Database Service Data Dictionary Views

You can query data dictionary views to find information about database services.

You can find information about database services in the following views:

    DBA_SERVICES

    ALL_SERVICES or V$SERVICES

    V$ACTIVE_SERVICES

    V$SERVICE_STATS

    V$SERVICE_EVENT

    V$SERVICE_WAIT_CLASS

    V$SERV_MOD_ACT_STATS

    V$SERVICEMETRIC

    V$SERVICEMETRIC_HISTORY

The following additional views also contain some information about database services:

    V$SESSION

    V$ACTIVE_SESSION_HISTORY

    DBA_RSRC_GROUP_MAPPINGS

    DBA_SCHEDULER_JOB_CLASSES

    DBA_THRESHOLDS

The ALL_SERVICES view includes a GLOBAL_SERVICE column, and the V$SERVICES and V$ACTIVE_SERVICES views contain a GLOBAL column. These views and columns enable you to determine whether a database service is a global service.
