    The LIFECYCLE_PARAMETERS file must be in <install_path>\veritas\netbackup\db\config folder on the master server. (Please also ensure that Windows explorer did not add a .txt extention.)

    Explanation of TAPE_RESOURCE_MULTIPLIER setting in LIFECYCLE_PARAMETERS:

    Another parameter that is only used in NetBackup 6.5.5 and above, this value determines the number of duplication jobs that the Resource Broker will evaluate for granting access to a single destination storage unit.
    Storage unit configuration includes limiting the number of jobs that can access the resource at one time. The Maximum concurrent write drives value in the storage unit definition specifies the maximum number of jobs that the Resource Broker can assign for writing to that resource.
    Overloading the Resource Broker with jobs that it can‘t run is not prudent. However, we want to make sure that there‘s enough work queued so that the devices won‘t become idle. The TAPE_RESOURCE_MULTIPLIER parameter lets administrators tune the amount of work that is being evaluated by the Resource Broker for a particular destination storage unit.
    For example, a particular storage unit contains 3 write drives. If the TAPE_RESOURCE_MULTIPLIER parameter is set to 2, then the Resource Broker will consider 6 duplication jobs for write access to the destination storage unit.
    The default is 2. This value is appropriate for most situations. This is not configurable for versions of NetBackup prior to 6.5.5; a value of 1 is used.
