Running the SubStringIndexTool
The SubStringIndexTool is used to create the schema objects associated with a substring index, and populate them with data from the source attribute. If the source attribute exists in a class that has subclasses, then the substring index contains information for all subclasses. The tool is run from a Windchill shell, using the following syntax:
windchill wt.pds.subStringIndex.SubStringIndexTool <operation> <user> <password> [<class name>] [<attribute name>]
where
• <operation> specifies the type of action to be performed on the substring index. For a complete list of available operations, see the following table.
• <user> and <password> are the credentials for a database installation user.
• <class name> and <attribute name> identify the object attribute for a substring index specified in the configuration file. If <class name> and <attribute name> are not specified, then the <operation> is applied to all substring index entries configured in the configuration file. The <class name> and <attribute name> arguments are optional.
The tool may take some time to complete, depending on the size of your database.
The SubStringIndexTool supports the following operations:
Operation
Description
create
Performs all operations necessary to make the substring index usable by the system, in the following order: config, table, build, and index.
* 
create is the only operation needed to create a substring index, and should be used in most cases. The other operations may be used individually if greater control is needed over managing the substring index.
config
Reloads configuration information in the method server.
build
Populates the substring index schema objects with data from the source attribute.
table
Creates the table schema object for the substring index.
index
Creates the index schema objects for the substring index.
sync
Manually synchronizes the substring index data with the associated source attribute values.
drop
Drops all schema objects for the substring index.
