No Listener During Net8 Test

Hi! i installed Oracle 8i Pe ver 8.1.6 on Win98. all went fine but the problem is on the connection part.
When i tried to configure the service Net8 using Net8 Assistant, i just cannot connect to the database service with the error of "No Listener" (i'm using userid "scott" and password "tiger")
my host name is pingchian
below is my tnsnames.ora listing:
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
ORACLE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = pingchian)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = oracle)
and this is my listener.ora listing:
LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = pingchian)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = oracle)
(ORACLE_HOME = C:\Oracle\Ora81)
(SID_NAME = oracle)
(SID_DESC =
(PROGRAM = extproc)
(SID_NAME = PLSExtProc)
(ORACLE_HOME = c:\Oracle\Ora81)
what went wrong??
pls help..
thank you.

Hi,
Have u started the listener?? check wether the listener is started or not by using the below command..
D:/> lsnrctl status
If the listener is not started start it using,
D:/> lsnrctl start <listener_name>
Hope this helps,

    Toplink session is configured to use external transaction controller and data source. Application run on OC4J 9.0.4.1. Using jdbc debug options I wasn't able to find any causes. Has anyone faced this problem before?
    Regards
    Jarek

    Hi Jarek,
    TopLink uses the datasource similar to any other java application would, so there are no additional restrictions. From the error, you can see that the datasource is attempting to create a new connection and that is what is causing the exception. All TopLink did was call getConnection on the datasource ( DriverManagerDataSource.getConnection ).
    This could be a problem/glitch with the network or that the listener when down temporarily. Things to check would be:
    -how frequently this occurs
    -if it occurs for all connections after this point
    -the state of the database listener (can other applications connect to it, is it up, etc)
    -how many connections to the DB are active at this point
    -how many connections/sessions are active from this application
    -the OC4J and JDBC versions. Latest patches are better with regards to connection pools.
    What is strange though is that you have the min=max, so it should never create new connections after the first time the pool is accessed. Each connection should already have been created, which is why I suggest that you contact OC4J/JDBC support.
    Best Regards,
    Chris

  • How to measure memory consumption during unit tests?

    Hello,
    I'm looking for simple tools to automate measurement of overall memory consumption during some memory-sensitive unit tests.
    I would like to apply this when running a batch of some test suite targetting tests that exercise memory-sensitive operations.
    The intent is, to verify that a modification of code in this area does not introduce regression (raise) of memory consumption.
    I would include it in the nightly build, and monitor evolution of summary figure (a-ah, the "userAccount" test suite consumed 615Mb last night, compared to 500Mb the night before... What did we check-in yesterday?)
    Running on Win32, the system-level info of memory consumed is known not to be accurate.
    Using perfmon is more accurate but it seems an overkill - plus it's difficult to automate, you have to attach it to an existing process...
    I've looked in the hprof included in Sun's JDK, but it seems to be targetted at investigating problems rather than discovering them. In particular there isn't a "summary line" of the total memory consumed...
    What tools do you use/suggest?

    However this requires manual code in my unit test
    classes themselves, e.g. in my setUp/tearDown
    methods.
    I was expecting something more orthogonal to the
    tests, that I could activate or not depending on the
    purpose of the test.Some IDEs display mmeory usage and execution time for each test/group of tests.
    If I don't have another option, OK I'll wire my own
    pre/post memory counting, maybe using AOP, and will
    activate memory measurement only when needed.If you need to check the memory used, I would do this.
    You can do the same thing with AOP. Unless you are using an AOP library, I doubt it is worth additional effort.
    Have you actually used your suggestion to automate
    memory consumption measurement as part of daily builds?Yes, but I have less than a dozen tests which fail if the memory consumption is significantly different.
    I have more test which fail if the execution time is siginificantly different.
    Rather than use the setUp()/tearDown() approach, I use the testMethod() as a wrapper for the real test and add the check inside it. This is useful as different test will use different amounts of memory.
    Plus, I did not understand your suggestion, can you elaborate?
    - I first assumed you meant freeMemory(), which, as
    you suggest, is not accurate, since it returns "an
    approximation of [available memory]"freeMemory gives the free memory from the total. The total can change so you need to take the total - free as the memory used.
    - I re-read it and now assume you do mean
    totalMemory(), which unfortunately will grow only
    when more memory than the initial heap setting is
    needed.more memory is needed when more memory is used. Unless your test uses a significant amount of memory there is no way to measure it reliably. i.e. if a GC is perform during a test, you can have the test appear to use less memory than it consumes.
    - Eventually, I may need to inlcude calls to
    System.gc() but I seem to remember it is best-effort
    only (endless discussion) and may not help accuracy.if you do a System.gc(); followed by a Thread.yield() at the start it can improve things marginally.

  • AppContainers_test fails with error during pre-test configuration checks

    Hello,
    AppContainers_test fails with error during pre-test configuration checks:
    "[FAIL] The machine is not properly configured for testing: the test directory "C:\Windows\SYSTEM32\" is not ACL'd to allow execute permission for "APPLICATION PACKAGE AUTHORITY\ALL APPLICATION PACKAGES"
    But that kind of permission for APPLICATION PACKAGE AUTHORITY\ALL APPLICATION PACKAGES was allowed, also i tried to allow full access, but error was the same.
    In the test WindowsFilteringPlatform_Tests, the same requirement "REQ - Wfp-based products must not block App Container apps operating within their declared network intentions by default" was checked successfully.
    How can i pass successfully AppContainers_test? 
    I installed lastest versions of QFE and filters on my server, but it didn't help.

    Hi M'Alerter,
    I have the same issue, have you found a solution to your problem ?

  • Errors encountered during perfromance testing

    While doing some stress testing on our WLS server we kept seeing the
    following errors:
    1) NullPointerException on NTSocketMuxer, error log follows:
    Tue Feb 22 05:08:28 EST 2000:<E> <NTSockMux> failure in processSockets()
    loop: GetData: fd=16764 numBytes=23

    at weblogic.t3.srvr.ExecuteThread.run(ExecuteThread.java, Compiled
    Code)
    This error doesn't seem to have any immediate impact, although it can't
    be a good thing and it seems to happen even at times when we are not
    doing stress testing. Also, it is very frequent that we see the above
    messages. We are running WLS 4.51 w/ Service Pack 5. I am wondering if
    this is a problem w/ Service Pack 5 since I don't see this on another
    machine running WLS 4.51 with Service Pack 4. Both are using JDK 1.2.2.
    2) Connection Rejected, error log follows:
    Tue Feb 22 07:08:16 EST 2000:<W> <ListenThread> Connection rejected:
    Login timed out after 15000 msec. The socket came from
    [host=207.17.47.141,port=11929,localport=443] See property
    weblogic.login.readTimeoutMillis.
    I know how to adjust this for this one. My questions on this are:
    If I set my readTimeoutMillisSSL (SSL in this case) from 15000 to 30000
    what does this exactly mean. Does this mean that instead of allowing a
    max 15 seconds for a connection to be established, now I am allowing 30
    seconds? Also, is this only for the initial connection establishment (ie
    user login), or does this parameter effect other aspects of the
    connection later on? What negative side effects would I encounter if I
    set this to 60000 (1 minute)?
    Finally, what can I do so that a connection does not take over 15
    seconds to establish? Note this is not the norm, just happens more often
    during stress testing.

    NativeIO = true
    ExecuteThreadCount = 40
    readTimeoutMillis=5000

    Java Application
    t3s and https (using WLS RMI)
    JavaSoft 1.1.7b
    typically Pentium 200 MHz or better w/ 64MB or more
    Basically our clients connect to our WLS server using RMI. Each client
    also has a callback object where the server sends event notification
    back to the clients. Most of the communication is back through these
    client callback objects. Its similar to a stock trading application in
    that 1 client incoming requests will generate 200 outgoing events (if
    for example there are 200 users on the system). The above observations
    where made while 25 very active users where on the system.

    Our environment is set up as follows:

    ExecuteThreadCount = 40
    readTimeoutMillis=5000

    t3s and https (using WLS RMI)
    JavaSoft 1.1.7b
    typically Pentium 200 MHz or better w/ 64MB or more
    Basically our clients connect to our WLS server using RMI. Each client
    also has a callback object where the server sends event notification
    back to the clients. Most of the communication is back through these
    client callback objects. Its similar to a stock trading application in
    that 1 client incoming requests will generate 200 outgoing events (if
    for example there are 200 users on the system). The above observations
    where made while 25 very active users where on the system.

    Hi Ginger,
    somehow, yes :-) I deployed the iFlow for customer master replication. After creating a customer the trace looked different and terminated at the reverse proxy. So the simple connect somehow is not able to do the same...

  • Monitoring WebLogic During Performance Test

    I am running performance tests on our WebLogic Server and would like to be able
    to pull the Thread Queue Length, Thread Queue Throughput and Java Heap % statistics
    that are displayed in the WebLogic Console and put them in a text file every so
    often during the test. This way I can use those statistics with others I collect.
    I assume that if the console is able to display this information that it must
    be available. Does anyone know how I could do this?
    Thanks In Advance

  • WLS dies during stress testing

    We're using JMeter to send continuous requests to the server. It creates
    1500 threads and each requests Hello.jsp (see below) 500 times.
    The server runs fine for about 6.5 minutes (serviced ~120000 requests)
    before locking up. We let it sit for a while and about 4 minutes later, it
    starts spewing out the following (bottom part of weblogic.log)

    WLS 5.1 with SP3
    Solaris Performance Pack is used
    Sun JDK 1.2.2
    min heap size is 128MB and max as 128MB with options

    tcp_close_wait_interval=10000
    tcp_flush_fin_wait_2=10000
    No paging/swapping takes place during the test.

    Thanks, that definitely sheds some light on the problem.
    We monitored the server and came up with the following. The queue isindeed
    growing and probably accounts for the eventual failure (does anyone know
    what the limit is?). The throughput is constant but just can't keep upwith
    the requests. Another thing is that the heap slowly increases along with
    the queue and it took a while for it to hit 100% and have GC occur.I am not sure about the limit. Either 32K or 64K, I guess. If you monitor
    your queue lenght frequently, you might have a chance to spot that limit.
    Every request need memory to hold. So the heap slowly increases along with
    the queue.
    >
    Now, we duplicated the test but accessed a Servlet directly instead of a
    JSP. This servlet simply did some out.print(...) statements to displaythe
    same page as Hello.jsp. This ran without a hitch. We had about 5 times
    more throughput and the queue wasn't growing out of control. Also, theheap
    would reach 100% much quicker and GC occured more frequently. I can't see
    how handling a JSP request is that much more resource intensive than a
    Servlet request...
    We then tried the original test again (accessing JSP) but this timeremoved
    Service pack 3. We were running straight WLS 5.1 (no service packs).
    Everything behaved nicely (just like the Servlet test did). Could it then
    be that SP3 introduced a bug relating to how JSP requests are handled?Well, if this was the case, you might need to address this with support.
    >
    Finally, all the tests ran without changing the default number of execute
    threads (15). I don't think increasing the number will help seeing how
    short-lived these requests are. I think more execute threads would just
    increase the context-switching.I agree. I've seen 15 to 60 threads in production. Might be worth a try to
    use larger number of threads in your test to see if it alleviated the
    problem.

    WebLogic has its interal request queue to enqueue all requests. Therequest
    refers to an unit of work for weblogic to process, such as a triggeredtime
    service, http request, etc. The finite number of worker threads defined
    in
    your weblogic.properties file will dequeue the requests inside therequest
    queue and process the work.
    There is an upper limit on the size of this queue. The message you gotmeans
    that your test hit that limit. In practice, if there were lots of
    requests
    inside that queue, every request need to wait for lots of time beforebeing
    processed (the queue is FIFO I believed). Open your WebLogic Console and
    monitor the size of the queue, in your test or in your production, if
    you
    see the size of the queue increases constantly, there is somethingwrong.
    You might need to increase the number of threads to handle the load. If
    tuning up the number of threads doesn't help, you might need useweblogic
    clustering (or add more servers in your clustering) to share the load.
    WebLogic engineers might be able to lift up the upper limit of the sizeof
    the queue. However, the larger upper limit on the queue might not helpyou
    in practice. Tuning your configuration and making sure the number of
    requests inside the queue do not increase constantly might be a good
    practice to follow.
    My 2 cents.

  • Best way to remove/add server from farm during LB testing

    Hi All,
    I've been tasked to assist dev team perform load balancing test.  There will be two servers in the server farm. What is the CLI command to toggle a server out of a server farm during the test?  Also what is the show command for verifying which server in the pool have the sessions?
    This is the test plan:
    •1.       Open sessions to each of the Test servers to verify that they are working
    •2.       Open session to the VIP for the Test environment, and identify which server has the VIP connection
    •3.       Take down server #1 (assumed) of the Test environment
    •4.       Verify that #1 server is down, and that the VIP session switched over to #2 server with minimal interruption
    •5.       (consider interfaces to other systems)
    •6.       Start new session and verify that it goes to #2 server
    •7.       Bring up #1 server and take down #2 server
    •8.       Verify that #2 session down, and both VIP sessions switched back to #1 server
    •9.       (consider interfaces to other systems)
    •10.   Bring up #2 server
    Thanks in advance,
    Adil

    Hi Adil,
    To get the server out of loadbalancing equation, you can simply go to serverfarm and do "no inservice" for the server you intend to take out or you can make the probe to fail or you can simply take the server out of serverfarm by doing "no rserver .
    Also, regarding your testing, if you have two servers to which traffic will be loadbalanced, connection failover will not happen. Existing connections would be dropped or RST(depending upon what you configure) and new connections would be sent to server 2.  Once the server 1 comes back up, the connections would again start getting loadbalanced to both servers. You cannot have failover of connections from 1 server to another in same serverfarm.
    Let me know if you have any questions.
    Regards,
    Kanwal

  • Fan Activity during hardware test

    hi everyone,
    when i start the hardware-test, the fan of my mac is speeding up to maximum level. it happens when i hit the hardware-test button in the "start-up-disk window". is this okay?

    Dear klangapparat,
    Welcome to Apple Discussions.
    The fan are running high during the Hardware test because the unit is in the firmware mode which is at a very basic level , kind of only assembly code runnig to let the unit do some task. However when you load the OS then the the OS has a code and a driver running for each and every hardware. There is a code which is responsiable for the speed of fans that code is missing during the test so the fans run at full speed. There is nothing controling the fans speed.
    Hope this information helps.
    Good Day!
    Ravi Dimri.

  • Frozen during hardware test

    My macbookpro has frozen during the probe part of the hardware test (start using disk in drive, hold down "d"). It's been something like half an hour...
    This is NOT during the test part. It's not even giving me those options yet (button greyed out).
    What do I do now?

    Just hit the power key. It seems to have started ok.

    Thanks for the ideas regarding beforeInvoke, Ben.  I will try to check that out.  In my situation, here's essentially how my script is working...
    BeforeSave is invoked.
    Script makes a change to the document, which should be captured in the saved file.
    Document saves.
    Document appears saved for a moment, and then appears unsaved (asterisk in the document title).
    My biggest problem is that this behavior isn't consistent.  I have dozens of users, all running the same script, and the problem only occurs with certain users and at random times. I can move a problematic document from a user's machine to a different machine, and the problem doesn't occur there.  It's very difficult to troubleshoot because I can't reproduce it consistently.

  • No Subwoofer during games or music, but audio heard on it during speaker test...

    Hi all,
    I really hope someone can help me with my problem. I recently purchased a Yamaha A/V Receiver that has a Multi-Channel Input (Model: HTR-5835). I have an Audigy 2zs gamer card and I am running three Mini (3 pole) to RCA adapters into the three seperate channels on the multi channel input.
    I assume all the speakers are set up correctly because during both the Receiver's AND the THX control panel speaker tests I could heard audible noise coming from my subwoofer. I can also set the receiver to tuner and listen to the radio with the subwoofer.
    I have CMSS turned on and I have listened to MP3's through winamp and WMP and there was no subwoofer, but all other channels (including center) worked fine. I also tried playing BF942, WoW, guild Wars and Doom 3 with no subwoofer sound at all.
    Does anyone have any ideas or a solution to figuing out this issue? I have been wracking my brains and searching the net for 3 days to no avail.
    Thank you.
    Ndy

    It's in Bass Management section of the Speaker Settings. Bass Boost will be greyed out with 5.1/6.1 or 7.1 speakers as it is meant for 2.1 and 4.1 systems.
    <IMG height=335 src="mk:angry:MSITStore:C:\Documents and Settings\Paul Cook\Local Settings\Temporary Internet Files\Content. IE5\WDA3CDI7\A2ZS[].chm::/images/spkr settings.gif" width=499 border=0>
    It should be possible to get a decent output from the sub when using the bass redirection. This will give you 5.1 when upmixing with CMSS or playing games and 2.1 with stereo sources. If your sub can't amplify the signal enough, you may need to put a small preamp in between the soundcard and receiver to boost it. You could make one yourself if you're into electronics, there will probably be lots of preamp circuit diagrams on the web. DWH explains why the sub output is lower than the rest here:
    http://forums.creative.com/creativel...id=8533&page=2.
    You could also go for a more expensive fix, which would be to use a crosover like this one in between the soundcard and receiver:
