Configuration Properties
Info*Engine components use the attributes stored in LDAP directory entries for defining and maintaining configuration properties. Info*Engine component properties apply to an individual component, start with its runtime service name, and are read when the component is used.
For example, if you have defined a JNDI adapter with a runtime service name of “com.company.Ldap1,” the names of its configuration properties begin with “com.company.Ldap1.” Therefore, entering a value in a JNDI adapter’s Search Base field on the Property Administration form causes the com.company.Ldap1.searchBase property to be set.

The file paths shown in Info*Engine Property Administration utility examples use the slash (/) as the separator in filepaths even though the back slash (\) is the directory separator used on Windows systems. Info*Engine correctly identifies all system filepaths when you specify the slash. If you prefer to use the back slash for Windows filepaths, you must escape the back slash in the filepath. This means that you enter two back slashes (\\) for each back slash (\) in the path.

Using the runtime service name as a prefix allows all component properties to be loaded into memory without causing any confusion about which properties apply to which component. If a property with the same prefix is manually set multiple times, the value for the last property read is used. Because Info*Engine does not control the order in which the LDAP entries are read, the resulting value for a property that has been set multiple times is unpredictable.
Usually, you maintain one unique LDAP directory entry for each Info*Engine component. However, you can maintain common properties for multiple components in one LDAP service entry, and then include that LDAP entry in each component you want using the properties. The Info*Engine Property Administration utility provides the Additional Services section on forms for this purpose.
Info*Engine uses configuration properties in two ways:
• The properties are set when the component starts. For most components, you use an ie.properties file. The ie.properties file contains a seeAlso property that specifies LDAP information. This allows access control to be set on the file to avoid sensitive information from being seen through the use of a ps command.
• The properties are read when Info*Engine creates an instance of the component to process requests.
