Planning for the HDS
Follow these guidelines to ensure that your Historical Data Server (page 16) is congured to
meet reporting needs:
Decide how many Historical Data Servers you require.
The number of Historical Data Servers that you congure depends on how long the HDS
will take to back up and on your reporting demands. If you are storing large amounts of data,
backup might take several hours. Do not run historical reports on an HDS while it is backing
up, as this might decrease performance. If you want to run reports while the HDS is backing
up, congure at least one additional HDS to use to run WebView reports.
See the Cisco ICM/IPCC Enterprise & Hosted Editions Release 7.1(1) Hardware and System
Software Specications (Bill of Materials) for guidelines on Reporting Users per HDS and
HDS capacity.
Determine the size of the HDS.
The size of the database depends on the size of your conguration and on how long you want
to retain data.
Conguration that impacts the size of the HDS includes the number of Call Types, skill
groups, agents, skills per agent, routing clients, trunk groups, services, peripherals, scripts,
calls routed daily, and calls terminated daily.
The larger the conguration, the bigger the HDS must be to store data. For example, the
historical Call Type database tables store data for each Call Type for each ve minute and
half-hour interval.
The amount of time that you want to retain data on the HDS also affects database size. Decide
how long you want to retain reporting data before it is automatically purged from the databases.
Data beyond the congured retention time is purged each day at 12:30 PM.
You can use the Database Administration (ICMDBA) tool to estimate the sizes of your
databases. The tool prompts you for your conguration information and the amount of time
that data is retained in the databases.
Determine how you want to back up the HDS.
You can back up the HDS either while the HDS is running or while it is ofine (generally
when the contact center is closed or during a time with low call volume).
Performing a backup during peak hours while the HDS is running can impact performance,
especially if you are backing up a large amount of data. While the HDS database is being
backed up, new data from the Logger is stored in the transaction log. If the transaction log
