Performance Tuning for Content Manager

multiple item types or within a single item types. The Library tab in the Search

Configuration dialog enables the user to identify whether the search will be

performed across all item types in the library or against a specific item type.

As with the standard search, searching across multiple item types requires the

search to be performed against multiple tables in the database. In contrast, when

the search is performed within a single item type, the database search is run

against a single table, resulting in increased responsiveness to the end user.

Using the case-insensitive search setting within the power search also results in

increased search results responsiveness. Performing case-insensitive searches

requires the database query to complete a full table scan instead of using the

database indexes. Use of database indexes improves response performance for

the search being performed.

Service manager

Document Manager services can be set to minimize resource utilization on the

Document Manager server.

Each Document Manager service has a login frequency setting. This setting

determines how often the service wakes up and checks for work. The installation

default for this setting is to check every 30 seconds.

The interval at which each service is set to process should be evaluated as part

of the overall optimization of the Document Manager server. If a service such as

Lifecycle or Rendition is not being utilized often or if there is no need to see

immediate action, then the frequency interval can be set higher.

Blackout periods should be set for times when system backups are performed.

Managing the services through the processing intervals and setting blackout

times contributes to system stability and responsiveness.

Setting processing intervals to longer durations frees up resources on the

Document Manager server for other operations and system needs. Configuring

blackouts to be in effect during database outage times (such as when the

database is being backed up) eliminate the effort and processing put forth on the

part of the server during those times to connect to a system that is unavailable.

Blackouts also contribute to system stability because the Document Manager

server will not encounter errors in trying to connect to an unavailable database.

All Document Manager services should be managed (stopped and started) by

Document Manager Service Manager. The service manager is designed to allow

the Document Manager services to complete any in-process work when a

service is stopped.
