About User-Defined Alphanumeric Sequences in Names

To apply a user-defined alphanumeric sequence to the Name_Format parameter of an instance, you must implement a Java function for the AlphaNumericSequence interface. This Java function replaces a user-defined pattern (for example, #key#) in the name_format parameter with the corresponding alphanumeric sequence.

• A serial number whose corresponding alphanumeric sequence is to be used to replace the user-defined pattern.

• The Java function must return a valid string, because the string is the instance name. For example, if the Name_Format parmeter maps to P_#key# and the alphanumeric sequence to be used is HH, then the function parameters are P_#key# and the serial number corresponding to HH.

• Place the Java function in the directory to which the environment variable CLIENT_CLASSPATH points. This directory is searched at startup. A Java class that implements the AlphaNumericSequence interface is found, and it uses the Java function throughout the design.
