JDeveloper 10.1.3.4: How to choose a database to connect to
For the experienced:I use JDeveloper 10.1.3.4 and have a question about the choice of a database server to connect to.
The application I'm developing used the database on an Oracle database server.
Now the exact database schema (that is, table definitions, constraints table, etc.) has been reproduced on a different server with a different name (the name of the schema on the old machine is ZB and is ZBDB on the new machine).
To try to connect to the database on this new machine, I created a new database connection in the window connections in JDeveloper. I stop and then again JDeveloper. The application is still running, but I don't know how to check in JDeveloper which machine it is connected to.
Then in the Connections window, I deleted the definition of the connection to the old machine and restart JDeveloper. In one of the entity objects context menu, I selected "synchronize with the database... "and you have to choose a connection. I chose the connection with the new machine and attached (I can tell because one of the pages shows less number of lines when it is connected to the old machine).
I then re-created the definition to connect to the old machine to see if I can choose to connect while the two database connections are present. I chose one of the entity objects to synchronize with the database, but this time I don't have to choose a machine and the message said that the selected objects 'don't need no synchronization ". So I stay connected to the new machine. To connect to the old machine, once again, I'll have to delete the definition of the connection to the new machine.
I also tried the "Connect" and "Disconnect" options in the right-click menu on the database connection in the Connections window. But that has no effect on which connection to use.
I think that there should be a way to choose and check the connection to a database. But I don't know how. Can anyone help?
Thank you!

Click the project icon properties or right-click on your model project of-> project-> business-> here components properties choose connection

How to choose a database schema to use for a file of sequence?
I have several database schemas on my TestStand system, and when I select a movie file that I need to position the schema for the results entered into the database correctly.
I use a SequenceFileCallback for DatabaseOptions in my file of sequence and in that, I set Parameters.DatabaseOptions.DatabaseSchema.Name = 'xyz', where xyz is the name of database schema to be used. It does not, and it reports an error that it cannot be loaded or the file is maybe damaged. This feature works, or should I just a mistake in what I put this equal to?Evan... It turns out that your last point: 'Make sure you use quotation marks around the name of schema, no simple markings as in your message.', has solved the problem. Funny it did not report a single error with the brands. Thanks for the quick response! PLF

How to choose an icon for a pinned tab?
I created a two pinned tabs. We have a very generic icon and the other has no icon. How to choose an icon for the pinned tabs? Can it be done? Using a hack is fine too.
You can probably do it with the code in the userChrome.css file.
Here is an example that works for Gmail.
Add code to the file userChrome.css below default @namespace.
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */ #tabbrowser-tabs .tabbrowser-tab[pinned][label^="Gmail"] .tab-icon-image { list-style-image: url("https://ssl.gstatic.com/ui/v1/icons/mail/images/favicon5.ico") !important; }
The file userChrome.css (UI) customization and userContent.css (Web sites) are located in the folder of chrome in the Firefox profile folder.

HP pavilion 15-e034tx: how to choose the right RAM for laptop
How to choose the right RAM for my laptop (Pavilion 15-e034tx). I know I should buy DDR3 ram.
Are there other factors should I consider when buying one? I got 2 slots for ram, which od these combos are possible?
1-4 + 4 GB
2-4 GB + 8 GB
3-8 GB + 8 GBThank you
From the Manual:
Two customer accessible/upgradable memory module slots
Support for dual channel DDR3L (1600 MHz)
Support 8192 MB RAM system in the following configurations:
8192 MB (8192 MB × 1, × 4096 MB 2)
See page 53 for instructions. Memory access is easy via the service Panel. This is the part number for the approved 4 HP concert module:
4 GB (PC3L, 12800, 1600 MHz) 691740-001
A 8 GB module is listed in the manual, and it's a 3rd generation of processor i5 I suspect 2 x 8 = 16 concerts would work, but strictly following the manual your only option is to add a 4 GB for a total of 8. Most users really not more 8 GB and adding a second identical module will allow two-channel operation, so you should see a noticeable jump in the overall performance.

How to choose the elements that are copied when using a custom template?
Hello
As the title, how to choose whether or not an element is copied into a new project when the project is created from a custom template?
I recently created a custom template by following these instructions, as had recommended after my last question on the forums:
The template was created so that I can create several versions of a broad program of LabVIEW with unique names (using the prefix in the project options). It works fine except that some things are not copied into the new project, even if they are part of the model. The most important point of "disappeared" is for runtime menu (which is a RTM file). Does anyone know why this might be missing? And how to make sure, it is included in the future?
Thanks for any help.
OK, here is the custom script VI (saved in LabVIEW 2012) and XML update that should fix your test project. You can take a look at how I implemented XML and script VI, then make the changes applicable to your current project.
1. use the attached file to MenuTest.xml for your meta data. Note the new sections CustomVIMode and CustomVIPath .
2 create a folder next to your .lvproj of the source script and place the PostCopyScripting.vi in there.
Once you have done so, your MenuTestProject should be copied on properly... the GTR will be present in the new Bachelor of LAW, it will have a correct prefix (if specified), and it will be the correct link to the VI.
I would like to know if you have any other questions or problems.
