Weblogic product mode switching and JVM Switching

I. Product mode and development mode switch
The product mode and development mode are specified when the domain is created, rather than when weblogic is installed. So his configuration is in setDomainEnv. sh: find these two lines in setDomainEnv. sh: PRODUCTION_MODE = "true"
Export PRODUCTION_MODE
The development mode is PRODUCTION_MODE = "", and the product mode is PRODUCTION_MODE = "true"
 
Ii. 32bit JVM/64bit JVM
General we bin/exe format Weblogic installer only support 32bit. To install Weblogic support 64bit, ORACLE is provided in the form of wlsXXX-general.jar.
To replace 32Bit JVM with 64bit JVM, you need to change the value of BEA_JAVA_HOME or SUM_JAVA_HOME in setDomainEnv:
1. In CommEnv. sh
# Setup SUN_ARCH_DATA_MODEL
SUN_ARCH_DATA_MODEL = "32" = "SUN_ARCH_DATA_MODEL =" 64"
# JAVA_USE_64BIT, true if JVM uses 64 bit operations
JAVA_USE_64BIT = false = "JAVA_USE_64BIT = ture
2. the most important thing is to ensure that the native directory exists (the local library under the native directory is used for performance optimization, and the password does not display back), such as in linux: ${WL_HOME}/server/native/linux/i686 (32bit)
${WL_HOME}/server/native/linux/x86_64 (64bit)
I686 and x86_64 files are not the same, if not, you can copy a copy from somewhere else or through the java-jar wlsXXX-general.jar (in this case both directories have)
