Awe window size where is it




















Note: If you are on Release 9. Note: Recall from the earlier section that these errors may also occur if you are trying to start up with a buffer cache that is too large for the physical memory available. Note: The same errors above have also been observed with a buffer cache that is too small. If you attempt to start up with a buffer cache that is too small i.

Therefore, if you go through the above calculations, and the instance still does not start, try adding an additional 10 Meg or so to the calculated value. Note: Also, keep in mind that when calculating the of CPUs in the system, you have to take hyperthreading into account. On a hyperthreaded system, the OS will think that you have double the of CPUs in the system over what you actually have, and this is the number that must be used in the calculations.

Really Friendly and efficient staff, great price and great service. So very pleased with the result.

Whole house installation replacing wood timber sashes with upvc double glazed sash windows. Very pleasant to do business with. Great communication, excellent fitter and really pleased with the finished product. More and more of our street are turning to All Weather Exteriors due to the word of mouth recommendations and the brilliant product. Would highly recommend.

The work was carried out by John, who did a great job and made quick progress it was particularly good that the windows could be fitted from inside the flat on the first floor without any need to bother the neighbours. This would also require the object to be locked in memory while in use - again, bang goes your transparency. Assuming you can get a 64 bit version of Delphi now you might be better off going to a 64 bit version of Windows for customers that need more RAM.

You state that you do not want to move to a database, but what about a database that specifically uses AWE? I've not tried it personally, but would consider using products from this company for my own projects. Basically, a range of addressable memory is reserved, and the memory outside the addressable range is then mapped to the addressable range when needed, and unmapped when no longer need, allowing other memory to be mapped at the same addresses.

Thereby most non-AWE aware data structures or containers wouldn't work in such a scenario - probably a TMemoryStream descendant is easier to build. It should be easy enough to build a TList or the like that store data in AWE memory, it should keep track where the data are really stored and recall them when needed, adjusting addresses as well when data are mapped to addressable memory. I am not aware of any Delphi containers library using AWE, and there is another issue: desktop 32 bit operating systems can't use more than 4GB of physical RAM, a server version would be required, and the supported physical RAM depends on what version is used, see here for a complete list.

The database can be created as an in-memory only DB and will then not need any further harddrive access while manipulating.

Your situation sounds similar to ours, our application uses a huge datafile that we store in a memory-mapped file. The files are around MB, and we allocate data structures from them that use up to 1. You could try memory-mapped files with a sliding window, meaning you dynamically create views of different chunks of the file depending on what part of it the application is using.

Sounds like that won't work though because you need the entire file in memory at once. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Thanks Patrick, I think! If you are were willing to share some mor e detail on the basic techniques that would be great, but looking at your product I can tell that this is the crown jewels so it's understandable that you stay tight lipped. Just as an aside, what you're doing with your product is very similar to what we're doing, and I'm going to make it even less likely that you'll share now! Years ago I was a customer of a far sigthed MRP tool provider processing data in this manner, I've forever since tried to use such techniques.

The problem as you know only too well is memory space. All well and good when the host data is small and can fit inside the 3Gb limit or 4 on WoW. We started our tool with the aim of addressing small customers only.

However, we've been tackling increasing large customers over the 2 - 3 years and are now always banging our head on the 3Gb limit.
