Database manager for Java DB/Apache Derby?

Does anyone know a great and free database manager software with GUI for Java DB/Apache Derby where I can create and open databases? Something like Mysql Administrator and Mysql Query Builder for Mysql.
Thanks in advance!

I don't think there is any separation between CCMS and other systems, all use one database. If you use MaxDB use Database Manager, if smth like SQL Server or Oracle use standard tools of this vendors, like Enterprise Manager third party tools also helps you, cause I don't see any difference between

Database statistics for Java system in CCMS (RZ20)

Hi All,
We have configured CCMS for JAVA system, but unable to view the Database statistics like Tablespace size, Free space, Backup, Performance etc., for it.
We are able to see these statistics for ABAP stack.
Is there any possible method (or) class to view these statistics?
We have even created a new rule-based monitor with class CCMS_DB_mcmtc and CCMS_DB_space_mscl but in vain.
Even if we cannot view these in RZ20, do we have any other methods like Netweaver administrator or Introscope or some other means....?
Waiting for some help......
Regards,
Phani.

SMD database monitoring for Java MSCS cluster system

Dear All,
We have install SAP netweaver 7.0 EHP1 java stack on oracle 10.2.0.5 with windows 2008 R2 MSCS cluster enviornmant.
now we are configuring SMD
From SMD, while configuring Managed system(JAVA ONLY system)--> database monitoring I am getting following error
DB connection Id :%_SID_virtualhost_SAPSR3DB
Connectivity test :
Database history :This connection could not be tested, thus the DB performance warehouse was not set up

Tns ping command is also not working when we give host name as virtual host of JAVA system
but when we change it to phyiscal IP address of the cluster server it is working fine.
Could you please let me know any setting need to be done
Sincerely

Hi Paresh,
>> Tns ping command is also not working when we give host name as virtual host of JAVA system
but when we change it to phyiscal IP address of the cluster server it is working fine.
>> SQL error 12505 ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
Virtual hostname must be resolved on both hosts while configuring SMD. Otherwise you'll not able to access Oracle Listener.

Database Manager for Address Book

Help me! I seem to need to reconstruct my Address Book every time I change my PDA. the card formats are never quite the same....
To date, I have been exporting to text files, cleaning the text tile with MS Word, opening the text file in Excel - doing my clean up and reorganization in Excel - saving as a text file, then importing the text file back into Address Book.
Eh - and every time I do this, SOMEthing get screwed up. This time, I lost all the fax numbers!
Question: Is there a database manager that will open the AddressBook.Data file in native format, allow me to make global changes or individual edits and resave the native format - without needing to do all of the exporting and importing and data corruption?
Thanks for any feedback or comment!

maybe this solves your problem.
What PDA are you using?

Product Database Management For Manufacturers Web Site - How do I do this W/ Templates?

In short, I have an excell database of product. I am
developing a web site for a factory with many products. I have
never used a database to fill specific template data, except for
3rd party shopping carts...
So, how do create a database, upload it to the site, and
allow users to access product information? Looking for your typical
database to template set up with tags in specics spots withint he
HTML of the template that reference the columns of data in a
specific row of the database.
I basically need a shipping cart, but with no "BUY" or "VIEW
CART" buttons.
Thanks!

I'm not an expert on this but you need to know what sort of
server
you're going to be using. The server can drive what database
you're
going to use.
MySQL?
MSSQL?
Access?
There are others.
If you're on a PHP server you may want to stay with MySQL.
Talk to your
server admin to see what is installed. MySQL has a control
panel called
"Workbench" that can manage the database.
MSSQL uses Enterprise Manager to administer the database.
Whether it's MySQL or MSSQL, each will be able to import
data; same can
be said for Access. Access is probably the least flexible; in
other
words, it's not built for as high of performance but for
small sites
without a lot of traffic, it's probably fine. With Access,
you basically
build the tables and everything on your own computer and then
upload the
mdb file to the server.
Once you have the database, you can start to build a page in
Dreamweaver. The first thing you should do is pick your
server script
language VBScript, php, ... You then create a connection to
the
database. Once the connection is made, those tables become
available to
drag and drop on your page. From there you can do repeats and
form
columns of data to display products.
That's it in a nutshell.

Monitoring memory and thread management for Java 1.4.2_04

Hi,
I have an application which is using Java version 1.4.2_04. The application deployed in Customer site is having some memory issues. There are observing java.exe going 100% in Task Manager. The same application (of higher version)
uses Java 1.5 is not seeing any issues.
Now Customer needs the root cause of the issue and i would like to check the code which is causing the issue. I came to know we can monitor threads and memory using JConsole. Since we are using Java 1.4, i installed Java 1.6 on a remote machine and tried connecting to the problematic machine. But it failed to connect.
i have added the option "-Dcom.sun.management.jmxremote.port=8880" when starting JVM (this i have provided inside ServletExec batch file, ServletExec is my web server).
Any idea how to connect to the problematic machine from remote using JConsole. Or any other tools i can use on Java 1.4 to nail down the problem..
Please provide pointers.
I have another doubt on Java version 1.4, since there were many memory issues, am i hitting any defect in Java 1.4

Unless your company has a service contract with Sun you right now, can no longer insure that the VM will remain secure nor even really running.
See the following for the java VMs that you are using.

An abstract database api for java

hi there
does somebody know if there is something like this around - I mean, an API, that works with abstract objects like tables, fields, rows, where-conditions, joins and so on, and then automatically generates the appropriate SQL-statements ?
java.sql is a quite low-level and implementation dependent API, I'd be glad to see an abstracter framework. anybody seen something like that ?

JDO? Though it provides for more than just portable queries, and doesn't provide any of the niceness of something like the RogueWave DBtools.h++ in terms of being able to build up a query procedurally, but it's a big step..

Have you been able to resolve this yet? I don't have any reference to Oracle error codes but would suspect a quick Google of something like 'Oracle error code 997' should result in good information, since it is an Oracle error...
Hope this helps.

Database access tool for Java Development

Hi,
A couple of days back, our SAP's database (MSSQL) was corrupted and downed the Java Stack.
During the Java development, normally after a newly created table was deployed via Java Dictionary, Java developer will access the database via the MSSQL Enterprise Manager to view/delete/update data. Unlike the ABAP development, all database access was done via SE16 in SAPGUI. It was believed that the Java Development kind of direct access to the database via the MSSQL Enterprise Manager was causing some MSSQL tables to be corrupted, and thus downed the Java Stack.
1. Is there any tool like SE16 to access database during the Java Development?
2. If no, what kind of recommendation/tool to access database for Java Development?
Any help would be much appreciated. Thanks.
julius

Julius,
There are no industry recommended open source DB tools.
Normally it depends upon the developer preferences that how he/she wants to see the tool usability.
I can suggest you to go through the below link:
http://sourceforge.net/search/?type_of_search=soft&words=SQL+Tools
You can find many open source SQL tools, which you have to test and select one among them.
I can suggest you to use:
1) TOra
2) Easy SQL
3) SQuirrel

Migrate Database from MySQL to Apache Derby

Hello all,
Does anyone know how to migrate a database in MySQL to Apache Derby? Will ij do this, and if so, how do I go about doing it? If not, is there a way to do so?
Thanks in advance! -- BTR

Errr... Apache Derby is a database implemented in Java?
Sorry, I'll go somewhere else.

Database apache derby

Hi,
I configured and installed MOBI and used default apache derby as database. Is it a good database tool or should i migrate to other database like sql etc.?
please advise.
Arun

Hi Arun,
if you have more than about 5 concurrent users requesting information via BO Mobile you should change the database from derby to another supported one. Derby is only ment for small installations...

In-place upgrade of Enterprise Manager for RAC databases is not supported

upgrading 2 node RAC from 10.2.0.1 to 10.2.0.3 on Windows 2003 64 bit. I got the following:
In-place upgrade of Enterprise Manager for RAC databases is not supported in this release
Now I cannot log in to the database control as sys with sysdba role . I get "invalid username/password" error
I can login as a dba user
I also get a java error after I log in, some thing about class not found, but then I'm in and I can do everything that I try, although I haven't tried scheduling a backup yet
Can I upgrade EM to 10.2.0.3?
If so, how?

On the patchset readme...
11.3 Upgrade of Oracle Enterprise Manager Not Supported
When you start Oracle Database Upgrade Assistant to upgrade 10.2.0.1 database to 10.2.0.3 patch set, the following error occurs:
Inplace upgrade of Enterprise Manager is not supported for RAC databases is not supported in this release
Workaround:
Ignore warning.
If you drop and recreate the EM repository?
1). emca -deconfig dbcontrol db repos drop
2). emca -config dbcontrol db -repos create
Be careful, doing this put the database on QUIESCE mode.

Enterprise Manager 10g Java Console for Windows

Dear all,
I have download Complete Files of Oracle10.1.0.2 for Microsoft Windows (32-bit). After installation, When I opened Web-based Oracle Enterprise Manager 10g; I see the following tip on the Administration page
TIP Use the Enterprise Manager 10g Java Console to manage Streams, Advanced Replication, Advanced Queues, XML Database, Spatial and Workspace.
But I am still looking from where it can be launched. Have any professional experienced the Enterprise Manager 10g Java Console on MS Windows platform?
Regds,
Faran

It is not installed by default, you have to mark its
checkbox explicitly. In the package selection tree, it is
under Oracle Client 10.1.0.2.0.
It's only a Beta! But it's much more stable and a little
bit faster than 9iR2. They probably didn't check it for
default installation as it's just a beta.
There's one another interesting issue with Enterprise
Managers (Java and web) in 10g: each of them recommends
you in the welcome page to use the other one. What was
first, the chicken, or the egg???

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
<b>I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?</b>
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
