Oracle WebLogic server is an enterprise-class J2EE application server. Oracle WebLogic server is part of the Oracle WebLogic platform and supports Oracle, IBM DB2, Microsoft SQL Server, MySQL, and other JDBC-compliant databases.
BMC Atrium Discovery uses the BEA.WebLogicApplicationServer pattern to discover a WebLogic application server instance and its version, to identify the JMX port, and most importantly for extended discovery, to determine whether JMX access is enabled.
Extended WebLogic discovery attempts to discover detailed information related to the WebLogic application server such as the J2EE domain, the J2EE applications running on the WebLogic application server, and the JDBC resources that the WebLogic application server is using. To do this, an additional pattern, WebLogic.ExtendedDiscovery, initially determines whether JMX access is enabled, and the JMX port has been identified. It then attempts to determine whether the WebLogic application server version is supported (see Supported product versions). If the WebLogic server version cannot be determined using a JMX query, then pattern execution ends.
If the JMX port has not been identified, the extended WebLogic discovery uses port 7001 by default. The WebLogic.ExtendedDiscovery pattern then queries the WebLogic Administration Server's JMX monitoring agent for details about the J2EE applications, application servers, databases, database servers, mail servers, web servers, J2EE domain, and J2EE clusters. Information returned is stored in the J2EEApplication Component, J2EEDomain Collection, JDBCResource Detail, or JavaMailResource Detail nodes.
Creation of a JDBCResource Detail node triggers the CreateJDBCToDatabaseSI pattern that searches the BMC Atrium Discovery model for a software instance (SI) representing that database. If the database SI is found, the pattern creates relationships between the WebLogic Application Server SI and the nodes representing the database (see Database nodes and relationships). If the host that the database runs on has not been scanned, no further work is undertaken. The WebLogic.ExtendedDiscovery.DiscoverWebLogic pattern is fully described in Configipedia.
Creation of a J2EEApplication Component node does not trigger any further operations.
If extended discovery fails, it falls back to using a host login and extracts information from the WebLogic configuration files to create and populate a WebLogic Application Server SI and its attributes.
For a full discovery of WebLogic you need the following credentials:
The relationships are created based on the way that the database type is represented. (For example, an Oracle database is represented as an SI whereas a MySQL database server is represented as an SI and the individual databases by Detail nodes with contained by relationships to the database server SI).
The following WebLogic versions are supported:
The following screen shows a successfully scanned WebLogic instance that is using an Oracle database server as its datasource. If a Microsoft SQL Server database is used, the Database Elements This Depends On row is displayed to indicate the actual database, because in this case the database server is represented by an SI. See Database nodes and relationships for more information.
The attributes section of the WebLogic SI contains sections for Components, Details, and Collections.
The extended WebLogic discovery is enabled by the activation of the WebLogic.ExtendedDiscovery pattern. This pattern is activated by default in a new installation of BMC Atrium Discovery, but in an upgraded appliance, it must be activated manually.
To use extended WebLogic discovery, you must configure the credentials for the WebLogic application server in the Credentials tab.
