Problem summary
On certain platforms and processors, the JVM now starts with large pages enabled by default for both the JIT code cache and the Java object heap, instead of the default operating system page size. On z/OS, the JVM uses 1M pageable large pages, when running on the IBM zEnterprise EC12 with the Flash Express feature (#0402), z/OS V1.13 with APAR OA41307, and the z/OS V1.13 Remote Storage Manager Enablement Offering web deliverable. Note: PAGESCM=ALL <HAT>00 NONE in the IEASYSxx parmlib member controls 1M pageable large pages for the entire LPAR. ALL is the default. The following sizes apply to Linux: Linux on x86 and AMD64/EM64T: 2 MB large pages Linux on System z: 1 MB large pages Note: These changes do not apply to Linux on IBM POWER? platforms. If the operating system is not configured for the large page size, or if the correct hardware is not available, the JVM uses the default operating system page size instead. You can configure the large page size using the -Xlp command. For more information about the -Xlp command, see JVM command-line options: http://publib.boulder.ibm.com/infocenter/java7sdk/v7r0/index.jsp ?topic=%2Fcom.ibm.java.zos.70.doc%2Fdiag%2Fappendixes%2Fcmdline% 2Fcommands_jvm.html.
