• Always display Column names in results.
• Change Read Only / Read- Write Mode.
• Change Object Folder Display.

• Txn Isolation Level: Support for setting Transaction Isolation Level
  - TRANSACTION_NONE - A constant indicating that transactions are not supported.
  - TRANSACTION_READ_COMMITTED - A constant indicating that dirty reads are prevented; non-repeatable reads and phantom reads can occur.
  - TRANSACTION_READ_UNCOMMITTED - A constant indicating that dirty reads, non-repeatable reads and phantom reads can occur.
  - TRANSACTION_REPEATABLE_READ - A constant indicating that dirty reads and non-repeatable reads are prevented; phantom reads can occur.
  - TRANSACTION_SERIALIZABLE - A constant indicating that dirty reads, non-repeatable reads and phantom reads are prevented.
• Always display column name in results: enables/disables displaying column names in results.
• Enable db filters for query window: enables/disables db filters for query windows using this connection.

• Data Warehouse Mode: Read Only or Read/Write
• Object Folder Display: [Default], [Name], [Schema].[Name] or [Name]([Schema]) sets how the Schemas will be displayed.
• Object Folder Schema Folder Grouping: Default, Yes or No. Schema Folder Grouping makes finding tables much easier because it groups them instead of showing each object individually.

Tip : Using the dropdown at the bottom of the Advanced Tab, quickly change your Object Display in the Server Browser.

Using Driver Properties (Driver Tab)

Edit the Drivers Properties to use Driver Parameters in Aqua Data Studio:

• Locate the Server in the Server Browser.
• Right Click on the Server - A Popup Menu Appears.
• Click on the Item which displays Server Properties.
• Go to the Driver Tab and make changes in the Options.

  With options in Driver properties of a Server, you can edit/view the :

• Driver Parameters: This option is to allow a user to specify extra JDBC parameters that a user might want use in estabilishing a connection.
• Connection URL: This displays the connection URL for this server connection.
• Driver Parameters Quickfilter: This option is to allow a user to search JDBC parameters that a user might want to use in estabilishing a connection.

Tip: To use SSL in Aqua Data Studio, you must add the option"?ssl=true" in the "Driver Parameters:" in the Driver Tab of a Server Registration.

    openssl req -new -text -out server.req           

Fill out the information that openssl asks for. The challengepassword can be left blank. The program will generate a key that ispassphrase protected; it will not accept a passphrase that is lessthan four characters long. To remove the passphrase (as you must ifyou want automatic start-up of the server), run the commands

    openssl rsa -in privkey.pem -out server.key    rm privkey.pem

Enter the old passphrase to unlock the existing key. Now do

    openssl req -x509 -in server.req -text -key server.key -out server.crt    chmod og-rwx server.key

to turn the certificate into a self-signed certificate and copythe key and certificate to the data directory of the server. Nowconvert the server.crt to a format java can import on theclient:

    openssl x509 -in server.crt -out server.crt.der -outform der

Now import the cert into the java keystore:

keytool -keystore [your java home here]/lib/security/cacerts -alias  [any name for cert desired] -import -file server.crt.der

enter the password for the cacerts keystore (default is’changeit’). Say yes to trust this cert.

Make sure your Aqua Data Studio instance knows which keystore touse for the SSL connection by adding to the startup script theparameter-Djavax.net.ssl.trustStore=\lib\security\cacerts

Windows: (Executable) - Modify the[ADS_INSTALL]\datastudio.ini
 - Add to the file vmarg.2=-Djavax.net.ssl.trustStore=\lib\security\cacerts"

Windows: (Batch) - Modify the [ADS_INSTALL]\datastudio.bator datastudio-bundled.bat
 - Last line should execute java with the parameter between"java" and "-cp" such as ...
"java -Djavax.net.ssl.trustStore=\lib\security\cacerts-cp"

OSX: - Modify /Aqua Data Studio/Contents/Info.plist

> ...
>    VMOptions
>
> -Djavax.net.ssl.trustStore=/Library/Java/Home/lib/security/cacerts
> -Xmx256m
>     MainClass
>     com.aquafold.datastudio.DataStudio
> ...
