Specifying a Master Index Checksum Length (Repository)

A checksum value is a number appended to the end of each EUID that allows systems to validate EUIDs to ensure accurate identification of records throughout the network. For detailed information about checksum values and how they work, see Manager Service Components (Repository) in Understanding Sun Master Index Configuration Options (Repository).

If you specify 0 (zero), checksum values are not used for validation. If the EUID length plus the checksum length is greater than 20, you need to increase the length of the EUID columns in the database creation scripts.

To Specify a Checksum Length

1. In the Projects window, expand the Configuration node in the project you want to modify, and then double-click the Threshold file.

2. Scroll to the second parameter element, ChecksumLength, in the EuidGeneratorConfig element.

3. Change the value of the parameter-value element to the desired length of the checksum value.

   For example:

   <parameter> <parameter-name>ChecksumLength</parameter-name> <parameter-type>java.lang.Integer</parameter-type> <parameter-value>2</parameter-value> </parameter>

4. Save and close the file.
