When you copy or replace a folder or deploy a deployment group, the Repository Service first copies the folder or deployment group to temporary tables in the target repository database. During this stage of the deployment, you have read-only access to the target repository if you are copying but not replacing a folder, or if you are copying a deployment group. Workflows, sessions, and tasks that are running in the target repository continue to run. You can view them running in the Workflow Monitor after the deployment operation begins.

After the Repository Service copies all objects in the folder or deployment group to temporary tables, it moves the data from the temporary tables to the target repository. During this stage of the deployment, you no longer have read-only access to the target repository, and all running workflows, sessions, and tasks are blocked. When an Integration Service tries to access the repository to run a workflow, session, or task while a repository is blocked, the Repository Service denies access and returns the following message:

The error message appears in the Administrator tool, workflow log, or session log, depending on which operation the Integration Service tried to perform. For example, if the Integration Service tried to fetch session information to run a session in a workflow, the message appears in the workflow log.

The Integration Service pauses until the repository completes the deployment. It cannot fetch objects in that repository during this time.

When the repository allows access again, it displays the following message:

The Integration Service fetches the repository object and completes the workflow, session, or task.
