Performance Tuning for Content Manager

Appendix A. Performance tuning guidelines for a Document Manager system 439

Class configuration

The document class definition allows the ability to identify an attribute or

combination of attributes that the system uses to check document uniqueness.

Uniqueness can be checked at several different points in the life cycle: a

document add, a document check-in, and the document revise commands can

all check for uniqueness.

When uniqueness is checked, the system reads the information set in the

Properties tab of the class configuration. Using three or more attributes as

uniqueness criteria can increase the amount of time it takes to check

uniqueness. For best performance, use the fewest attributes possible to meet

your business and configuration needs; not checking for uniqueness at all will

provide the best performance possible.

If you do have the system check for uniqueness, it is important to consider

creating attribute indexes for all properties used within the properties tab.

You can achieve additional server performance improvements through the

settings in the Triggers tab of the document class configuration dialog. These

triggers are all processed by the Document Manager Lifecycle Manager

whenever a document action is performed. Although this setting does not affect

desktop performance, reducing the number of triggers that have to be processed

by Lifecycle Manager helps to alleviate unnecessary resource use on the server.

Power searches

The power search command is an advanced level utility that can be made

available to users to build complex search requests. The power search was not

created to provide highly optimized searches, but it gives users the ability to

choose any combination of attributes, operators, and library settings when they

run a search.

We recommend making the Power Search command available to power users or

more advanced users with the knowledge of how to build a complex search.

Used correctly, refined complex searches can be created to return specific

documents and data to the user quickly.

User training and education can help provide knowledge and skills around

building complex searches. Using operators such as equals and choosing

attributes that are indexed help to improve search results response time.

Gain additional performance through the library settings in the Power Search

dialog. Similar to the standard search, a Power Search can be performed across
