PQ51175: THE JIT DISABLED APPEARS WHEN THERE IS A JAVA_COMPILER=JITC IN THE CURRENT.ENV FOR THE SERVER. | |||||||||||||||||||||||||||||||||||||||||
![]() |
|||||||||||||||||||||||||||||||||||||||||
![]() APAR status Closed as program error. Error description If JAVA_COMPILER= is in the current.env file we turn disable the jit. Even if JAVA_COMPILER=jitc is used. This is incorrect. The documentation also states that any non blank value will turn the jit off and that is incorrect.Local fix If you want the jit enabled , remove the JAVA_COMPILER= parameter from the current.env file.Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: Environment Variable JAVA_COMPILER= * * is not working as documented. * **************************************************************** * RECOMMENDATION: * **************************************************************** JAVA_COMPILER= with nothing specified should enable the JIT compiler, but presently it disables it. When obtaining the JAVA_COMPILER environment variable, the loadAndInitVM routine does not handle the null string case. The null string case occurs when just JAVA_COMPILER= is specified in the current.env of the server.Problem conclusion Code has been changed to properly check for the various coding possibilities of the 'JAVA_COMPILER= ' Environmental Variable, in part bbolsys.cpp . APAR PQ51175 requires a change to documentation. NOTE: Periodically, we refresh the documentation on our Web site, so the changes might have been made before you read this text. To access the latest on-line documentation, go to the product library page at: www.ibm.com/software/webservers/appserv/ Document Name: WebSphere Application Server V4.0 for z/OS and OS/390: Installation and Customization Document Number: GA22-7834-01 On page 146, change the bullet on JAVA_COMPILER to read: JAVA_COMPILER. You do not have to specify JAVA_COMPILER at all, in which case the default is to set the JIT compiler on. If you use the environment variable, a null value (JAVA_COMPILER=) also turns the JIT compiler on. Any other value turns the JIT compiler off. APAR PQ51175 is associated with SERVICE LEVEL W400040 of WebSphere Application Server V4.0 for z/OS and OS/390.Temporary fix Comments
