Attribute Indexes

Attribute indexes improve the performance of search algorithms. The script offers to index attributes. If you choose to do so, it will add indexes not only for Calendar Server, but also for Messaging Server and Communications Express. Therefore, once you have run the indexing for one product, you do not need to reindex for the other product. In deed, if you try to index the same attributes again, nothing happens. The script calls db2index for each attribute being indexed, but only if the index does not already exist.

The following table lists all the attributes the Directory Preparation Script indexes, grouped by suffix category. It also lists the type of indexes created for each attribute. For more information about Directory Server indexing, see http://docs.sun.com/coll/1316.1.

Suffix	Attributes Indexed	Type of Indexes Added
User/Group	`mail`	`pres,eq,approx,sub`
	`mailAlternateAddress`	`pres,eq,approx,sub`
	`mailEquivalentAddress`	`pres,eq,approx,sub`
	`member`	`eq`
	`cosspecifier`	`pres`

User/Group (for Access Manager – Schema 2)	`inetDomainBaseDN`	`pres,eq`
	`sunPreferredDomain`	`pres,eq`
	`associatedDomain`	`pres,eq`
	`o`	`pres,eq`
	`sunOrganizationAlias`	`pres,eq`

DC Tree (for Schema 1)	`inetDomainBaseDN`	`pres,eq`
	`inetCanonicalDomainName`	`pres,eq`

Personal Address Book (PAB)	`memberOfManagedGroup`	`pres,eq`
	`memberOfPAB`	`pres,eq`
	`memberOfPABGroup`	`pres,eq`
	`un`	`eq`
	`icsCalendar`	`pres,eq,approx,sub`
	`icsCalenarOwned`	`pres,eq,approx,sub`

New PAB	`displayname`	`pres,eq,sub`
	`MemberOfPiBook`	`eq`
	`MemberofPiGroup`	`eq`

Should you decide to add further indexes on your own, instructions for adding indexes can be found in the Directory Server documentation.
