This document applies to: Apptivity
Version and Release Number: 3.x
Error detection:
The Component Manager outputs:
** Server cannot send reply - connection closed **
with connections to an Oracle database
while running several applet clients at some point Component Manager
in an environment with 4 CM's, 1 DM and 120 applet clients
on Solaris against an Oracle database as data source.
Looking into the Oracle RDBMS log file shows up errors like
"too many open files"
Reason of the problem - resource bottleneck:
The console command ulimit -Sa shows the soft limit with nofiles as 64 .
Although the Distribution Manager and the Component Manager
don't use that much file descriptors there are a lot used by
the Oracle RDBMS. If the limit of nofiles is reached the server can't
communicate with the database anymore and the connection gets closed.
Solution:
Increasing the soft limit for nofiles in that specific
environment to 256 solved the problem.
