Using concurrency control

Users can ease the severity of NIM installations becoming overburdened when they are being performed on a large number of clients at the same time by controlling the number of clients that are installed.

NIM installations can become overburdened when they are being performed on a large number of clients at the same time. This can be caused by network bandwidth or workload on the NIM servers.

The concurrent and time_limit attributes can be used in conjunction with the bos_inst, cust, and alt_disk_install operations to control the number of client machines being operated on simultaneously from a client group. The concurrent attribute controls the number of clients in a group that are processing a particular operation at one time. After a client finishes the operation, another client will initiate the operation one at a time. The time_limit attribute prohibits NIM from initiating an operation on any more clients of the group, after the specified time (in hours) has elapsed.
