Ioctl is probably a much faster way to check, but why not create the files as part of some other monthly process (12 months in advance even), checking anything a billion times for a onetime event seems a waste of cpu cycles.
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Simon Verona Sent: Monday, September 28, 2009 8:00 AM To: [email protected] Subject: Dynamically created Distributed files I have a transaction file which can get very large, and has the potential to blow through the 2gb file size limit (we are using jBase 3.4.10 on Windows platforms). The item id of the records in the file is [Internal Date].nn eg 15274.1 15274.2 etc. As such, I thought that I could split the file up into a distributed file with part files in the format TRANSACTION.FILE.MM.YY where MM is the calendar month, and YY is the calendar year and Part file numbers of MMYY Writing the algorithm for filing and retrieving the records is pretty straightforward (just an OCONV(INT(ID),'DM') and OCONV(INT(ID),'D2Y'). However, for each new month as the first record is written I will need to pre-create the data file before trying to retrieve any data from it. I'm therefore considering the best way of verifying whether the "Part" file actually exists and creating it if not. Is there a quicker way to do this than actually opening the file in the algorithm ? Is there a better way to achieve the same results? Thanks in advance.
