you collect some trace data and attach it for us? From the Explorer menu, choose trace, collect service data. You can email it to me - dave.nice@uk.ibm.com if you would rather not attach it here. That will allow us to see in a bit more detail whether the server is just responding slowly and that one call has gone over the limit.

    Just to clarify a bit, could you answer:
    1) Does this happen consistently just when you do one thing in the GUI?
    2) Does it always happen when you do the one thing in the GUI?
    3) Is the GUI generally slow to respond?

    Thanks in advance!

    Dave

    Hi,

    Thanks for your response.

    The trace shows that we make the HTTP request which then times out after a minute. This is equivalent to opening a web browser, trying to contact the site, receiving no response and getting a time-out error.

    Do you have any problems with similar function via the WUI, if you have one setup?

    Is there anything in the CICS logs?

    After you've started seeing this problem, do other operations that were performing quickly slow down?

    My thinking currently is that the problem is server side, so I'll have a chat to someone here and see if they've got any more ideas on debugging.

    Thanks in advance,

    Dave

    Do you have firewalls between you and the host?

    No firewalls between, because mq explorer works fine

    Dave the connection works fine, but now when Working with resources and select right-click all the options are disables, attaching a example.
    Is necesary Setting up a JVM server in CICS?
    I can´t purge, force purge or kill in tasks, all this options are disables

    Hey,

    The reason a number of the options are disabled (mainly the read/write ones) is that you're on an SM Data connection which is read-only. The newer CMCI connection type supports read and write (and other things like sorting columns if you're on 4.2!)

    I still don't have a better answer about the interface slowness - I had wondered (like kevmeist) about a firewall, but given that most of the data comes through that seems unlikely. I don't think it can be a permissions issue because I don't think that would cause slow response.

    Good to see you've got Explorer going, do keep us posted with your progress.

    Dave hi.

    I have two versions of cics explore, on version 1.0.1.2 the CMCI works fine but on version 1.1.0.1 show the next message.

    CMCI ON VERSION 1.1.0.1

    CICSExplorerServiceData-20120201-034831.zip
    CMCI ON VERSION 1.0.1.2

    CICSExplorerServiceData-20120201-035123.zip

    The two version are tested from the same IP adress.

    CNX0104E Connection failed with exception El tipo de elemento "META" debe terminar con el código de fin correspondiente "</META>".
    what it means?

    Hi there,

    Looking at the trace, the one that works is on port 9000:
    2012/02/01 03:48:25.195 CST [1] > com.ibm.cics.sm.comm.AbstractSystemManagerConnection.openConnection() [com.ibm.cics.sm.comm.cpsm.CPSMConnection@73c273c2Z099062@180.176.35.130:9000], http://180.176.35.130:9000/CICSPlexSM/ENU1/Z099062/DATA/DISCARD
    <snip>
    2012/02/01 03:48:25.195 CST [1] - com.ibm.cics.sm.comm.cpsm.CPSMConnection.discard() 200, Document follows

    And the one that fails is on port 9002:
    2012/02/01 03:51:12.689 CST [4] < com.ibm.cics.sm.comm.AbstractSystemManagerConnection.openConnection() sun.net.www.protocol.http.HttpURLConnection:http://180.176.35.130:9002/CICSSystemManagement/CICSCICSManagingAddressSpace//?NODISCARD=NODISCARD&SUMMONLY
    <snip>
    2012/02/01 03:51:12.736 CST [4] ? com.ibm.cics.sm.comm.sm.internal.SMCPSMConnection.get() java.net.SocketException: Unexpected end of file from server

    So I think this is the first thing to investigate. I suspect that 9002 is a valid port for some other kind of http service which is passing back a <META> tag that CMCI wouldn't.

    Sorry about that - should have previewed the message first. If only I could edit it to pop in some
    
    code
    
    tags :-)
