Sorry, I had sent an email with Japanese code just a moment ago. Send it again. ------- Hello I will continue to test the OpenLDAP+Oracle10g. BTW, two questions do not relate to Oracle10g. 1. Are the current sorted tables (for example, the tables in backsql_create.sql and testdb_create.sql) the best tables with performance? 2. Does other sort method with good ldapsearch performance exist? Best regards Pu
