Exporting Environment-Dependent and Independent Elements to Different Files

Note

This section describes the parameters --property includeEnvSpecificElements and --property includeNonEnvSpecificElements=yes of the export script. They are deprecated and it may not be available in future releases of the Denodo Platform.

They cannot be used to export the new types of environment-dependent elements added in Denodo 5.5. For example, a custom wrapper that has an input parameter that is a route is an environment dependent element. However, it will not be included in the output of the script when you use --property includeEnvSpecificElements=yes.

Virtual DataPort can export to one file the elements that depend on the environment where the Server is running, and to another file, the environment-independent elements. Then, you can edit the parameters’ values of the first file to match the configuration of the target environment before importing it. Afterwards, you can import the second file without any modification.

The elements that are considered dependent on the environment (option --property includeEnvSpecificElements=yes of the scripts export and import are the following:

  • Server settings. This includes the settings of the following items (settings that can be changed in the wizards of the menu Administration > Server configuration of the Administration Tool):

    • Cache engine

    • Concurrent requests

    • Default I18n

    • HTTP Proxy

    • Memory usage

    • Server connectivity

    • Stored procedures

    • Threads pool

  • JVM settings of the Virtual DataPort server and the Denodo Web Container (not the JVM settings of Scheduler). These are the settings that can be changed in the Denodo Platform Control Center, in the dialog “Configuration > JVM Options”.

    When these settings are imported, the Server regenerates the following scripts so they use the imported values:

    <DENODO_HOME>/bin/vqlserver
<DENODO_HOME>/bin/vqlserver_startup.l4j.ini
<DENODO_HOME>/conf/vdp/server.conf
<DENODO_HOME>/resources/apache-tomcat/bin/catalina

  • Users, but not their privileges. Their privileges are considered independent of the environment.

  • Roles, but not their privileges. Their privileges are considered independent of the environment.

  • JMS listeners

  • Database creation and configuration

  • Folders

  • Data sources including Custom data sources (also called Custom wrappers)

  • I18n maps: only those that are referenced by other environment-dependent elements. I.e.: databases.

  • Jars: only those that are referenced by other environment-dependent elements and you are using the option to deal with Jars. That is, if you are exporting from the Administration Tool, the option Include Jars is selected. Or, if you are using the scripts export or import and you add the parameter --property includeJars=yes.

The elements that are considered independent of the environment (option --property includeNonEnvSpecificElements=yes of the scripts export and import are the following:

  • Privileges assigned to users. The creation of users is considered dependent on the environment, but not their privileges.

  • Privileges assigned to roles. The creation of roles is considered dependent on the environment, but not their privileges.

  • Folders

  • Wrappers, which are considered dependent on the environment.

  • Types

  • Views (base and derived views)

  • Denodo Stored procedures

  • Web services: includes the creation of the Web services and if necessary, the information to deploy them.

  • Jars: only those that are referenced by other environment-independent elements and you are using the option to deal with Jars. That is, if you are exporting from the Administration Tool, the option Include Jars is selected. Or, if you are using the scripts export or import and add the parameter --property includeJars=yes.

  • Simple maps

  • I18n maps: only those that are referenced by other environment-independent elements such as views, Web services, etc.
