Error description
Error Message: JVMSHRC157I Unable to allocate 419430400 bytes of shared memory requested Succesfully allocated maximum shared memory permitted (33554432 bytes) (To increase available shared memory, modify system SHMMAX value) . Stack Trace: N/A . N/A
Local fix
Use option -Xshareclasses:printStats to check the class debug area size. If the value is not desired, destroy the shared class cache and create a new one with -Xscmx value no greater than SHMMAX
Problem summary
This problem is caused when creating a non-persistent shared class cache and the value passed to -Xscmx is larger than SHMMAX
Problem conclusion
The JVM has been updated to change the class debug area size in proportion according to its original ratio to the -Xscmx value if the -Xscmx value is greater than SHMMAX. . This APAR will be fixed in the following Java Releases: 8 SR2 (8.0.2.0) 6 R1 SR9 (6.1.9.0) 7 R1 SR4 (7.1.4.0) 7 SR10 (7.0.10.0) .
