Global Services (SAP Library - Knowledge Management)

Global Services

Use

Global services enable basic functions in CM, such as using predefined properties. They are also prerequisites for executing applications such as the XML Forms Builder.

Unlike the repository services, you do not need to activate global services for individual repositories. They are applicable to all repository types that are managed by the repository framework.

Integration

Global services are also used by other components such as Collaboration.

Features

The following table gives an overview of the global services in Content Management.

Overview of Global Services in the Standard Delivery

Global Service	Description	Preconfigured and Active
Audit Log Service	Used for logging changes to documents, folders, and links.	No. Configure and activate as required.
Crawler Service	Allows crawlers to collect resources that are located in internal or external repositories. The crawler service is also a prerequisite for other services. If you use Web repository managers, you need crawlers to allow these repositories to be indexed.	Yes. Configuration of your own crawlers and crawler profiles is possible.
Cache Service	Allows the use of caches	Yes
Content Exchange Service	You need this service if you want to automatically transfer content between repositories inside or outside your CM environment. It is based on the Information and Content Exchange (ICE) protocol standard.	Yes
Index Management Service	You need this service if you want to apply information retrieval and classification techniques such as indexing and classification to your documents and folders.	Yes
System Landscape Service	Delivers the information needed to log on to external repositories (for example, a WebDAV repository with authentication).	Activated. Manual configuration needed for cluster installations.
MIME Handler Service	Required for determining the MIME type of documents and for displaying the appropriate document icons in the folder view. It associates file name extensions and icons with MIME types.	Yes
Notificator Service	Required for creating and sending notifications about resource-related events, for example, when subscribed resources have been changed, or when a document has been rejected in an approval workflow.	Yes
Object Type Handler Service	Manages dependencies between resource types and actions to be performed.	Yes
Publishing Pipeline	Performs format and layout transformations of documents.	Yes
Service for Properties and Metadata	Required for defining properties and metadata for folders and documents.	Yes. Configuration of your own properties is possible.
Service for Property Structures	Allows you to group predefined properties in an ordered fashion and insert the groups into structures.	Activated. Configuration of your own property structures is possible.
Reporting Service	Used for the reporting functions	Yes
Service for Registration of Resource Types	Used for creating and managing resource types.	Yes. Configuration of your own resource types is possible.
Scheduler Service	Required for automatically performing recurring tasks at predefined intervals, such as checking for subscribed resources that have been changed.	Activated. Manual configuration of scheduler tasks needed for cluster installations.
Task Queue Service	Provides a task queue that is used by CM applications and services in a load-balancing environment to manage and distribute tasks.	Yes
Template Service	Enables the creation of new documents based on templates.	Activated, but path specifications are variable
URL Generator Service	Generates URLs for invoking applications and for accessing various kinds of resources.	Yes
URI Mapper Service	Maps URIs to GUIDs (Globally Unique Identifiers). It ensures that resources and pertinent metadata can be correctly retrieved even if their URIs change, for example, when documents are moved to another folder.	Yes
Virus Scanner Service	Used for virus checks.	Activated, but some configuration required.

Some other global services are used, but they are activated by default and do not require further configuration. They are therefore not visible in the Configuration iView. For a list of such services, see Internal Services.

Activities

To call up the overview for global services, choose Content Management ® Global Services from the Configuration iView.

Since the tasks performed by the different global services are quite varied, their configuration does not follow a common pattern. Some services cannot be configured. You can only activate or deactivate them. However, other services require you to specify configuration parameters.

After configuring some global services, you have to maintain the corresponding service permissions.

As is the case for repository managers, you can deactivate all global services if errors occur. To do this, remove the check in the Active checkbox in the configuration of the relevant global services. You can reactivate the service(s) when you have corrected the errors.
