Event of LabVIEW transformation in an external library (DLL) :-(locks
Yes, I tested this solution and got to work.
I see why Labview creates its own queue for events in such a way that callback events are not processed within the DLL code is and are waiting to return in Labview.
And when I call the DLL inside another function that executes another asynchronous process (enumeration) this way active queue processing in the application.
It's a strange and not obvious situation.
I only discovered that all of a sudden this possibility during debugging.
I don't see other solutions and cancel this topic.
Best regards

Hi all!
Yesterday, I worked all day in a VI and today, unfortunately, I'm frustrated when I tried to open it. Received the following error message:
LABVIEW: Unable to load dynamic library due to lack of external symbols or dependencies, or a format file not valid. The "ENG633 v1.vi" file could not be loaded.
This message repeats when I try else open a Subvi.
Step by step:
1. I created a copy of the LabVIEW VI example: "FuzzyEx Tanks with control of PI." I kept the copy in the same original directory.
2 - I have edited the copy, created Subvi etc.
3 - once I finished my course of programming I closed all the cut (ctrl-x) files and copied (ctrl v) into the other folder.
4. then I tried to open the next day and... bug! I just couldn't do
What can I do to open/recover the VI?
I am using 32-bit LabVIEW 2016 in a Windows 10
I tried opening them and got the same error you did, so I them opened with a hex editor to see if there was something in the file, and there is literally nothing other than the value of 0x00 for the entire file.

Meet an applescript event in LabView 2009 (Mac OSX) VI
I have a LabView VI that works constantly, acquisition of data at a remote location. I recently bought a UPS for power cuts, and I would like to be notified by LabView by e-mail that an event has occurred. Can I have the UPS software run an executable when there is a power failure, so my question is this:
How to run an executable file (preferably AppleScript) and have it trigger an event in LabView 2009?
The main VI is still running, and I would like to respond to an event and send a mail/text to the appropriate personnel, so that they can respond accordingly to the power failure. In addition, if power failure, I can then stop the experience "smoothly."
It seems that all the pieces have to exist to do this, but I can't find a way to get there. Thank you in advance, this will make many people happy!
News: Mac OS X 10.5.8, LabView 2009
Hi jumpman Jr,.
When you say that the UPS software may run an executable file, which means that it can run an executable of LabVIEW? If so, you can write a small executable of LabVIEW to send an email to a specified address. In the measurement of the notifying the main VI that is running, you can try to communicate between the executable and the VI using the methods of normal communication of VI at VI, i.e. global variables, functional global variables, shared variable network published, or even tax filers or queues. Then you can safely leave your main VI.

Cannot compile OK after adding an external library lot
Hi all
I added flurry as external library in the cascades. So I find, I added wrong libarary.
So I deleted it in bar - descriptor.xml.
But when I compiled my always reported project.it I added incorrect library.
The config.pri file contains bad library path.
How can I delete an external library?
Thank you.

Fortunately, I've added the cproject file in my git repository. So I can go back to an earlier version.
I have zero my branch git, back to the last commit. Then replace the src directory and assets to the new directory.
The problem is resolved. It's complicated on the addition of libraries in Momnetics IDE.

Add an external library to a Javascript Ext
Hello
Is it possible to use an external library in a Javascript Ext? If yes how?
Best regards
Daniel Botelho
Hi dbotelho,
Yes it is possible to use an external library in a position of Javascript
In accordance with the procedure, this is where it becomes more difficult. It really depends on how the external library is distributed. Is the compiled code, or it's a library of compilation and a cod file?
If its compiled code, the answer is easy, you simply run it through the auditor before first and then include it in your extension.
If it is a pot of the compilation, you must specify it in your library.xml like so (stolen from the BBM extension) as a dependency. In this way it will be compiled with but not included. Then, you must load the cod library file as well as your application on the device.
blackberry.bbm.platform.BBMPlatformExtension She's the one

IPhoto library is locked and 'force quit' or restarting solves the problem. Any ideas?
iPhoto has error message: library is locked. clicking on repair or force quit or restart has not resolved. How can I get the app to restart?
Can you give us the exact error message? Generally, the most common one said something on a disclock. Is your library on an external? If so, what format is it?
Also, what version of iPhoto?
Assuming that is not on an external, try to download iPhoto Library Manager and use the rebuild feature. (In early versions of the Library Manager, this is the file-> control Rebuild. In versions later it is under the menu library.)
This will create a completely new library. It will then copy (or try) your photos and all associated metadata and versions to this library and as close as possible to what you had in the damaged library fix it. It does this based on the information it finds in the iPhoto sharing mechanism - but it means that things not shared won't be there, so no slide shows, books or calendars, for example - but it should recover all your events, albums and keywords, faces and places.
Because this process creates a completely new library and does not change your old, it is non-destructive, and if you are not satisfied with the result, you can simply go back to your old.

"Lack of function external lvanlys.dll ' when executing EXE
Windows 7 x 32, LV2009SP1 / LVRuntime 2009
I am trying to build an EXE from a customer code. They use the analysis library (NI_AALBase.lvlib).
It works well on my dev machine. When I create the EXE file and place him on a target with LVRuntime on that machine, I get the error:
Lack of function external lvanlys.dll: Mean_head:C NI_AALBase.lvlib:Mean.vi.
I explicitly added the lvanlys library to the project. I added the library as a source file in the build. Finally, I added the DLL itself to the project and as a source for the build.
Still the same error. The DLL is located in the folder data after construction. I tried to move it in the same folder as the EXE file and in the system32 folder. Nope.
I just changed the extension of the DLL to dllx and tried again, and I get the same error, so it looks that it can't find it.
Do I need to register this DLL or something? Is there a file?
You are an installer of construction or simply transfer the executable file?
If you are just transferring the executable file, make sure to include the folder "data" beside him.
(You can also check if the target computer has the engine execution of std (~ 170 MB) and not only the minimum (38MO).)

App builder includes library dll
I am trying to build an exe application in LV6i. I have problems with a couple of dll, which is ours and the other a library NIDAQ dll, lvdaq.dll.
App builder includes support files and wants to put them in the data directory. I want that they in a common space, because other applications use.
If I leave them in place, the build fails (probably due to a source/destinationclash).
If I move the source location, the App Builder won't find them unless I'm recording with them. I can't change the field of generator of the app it here to point where I want to.
If I register with the location of the 'source', I modify the destination location for what I want and the build succeeds, but the program cannot find the dll files and does not start correctly. I have manually pointing them at startup.
I am doing something stupid? (my head spinning) I'm very happy for App Builder just ignore them and install them manually on the target computer.
It works fine when running in the environment of development (base) of the screw.

If you want Builder app for ignoring them you prefer to copy in the path system or Windows and delete all other copies on your development computer. You will ignore the DLLs located in one of these locations by Builder app as being provided by the system.
Of course, in order to start your application on another system, need to ensure that these DLLs are installed. They can either go to the Windows directory or system referred to above, or if you put them somewhere else you must make sure to add this directory to the PATH environment variable. LabVIEW will simply Windows for the DLL, and if it isn't in the Windows directory or system (or the directory of the current application) or in a directory path variables windows won't be able to find it.
I would not mess with lvdaq.dll. It is necessary to LabVIEW for hardware access DAQ and access the system will install the NOR-DAQ drivers.

Library Cache lock when re-register a XSD
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production PL/SQL Release 11.2.0.3.0 - Production CORE 11.2.0.3.0 Production TNS for Linux: Version 11.2.0.3.0 - Production NLSRTL Version 11.2.0.3.0 - Production
If I 'use' a xsd in a single session, and then if I try to re - register the xsd in another session, the session of re - record indefinitely waiting on a library cache lock:
"use" the xsd is one session: create or replace procedure sp_schema_validate_xml(pi_xml IN XMLType, pi_xml_schema IN VARCHAR2) is v_count number; v_err_msg varchar2(4000); v_xml xmltype; begin --do level 1 schema validation if pi_xml.isSchemaValid(pi_xml_schema) = 0 then --level 1 vldtn failed. do level 2 begin --do level 2 vldtn v_xml := pi_xml.createSchemaBasedXML(pi_xml_schema); v_xml.schemaValidate(); end; end if; end sp_schema_validate_xml; / create or replace directory pipedoc as '/home/oracle/testfiles/HUD/ERS_HUD_VM01/PIPE'; begin sp_schema_validate_xml(pi_xml => xmltype(bfilename('PIPEDOC', 'DecryptedFile-36805759.xml'),0), pi_xml_schema => 'PIPE/Power/V4.0/PIPEDocument.xsd' ); end; / Now try to re-register the XSD in another session: create or replace directory XSD as '/home/oracle/testfiles/HUD/ERS_HUD_VM01/PIPE/XSDs/Power'; create or replace function f_exists_xsd(pi_list_item IN varchar2) return boolean is v_count pls_integer; begin select count(1) into v_count from user_xml_schemas where schema_url = pi_list_item; if v_count = 0 then return false; else return true; end if; end f_exists_xsd; / declare v_xsd varchar2(100) := 'PIPE/Power/V4.0/PIPEDocument.xsd'; begin if f_exists_xsd(v_xsd) = true then dbms_xmlschema.deleteschema(v_xsd, dbms_xmlschema.DELETE_CASCADE_FORCE); end if; dbms_xmlschema.registerSchema(schemaURL => v_xsd, schemaDoc => xmltype(bfilename('XSD', 'PIPEDocument.xsd'), 0), local => TRUE, genTypes => FALSE, genbean => FALSE, genTables => FALSE, force => FALSE, owner => user); end; / The session which is trying to re-register the XSD will wait indefinitely with a "library cache lock", regardless of whether the other session issues a commit or not. The lock only gets released when the other session disconnects. I consider this to be an Oracle product defect but of course we'll have to workaround this because Oracle Support hasn't been forthcoming with help recently.
I found a query previously that helped identify the blocking session so that we can complete the process:
select distinct ses.ksusenum sid, ses.ksuseser serial#, ses.ksuudlna username,KSUSEMNM module, ob.kglnaown obj_owner, ob.kglnaobj obj_name ,lk.kgllkcnt lck_cnt, lk.kgllkmod lock_mode, lk.kgllkreq lock_req , w.state, w.event, w.wait_Time, w.seconds_in_Wait from x$kgllk lk, x$kglob ob,x$ksuse ses , v$session_wait w where lk.kgllkhdl in (select kgllkhdl from x$kgllk where kgllkreq >0 ) and ob.kglhdadr = lk.kgllkhdl and lk.kgllkuse = ses.addr and w.sid = ses.indx order by seconds_in_wait desc
My question is twofold:
- The query above works only on instances that had put 10 gr 2 and not on those that have been built in charges on 11 GR 2 as apparently tit x$ kgllk view and related synonyms are removed in 11G (see Oracle support Doc ID 878623.1).
- Even if I can find other views to use, I don't like the thought of my deployment/upgrade script, through "blindly" to kill a session in order to succeed in restoring the XSD.
How can I do for correctly locking and releasing the XSD to avoid library cache lock? If not, is it possible to clear the cache of library?
Hmm - I think I myself have solved taking into account something that Odie_63 or Marco Gralike had mentioned earlier...
I modified my diagram procedure to release all resources to validate and I no longer get the library cache lock:
create or replace procedure sp_schema_validate_xml(pi_xml IN XMLType, pi_xml_schema IN VARCHAR2) is v_count number; v_err_msg varchar2(4000); v_xml xmltype; begin --do level 1 schema validation if pi_xml.isSchemaValid(pi_xml_schema) = 0 then --level 1 vldtn failed. do level 2 begin --do level 2 vldtn v_xml := pi_xml.createSchemaBasedXML(pi_xml_schema); v_xml.schemaValidate(); end; end if; dbms_session.modify_package_state(dbms_session.free_all_resources); end sp_schema_validate_xml; /

Now I wonder how to reduce library cache locks
Can be more (currentyl 50) session_cached_cursors approach?Hello
Please share us with AWR report for 1 h. frequency and show us the load for this profile.
Also check
SQL > show parameter cursor_sharing
SQL > show parameter sessio_cached_cursor
SQL > show parameter optimizerIt looks like not to suffer from analysis which is originally high library cache lock event. Yes sometimes increase session_cached_cursor helps us to reduce the soft analysis. But you need to check if its soft or hard analysis.

Hello
In our 11.2.0.1, database of production that we get an error ORA-00060 deadlock detected every day;
I know that the application must be tuned to solve this problem, but I want to troubleshoot errors using the app guys. When you look in the error in trace files,
I see it; LIBRARY OBJECT LOCK and the object is a sequence, an idea what is the cause of this?
SO: 0x5f3b460e8, type: 74, owner: 0x5fe7216e8, flag: INIT/-/-/0x00 if: 0x3 c: 0x3 proc=0x5ea473d38, name=LIBRARY OBJECT LOCK, file=kgl.h LINE:8349 ID:, pg=0 LibraryObjectLock: Address=f3b460e8 Handle=f5d8bd30 Mode=N CanBeBrokenCount=1 Incarnation=1 ExecutionCount=1 User=fe7216e8 Session=fe7216e8 ReferenceCount=1 Flags=[0000] SavepointNum=4e244349 LibraryHandle: Address=f5d8bd30 Hash=e3516ae5 LockMode=N PinMode=0 LoadLockMode=0 Status=VALD ObjectName: Name= SELECT SQ_MON_08877.NEXTVAL FROM DUAL FullHashValue=62542638cb895b30579930c3e3516ae5 Namespace=SQL AREA(00) Type=CURSOR(00) Identifier=3813763813 OwnerIdn=51 Statistics: InvalidationCount=0 ExecutionCount=41554 LoadCount=2 ActiveLocks=7 TotalLockCount=16369 TotalPinCount=1 Counters: BrokenCount=1 RevocablePointer=1 KeepDependency=1 KeepHandle=1 BucketInUse=0 HandleInUse=0 Concurrency: DependencyMutex=f5d8bde0(0, 1, 0, 0) Mutex=f5d8be58(0, 68797, 0, 0) Flags=RON/PIN/TIM/PN0/DBN/[10012841] WaitersLists: Lock=f5d8bdc0[f5d8bdc0,f5d8bdc0]
OK, so, the deadlock graph shows event you have two sessions involved in the deadlock on TX enqueues, each inmate to 'X' mode and waiting on ' mode.
Now, every session executes an insert statement:
INSERT INTO DeviceVariable VALUES(:1, :2, :3);
Then, because it's an INSERT statement, it can be a wait ITL. The only other possibility is a dead end due to cumulative values PK or UK. So what happens, is that each session trying to insert some values that the other session has already been inserted but not yet committed.
The solution is to return to the application logic.
Hope that helps,
