Is it possible to get the element data type of a Queue from itself?

Hi everyone,
i have a Q that has a cluster as element data type.
now when i want to enqueue
i'll use bundle-by-name
and for that i'd have to have my data-type present
(long cable from whereever (possibly from where i obtained the Q).
my question is,
whether there is a method/property-node/something that allows me to
wire the Queue Refnum into it and receive the element-data-type,
so i can then input into the top of bundle-by-name?
(i really dont want to have that cable all over the place)
the reason i ask here is that
the help for the outgoing Queue Refnum from the Obtain Queue method,
shows the element-data-type and so i hope there might be a solution.
thx for your time
and cheers

Solved!
Go to Solution.

If I understand your question correctly, the answer is "Yes, it's very easy ..."
The answer is "Preview Queue".  Here I create a Queue of some mysterious type (it's a cluster having a Thing and a Center, but you don't know that yet).  I take the Queue reference from whereever I can find it and pass it into Preview Queue Element.  I take the output and use it to define my cluster in Bundle by Name.
Two caveats.  This copies the first element of the Queue into the cluster, so you probably need to be sure to define all of the elements of your cluster.  But what if the Queue is empty (as mine is, above, as I just Obtained it) -- well, that's why 0 is wired into the TimeOut input, since I do not want to wait "forever" (-1) for the empty Queue to have an element!  Turns out that even in this case, you still get the correct Cluster elements!
Neat, huh?

  • Cannot get the correct data type in Oracle JDBC

    Dear ALL:
    I used JDBC ResultSetMetaData to get the column data type for Oracle Database. I created a table including 2 columns AAA, which is NUMBER type, BBB which is FLOAT type.
    However, I found a problem that either NUMBER or FLOAT data types are reported as NUMBER type in JDBC.
    IN SQL 2000, it is okay. SMALLINT, INT, TINYINT, etc..can be reported correctly.
    Can anybody tell me that what's wrong here? I will be very appreciated.

  • Is it possible to get the raw data?

    Hi,
    I am trying to do a program that sends to a server the data captured by a webcam, but I need to send it with java sockets.
    How can I get the raw data from a DataSource to send it myself?
    Thanks

    Hi
    It is absolutely possible to get the data - anyone you have in your org with basic SQL skills can move the data off to a standalone SQL server. This could be done most simply by backing up and restoring the DB using SQL Enterprise Manager.
    Moving the CAR/ART reporting tool would be more difficult... if you do actually use that for reporting (most people find it doesn't do what they need and don't use it for anything but basic troubleshooting, and get a third party package) then the best option may be to keep your publisher (possibly assigning it a new IP) and leave it running for as long as you need reporting.
    You would then need a new server to run your upgraded V6 CCM; you may find you need this anyway.

  • Is it possible to take the CDR data from a v4.2 Call Manager and copy it to a separate server where it would be made available for reporting?

    Is it possible to take the CDR data from a v4.2 Call Manager and copy it to a separate server where it would be made available for reporting? We are not interested in migrating the CDR data to v6 because of the concerns it introduces to the upgrade process. Is it possible to get the raw data and somehow serve it from a different machine? (knowing it would be 'old' data that stops as of a certain date). If so, what would be the complexity involved in doing so?
    It seems like the CDR data lives within MSSQL and the reporting interface is within the web server portion of the Call Manager... that's as far as we've dug so far.

  • The return of the "Unexpected Data Type" error

    I've searched the forum and only found discussions of this from over a year ago, so either I'm a loner or this is rearing its ugly head again.
    I've got a project that I've been working on between two machines, both running AE 11.0.2.11 with the same plug-ins. One is a macbook pro, one is a macpro. Both are running 10.6.8 (I believe that's snow leopard). I've been saving the project files and assets to the dropbox folder on my machines so that everything is always in sync between them. ***It's been working flawlessly for months.*** I haven't updated anything recently, other than installing Adobe Acrobat on the desktop machine a few days ago.
    This morning on my desktop machine, I couldn't get the project to open without getting the "unexpected data type" error. Holding down shift did nothing. I instinctively started a new project and imported the .aep I was trying to open. No errors! Then I tried to change work spaces and the error came up again. I hit caps lock and tried again. No go. At one point the workspace drop-down had bullets next to *two* of the workspaces, as if they were both active simultaneously.
    My workaround for the moment was to go to my dropbox on the website and revert to a previously saved version of the same project (thank *YOU* dropbox) from a few days ago. That opened fine, though it's missing a few hours' work.
    My fear is that this will recur and I will have to keep going back in time to keep working (two steps forward, one step back) and I've got a deadline to meet. I will try to stay away from custom workspaces, as one poster to this forum says they are generating that error in CS6 (no helpful replies to that thread).
    Anyone else experiencing this in 2013? Any ideas? All help is much appreciated.
    AE CS6 11.0.2.11
    Mac Pro OS v 10.6.8
    Processor:  2x 2.66ghz dual core intel xeon
    12Gb 667mhz DDR2 RAM

    I just started getting the same error today. Never would've imagined workspaces would have ANYTHING to do with this. But I just went to workspaces and clicked 'reset workspace' for whatever I was on, reloaded the project and no error. WTF Adobe??

  • Data recovery, possible to get the file structure back as well?

    Hi Apple Smarties,
    I closed my laptop lid on my external LaCie drive without ejecting the drive first (smart one!). After that the external drive wouldn't mount. I've used Data Rescue 3 to recover all the files from the drive... however it's just lumping all the files into one big batch :-( ...anybody know if it's possible to get the files into the correct files structure they were at before the drive got corrupted?
    Assistance would be HUGELY appreciated.
    Many thanks
    Kind regards
    Doug

    Thank you Barry. Yes, Comcast is my mail provider. It is a POP account.
    Now, if you could point me in the right direction to do that re-build, I would be ever so grateful. I did use the "rebuild" button on the Mail tool bar for that box and it did not help. Perhaps there is something else I could do?
    As I mentioned, I am very new to the Mac world, and I get a little lost. Well, at age 73, I guess that's not hard to do! Been on Windows forever so lots of the terminology in Apple is quite different for me.

  • Is it possible to get the updated table records based on date & time.

    Is it possible to get the updated table records based on date & time in oracle.
    Thanks in advance.

    no, actually i am asking update records using 'UPDATE
    or DELETE' statement, but not insert statement.
    Is it possible?
    I think we can do using trigger on table, but problem
    is if i am having 20 tables means i have to write 20
    trigger. i don't want like this.Of course it's still possible, typically you'll find applications with a column LAST_UPDATE, probably a LAST_UPDATED_BY and so on column. You don't say what your business need is, if you just want a one of query of updates to particular records and have a recent version of Oracle, then flashback query may well help, if you want to record update timestamps you either have to modify the table, or write some code to store your updates in an audit table somewhere.

  • Is it possible to view/get the table data from a dump file

    I have dmp files generated using expdp on oracle 11g..
    expdp_schemas_18MAY2013_1.dmp
    expdp_schemas_18MAY2013_2.dmp
    expdp_schemas_18MAY2013_3.dmp
    Can I use a parameter file given below to get the table data in to the sql file or impdp the only option to load the table data in to database.
    vi test1.par
    USERID="/ as sysdba"
    DIRECTORY=DATA

    SCHEMAS=USER1,USER2
    LOGFILE=user_dump_data.log
    SQLFILE=user_dump_data.sql
    and impdp parfile=test1.par.

    Hi,
    To explain more about my situation.
    Target database has the dump files, where as the source database (cloud) doesn't have access to the target database.
    However, I can request the target DB DBA team to run the par files and provide me the output like a SQL file which I can take and run it in my source database.
    I got the metadata the same way, but is there any way I could get the data from the dump files on the target DB without actually accessing it? My question might sound weird, but please let me know.
    <
    1. export from the source into a dumpfile. You can do this on the source database and then copy the file over to your local database or you can do this from a local database if you have a database link defined on the local database that points to the source database.  In the second case, your dumpfile will be created on your local database.

    How can i access the dump using the database link?

  • How to get the current date in standby display?

    My N73 ( 3.0705.1.0.31 ) displays the current date/day only in the general profile. When I switch to any other profile, that place is taken over by the profile name.
    Is it possible to get the date/day displayed in a non general profile?
    If it is otherwise, the 240x320 display is of little use...

  • Hi, can you help?  My emails that I have received show the date received as either today, yesterday or July 28.  How can I get the correct date received?

    Hi, The emails that I have received show the date received as either today, yesterday or July 28.  How can I get the correct date received?

    That's very scary. They might do it, but I personally have never had Apple contact me re id's except on their site when signing in. I suggest you DO NOT respond until you have a phone conversation with Apple security. They can verify if they sent you the e-mail and why.
    While it's very possible it's true,again, I suggest you not respond until you speak to someone at Apple. I've often read here that when people sign in they are not allowed to because "someone else has used the id" type of statement.
    Also, you should be able to go to the app store and see what apps you have downloaded.
    Though it could have been a free app, have you checked to see if any were bought with your id account?
    I've gotten these types of e-mails from places like USPS and FedEx which look amazingly authentic and were from their website. I also received an odd e-mail from my cousin in Ireland last year that clearly was not from him. It was also sent to others in his family in Ireland. I e-mailed him that I only opened it because it had a .ie, but suggested he change... Days later I received mail from 'him' - same name, but at yahoo.com. 
    Again, I would call Apple. You can also report it at [email protected], but I would not settle for that given your situation. If nothing else, call Apple sales (sales depts. anywhere answer fast) and ask them to transfer you to security. Apple will not want anybody accessing their name, and while it's unlikely, it's not impossible that it is someone phishing.
    Hope this helps and can you let the support community know your results by posting on this thread when you're done? Thank you.
    Hope this helps.

  • Compare the elements data of the 2 context nodes using internal table

    Hi,
    How can i compare the elements data of the 2 context nodes using internal table?
    Regards,
    Ronita

    hi ronita,
    just get the nodes data into internal tables and just compare them......
    node1->get_static_attributes_table(importing table = ITAB_node1)
    node2->get_static_attributes_table(importing table = ITAB_node2)
    now u have the data of ur 2 context nodes in 2 different internal tables ..
    just compare them like
    if  ITAB_node1[ ] = ITAB_node2[ ].
    write: / 'itab1 is equal to itab2'..
    endif.
    and u can use as many as comparision operators between these 2 tables to compare them....

    Programming of additional columns (Customer Exit)
    You can use Customer Exit M61X0002 to program up to three columns for the individual line display and the period totals. These columnscan be filled with additional data, which you can call in the lists using pushbuttons.
    Programming of customer-specific access to the lists (reports)
