RE: [U2] Help needed about the process being slow
1) Throttle the polling program so that it does not go out searching for information repeatedly, but rather waits 1-2 seconds between polls. 2) Put protections in place that will prevent the receiving program from attempting to open a file in progress from the sender. This may be as simple as attaching an extension to the file when it is being constructed, then after the file has been closed, rename it. This symptom just sounds like the two are fighting for the resources, and if that's true, these two ideas should help immensely. -Kevin [EMAIL PROTECTED] http://www.PrecisOnline.com -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ashish ratna Sent: Tuesday, July 13, 2004 8:10 AM To: [EMAIL PROTECTED] Subject: [U2] Help needed about the process being slow Hi All, We have a process (Universe program) which writes the records in a particular file (type 19). One of my C process is picking these records and processing them and the deleting them. If I run first process independently (C process stopped) it is very fast. Also if I have few records in the file and C process is running (Universe program stopped) this case C process works very fast. But the problem is that when I try to run both the programs simultaneously, the overall process becomes very slow. In terms of data- For writing 1800 records on a file by Universe it takes 3 min. (when C is not running) For processing 1800 records C process takes very less time (when universe is not running) But if both processes are running then it takes about 25 mins to complete the process. Can somebody tell me what could be the reason for this slowing down of process.

RE: [U2] Help needed about the process being slow
Hi, I've just tried something similar on UV/NT with no problems - until I pushed my external routine (scanning the directory and deleting the files as fast as UV writes them) into a tight loop that swallowed the processor. Then it all crawled, of course. Could there be anything in your C routine that would cause that kind of looping? Just a thought - if the C routine fails to open one of these files (e.g. if UV is still in process of writing it/holding it) how does your error trapping work? Do you loop until you can open it? If so, that might cause just that sort of loop, so that uv never gets a look in...

Ashish have you considered using many type 19 files, not one? Why not write each row as a seperate file ? I would think there is some kind of file-open contention going on and this is the source of your problem. Writing each row as a seperate file might correct that.
