Hi, We are using reports server and discoverer components of oracle 9ias for reporting. We are having two major problems. 1. The DAT file which stores all the report entries are getting corrupted and server does not come up and we loose all the reports when we create the new dat file to bring up the server. Product : Oracle Reports Developer Product Version : 9.0.2.2.0 Platform : HP-UX PA-RISC (64-bit) 2. Preference server crashes and we apply workaround to bring it up again. Product : Oracle Discoverer Product Version : 9.0.2.54.10 Platform : HP-UX PA-RISC (64-bit) Thanks, Manoj Kumar Email: manoj.g.kumar@xxxxxxxxxxx -- //www.freelists.org/webpage/oracle-l
