Status: Unverified
FACT(s) (Environment):
Progress 9.1x
FACT(s) (Environment):
Windows
SYMPTOM(s):
Database background writers (APW, BIW and WDOG) do not auto start.
Database is started through ProControl / ProService.
A high value for the -B parameter is being used.
CAUSE:
With the database buffer pool, a certain amount of memory needs to be allocated. (See Progress Knowledge Base Solution 20183 to calculate the amount of memory.)
Sometimes this allocation will create a delay sufficient to produce a ProControl timeout. Since the behavior will vary across machines, it can be a trial and error process to determine the timeout limit.
FIX:
Decrease the database buffer pool size to prevent a timeout.
