When the POA is created with the NON RETAIN value -for servant retention, the Servant_Locator interface takes over. - -In this example, the Servant Activator as well as the Servant_Loactor -interfaces are used. The servant is an dynamically linkable library -which is loaded on demand. The case of the Servantor Activator once the -servant is loaded, the Object to Servant association is added to the -Active Object Map maintained by the POA. This association becomes -invalid when the POA is destroyed or/and the Object is deactivated. -On the other hand, the Servant_Locator is called per operation request -from the client and the associations too are made per request and the -servant is destroyed per request too. - -Also, the level of granualarity is at the object level. That is, every object -is associated with an dll which had to be loaded into memory on demand. - -Note that the server need not be built with the dll. The dll -name and the factory method which will be used to obtain the servant -is known to the server only at runtime. This gives us the flexibility -of modifying and loading the servant without having to build the -server along with the dll. - - -Execution: ---------- - - Run the run_test_pl perl script. - -example: - run_test_pl -f ior_file - - -The output will demonstrate the different actions performed by the -Servant_Manager via the Servant_Activator and the Servant_Locator -interfaces. |
