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
Maximum number of shared-memory segments per process exceeded. (1175)
_progres can connect to more than 3 databases
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
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:
Applying the latest jvm patch for 1.3.1, corrects the problem.
As per December 2003, after applying the patch, the version reported by 'lslpp -h Java131.rte.bin' should be 1.3.1.5.
The 'java -fullversion' command should show "J2RE 1.3.1 IBM AIX build ca131-20021102".
