Howdy!
I am currently debugging a Performer 2.2 database paging routine for a radar
simulation running on an octane with 256MB of memory. I must be able to page
because already 20 geocells appear to be too much for loading/keeping into
memory. Eventually, the database will be > 200 geocells.
Currently, I am attempting load 5 geocells into memory and swap geocells as
the aircraft position changes. Even though the Performer remove and add
child routines are being applied reasonably, it doesn't appear to deallocate
memory correctly. I have added the calls to pfTmpDir and pfSharedArenaSize
after the first failures, and it holds up for a little while longer, but I
need a permanent solution and lasting fix.
I have noticed a simular problem while creating database loaders for
preprocessing other database formats, but made work arounds since these
utilities were not realtime anyway.
Please see attached routine.
