Administrators Developers Who Uses Oracle CEP Visualizer?

Overview of Oracle CEP Visualizer 1-11

1.4.2 Developers

Developers can use Oracle CEP Visualizer to view server resources such as data sources, perform event record and playback, and trouble shoot performance issues by turning on latency and throughput statistics.

1.4.3 Business Users

Business users can use the Oracle CEP Visualizer Query Wizard to create and modify queries within a given processor. This allows rule experts to manage Oracle CQL queries and views with minimal development assistance.

1.5 National Language Support

Oracle CEP Visualizer observes Java localization and supports the use of double-byte characters in all configuration files and Oracle CEP Visualizer text entry fields. This section describes topics of interest when using Oracle CEP Visualizer with double-byte locales, including: ■ Section 1.5.1, Configuration File Encoding: UTF-8

1.5.1 Configuration File Encoding: UTF-8

Oracle CEP server encodes all configuration XML files using UTF-8 encoding. This encoding is specified in the header of all Oracle CEP configuration XML files. Example 1–1 shows the encoding specified in the config.xml file. Example 1–1 UTF-8 Encoding Attribute in Oracle CEP Server config.xml ?xml version=1.0 encoding=UTF-8? n1:config xsi:schemaLocation=http:www.bea.comnswlevsconfigserver wlevs_ server_config.xsd xmlns:n1=http:www.bea.comnswlevsconfigserver xmlns:xsi=http:www.w3.org2001XMLSchema-instance domain Note: The security features of Oracle CEP Visualizer work only if you have security enabled for Oracle CEP server. If you disable Oracle CEP server security, then: ■ Oracle CEP Visualizer does not provide default users, groups, and roles. ■ You cannot create new users, groups, and roles. ■ There is still a login page when first entering Oracle CEP Visualizer but you may enter anything for user and password. ■ Anonymous users may access the Oracle CEP Visualizer. For more information, see Enabling and Disabling Security in the Oracle Complex Event Processing Administrators Guide Note: By default, Oracle CEP Visualizer ships with an English resource bundle that supplies all the text that appears in the Oracle CEP Visualizer user interface. 1-12 Oracle Complex Event Processing Visualizer Users Guide nameWLEventServerDomainname domain netio nameNetIOname port9002port netio ... config When manually editing an Oracle CEP configuration XML file, be sure to save the file in UTF-8 encoding. Some editors will automatically save configuration XML files in the correct encoding based on the encoding attribute. However, some editors will not automatically save configuration XML files in the correct encoding. In this case, you must ensure that you select UTF-8 encoding when you save an Oracle CEP configuration XML file. You can enter double-byte characters in any Oracle CEP Visualizer text field. The Oracle CEP Visualizer and Oracle CEP server will always write configuration XML files in the correct UTF-8 encoding.
