A new database explorer project

Hi folks!
I've planed to write a new "database explorer" firtly I mean to use this project in my Java Developer Certification Exams, after(or before) I want to open the source and have another database explorer in the open source world. :)
My firts ideas are around a different way to implement some things. I've seen few tools wich use the power of JDBC that abstract a lot of things for us, to retrieve the metadatas of a given database, but I want to implement a plug-in concept cause different databases have different resources/features and I want go so deep into these features.
Then these plugins would implement those features, for example postgre has some tuning/performance resources that we don't have in firebird neither in oracle, and we have sequences in oracle and itsn't present in other databases.
My question is if someone could point me some stuff to help me project this plug-in architecture? and is these kind of project a good option to use in the Java Developer Certification Exams?
Thanks
Leandro

Visual Studio Community 2013 does not show database explorer

I am a Newbie who wants to learn web development. it seems in older version of visual studio, when you add a database item in solution explorer there is a database explorer.
but now in my visual studio 2013, if i add a database item, there is no database explorer to let me browse table or others below. Why? I installed SQL express and Visual Studio on windows 8.1 x64
Also any pointers to free tutorial on the internet that lets me learn and practise working with database in a web application?

Hello Lenny,
Can you see Server Explorer in your VS? What about show us a sceenshot so that we can understand your problem.
I do not have VS 2013 Community right now but in my point of view you should have related components. I will also install VS Community later and share you some info.
Best regards,

SSMS crash when creating new database diagram

For several years I have been unable to create database diagrams from within SSMS. I have tried every combination of VS2005, VS2008, VS2012 and VS2013 with every combination of SQL2005, SQL2008, SQL2012 and SQL2014.
I have installed, uninstalled, and repaired many dozens of times. I am currently using VS2013 ultimate with SQL2014 express.
I have tried every related 'workaround' that I can find on the internet. Still the problem persists.
Any help would be deeply appreciated.
Here are the relevant details with file versions:
In SSMS, I right-click on a database and choose New Database Diagram. A Blank diagram window appears with the SSMS error dialog:

Creating a new database

Ok new to Sun JSE8. How do you create a new PointBase database? Do you have to have PointBase installed on you PC? or is it installed with JSE8? I have a application that was prototyped in Access and now we are going to do it in Java. This is a school project that we are working on but it will be used when we are done creating it. I looked in the help file but could not find out how to do it. I have used MSSql alot and can create a database there and then connect to it but we were trying to get away from MS products a non proft will be using our program and the cost of MSSql would be to much.
Is everything done by code only for creating a new database and tables?
Thanks

Pointbase comes bundled with JSE8.
To create new pointbase database:
Go to the following directory under your JSE8 installation directory:
For example:
\jstudio_ent8\AppServ8.1UR2\pointbase\tools\serveroption
Use the startconsole file to start the pointbase client console.
The pointbase GUI will come. This has the option to create new database by going to the pointbase console menu. Also, remember to start the pointbase server before. You can start it from the IDE, by going to Tools -> Pointbase Database.
Also, the following sample databases are installed with the Pointbase installation:
sample
sun-appserv-samples
To connect to the Pointbase sample database, you can check the IDE help online. Simply search for pointbase.

PS2013 - When creating a new instance of Project Server hangs in 'Waiting for resources' status

Hi,
I have one instance of Project Server 2013 fully operational and I tried to duplicate the instance to make some tests. As I know the issue of using the same Content Database of Project Server in the same Server Farm, I used the powershell backup/restore/dismount
and mount the content database to change the site IDs to avoid index duplication. The Project server database was a regular SQL backup and restore in another database.
I created a new Web App in the port 90 as show below.
Then I included the Content database of Project Server as separated DB from SharePoint for this new SharePoint -acme90 and I tried to create the new instance. The creation hanged in "Waiting for Resources" status.
To make another check excluding the reuse of the SharePoint-80 I tried to create another instance both in the SharePoint-80 where is the working instance and in the SharePoint-90, everything default and again they all hanged in Waiting for Resource.
If I try to create the instance using PowerShell I got the following error:
PS C:\Users\epm_setup> Mount-SPProjectWebInstance -DatabaseName Test_EPM -SiteCo
llection http://acme02/epm -Lcid 1046
Mount-SPProjectWebInstance : Cannot find an SPSite object with Id or Url:
http://acme02/epm.
At line:1 char:1
+ Mount-SPProjectWebInstance -DatabaseName Test_EPM -SiteCollection

   PSCmdletMountPwaInstance) [Mount-SPProjectWebInstance], SPCmdletPipeBindEx
ception
    + FullyQualifiedErrorId : Microsoft.Office.Project.Server.Cmdlet.PSCmdletM
   ountPwaInstance
All SharePoint and Project Server services are running, all App Pools and sites are started at the IIS. I could not find a hanging timer job.
I cannot stop the hanged process or dismount the instances using Powershell since no instance created.
How should I solve the hanging status of creation of the instance? As they are in Hyper-V I can go back using one snapshot.
Thank you.
Best regards, Ricardo Segawa - Segawas Projetos / Microsoft Partner

Hi Eric,
Thank your for your interest in this case.
I checked for running and crashed PWA jobs and deleted all of them just after restoring the snapshot and tried to create the new instance in the new web app in port 90 (besides the existing and working instance in port 80), but again it hanged in "waiting
for resources". There is not any timer job hanging, no error in event viewer or in log. So the error is well before working with cloned dbs.
Answering your questiion, I am working all on 2013. My intention is backup one instance of the port 80 and copy to the instance of port 90, changing of course the url and the index of the content db of SharePoint. The process I used was:
Create a new web app in port 90, creating a new SharePoint_Content_2 on a
http://server:90 site.
Created the top level site called Portal using the Team Site template.
Create a new content db for new instance of Project Server named EPM_Content_2 using Central Admin.
Backup content db from port 80 instance of Project Server and restore to this EPM_content_2 using PowerShell cmd.
Dismounted and mounted this Project Server content db to create new index for existing sites to avoid index conflicts.
Backup the Project Server DB from port 80 using SQL backup and restored as ProjectWebApp2 db for port 90 instance.
Tried to create a new instance of Project Server
http://server:90/pwa on web app of port 90 using the ProjectWebApp2 db and using the same app pool of the other instance. But as in the previous case, it hang out in "Waiting for resources".

Can't create new iMovie 11 project

When trying to create a new iMovie 11 project, I get a dialogue box with the following, "Cannot create project. Please check the disk to ensure there is enough free space and you have permission to write projects." I have a 2009 Macbook Pro, am running OS X 10.8.2, and have 316 GB of free storage space.
Based on what I read on previous threads, I did the following (not necessarily in the order listed):
I selected the iMovie icon and "Get Info" under the File menu and changed the setting to indicate that I have "Read & Write" permissions for the system, wheel, and everyone.
I went to the finder, selected the "Go" menu and held down the option key to open the "Library." Under "Preferences," I selected "com.apple.iMovieApp.plist" and deleted it.
I restarted the computer.
After numerous attempts with the above, I reinstalled iMovie and repeated the same steps.
Still no luck. Am I going about this incorrectly? Is there something else I should be trying?
Thanks in advance for any assistance!

I had this same issue after installing Flash Builder 4.5 for PHP and Zend Server CE. I installed as admin but the document root (/usr/local/zend/apache2/htdocs) did not have the admin user with Read & Write permissions.
In case it helps others, this is how I got it working:
Opened Terminal and typed:
defaults write com.apple.Finder AppleShowAllFiles TRUE
killall Finder
I could then see the hidden /usr/local/zend/apache2/htdocs folder. I right-clicked it and selected Get Info. Under Sharing & Permissions I then added the admin user with Read & Write privileges.
To return Finder back to not showing hidden files, issue the same commands but with FALSE.
It might be worth investigating how to configure Zend Server CE so that the document root is not in a hidden folder. Flash Builder for PHP will let you explore your output folder in the Package Explorer, but you will need to have hidden files visible to see them in Finder.

How to create a new database and use it?

Hi there,
I have so many tables in the current database that i'm working on. When i start to create a new table such as employee, student, person...etc it doesnt allow me to create them becuase it says the tables exists. Even when i use the drop command to drop the tables, doesn't help. So most of the time i have to create a table with postfix of 1, 2 to the table name.
Therefore i need to create a database for every project that i do.
How do i create a new database?
Then how do i use the database that i just created?
Then how do i find the out whats the database that i'm currently working on?
Thanks!

A database is a physical set of files that contains many schemas. Each schema has a one to one relationship with database users, so to create a new schema you create a new database user.
e.g.
CREATE USER fred IDENTIFIED BY fredspassword;Then, by logging on as fred you can create all the new tables you like as that user, in that users schema.
If you create a new database then you will find you cannot access functions/procedures, packages, tables etc. that exist in another users schema without creating a database link to the other database that contains them.
If you just create a new schema, you can more easily get at other users schema objects (tables, packages etc.) by referencing them with the users name e.g. JOE.TABLE1 providing that user has given permission for your user to access them. You can also create synonyms that allow you to reference other users schema objects as if they exist in your own e.g. you can have something called TABLE1 in your own schema that is in fact referencing JOE.TABLE1.

Running resports from new database using discoverer desktop

Hi,
I am new here on the project and dont have much documentation avaialable. I have is just passwords.
I am new to discoverer. I see that there is one historical database names as HIPRD which has historical HR information of audit purpose(just database , no EBS apps). all users who uses HIPRD database they have user_id as database schema.
the way usres uses data from HIPRD database is either through disco desktop or they launch disco viewer. So they login in disco desktop as username/password database name untick oracle application user. once they login they see all folders where they hace access to run reports.
I created new database called TEST using cold backup set of HIPRD and i have upgraded to 11gR1. I have updated my local tnsnames.ora with TEST entry and i am able to connect TEST(11g) which has same data as it is available in HIPRD.
My question is what I have to do on disco side so that usres can run reports from upgraded 11g TEST database using disco desktop or disco viewer the way they are doing for HIPRD.
Please help, I am new to discoverer

please i need help

Created new Database in OTM

Hello,
I've created new database in OTM application. After a hard time, it was succussfully done. unfortunately, one issue is still pending and am not able to re-solve that. once i logged into the application, i got an error 'syntax error - ...otm/treeview.do". when i open this link that was not system founded that was actually shown me an apache error. and on the right panel loading page was coming contineously.
I've done the ODBC config and the database config too..Also checked the server name and other details but still not able to solve this issue
can anyone help me on this?

Hi
Can you confirm that the relevant tables have been created in Oracle.
Version 8.50 uses 2 databases one (an Access database) to log in and the second (Oracle in your case) to store project related information.
I think that the issue that you are seeing is due to the oracle database not being created properly.

Crash while creating a new cRIO FPGA Project

When I want to create a new cRIO FPGA Project with the wizard, Labview freezes and crashes ("Labview 8.6 Development System had stopped working".) The wizard discovers my cRIO-9073 Integrated controller, but when it's trying to discover the CompactRIO chassis, the program freezes and automaticly shuts down.
In MAX, there is no problem in discovering the FPGA-chip in the cRIO-chassis (RIO0)..
I tried to use the new FPGA project wizard in Labview 8.5. While searching for the cRIO chassis, the program doesn't freeze, but says that the cRIO-chassis cannot be found..
When I manually want to select the chassis, I can only choose for the cRIO-9072 and cRIO-9074. There is no cRIO-9073-icon.. ?
What am I doing wrong, or is it a bug ?
Regards,
Kenneth

Hi JMota,
Thanks for your quick reply.
I'm using Vista Home Premium SP1 32-bit. And I have admin privileges. I'm the only user of the computer.
I've installed NI-RIO 3.1 on the pc. So it's the same version as on the controller.
When I try to add the controller and chassis directly from the Project Explorer, then I have the same problem.
The program freezes while it's trying to discover the chassis..
I'm able to select the cRIO-9073..
But in the second step, the program freezes when it's trying to discover the chassis..
When I try your second method, the same problem occurs.
I manually selected the specific controller (RT CompactRIO target), with the chassis (cRIO-9073) and the integrated FPGA-chip (RIO0), and at last the NI-9472 DO-module in slot 1.
Then, I've changed the IP of the controller from 0.0.0.0 into the IP assigned in MAX 192.1681.3.
When I click on connect (right-click RT CompactRIO target - connect), the same story.. Program freezes and eventually shuts down.

New Database Design

Hi,
I'm an DBA and i was assigned to design a new database(fresh) in oracle 11gR2 in windows platform for a project. Since, i'm new to database design, getting confusion on what perspective to approach and where to begin.
Can anyone please help on this.
Note: URL's are welcome.

Hi,

The link that you sounds good and providing much info on considerations in creating a database and schema security.
But, i want the logical design part.
Assume that the database design for College Management System. It might have enrollment module, result module, staff module, etc., including more schema objects. I'm expecting the procedures or steps involving in such designs & how to design.
It starts with interviewing the end-user and determining their requirements .. especially flushing out all the entities (student, staff member, department, course, class, etc, etc, etc) and their attributes, then determining the relationship between said entities and attributes. Those entities, attributes, and relationships will be your logical database design.

HSQLDB in Eclipse's Database Explorer

In Eclipse's Database Explorer view, is there any way to get an HSQLDB or a generic database manager? Right now, when creating a New Connection, when it asks to "Select a database manager", it only gives options of DBs like DB2, Derby, MySQL, Oracle, and others...
If I'd like to use HSQLDB, how can I do so? I wouldn't mind using a generic Database Manager, but there's no generic option and one option must be selected! There's no way (at least based on what I've tried) to go without selecting a Database Manager.
Some really weird things show up when I connect, after entering the correct connection information but under an incorrect Database Manager...for example, in DB2, I see things like INFORMATION_SCHEMA, with a large number of tables underneath it...which only serves to confuse me...
I doubt that there's no support in the Database Explorer view for any JDBC database.
Any information on how I can use HSQLDB in Eclipse's Database Explorer would be greatly appreciated.
Thanks.

Derek,
you can get the Database Explorer with Eclipse updates. its just a regular eclipse plugin, not a cr4e one.

New Open Source Project - Java, Struts, EJB

There is a new open source project called Centraview. This is an open source CRM/SFA application which can provide a business a full view of their enterprise from lead generation, sales, contact management, project management and integrate into accounting. The development has been going on for more than a year now and they've now taking this open source, so there is alot of opportunity for Java developers to get involved with project that really takes advantage of Java technology. The system is built on the Struts framework and utilizes JBoss as the EJB container, the back-end database is MySQL although there is some initiatives to look at DB abstraction. Anyway here's the link:
http://sourceforge.net/projects/centraview/
Anyway I decided after examining Centraview, that we're not going to be building our own, but using Centraview and it's nice to know we can take part in development and understand the inner workings, so we never limit ourselves.

Presumably you mean GUI and not web.
I have used AutoIt to drive GUI window applications.
[http://www.autoitscript.com/autoit3/]
Seemed pretty easy when I used it. It had a recorder.
On windows I believe you can also use "script host" and the newer powershell but I have used those.
You could also look at the java Robot class or whatever it is called.

Connection problem with new database

Hi

while connectting as sys user error
ORA-12500:TNS: listner failed to start dedicated server process
wlile connecting toad and sqlplus

Please read the error again "listner failed to start dedicated server process". Means what, listner listened your request to connect, it tried to hand-off the connect request but due to resources problem (lack of memory) it is not possible to start server process; i.e. presumably the server is very busy at that time. If you are not able to resolve the issue, please check the unwanted services and stop them in strat-run-services.msc.

New database connection failed with oepe

Hi everybody,
@http://docs.oracle.com/cd/E27086_02/help/oracle.eclipse.tools.common.doc/html/install.html#install_oepe
Oracle Enterprise Pack for Eclipse Installation Guide says:
"You can install OEPE using any of the following ways:
Download, and then unzip OEPE plugins directly into the Eclipse dropins folder and restart Eclipse."
This is what I have done,
then when I create a new database connection, and I press the button "test connection" i got a pop up saying "Ping failed" giving details:

The documentation is out of date. The unzip to dropins method is no longer supported. The OEPE zip you downloaded is actually an archived repository. You can follow the instruction for installing using Eclipse Update Manager and point to the downloaded zip instead of the online repository.
I will follow up to get the docs updated.
