For what it is worth... IMHO most functionality is easier to write, easier to read, and easier to debug with static code. So unless I have a good reason to prefer a dynamic approach for something I am coding I default to static.
No, it is not a min, max, avg thing.
In order, the numbers found in /proc/sys/kernel/sem map to SEMMSL, SEMMNS, SEMOPM, and SEMMNI.

Create a shortcut and in the properties use a command such as:
c:\openedge\bin\prowin.exe -1 -db dbname -p c:\appdir\startup.p
Where "prowin.exe" is the Progress client executable (prowin32.exe if you are on an old, crusty 32 bit release, _progres.exe if you are running a character...
for each oeel_index:
if not can-find( oeel where oeel.field1 = oeel_index.field2 ) then
Note: my WHERE clause is made up. I cannot make sense out of your example, it looks like it might have some typos in it. Or it might be that I'm just not much of a SQL guy.
Rob is correct. Your requirements are really quite vague and any advice we give will have to make far too many assumptions about what you are trying to accomplish.
If you are thinking that grouping deletions into a block and committing the set of deletions as one large transaction rather than...
Yes, that is a very workable technique. We used something very similar a few years ago with a customer that had a multi-terabyte db and who needed to setup a replication target at a remote datacenter (so no fast access shared filesystem available).
As you mentioned, pre-building and expanding...
There are various ways to do it but they all boil down to something like the following:
( Blocksize in bytes ) / ( average rows per block as shown by dbanalys ), then round up to the next power of 2
Example, 8k block average row size of 113:
8192 / 113 = 72; next power of 2 = 128 so put this...
I see that "exec returned 255" but it is unclear what exec was executing. Presumably some form of probkup is involved but it isn't clear what the command line was.
Do any of the .lg files contain any clues?
Probably not at all related except for the error number but I have very recently had a...
How does either approach accomplish the deletion of 300M records?
At one time, with certain (very old) Progress versions and poor disk hardware you could make a case that using 4GL programs and BUFFER-COPY could be faster than a binary dump and load because you can eliminate a lot of...
Ron has described the old style pessimistic swap reservation algorithm. To a degree this still used on Solaris, HPUX, and AIX. But Linux uses an “optimistic” reservation algorithm that assumes you won’t ever actually need much of that disk space. Linux is correct, you won’t.
Rob’s points about...
So you’re asking a new question about a different subject?
Instead of polluting a 13 year old thread with off topic rambling you should open a new thread specific to your actual question. Try to provide a clear explanation of what you are trying to accomplish, what resources you have, what you...
