Informix v7.x Problem on Digital Unix: 2GB Limit

We have 4GB's of data running on Informix V7.12.UC1 and Digital Unix ( V3.2C). One of the problem we discovered when we tried to transfer our data to a new DSS Server ( same box and OS ), is the size of data that Informix can support. The Informix Onunload utility to tape on Digital Unix is NOT working so we create a 4GB Unix file system, and successfully created a 3GB file to this UFS. However, we still CAN'T onunload a 4GB's of data . We found out that lseek() is hard-coded to the Informix utility and can only support up to 2GB's. We talked to DEC Support and they informed us that lseek() could support up to 128GB's. I know that someone has raised this same question about a 2GB limit on Informix and the TYPICAL answer is some OS's can't support anything above 2GB. Well, we certainly know that Digital Unix does not seem to have this problem. We've once again received the news that this is a known bug and will be fixed at the next release. I'm serious when I say that we cannot keep upgrading to fix basic data movement problems. We have for various bug related reasons, gone from V5.x, V6.x, and to a few different releases ( including the infamous UD1 release ) of V7.x. At every step, we've encountered problems and limitations on Informix utilities. I'm beginning to wonder whom besides us is doing the testing here. Does anyone have a good experience with this configuration that they could share with us, or help to overcome this particular problem? John Chantha chantha@tiac.net http://www.tiac.net/users/chantha
