The Oracle Unified Directory 11g Release 1 (11.1.1) software has some limitations that might affect the initial deployment of your directory server. Follow the recommendations for deployments in this section.
Administrators also should appropriately tune the Oracle Unified Directory directory server and its Java Virtual Machine (JVM) to ensure that adequately sized hardware is made available to support heavy write operations. For more information, see Chapter 6, Configuring the JVM, Java Options, and Database Cache, in Oracle Fusion Middleware Installation Guide for Oracle Unified Directory.
The Oracle Unified Directory directory server provides full LDAP v3 support, except for alias dereferencing, and limited support for LDAPv2.
To maximize performance when running the server as a proxy, you should restrict queries so that the proxy returns only the required attributes rather than all the attributes of an entry.
The directory server provides better performance when the database files are cached entirely into memory.
The default settings of the Oracle Unified Directory directory server are targeted initially at evaluators or developers who are running equipment with a limited amount of resources. For this reason, you should tune the Java virtual machine (JVM) and the directory server itself to improve scalability and performance, particularly for write operations. For more information, see Chapter 6, Configuring the JVM, Java Options, and Database Cache, in Oracle Fusion Middleware Installation Guide for Oracle Unified Directory.
If you want to import large LDIF files by using the import-ldif command, then it is recommended that you use the --skipDNvalidation option. However, if you are not certain that the LDIF file is valid, using this option is not advised.
