Total Records—This column shows the projected number of metadata records for each metadata file,
given the assumptions from the assumption worksheet. The formulas for computing the number
of records are shown below. Note that the variable names on the left match the metadata file names
listed in the Subsystem/Metadata File column while variables on the right of the equals sign (“=”)
represent values from the assumptions worksheet (unless otherwise noted).
The following are subsystem independent:
ACCT/Accounting Policies (accounting) = 1
ACCT/Summary Records (acctsum) = Total Number of Users * (Avg Number of Levels Per
Hierarchy + 1)

Hierarchy + 1)
ACCT/Validation Records (acctvalidate) = Total Number of Users * (Avg Number of Levels Per
Hierarchy + 1)

GK/Server Configs (gkconfig) = Total Gatekeeper Servers
LOC/Location Server Policies (lspolicy) = 1
LOG/Log Client Server Configs (logclient) = Total Log Clients
