A domain goes into offline mode when you deregister the domain or when there is a loss of connectivity between the domain and Informatica Intelligent Cloud Services. Because the service can't connect to or monitor the CDI-PC domain, the domain transitions to offline mode.
When you deregister a domain, the domain moves to offline mode immediately. If there is a loss of connectivity between the domain and Informatica Intelligent Cloud Services, the service is resilient to the temporary loss of connectivity with the domain for a period of two hours. During the two-hour resilience timeout period, the domain tries to reestablish connectivity. During this period, you can perform all tasks in the domain as usual. If connectivity can't be restored even after two hours, the domain goes into offline mode.
In offline mode, you can't log in or run jobs in a domain. Jobs that are in progress when the domain transitions to offline mode might be impacted. The impact depends on the time required for the job to complete and the authentication requirements of the job.
Note the following changes in a domain in offline mode:
•You can't initiate a session in the Administrator tool or the CDI-PC Client. You receive an error message which indicates that the domain is not connected to Informatica Intelligent Cloud Services.
•If you are logged in to the Administrator tool when the domain goes offline, you can continue to create new services.
•If you are logged in to the CDI-PC Client when the domain goes offline, you can't perform any create, edit, or delete operations. You can perform a limited number of operations such as viewing objects that are open.
•You can't start jobs with write or fetch operations to the CDI-PC Repository Service.
•You can't edit objects in offline mode. Editing objects requires write operations on the object metadata.
•If the domain goes into offline mode after you perform a write operation on an open object, if you keep the client session active, you can save the changes and run the operation when the domain comes online. If you close the CDI-PC Client, changes that you didn't save before the domain went offline are lost.
•If you are logged in to the CDI-PC Client when the domain goes offline, you can view and navigate through objects in folders that are already open. You can't open new folders after the domain goes offline.
•If a workflow is scheduled to run on a repeat schedule, it gets repeatedly rescheduled by 5 minutes while the domain is offline. Because of this, a scheduled workflow can take up to 10 minutes to run as per schedule after the domain is back online.
•You can't start, schedule, or recover workflows in offline mode.
•If the domain goes into offline mode when a workflow is in progress, all sessions and tasks in the workflow continue to run.
•You can retrieve logs for previous session and workflow runs in offline mode, but you can't view results of Get Run Properties operations. To fetch the run properties, the CDI-PC Repository Service must be accessible. Because the repository isn't accessible, Get Run Properties returns an error that the domain is not connected to Informatica Intelligent Cloud Services.
•You can't run pmrep or pmcmd commands for operations that require a connection to the repository.
•When the domain goes offline, jobs in progress continue if authentication is complete. Because authentication requests are blocked, the job fails at the next request for authentication.
•If you disable the CDI-PC Repository Service process on a node in a multi-node domain, the service becomes available on another node. The CDI-PC Client and pmrep might reconnect successfully to the service within the service resilience timeout period. Even though they reconnect to the service, since the domain is in offline mode, you can't perform any tasks that require a connection to the repository.
