CUBRID Manager Broker Management

A Broker is a multi-function connector, enabling the connection between a database and many different interfaces such as ODBC, OLEDB, JDBC, PHP, etc. For more information, see "Administrator's Guide."

A Broker consists of the names of individually configured Brokers and their SQL logs.

8.1. Broker Function

A Broker may contain several individual Brokers. For each Broker, you need to set a unique name, port, and shared memory ID.

You can check the status, edit the properties, or start/stop each Broker.

8.2. SQL Logs

All the executed queries are stored in the log file when the SQL_LOG parameter of the Broker is ON. This log file can be analyzed and re-executed with the CUBRID Manager.

View Log

This function reads the SQL log stored in the selected SQL log file and displays 100 lines at a time. It also provides a function for selecting and copying a specific area of the log information.

Analyze Log

When Analyze Sql Log is selected, the Select File(s) to Analyze dialog box appears. You can select which Broker's SQL log is to be analyzed. When the Transaction based analyze check box is selected, the log is analyzed for each transaction; otherwise, they are analyzed for each query.

If you select the SQL log file you want and then OK in the Select File(s) to Analyze dialog box, the Sql Log Analyze Result dialog box which shows the results appears.

  • Log File : Displays the file name and the directory path of the SQL log file of the target Broker.
  • Analyze Result : Shows log analysis results. If Transaction based analyze is selected, each transaction's execution time is displayed; otherwise, analysis information (e.g. total number of executions, number of errors, maximum execution time, minimum execution time, average execution time) about each query is displayed. When you click a column in the analyze result section, the results are sorted by the value of that column.
  • Log Script : Shows the log script for the analysis results.
  • Execute Result : Shows the results of the log execution.
  • Execute log : Re-executes the SQL log in the log script. You can tune queries and correct errors by modifying and re-executing log queries.
  • Save log script : Saves the log script in a file.

Execute Log

If you select Execute log, the Set Execution Information dialog box appears, in which you can configure the environment.

  • Database name : Select the database for which the log is to be re-executed.
  • Broker name : Select the Broker for which the log is to be re-executed.
  • User ID/Password : Enter the ID and password of the database user that re-executes the log.
  • Concurrent thread num : Specify the number of times to execute the log query concurrently. When the log is re-executed, threads are created as many as this number, and the same query is executed concurrently. This function is useful when you want to check how a query is executed in a multi-user environment.
  • Repeat count : Specify the number of times to execute a query repeatedly.
  • Show query result : Shows the results of the query execution.
  • Show query plan : This option is valid only when Show query result is selected.

Log Property

Provides information of the selected log file.
