Then,as an alternative, I tried to cretae a database link as below:Дў connect to dewadba identified by dewadba98 SQL> CONNECT - connected to remote database ORA-02019: connection description for remote database not found SQL> CREATE TABLE T12 AS SELECT * FROM TABLE T12 AS SELECT * FROM at line 1: SQL> CONNECT DEWADBA/DEWADBA - Connected to local database My problem description is detailed below: For example I create database link ora8idevДatabase link select * from do not have to use the connect to and identified by clauses, if I do not, it will use the login and password of the currently connected user to connect to the remote database.

PL/SQL Release 8.1.5.0.0 - you have that setup, you log into the database (the local database - the one you want to create the database link in to connect to the OTHER database) and issue the create database link command (see the sql reference manual for complete syntax). Oracle8i Enterprise Edition Release 8.1.5.0.0 - Production Sqlplus the machine the server you want to create the database link ON works - you've gotten the first step done. Configure queries to run multiple times in parallel and see how they respond to your simulated production environment without the risk of actually testing in production.You need a tnsnames entry in your tnsnames.ora on the server. Load testing verifies performance of existing and alternative SQL queries against the database. Utilize reporting to allow sharing of information captured during the profiling process. Also, explain plans are provided for a better understanding of how SQL will be executed and the performance costs. Continuous profiling monitors an entire data source within a configurable span of time. Identify Performance Bottlenecks ImmediatelyДatabase profiling provides a graphical visualization of wait-time analВysis, making the SQL that is causing poor database performance easy to pinpoint. The VST diagram displays indexes and constraints on tables and views with table statistics, as well as the joins used in a SQL statement such as Cartesian joins, implied Cartesian joins and many-to-many relationships. This approach helps DBAs and developers understand the impact of SQL statements on the database.

Unique in the industry, Visual SQL Tuning (VST) diagrams turn text-based SQL code into graphical SQL diagrams. Case Generation is used to generate all possible cases and to find the best alternative to a given SQL statement by including SQL rewrites and hint injections.

Color-coded Index Analysis shows used, not used, or missing indexes and offers recommendaВtions for optimum performance. The SQL tuning wizard automatically suggests solutions and provides essential context in tuning SQL code. Reduce training requirements and streamline collaboration among teams across the organization. Tune poorly performing SQL code on all major DBMSs (SQL Server, Oracle Database, Sybase ASE, and Db2 LUW, and PostgreSQL) from a single common interface. Load test alternative SQL queries in simulated production environment.Pinpoint problem SQL with database profiling of wait-time analysis.Tackle SQL queries with visual SQL tuning diagrams.
