MAXTASK, MAXLOC and TRANSFERS_ALLOWED Parameters

CA XCOM Data Transport uses the MAXTASK, MAXLOC, and TRANSFERS_ALLOWED configuration parameters as well as the number of concurrent transfers running on each Worker Server to determine ranking. One server can receive all transfers that are based on this ranking system. For example, if transfers complete quickly, the same Worker Server can always be available. Alternatively, if a server has many long running transfers or a low MAXLOC value, this Worker Server receives a high ranking. If a Worker Server reaches the MAXLOC, the maximum number of locally initiated transfers, this Worker Server also receives a high ranking. If locally initiated transfers are disabled using the TRANSFERS_ALLOWED value, the server receives the highest ranking to prevent rejection of transfers that are submitted to the PLEXQ. Transfers scheduled for a future time are not considered when determining rank.

Notes: The MAXTASK and MAXLOC parameters provide the following default options:

• MAXTASK—The CONFIG parameter that specifies the maximum number of file transfers that the CA XCOM Data Transport server can perform concurrently.
• MAXLOC—The CONFIG parameter that specifies the maximum number of locally initiated transfers that can be active at one time.
• The TRANSFERS_ALLOWED parameter provides the ability to restrict a server from processing locally and/or remotely initiated transfers.
