Hi Louie, Answering your questions for better understanding-
(1) Yes Universe program is creating and writing to the file and then daemon process picks these records to process (2) C daemon deletes the record after processing it (3) Temporary files are there for very small duration of time, first of all C daemon selects the record names and then processes them one by one. While selecting the record name it encounters records with name DBnnn, but at the time of processing the record it is not able to find and open the record using fopen etc. in c program (may be because it is temporary record). And we are not able to see the record. We encountered such situation in our production environment where there is huge amount of data coming and being processed.

Is the uniVerse phantom creating + writing the file for the C daemon to process? 2. Is the C daemon deleting the file when it has finished processing it? 3. What do you see as a temporary file? Depending on your answers, we can make a better judgement call Louie -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of ashish ratna Sent: 01 July 2004 06:23 To: [EMAIL PROTECTED] Subject: [U2] UV Help needed Hi All, We are facing a problem of temporary file being generated in our application. Scenario is- One of our program is writing records in type 19 file. We have another C daemon process which reads these records from the file. Both of these processes are running continuously as phantom/daemon processes. But sometimes C daemon process encounters the temporary files with name like DBnnn (where nnn is some number). Since these are temporary files C process cannot open and process the data of this file. By the time C program tries to open this file, the file DBnnn is deleted and is not found in the directory. Has any body encountered similar situation? Is it due to the design that Universe and C programs are accessing the same file to read and write the data? Any pointers to resolve this problem are welcome.
