问题描述:

Ultra Search URL:
[url="http://localhost.localdomain:5620/ultrasearch"]http://localhost.localdomain:5620/ultrasearch[/url]
Ultra Search Administration Tool URL:
[url="http://localhost.localdomain:5620/ultrasearch/admin"]http://localhost.localdomain:5620/ultrasearch/admin[/url]
iSQL*Plus URL:
