Internal Operation

The server receives requests for report data blocks stored on the Centera cluster.

The requested data blocks are handled as follows:

• If the data blocks are cached in memory, the server transfers those blocks using cross memory.
• If the data blocks are not already in memory, the server assigns the request to a thread that reads the requested blocks.
• If a thread is already allocated for this report, the request is processed. If not, an unused thread is allocated.
• If all threads are in use, the least recently-referenced thread is reassigned to this report. This is also the thread that has been allocated for at least a minimum amount of time (MINIDLE parameter).

  If a thread has been idle for a maximum amount of time (MAXIDLE parameter), it will be shut down and placed in unused status.
