Work with data replication service properties files

We can use properties files to create, modify, or delete data replication service (DRS) properties and custom properties.

Determine the changes to make to your DRS configuration or its configuration objects.

Start the wsadmin scripting tool. To start wsadmin using the Jython language, run the wsadmin -lang jython command from the bin directory of the server profile. Using a properties file, we can create, modify, or delete a DRS instance. We can also create, modify, or delete servlet cache custom properties.

Run administrative commands using wsadmin to create or change a properties file for a DRS instance, validate the properties, and apply them to your configuration.

Actions for DRS properties files. We can create, modify, and delete DRS properties.

Action	Procedure
create	Set required properties and then run the applyConfigProperties command.
modify	Run the applyConfigProperties command to modify the value of a custom property.
delete	Run the deleteConfigProperties command to delete a property. If the deleted property has a default value, the property is set to the default value. To delete the entire DRSSettings object, uncomment #DELETE=true and then run the deleteConfigProperties command.
create Property	Not applicable
delete Property	Not applicable

Actions for DRS custom properties. We can create, modify, and delete DRS custom properties.

Action	Procedure
create	Not applicable
modify	Run the applyConfigProperties command to modify the value of an existing custom property.
delete	Not applicable
create Property	Run the applyConfigProperties command to create a custom property.
delete Property	Run the deleteConfigProperties command to delete an existing custom property. The properties file must contain only the properties to be deleted.

Optionally, we can use interactive mode with the commands:

AdminTask.command_name('-interactive')

• Create a properties file for a DRSSettings object.

  1. Set DRSSettings properties as needed.

     Open an editor on a DRSSettings properties file. Modify the Environment Variables section to match your system and set any property value that needs to be changed. To specify a custom property, edit the AttributeInfo value and properties values. An example DRSSettings properties file follows:

     #
     # Header
     #
     ResourceType=DRSSettings
     ImplementingResourceType=ServletCacheInstance
     ResourceId=Cell=!{cellName}:CacheProvider=myCacheProvider:ServletCacheInstance=jndiName#myServletCacheJndiName:DRSSettings=
     AttributeInfo=cacheReplication
     #DELETE=true
     #
     
     #
     #Properties
     #
     overrideHostConnectionPoints={}
     ids={} #integer*
     messageBrokerDomainName=null
     dataReplicationMode=BOTH #ENUM(SERVER|CLIENT|BOTH),default(BOTH)
     preferredLocalDRSBrokerName=null
     
     #
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=myCell04

  2. Run the applyConfigProperties command to create or change a DRS configuration.

     Running the applyConfigProperties command applies the properties file to the configuration. In this Jython example, the optional -reportFileName parameter produces a report named report.txt:

     AdminTask.applyConfigProperties(['-propertiesFileName myObjectType.props -reportFileName report.txt'])

• Modify an existing properties file.
  1. Obtain a properties file for the DRSSettings to change.

     We can extract a properties file for a DRSSettings object using the extractConfigProperties command.

  2. Open the properties file in an editor and change the properties as needed.

     Ensure the environment variables in the properties file match your system.

     To specify a custom property, edit the AttributeInfo value and properties values; for example:

     #
     # Header
     #
     ResourceType=DRSSettings
     ImplementingResourceType=ServletCacheInstance
     ResourceId=Cell=!{cellName}:CacheProvider=myCacheProvider:ServletCacheInstance=jndiName#myServletCacheJndiName:DRSSettings=
     AttributeInfo=properties(name,value)
     #
     #Properties
     #
     existingProp=newValue
     newProp=value
     
     #
     EnvironmentVariablesSection
     #
     #
     #Environment Variables
     cellName=myNode04Cell

  3. Run the applyConfigProperties command.

• If you no longer need the servlet cache or an existing custom property, we can delete the entire servlet cache object or the custom property.
  • To delete the entire object, specify DELETE=true in the header section of the properties file and run the deleteConfigProperties command; for example:
    AdminTask.deleteConfigProperties('[-propertiesFileName myObjectType.props -reportFileName report.txt]')
  • To delete a custom property, specify only the property to be deleted in the properties file and then run the deleteConfigProperties command.

Results

We can use the properties file to manage the DRS object and its properties.

Save the changes to your configuration.
