Status: Verified
FACT(s) (Environment):
Progress 9.1D
WebSpeed 3.1D
IBM AIX
SYMPTOM(s):
WebSpeed agents can not connect to more than 3 databases
AppServer can not connect to more than 3 databases
broker.server.log:
Maximum number of shared-memory segments per process exceeded. (1175)
_progres can connect to more than 3 databases
Using all Progress versions prior to 9.1D07
Java Version Build 1.3.1, J2RE 1.3.1 IBM AIX build ca1311-20011123a (JIT enabled: jitc)
WebSpeed agents/AppServers are connecting to database(s) in shared memory
WebSpeed agents/AppServer can connect to all databases when -S is specified
Variable EXTSHM is not set
Upgrading Java version 1.3.1 JVM to patch APAR IY33957 resolves the issue, but could not be performed at this time.
Connecting client/server mode to databases avoid the problem from occuring.
CAUSE:
Through thorough investigation, Progress development has deduced that the issue is specific to this jvm version, 1.3.1 not being able to connect to more then 3 shared memory segments and thus not a Progress related issue.
There are known problems on AIX with Java processes not being able to access more than 3 extents with 1.3.1 JVM.
FIX:
Revert back to Java 1.3.0 with ptf 9 or ptf 10.
