Oracle SQL Developer to be used in laptop

Hi all,
I have downloaded oracle sql developer for my Windows 7 laptop. I am able to make SQL queries but unable to run any PL SQL block. I am unable to create any connection and gettinf an error 'IO Error: The Network Adaptor could not establish the connection.'
I do not have oracle installed in my local system. I just want to write a few blocks and use it for my personal purpose. But for packages, procedures etc it is not allowing me use any connection.
I want a simple application for my personal use only which will help me to learn the basics.
Please guide me regarding that.

Oracle SQL Developer issue when using VPN (Cisco)

All,
We've got a somewhat obscure issue with SQL Developer connectivity to our databases from a remote employee's laptop.
The database is hosted inside our firewall and when the employee tries to connect to the database he receives the following error:
+"Error Encountered: An error was encountered performing the requested operation: The network adaptor could not establish the connection. Vendor Code 20"+
I believe I may have seen the following error at one point as well...
Status : Failure -Test failed: IO Error: The Network Adapter could not establish the connection
Note: He gets this error when logged into our VPN & while he can connect via SQL*Plus to that same database. He gets the error regardless if he uses the tnsnames entry option in SQL Developer or if he is using the "Basic" connection type.
What's interesting is that if he disconnects from the VPN, turns off his wireless connectivity and then hard-wires into our network he can connect, no issue.
The strangest part for me is that while he can not connect to the database via SQL Developer, he can connect via SQL*Plus. He can ping the source IP address fine, he can tnsping the database no problem, he can connect via SQL*Plus, he just can't connect via SQL*Developer. Since SQL*Plus and tnsping are working, I know he can access the db server via port 1521, so I don't think it's a port issue.
Another strange thing: When he connects to our network via an "old" VPN (open VPN) he has no issues.
His machine is Windoz 64 bit (HP laptop) and he's using the latest version of SQL Developer and a newer JVM.
Also interesting: I also have a Windoz 64 bit laptop (Lenovo) and I do not have the same issues as he does. I however am running an older version of SQL Developer and probably an older JVM.
I dug around a bit, seems like perhaps this has something to do with IPv6? No idea what to do next except have my network guy look at firewall logs to try to capture where the connectivity is being dropped.
Any thoughts or suggestions would be appreciated. I've tried all kinds of things (giving him my tnsnames.ora and sqlnet.ora file, manually editing those files, tried IP addresses instead of host names, tried host names with the .doman.org extensions, etc.).
Again, any suggestions would be appreciated and thank you very much.

Since SQLPlus is installed and works fine you could try to set
Tools -> Preferences -> Database -> Advanced -> Use OCI/Thick driverThis should enable SQLDeveloper to use the same oracle client SQLPlus is using to connect to the database.
Mind that by setting this option you need to have an 11g client (or instant client) installed that matches the ojdbc6.jar version used by SQLDeveloper, so if you are using an older client this may not be a usable solution.

Oracle SQL Developer for personal use?

Hello,
I would like to use Oracle to test out my SQL commands, however I do not have a connection set up (at home). Is there a way I can create databases and tables without setting up a connection to a database. If that isn't possible, is there a tutorial avaliable somewhere to set up a connection on a local machine. Operating system is Mac OSX, however I do have Windows 7 64-bit available as well. Thanks in advance for your help/sugguestions.

Without making a connection to the db, there isn't any chances that you can issue the sql statements. So you must have to have a connection with either an existing db or make a new db and get connected to it. The another way , to run sql statements, is to just connect using plain black window (terminal) using o/s authentication . This won't need any tns settings at all but you won't get that good looking GUI interface of Sql Developer as well. That's my preferred way to work with db but you may have a different preference still you can give it a try if you want to.
The setup is pretty straightforward. You need to pass the information of your host with the appropriate user name and password and it would be done. Once you start doing it, keep the thread updated with your efforts so that we can guide you in case you would face troubles.

Unable to connect to Oracle Database using Oracle Sql developer 2.1.1.64

Hi Everyone,
I am searching for some help regarding my problem with Oracle connectivity. I have installed Oracle 11g release 2 on my Windows XP Professional Laptop. For a few days after installation i could connect to the Oracle database with the SYSTEM account using Oracle SQL developer ( installed on the same Laptop) but now i am unable to do so.It gives me this annoying message:

I am new to Oracle and so i need someone in this forum who can help me resolve this problem. Also i even tried connecting to the database using Toad 10.5.0.41. It give me the following error:
ORA 12537 : TNS Connection closed
Thanks for your patience and help in advance.

Table API Extension for Oracle SQL Developer

I just created small project [Table API Generator for Oracle|http://code.google.com/p/tapig/].
Idea is to only maintain tables and generate table API (TAPI) packages for data manipulation.
Generated:
- insert, update, delete, querying procedures
- documentation based on table columns comments
Do you think it will be useful to have custom Table API Generator as extension for Oracle SQL Developer?

Never used them myself and quite legacy, but I'm sure there's still a lot of people using them and the basic idea is quite nice.
This would also qualify perfectly as a User Defined XML Extension for sqldev; little work but big results. Even if you were the only one using it, it would still pay off.
Have fun,

How to use Oracle SQL Developer 4.0 to connect to Ms Access file with .accdb extension

Hi all,
I am using Oracle SQL Developer 4.0 and Ms Access 2013 under Windows 7 (64 bits)

Would you please advise?
Thank you very much in advance

That MS Access driver is 64-bit, I think. If SQL Developer, or JDK is 32-bit you need to use the 32-bit driver.   You can see if you have a 32-bit driver installed using c:\windows\system32\odbcadm32.exe

Hi,
One prior post discussing the use of Java 7 is:
SQL Developer 3.0 and Java SE 7?
There is no need to uninstall any Java version (except if you have disk space constraints) and no problem switching between Java versions. This may be controlled in the sqldeveloper.conf file in your ...\sqldeveloper\sqldeveloper\bin directory via the SetJavaHome line. For example:
#SetJavaHome ../../jdk
SetJavaHome C:/Program Files/Java/jdk1.6.0_26
#SetJavaHome C:/Program Files/Java/jdk1.7.0Regards,

Using DEBUG Mode in Oracle SQL Developer Data Modeler to Log SQL

Hello,
I am looking for the possibilty to enable the logging of SQL in Data Modeler.
Jeff Smith wrote an article how to do this for SQL Developer, for Data Modeler there are other configuration files. Does anyone have an idea?
Best regards,
Joop

Hello Philip,
the URL to the article of Jeff is: http://www.thatjeffsmith.com/archive/2012/10/using-debug-mode-in-oracle-sql-developer-to-log-sql/
in the install directory of Data Modeler 3.3.0.734 exists a file datamodeler\datamodeler\bin\datamodeler.conf. This analogue the situation for sql Developer.
However in this file there is no reference to a (non)debug file.
In ide/bin directory there is a ide-logging-debug.conf and ide-logging.conf file. But they are not referenced. Should one of them be included?

Optimizing an SQL Query using Oracle SQL Developer

Hi ,
Currently i am using Oracle SQL Developer as my Database IDE .
Is it possible to use Orqcles SQLDeveloper for the purpose of Optimizing an SQL Query ??
For example assume i am having a query as :
Select from Tranac_Master where CUST_STATAUS='Y' and JCC_REPORT='N'*
Could anybody please tell me how can i use Oracle SQL Developer to optimize this query or any other SQL queries ??
Please share your ideas , thanks in advance .

1. Your query looks very simplistic as it is, so I fail to see how you can better optimise it (unless 'Tranac_Master' is a view, in which case I'd need to see the view details).
2. No tool can automagically optimise your SQL to any degree of practical use. Very minor adjustments may be possible automatically, but really it is a question of you knowing your data & database design accurately, and then you applying your expert knowledge to tune it.
