In Strategy Desktop 9.x under the Administration > System Administration > Project, if an administrator right-clicks on a loaded project, there is an option to Idle/Resume a project that has been loaded in Strategy Intelligence Server 9.x.
Depending on the option selected, Strategy Intelligence Server 9.x will do one of the following:
Request Idle
This option completes execution of all currently executing and queued jobs but rejects newly submitted jobs. This option is shown below:

Execution Idle
This option cancels all currently executing jobs and places new jobs submitted after the project is in the Execution idle mode in the waiting job queue. These queued jobs are executed later after Strategy Intelligence Server 9.x resumes normal execution.
Strategy Intelligence Server 9.x continues to accept requests from clients for the project but does not submit any SQL to the database. The Execution Idle option is shown below:

a) All jobs: All jobs are restricted from being executed by Intelligence Server. In most cases, these jobs are placed in the job queue and resubmitted when the project is allowed to resume job execution.
b) Warehouse jobs: Only jobs that require SQL to be submitted to the data warehouse are restricted from being executed by Intelligence Server. In most cases, these jobs are placed in the job queue and resumed when the project is allowed to resume job execution.
Jobs that do not require SQL to be submitted to the data warehouse are executed as normal. For example, users can execute reports against an Intelligent Cube, run reports from a valid report cache, export to Excel, and so on.
Full Idle
This option cancels execution of all executing jobs and queued jobs and rejects any newly submitted jobs. This option is shown below:

For scheduled subscription jobs, if the project is put in Request Idle mode, they will be rejected and won't be resumed after the project is resumed.
If the project is set to Execution Idle mode, the subscription jobs will be put into job queue under some circumstances. On the all jobs level, all jobs are halted; while on the warehouse jobs level, subscriptions of reports and documents that is based on Intelligent Cube or valid cache can be executed.
