One of our servers crashed and we had lost the complete file system and the Informatica folder. However,the repository database was on another server and it was intact. It was a challenge for the Informatica Administration Team to restore & recover several components including:-
We leveraged the “Content Already Exists in the Specified Database” feature available in the Informatica Administrator Tool during the re-installation process to re-install the server (Domain) & to re-establish connection with the existing repository.
Using the steps mentioned below, we could restore all the data successfully except the previously created users (we re-created the users)
Scenario: Recovery from the loss of the Informatica Server File-System folders
This ensures that the server is successfully installed. We should also check system services to confirm that the Informatica 9.5.1 service is running.
Because of unavailability of the Domain Metadata, we had to recreate the users / groups & roles.
DVO version- 9.5.2 was using the Powercenter Repository just restored, for this version, we need to paste DVOCT.jar file in the server location & set the Java SDKClassPath from Integration service processes tab (see snapshot below).
After restoration, check whether all services are “UP & Running”. Also check repositories from Powercenter / Data Quality Client Tools toconfirm that the mappings are running successfully by executing / testing sample mappings.
This completes the restoration of Informatica 9.5.1 server & repositories without losing any information or with manageable changes to the server.
Using the above steps, we were able torecover the entire serverin 2 hours.
Every outcome starts with a conversation
