If you are running services and P6 on the same server, you should keep the defaults. If you want to send To Fusion immediately, you should set the Interval low (e.g., 10s) and the Concurrent Threads high (e.g., 20). Remember that if the server is actively sending to Fusion, all users will experience delays in the application.
To set your send to Fusion settings:
Open the P6 Administrator application.
In the Configurations tab, expand your configuration.
Expand Services/Send to Fusion.
In the Interval field, enter the amount of time the service will wait before scheduling the next available job (in 1d1h1m1s format - specifying only numbers without letters implies milliseconds).
The default is 10s. Oracle recommends you keep this setting as is.
Enter anything from 1s-24d20h31m23s647.
In the Concurrent Threads field, enter the number of processes used for this service on this server. A value of 0 indicates that the service is not available on this server.
The default is 2. Oracle recommends you keep this setting as is.
Enter anything from 0-20.
In the Active Mode field, choose true if you want jobs processed continuously until all jobs finish. Choose false if you want each job processed according to the Interval.
