WAITED TOO LONG FOR A CACHE LINE ENQUEUE LOCK!

Hi all

Ora10g

All of a sudden this afternoon users have complained that they are unable to connect to the database, I tried to log in and was able to confirm that suspended connection.

I checked the alerts log and I found these:

How do i resolve this error please....

Well looking at alert.log, you encountered two issue a)ORA-3136 and b) WAITED TOO LONG FOR A ROW CACHE ENQUEUE LOCK

For a) ORA-3136 , please follow the below metalink note which explains about the resolution for this. You might need to increase SQLNET.INBOUND_CONNECT_TIMEOUT from 60 to slight higher.
Following the note from MOS
Troubleshooting ORA-3136: WARNING Inbound Connection Timed Out [ID 465043.1]


The default value of 60 seconds is good enough in most conditions for the database server to authenticate a client connection. If it is taking longer, then it's worth checking the following items before implementing the workaround: 

1. Check whether local connection on the database server is successful & quick.
2. If local connections are quick ,then check for underlying network delay with the help of your network administrator.
3. Check whether your Database performance has degraded in anyway.
4. Check alert log for any critical errors for eg, ORA-600 or ORA-7445 and get them  resolved first. 

As you said that users could not connect to the database, so above may be the reasons for what you need at the Fund.

Second, you got the warning message "WHEREAS TOO LONG for A LINE CACHE ENQUEUE LOCK", which is also linked to the shared pool.

Make a small conclusion on two question above, it seems that your shared pool size is not enough. For this you must check AWR reports during this difficult period and confirmation that there is not any event of related waiting for shared pool.

  • Error compiling FPGA-61332: the length of a line to < "file.vhdl" > is too long for xilinx 10.1. Length: < length > Max Length: 4150

    Hello

    When compiling a fairly basic FPGA VI, I get the following error:

    Possible reasons:

    LabVIEW FPGA: An unexpected error occurred with the build tools. You try to compile the FPGA VI again could solve the problem.

    Apparently, the vhdl code generator OR forgot to add some CR + LF in the intermediate files. How to work around this bug?

    Kind regards

    Lukas

    Hi Lukas.

    When LabVIEW compiles a VI, the VI is converted into virtual hard disk to be compiled into a file bit by Xilinx.  As you have already understood, this error indicates that a line of code vhd had a length of 32 845 characters, which exceeds the maximum length of 4150 characters for the Xilinx 10.1.

    Although 32 845 characters is very long, it is possible that this is due to the codification of LabVIEW rather than a bug. Some common causes of this problem include large enums, a matrix, or clusters in the code.  Please check in your code.  If you have no luck, please attach a screenshot of the code.  I hope this helps!

  • use marker iff section is too long for the header

    Hello everyone,

    I wonder: is it possible to implement FrameMaker using a marker iff there is one on this page?

    Here's the problem: I have a book with several chapters of different authors. Some of them used topics that are too long for the headers. For those I want to use markers.

    I know how to display markers, which I don't want, because then I have to create a benchmark for each unique position in the book (using this master page). And I know how to view the different titles for example < $paratext [H1, H2, H3] >.

    Now I'm looking for is something like this < [marker, line] $paratext >. In plain language: 'check if there is a certain marker. If there is one, show the marker, otherwise display the heading."

    Then I would be able to use the same master page and would need to use markers only where a title is too long.

    Thanks in advance

    Dennis

    Dennis,

    Take a look at http://forums.adobe.com/message/3503638#3503638

    You could create an alternative heading tag (for example InvisibleH1) with an invisible color in a framework anchored to it and can then use the building block <$paratext[InvisibleH1,H1,H2... etc.]="">. Just toggle the views appropriate to hide text in anchored frames.

    N ° to check that what I say is correct, create a new folder
    for the purposes of the trial and to make a copy of some files. To ensure that
    one of them has a long name (rename if necessary), and then try to copy
    These files on the external drive. When you get the message, choose
    'jump' and see what happens.

    Not exactly:
    http://docs.Oracle.com/CD/E11882_01/AppDev.112/e25519/datatypes.htm#CHDDCGEE

    but this isn't the real problem.

    The error is about the "string literal" size, there is a limitation too:
    http://docs.Oracle.com/CD/E11882_01/server.112/e17766/pcmus.htm#sthref18132

    PLS-00172: string literal too long
        Cause: The string literal was longer than 32767 bytes.
        Action: Use a string literal of at most 32767 bytes.
    

    For the above, I fault the XML into several parts and run the PLSQL, then it gives no error.

    Is this a real case of production or you just test?
    In practice, we should first save the file in a variable/column CLOB (or XMLType) and then reference the content from there.

  • Path too Long for the Installation of the software

    I am trying to install a version of the CAD software to one of my PCs employee.  When we run the Setup file, we get an error message too long file path.  The message says that the file path is 99 characters long, but the limit is 93.  This seems like a terribly low limit for a C: drive.

    The path goes only in a folder as well.  Thus, its C:/Program Files/Autodesk / "name of file along here."

    I understand long path problems when you go deep in several folders and the typical character limit is 254.  I do not understand why we are running in a limited issue when you have only a single deep folder on the C: drive and only have 99 total characters in the path.  Is this a problem of windows 8?  Or maybe a problem with the PC itself?  Is it possible to change the limit of characters on the C: drive since 93 is so short and also seems to be a random number?

    Justin

    Your best bet is to contact the CAD developer, we would have no way of knowing how many levels deep the software installs.

  • Shuttle value too long for use in LOV sql cascading

    Hello

    On APEX 4.2.2.0.11 & Oracle 10.2.0.5.0:

    I have a shuttle service set up as well as a select list with of LOV cascading.

    The shuttle shows organization name and returns a list of the IDs of the colon separated.

    The selection list shows the so-called events belonging to the organizations selected in the shuttle.

    The selection list is implemented as LOV cascading with the shuttle as a parent element.

    This works fine as long as the length of the shuttle point value does not exceed 4000 characters.

    If so, the LOV - sql select list will give an ' ORA-01704: string literal too long "-error on the instr function ().

    This is the query:

    Select distinct TST. NAAM as display_value, TST.ID as return_value

    of the OTE ORGS

    Join the LIFO ADG ON (ADG. OTE_ID = OTE.ID)

    Join the DNR PART on (DNR. ADG_ID = ADG.ID)

    Join the TDR ON REGRET (TDR. DNR_ID = DNR.ID)

    Join the TEST TCT ON (TST.ID = RDT. TST_ID)

    where instr (': ' |: P1_ORG |) ':', ':' || OTE.ID | ') > 0

    order by 1

    Does anyone know how to make reference to the shuttle-value in sql, even if it is longer than 4000 characters?

    Well, I found a way to use LOVs cascading on page elements with values exceeding 4000 characters:

    Let's say I have a shuttle named P1_ORGANISATIE with "List of values" box, a dynamic LOV named "Source: lists of values Query" containing the value:

    Select NAAM as display_value, ID like return_value

    of NINEHAM

    order by 1

    If the number of records-NINEHAM is insufficient, the length of the value of P1_ORGANISATIE, which is a list of concatenated with colon separated digital ID, can exceed 4000 characters.

    Now suppose I have a list of selection called P1_TEST that is connected through "List of values"-> "En cascade LOV Parent article (s)" with P1_ORGANISATIE using a named LOV dynamics with "Source: lists of values Query" containing:

    Select distinct TST. NAAM as display_value, TST.ID as return_value

    of the OTE NINEHAM

    Join the AFDELINGEN ADG ON (ADG. OTE_ID = OTE.ID)

    Join the DEELNEMERS DNR ON (DNR. ADG_ID = ADG.ID)

    Join TESTDEELNEMERS TDR WE (TDR. DNR_ID = DNR.ID)

    Join TESTEN TST ON (TST.ID = RDT. TST_ID)

    where instr (":" |: P1_ORGANISATIE |) '':'', '':'' || OTE.ID | '':'') > 0

    order by 1

    In this case, when P1_ORGANISATIE exceeds 3998 characters, you'll get an "ORA-01704: string literal too long"-error and the P1_TEST will show an element called "undefined".

    A way around this is possible because for a named LOV, you can use a "function that returns a sql query" instead of a simple sql query. In other words, we can apply in the context of PL/SQL and thus have maximum for expressions of 32767 instead of 4000 characters. In addition, it is possible to use the two APEX_UTIL. STRING_TO_TABLE and APEX_COLLECTION.

    Setting "Source: lists of query values" on the LOV appointed to P1_TEST with the following code will work:

    DECLARE

    l_selected APEX_APPLICATION_GLOBAL. VC_ARR2;

    l_qry varchar2 (32767): =.

    "Select distinct TST. NAAM as display_value, TST.ID as return_value

    of the OTE NINEHAM

    Join the AFDELINGEN ADG ON (ADG. OTE_ID = OTE.ID)

    Join the DEELNEMERS DNR ON (DNR. ADG_ID = ADG.ID)

    Join TESTDEELNEMERS TDR WE (TDR. DNR_ID = DNR.ID)

    Join TESTEN TST ON (TST.ID = RDT. TST_ID)

    $1

    order by 1';

    BEGIN

    IF: P1_ORGANISATIE IS NULL

    OR LENGTH(:P1_ORGANISATIE)<=>

    THEN RETURN

    Replace (l_qry

    ,'$1'

    ,' where instr (":" |: P1_ORGANISATIE |) '':'', '':'' || OTE.ID | '':'') > 0'

    );

    ON THE OTHER

    l_selected: = APEX_UTIL. STRING_TO_TABLE(:P1_ORGANISATIE);

    APEX_COLLECTION. CREATE_OR_TRUNCATE_COLLECTION (p_collection_name-online 'ORGANISATIE_COLLECTIE');

    FOR id IN 1.l_selected.count

    LOOP

    APEX_COLLECTION.add_member (p_collection_name-online 'ORGANISATIE_COLLECTIE'

    p_n001-online to_number (l_selected (id))

    );

    END LOOP;

    RETURN

    Replace (l_qry

    ,'$1'

    ,'join apex_collections ON APC (APC. COLLECTION_NAME = "ORGANISATIE_COLLECTIE" AND APC. N001 = OTE.ID)"

    );

    END IF;

    END;

    Due to the import of my photo in iPhoto folder structure, I have a lot of double copies.  I have all the photos placed in iPhotos Trash and didn't know that it required a separate purge of the Mac OSx file bin.  So now it has been more than an hour and iPhoto always displays "iPhoto trash dump.  I don't know if it is abnormal or not, given the number of photos.  I only 8400 pictures so I have no idea why iPhoto reports plus 35 000.  I imported my files only once.  Is iPhoto 'hung up' or OSx is actually busy doing things to empty the photos?  Should I try a reboot forced my Mac, restore all photos or just wait it out?  For more information, the lesson learned.  Of course, it was easy to make this mess.  It just open iPhoto, import files, select all your folders and let it do it's thing.

    What version of iPhoto do you have?

    Some versions of iPhoto have a bug that prevents them from emptying the trash, if you put too many photos in the trash at a time. Then the thrash band will never deplete.  Try to take all the photos from the Recycle Bin and then trash only some hundreds of photos at once. And empty the trash immediately.

    Hi xploreaj,

    I noticed that often happens when a system has something like Norton or McAfee installed and that it has not been disabled prior to installation of the SP3.  If you encounter any other problems, then it is reasonable to assume that everything is ok.  However, you can also scan your system with Malwarebytes to see if there is no infections present which your current AV software has not picked up on. (how to use Malwarebytes: http://www.bleepingcomputer.com/virus-removal/how-to-use-malwarebytes-anti-malware-tutorial).

    Windows 8, I cannot enter my password wifi complete on my new lenovo yoga. My password is 26 characters and windows 8 will not allow me to enter the last characters actually cut me my wifi. I don't understand why this is happening. Any answer other than to change the password, would be useful.

    Hello

    1. why you want to keep your so long of the password of WiFi (26 characters)?

    2. you are bothered about securing your Wi - Fi connection?

    Minimum password length to at least a value of 8. If the number of characters is set to 0, no password is required. In most environments, a password of eight characters is recommended as it is long enough to provide adequate security still short enough for users to easily remember. This value will provide an adequate defence against a brute force attack. Adding to the complexity requirements will reduce the possibility of a dictionary attack. For more details on the same, see these articles:
