There are several types of properties in dbWatch.

  • Predefined properties are always present. For example, instances have properties called name and host.
  • Metadata properties are are manually assigned to particular objects in dbWatch (like instances or tasks).
  • Dynamic properties are properties that are dynamically defined for objects of a particular type.

Dynamic properties

Dynamic properties are defined in xml files located in the [dbWatch Server]/server/resources/properties/ catalog.

You cannot add files to this catalogue manually, but import them by placing them in the [dbWatch Server]/server/resources/import_area catalog.

This file contains properties in the following format:

  <value engine="sql">select VERSION from v$instance</value>
  <value engine="sql">select count(*) from v$session where status = 'ACTIVE' and username is not null</value>

The fields are

  • key : The name that identifies this property (used in dbwql queries).
  • compatability : DBWQL query that defines the database instances that this property is compatible with.
  • value : An SQL query that defines the property value.
  • valid-for : How long this property can be cached. Format xh/xm/xs, examples “24h”, “15m”, “60s”. (hours/minutes/seconds cannot be combined, so “1m 30s” is not allowed and must be written as “90s”).

Accessing properties

All properties can be queried using DBWQL, for example:
