What the Installation Must Do

Applications that extend the schema, must apply updates as described in the following procedure.

ms677994.wedge(en-us,VS.85).gifTo apply updates when extending the schema

  1. Add the new attributes.
  2. Add the new classes.
  3. Add the new attributes to classes.
  4. Trigger a cache reload.

New attributes referenced in Step 3 must be referred to by its OID because the new attribute name is not present in the schema cache at this point.

Step 4 is unnecessary if the extensions will not be used immediately; the extensions will appear in the schema cache in approximately 5 minutes, depending on system load. For more information about the schema cache and how to trigger a cache reload, see Updating the Schema Cache.
