Query IDs in ORACLE_SEM_FS_NS : 32 or 64 bits?

Hi,
I have a question regarding query IDs used in ORACLE_SEM_FS_NS prefix definition and in Joseki / Oracle querymgt servlet.
It seems that :
* ORACLE_ORARDF_QUERY_MGT_TAB table apparently can hold longs
* the querymgt servlet accepts longs and returns "No valid query ID specified." for anything over 64 bits.
* running queries with long qid (either from a Joseki endpoint or from Jena) results in weird behaviour :
** qid < 2^32 : OK
** qid < 2^64 : returns either an exception (see below) or an empty result set immediately (with no exception)
** qid > 2^64 : query runs OK but qid cannot be used to stop query since it is over 64 bits
Here is the exception shown if you use a qid between 32 and 64 bits :
Exception in thread "AWT-EventQueue-0"
java.lang.NumberFormatException: For input string: "8947349906"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:459)
at java.lang.Integer.parseInt(Integer.java:497)
at oracle.spatial.rdf.client.jena.OracleQueryContextParameters.getQID(OracleQueryContextParameters.java:83)
My question: due to the discrepancies when using large values, I do not exactly understand : are the query ids meant to be 32 or 64 bits ? Moreover: I haven't checked whether the id was signed or unsigned. Could you please specify exactly the range of possible values that qid can be assigned ?
Thanks
Regards,
Julien

Hi Julien,
My comments are inline.
Cheers,

Well, to be honest, I cannot reproduce the issue I faced yesterday. The weblogic server providing Joseki was overloaded for some other reason (out of memory) and was only responding to querymgt queries (the SPARQL queries themselves were stuck threads).
Regarding the 4th point of your explanation : When you say that "the Jena Adapter" polls the DB regularly to check if any query needs to be killed, do you mean that the following would work ?
Example : A user runs a SPARQL query via a load balancer that uses two instances of Joseki w/ querymgt. The same user then wants to kill the same long-running query via the same load balancer and hits the other instance of Joseki w/ querymgt.
V: The two instances of Joseki are using the same datasource right? In that case, the kill request will be sent to both Joseki instances.
If I understood what you said, the query management features are only available for queries ran through Joseki since they are stopped on the client side. In that case, is there a way to stop long-running queries that are sent directly through JDBC (using Jena adapter) ?
V: If you submit a SPARQL query programmatically through the Jena Adapter against an Oracle-backed GraphOracleSem, and you specify a QID in the prefix, then the query is registered and you will still be able to kill it using the querymgt servlet. Let me know if this answered your question.
Regarding the first question (available values for qid), do you plan to fix the fact that only less than half of all 32-bit values are available ? I am asking this because it is quite common to use 32-bit (or multiples of 32 anyway) IDs for instances / sessions of client applications and it seems to me that it would make it easier to use query IDs.
V: We will look into allowing 64-bit query IDs in the next Jena Adapter release.

  • Trouble Turneing on FileStream/Ad Hoc Query with new SQL Server 2014 64-BIt Version

    SQL Server Help,
    I have recently installed SQL SERVER 2014 on my Window 7 SP1 Acer laptop.
    I am trying to do a simple upload of an Excel file into SQL Server using the OPENROWSET command:
    Which I found requires some configuration change I attempted below.
    When I execute this:
    execute sp_configure 'show advanced options', 1;
    RECONFIGURE;
    execute sp_configure 'Ad Hoc Distributed Queries', 1;
    RECONFIGURE;
    GO
    I get this message
    Configuration option 'show advanced options' changed from 1 to 1. Run the RECONFIGURE statement to install.

    "There was an unknown error applying the FILESTREAM settings.  Check the parameters are valid (0x80070002)."
    Perhaps my issue is with the Windows Share Name:  .  I have put in a local driver C:\A_Excel....also the computer name, my user ID.   Is there a special format or way to define a Share Name that I am unaware of?
    Is there a way to fix this?  Can I not load Excel files with a 64-Bit system?  Or what is the easiest way that I can do this with my configuration?
    Thanks for any help.

    FILESTREAM feature is not supported on WoW64. The feature is disabled.
    By the error message it seems you have a 64 bit OS, but have installed a 32 bit SQL Server and here in WoW64 mode filestream seems to be not supported. Install a 64 bit SQL Server instead.

  • Power Query Update 2.16.3785.242 (64-bit) has Corrupted Excel

    The most recent update to Power Query has rendered Excel useless.  Any use of the Ctrl key (copying, pasting, etc.) will cause Excel to crash and restart.
    A co-worker had the same problem yesterday and we were perplexed in its origin, though it became clear the update was the source after updating this morning.
    We need a fix ASAP!

    Hi W. If you can still repro the crashes, can you please do the following to get a crash dump and then send it to us? (You can use the Send a Frown functionality on the working version of PQ.)
    Edit the registry, open the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Windows Error Reporting and change the DWORD value ForceQueue to 1
    Open %LOCALAPPDATA%\Microsoft\Windows\WER\ReportQueue in Windows Explorer to monitor it
    Reproduce the crash – at this point something should appear briefly in the ReportQueue folder 
    Thanks,

  • PREFIX ORACLE_SEM_FS_NS timeout via Jena Adapter

    Hi,
    I am executing SPARQL via Jena Adapter and would like to specify timeout.
    I use PREFIX ORACLE_SEM_FS_NS: <http://oracle.com/semtech#timeout=5> , according the the sem dev guide Jena examples, but the timeout value has no effect at all.
    For some heavy queries QueryExecution->execSelect() never returns
    I found this thread - Re: Query IDs in ORACLE_SEM_FS_NS : 32 or 64 bits? , which discuss the similar subject. I tried to add qid to the prefix, but that did not help. I don't use Joseki endpoint nor OracleQueryMgtServlet to manage(kill) long queries. Maybe I will provide the latter function in the future, but I would like to start with that users specify the timeout and query would interrupt itself if not ready.
    So, is there anything else I have to do in Java/Jena code or somewhere else?
    Thanks, best regards
    Jürgen
    After some more testing it turns that the problem with timeout is related to certain type of queries only. Normally the timeout works.
    But when LET statement is used in some way, then timeout does not occur and it seems the query simply hangs:
    This query works and times out (if timeout value is set short enough):
    SELECT DISTINCT
    ?HR_Zone
    (count(?e) AS ?major_count)
    WHERE {
    ?e rdf:type r:ST_Episode .
    OPTIONAL
    ?e r:isClassifiedAs rn:major_st_episode .
    OPTIONAL{
    ?e r:mappedHRZone ?zone .
    ?zone r:index ?HR_Zone
    GROUP BY ?HR_Zone
    This query does not finsih (in boundaries of my patients) and does not time out:
    SELECT DISTINCT
    ?HR_Zone
    (count(?e) AS ?major_count)
    WHERE {
    ?e rdf:type r:ST_Episode .
    OPTIONAL
    ?e r:isClassifiedAs rn:major_st_episode .
    LET( ?emajor := ?e )
    OPTIONAL{
    ?e r:mappedHRZone ?zone .
    ?zone r:index ?HR_Zone
    GROUP BY ?HR_Zone
    However, one might think that LET is not supported - but without ARQ functions it works. This query works and times out (with short timeout value)
    SELECT DISTINCT
    ?emajor ?HR_Zone
    WHERE {
    ?e rdf:type r:ST_Episode .
    OPTIONAL
    ?e r:isClassifiedAs rn:major_st_episode .
    LET( ?emajor := ?e )
    OPTIONAL{
    ?e r:mappedHRZone ?zone .
    ?zone r:index ?HR_Zone

    Hi Jurgen,
    The timeout pragma is most effective when used with SPARQL 1.0 queries, since they are supported natively. Once you start using ARQ features - which are not available in Oracle so they are processed in the mid-tier - timeout becomes less reliable.

  • Can we stream music and photos from two Apple computers (different Apple IDs) to home theater?

    Purchased Apple TV last week; both computers are running most recent versions of iTunes and Apple Aperture. Apple TV connected via HDMI to AV Receiver.
    Computers are macbook pro and iMac.  Bot running most recent (10.9.1)  version of operating system.

    We discovered that it was easier to keep one iTunes ID in Apple TV and have the second iTunes ID join using Airplay through an iphone or ipad.  The switching of user IDs in Apple TVs seemed a bit clunky to us, especially with the awful interface using the Apple TV remote.  We did not want to have the second iTunes ID password saved in the Apple TV since several of our kids use that TV, and wanted to prevent large iTunes bills.
    Thanks again for the information.
    We like the Apple TV.  However, we have discovered that the wifi is the Aquilles Hill of this devise.  Our ISP offers 50 mbps download speeds from the internet (i tested it using one of the internet speed measuring sites) And the router at home supports 802 g and n proptocols.  The transmission of photos from Macbook Pro to Apple TV was incredibly slow.  Most likely the problem is caused by having the Apple TV near the floor and next to a fireplace; wireless signal has to travel through a physical firewall.  We solved the problem by buying an adaptor that connects to the wall and the router using ethernet cables; signal travels through the electric outlets to another adaptor that is connected  from an electric outlet to the Apple TV via ehternet as well. This improved the experience with this devise quite significantly.

  • Query in RSRREPDIR with Exclamation Pointes

    Hi, I am seeing query ids in table RSRREPDIR that begin with either ! or !!.   I am guessing that these are temporary or virtual queries created from web analyzer using an infocube as a source.  These "Queries" do not show up in the MetaData Repository or in the Bex Analyzer..
    Does anyone know how these get created and how I might be able to remove the entries from table RSRREPDIR?
    Thanks for any help with this...

    Dear KM,
    True these are virtual queries and these are generated in RSRT by providing INFOCUBE/!INFOCUBE name as a query name.
    This action will generate a query containing all Key Figure and Characteristics from this InfoProvider.Such kind of objects are really virtual.
    But I would suggest you to not to delete them.

  • The Query Question.

    Hi everyone.
    I created a Query button. And the MB's code is:
    ApplicationModule am=ADFUtils.getApplicationModuleForDataControl("HrModuleDataControl");
    ViewObject vo=am.findViewObject("HrHumanView1");
    int tmp=vo.getCurrentRowIndex();
    vo.setNamedWhereClauseParam("HumanSort","abc");
    vo.executeQuery();
    vo.setCurrentRowAtRangeIndex(tmp);
    There is 100 records in my database,and the view of HumanSort='abc' have 30 records. If I execture other query operate, for instance,there is 70 records left, next I execture this query operate, the result doen't query from the 70 records,it still query from 100 records.
    And on other page, I have a button used the same MB's method. It query from the 70 records.
    I don't understand it.
    I have already set the task flow 's Data Control Scope to shared.
    Help me.Thanks.

    I didn't quite understand the problem that you are having, sorry.
    First, you can accomplish what your code above is trying to do using declarative features of ADF. The ExecuteWithParams built-in operation assigns values for named bind variables of a view object then re-executes the query.
    You need to provide a bit more details about what you mean by "I execute other query operation" (how was this first step achieved? declaratively? using code?) followed by "next I execute this query operation" (assuming you mean the code that sets the bind variable value).
    It sounds as if you're expecting the second query to further-filter the results of the first query, but I need to understand better what you did in the first step to let you know if what you're seeing is expected behavior or not.

  • Problem with SQL query generated by setString

    Using Creator 2EA2 I have a rowset based on this query (it's actually only the last bit of it with the third parameter that is a problem):
    SELECT director.director_id,  director.name FROM director, director_last_modified WHERE name REGEXP '^[A-C]'  AND director_last_modified.dir_last_modified > ? AND director_last_modified.dir_last_modified <= ?  AND director.director_id = director_last_modified.director_id AND director_last_modified.dir_flagged = ? ORDER BY name; I use setObject to set the first and second parameters to a date. The third parameter refers to field in the database which indicates whether or not a director is 'flagged'. It's a TINYINT in a MySQL table and may contain either 0 or 1. If the user wants to see 'flagged' directors, I want to set the third parameter to 1. If they want to see all directors I want to set the third parameter to 0 OR 1.
    So I use setString with a String variable for the parameter:
    setString(3, strCriterion3);If strCriterion3 has been set as follows:
    strCriterion3 = "1";the generated SQL query ends with:
    director_last_modified.dir_flagged = '1' ORDER BY name; JDBC supplies the two apostrophes. So it would seem to follow that in order to produce a query which ends with:
    director_last_modified.dir_flagged = '1' OR '0' ORDER BY name;I shoud set strCriterion3 with:
    strCriterion3 = "1' OR '3";
    in order to get the required apostrophes.
    However, the generated query is then:
    director_last_modified.dir_flagged = '1\' OR '0\' ORDER BY name;How do I get rid of those backslashes? I've tried double apostrophes, by the way - that just gives me more backslashes.
    Thanks for any help you can offer.

    [Sorry, but I missed the parentheses from the query. It should end with:
    [code]AND (director_last_modified.dir_flagged = ?) ORDER BY name;
    - not that that makes any difference to the apostrophes problem.]
    I've just discovered a solution in this thread http://swforum.sun.com/jive/thread.jspa?forumID=123&threadID=56228
    So I've replaced = ? in the query with LIKE ?
    I then set strCriterion3 to either "1" or "%". That will do nicely, but it seems a bit of kludge and, under different circumstances, I'd still need to get rid of those pesky apostrophes. Any ideas?

  • Power Query SCCM Installation

    I have been trying to create a SCCM application which will install Power Query after installing MSOffice Pro Plus 2013. On a machine which has the Office, I can manually install Power Query, however, silent and administrative installs do not work. 
    Has anyone successfully install Power Query through System Center as a system application (no user interaction)?  If so, what am I missing.
    Steps taking so far:
    Downloaded latest Power Query Software: "PowerQuery_2.13.3688.242 (32-bit) [en-US].msi"
    Created a new application from the MSI.
    Created a deployment.
    Tested deployment on Windows 8.1 Machine. Failed to install.
    Tested deployment on Windows 7 Machine. Failed to install.
    Tried on both Windows 7 and 8.1 Machines to install by command line (admin command prompt) with /a or /I with /qn and will not install.
    In event viewer return code is installation success or error status: 0.
    Verified com add-in is not present.
    Tried on Windows 7 and 8.1 machines installing with no flags and installs successfully.

    This command works when I run cmd as Administrator on local machine (non-domain joined). But when cmd runs as a regular user (this user is local admin) it fails. SCCM tries to run it as local admin.
    SCCM gives following error: 0x643 (1603).
    Google says that it is related with elevation. Note: Run as Administrator feature blocked on client machines through GPO.
    Could someone help me?

  • Trouble installing Mavericks over Lion on iMac 12,2; hangs.

    Hi Folks,
    iMac 12,2 16 Gigs RAM, i7  4-core 3.4 GHz 1-TB HD for data, 1-250 Gig SSD for systems - running Snow Leopard on one partition and Lion on the other. (Full hardware description at bottom.)
    Purchased new in New Zealand about 14 months ago from Apple authorized reseller; no AppleCare. Not registered with Apple. No seerrious problems since, until this.
    Ethernet lan connection to Airport and then ISP's modem/router (Telecom New Zealand, . Fixed IP. No problems there, I think.
    Lots of USB stuff plugged in during install, but that shouldn't matter.
    Attempt to install Mavericks on Lion partition while booted in Lion partition failed.
    Attempt to install Mavericks on Lion partition while booted in Snow Leoepard partition failed.
    (Download to Snow seemed to work fine. Installer ran, finished in 20 minutes instead of 35, but when I restarted the computer the startup hung. Shutdown, restart, hangs. Every time.)
    Both installations failed with this hang. Restarts done with verbose logging on show the following, repeating ad infinitum (I stopped counting after it got over 5,100 lines -- no I didn't watch 5,000 lines scroll, I went away for a snooze):
    invalid sandbox profiile for pid <number> (invalid regex)
    Nothing here in the forums, or on the InterWebs about this error or much about a hanging install (which has been identified as one of Mavericks' problems) except to say wait forever (I  think 5,000 lines of verbose logging is forever) or try the install again. I have tried the install again; it hangs at the same point every time.
    There is some stuff on the hacker sites about sandbox and this error, but only for earlier OS versions. The fix for them was to replace the sandbox.kext. I'm going to boot into root in Snow Leopard partition so I can do things to the Lion partition, and change that kextfile?! Yeah, Riiiggghhhhttt. NOT.
    I suppose I could try the install with all USB stuff disconnected -- but I don't believe that's it.
    I suppose the fact that the Lion might not have had the latest software updates to it before I tried to install Mavericks might have something to do with it. I don't believe that's it (certainly is shouldn't be).
    Final recourse might have to be wiping the Lion partition (full erase and clean install) (it doesn't have any critical data saved on it; I do all my work in Snow on the other partition, the Lion is for experimenting).
    Anyone have any ideas?

    Sorry, bad news for you, depending on your setup.
    The answer (provided by an Apple higher-level tech for which I paid -- no Applecare) was that they don't have a clue, but a clean install works.
    Yeah, Thaaannnnnnnkkkksss. Knew that.
    Clean install (almost) always works (worked) for 25 years.
    You don't say if your kit has everything on one partition, or there are more than one.
    If you have a big hard disk that's not full, has lots of room, but only one partition, with 10.8 you can dynamically create a new partition without losing data. I don't have the details of the process handy, but it's pretty straightforward.
    Then, with the Mavericks installer on the 10.8 partition, and booted to that partition, you can install Mavericks on the other partition (with administrator account). You could use the migration assistant (or whatever) to bring your data over from the 10.8 partition to the Mavericks one. However ...
    You might also want, if your hard disk isn't huge, and you don't have two drives of whatever type in the machine, to make the new partition just big enough for the OS and apps, and keep the data on the 10.8 partition.
    You can tell the Mavericks instance to use the other partition as your Home directory, instead of the Home directory on the Mavericks drive.
    If you have your OS and data on the same partition, and you don't have enough room on your disk(s) for the above procedures, then your best solution would likely be make a Carbon Copy Clone of the drive, wipe it completely, and install Mavericks from some external source other than another partition with another OS, and migrate your data back.
    There is stuff on the Web about making a bootable Mavericks install disk on a flash memory stick.
    But whichever way you end up doing it, you will have to boot into a clean OS on a different partition or disk from the target Mavericks install partition or disk.
    Last caveat: it may be difficult, but not impossible, to maintain your, or multiple users', identity and accounts and where they point, as well as your online IDs.
    Hope that helps a bit. Don't give up, but do take precautions (a CCC backup or a Tiime Machine is always wise anyway) and write everything down as you go.
    FWIW, I'm not using the Mavericks partition for anything, not even experimentation. I'm still using my Snow Leopard, because it works fine (finally) and is the only way to run Eudora. Until, that is, I solve the problem of running 10.6.8 server in a virtual machine in the Mavericks partition so I can run Eudora under Steve's nose with impunity, and so seamlessly it seems to be running under Mavericks, with full integration (through Parallels).
    Cheers from the Antipodes,
