12 Configuring Log Loader

This chapter describes Log Loader configuration in the OPMN opmn.xml file.

It features the following topics:

Section 12.1, "Log Loader Process Module Configuration"
Section 12.2, "Log Loader Minimum Configuration"
Section 12.3, "Log Loader Complete Configuration"
Section 12.4, "Log Loader Attribute Descriptions"

12.1 Log Loader Process Module Configuration

The following lines load and identify the Log Loader process module. Management of Log Loader processes by the process module are identified by the module id.

<module path="$ORACLE_HOME/opmn/lib/liblogloader.so">
   <module-id id="LOGLDR"/>
</module>

12.2 Log Loader Minimum Configuration

The following lines represent the minimum configuration for Log Loader. Default values are assigned to all other configuration elements and attributes for Log Loader.

<ias-component id="LogLoader" status="enabled" id-matching="true">
   <process-type id="logloaderd" module-id="LOGLDR" working-dir="$ORACLE_HOME">

12.4 Log Loader Attribute Descriptions

This section describes the attributes that are specific for Log Loader. This section also provides attribute descriptions of the attributes.

The Log Loader attributes are described with the following format:

Title: This is the attribute name and value being defined. For example, id="LogLoader".
Required: This field defines whether or not the attribute is required in the component definition.
Default: This defines the default value assigned to the attribute. The default value appears in the installed version of the opmn.xml file or is assigned internally if the attribute is not present.
Valid values: If applicable, this field defines the valid values for the attribute. For example, LogLoader.
Path: This field defines in which elements the attribute can appear. For example, ias-component.

Path: ias-component

This id is required and cannot be changed.

id="logloaderd"

Required: true
Default: none
Valid values: logloaderd

Path: ias-component/process-type/process-set/module-data/
category/data

The parameters -Doracle.home and -Djava.security.policy are required and must be defined in this section.

id="class-name"

Required: false
Default: oracle.core.ojdl.loader.LogLoaderDaemon
Valid values: a Java class name
Path: ias-component/process-type/process-set/module-data/
category/data

id="application-parameters"

Required: false
Default: To start: -start -config $ORACLE_HOME/diagnostics/config/logloader.xml.
To stop: -stop -config $ORACLE_HOME/diagnostics/config/logloader.xml
Valid values: any valid Java application parameters that are recognized by the class specified in "class-name".
Path: ias-component/process-type/process-set/module-data/
category/data

This field enables you to set application parameters. Any parameters defined here will replace the default values.

id="stop-parameters"

Required: false
Default: none
Path: ias-component/process-type/process-set/module-data/
category

This indicates the configuration block for stop-parameters category. In this category, some stop related module data can be specified.
