CHAPTER 7 RESOURCE MANAGEMENTSession Attribute Type DescriptionCLIENT_MACHINE Login This is the machine from which the user is connecting tothe database. It appears in the MACHINE column of thev$session view.MODULE_NAME Runtime This is the module name set by the applicationconnecting to the database. It is stored in the MODULEcolumn of the v$session view and is set by calling theDBMS_APPLICATION_INFO.SET_MODULE procedure. This isan optional setting, and some applications do not use it.MODULE_NAME_ACTION Runtime This is a concatenation of the module and action in theform module.action. The application sets theseattributes by calling the following procedures:• DBMS_APPLICATION_INFO.SET_MODULE• DBMS_APPLICATION_INFO.SET_ACTIONSERVICE_MODULE Runtime This attribute is the concatenation of the service nameused to connect to the database, and the MODULEattribute in the form service.module.SERVICE_MODULE_ACTION Runtime This attribute is the concatenation of the service name,module, and action in the form service.module.action.ORACLE_FUNCTION Runtime This is a special attribute that is maintained internallyby the database. It is set when running RMAN or DataPump. This attribute can be set to BACKUP, to perform abackup … as backupset, or COPY, to perform a backup …as copy. When Data Pump is used to load data into thedatabase, this attribute is set to DATALOAD. Theseattributes are automatically mapped to built-inconsumer groups such as BATCH_GROUP and ETL_GROUP. Tip: SERVICE_MODULE, ACTIVE_SESS_POOL_P1, and QUEUEING_P1 are not commonly used and may bedeprecated in future releases. : For attributes other than ORACLE_USER and SERVICE_NAME in Table 7-2, you canalso use wildcards such as _ and % for single and multiple characters, respectively.Conflicts can occur between mapping rules when a user account matches more than one rule.Oracle resolves these conflicts by allowing you to specify the relative priority of each attribute. This way,Oracle can automatically determine which rule (attribute) should take precedence when sessionattributes satisfy multiple mapping rules. The default priorities for the ORACLE_USER andCLIENT_APPLICATION attributes are 6 and 7, respectively. In the following example, I’ve promoted the180
