To access other Data Modeler features (such as specifying design rules and user preferences), click Tools, then Data Modeler. If you have made an error in your JDK specification or configuration, you can try editing the SetJavaHome line in product.conf. Displays the available web browsers and the default browser for Check for Update operations. You can add, edit, and remove comment templates, and you can export templates to an XML file or import templates that had previously been exported. Versioning preferences affect the behavior of the version control and management systems that you have available for use with SQL Developer. If an option is specified as true for a connection in this pane, you will not be prompted with a message about the option being required when you use that connection for a feature that requires the option.

For example, the area that is probably improved most frequently is the SQL Optimizer, on which any application you develop is going to depend. The reason is simple – your critical business systems are in the hands of your Production DBAs and you have to be able to trust them to be competent and reliable. If something goes wrong in a development environment, time might be lost, but customers shouldn’t be affected directly. However, implicit in that view is that Development and Test databases aren’t very important, and Production-orientated DBAs often exhibit very casual attitudes towards caring for non-Production environments.

Establishing secure credential management in .NET

When you unplug a pluggable database (PDB), Oracle stores metadata for the PDB in an XML file. You can use this XML file to subsequently plug the PDB into a container database (CDB). I can’t help thinking that unless you have a good DBA on a development team and use him or her as a consultant on all database matters, we’re all losing out. I end up having work thrown at me that I could teach a trainee to do, which is a waste of my talents, and the development team’s database skills might be ‘good enough’ but could be so much better. If you come to my desk and say, “Here, we need you to run this script to create a bunch of new objects for a new messaging system we’re developing”, what would be the likely outcome? However, if you come to my desk and say, “We need to create a new messaging system, what’s your advice on the possible approaches?

• To create a separate unshared worksheet for a connection, press Ctrl+Shift+N.
• To view any Data Modeler report, expand the Data Modeler Reports hierarchy and double-click the desired report.
• By default, Oracle Database automatically generates snapshots of the performance data once every hour and retains the statistics in AWR for 8 days.
• Set up short master-classes covering new features or even just the important basics.
• You can use directory names when referring to BFILEs in your PL/SQL code and OCI calls, rather than hard coding the operating system path name, for management flexibility.

If they consult a DBA at all, it will generally be for a fairly routine task such as moving data around or creating user accounts. While such tasks are important, it reduces the role of development DBA to little more than a highly paid operator, with sufficient privileges to do the bidding of developers. This is a real pity, in my view, as a good development DBA can offer so much more to the team than this. Many organizations don’t even have separate Production and Development DBAs and I think this is a mistake – a strong, development-focused DBA can prove extremely valuable to any database-centric development project. In this article I’ll explain why, starting with a description of the basic role of a Development DBA and then taking a look at how I think a Project Team can extend that role to get the best results from a DBA, and vice versa. As a DBA, and having worked alongside many DBAs with different attributes and personalities, I have some sympathy with that perspective.

Connect a .NET app to an external PostgreSQL database

The database belongs to the developers and I’m just taking care of it for them. We are not database guardians, who must be obeyed, but should be there to help and advise. RDBMS software has become richer in features and more complicated in recent years. In other words, the operational DBA aspects don’t change much, but the way you develop database-centric applications does.

Identify Oracle directories for default, log, bad, and discard directories to be used as defaults for the data load. If any of the optional directories are not specified here or in the wizard, the default directory is used. Note these are Oracle directory objects that must be created before the external table can be used, and the appropriate permissions must be granted.

Introduction to SQL

The XML Schemas pane lets you view all the currently registered XML schemas, add new schemas to support additional namespaces and elements, remove existing schemas, and unload schemas from memory. The CVS pane specifies options for use with CVS (Concurrent Versions System). To have files with a specific extension be opened by default by SQL Developer, click the file extension in the list, then check Open with SQL Developer in the Details area.
