Status: Verified
SYMPTOM(s):
Replication source database slows down during heavy database writes.
Terminating the Replication Server process causes performance to pick back up.
-pica set to maximum value of 256
Using fixed AI Extents
Ai and Bi blocksizes are set to 16.
FACT(s) (Environment):
Progress 9.1E
OpenEdge 10.1A
OpenEdge 10.1B
OpenEdge 10.0B
UNIX
Windows
CAUSE:
Bug# OE00131166
CAUSE:
As the DBService queue fills up, performance drops as Replication is unable to acknowledge notes.
FIX:
In replication enabled environments experiencing this issue, upgrade to 10.1A02, 10.1B01 and later versions then increase the -pica database startup parameter higher.
The new maximum value is 8192.
