1.修改weblogic自己的内存：
位置：Oracle/Middleware/wlserver_10.3/common/bin下的文件
commEnv.sh：
if [ "$PRODUCTION_MODE" = "true" ]; then
case $JAVA_VENDOR in
Oracle)
JAVA_VM=-jrockit
MEM_ARGS="-Xms128m -Xmx256m"
;;
HP)
JAVA_VM=-server
MEM_ARGS="-Xms32m -Xmx200m -XX:MaxPermSize=128m"
;;
IBM)
JAVA_VM=
MEM_ARGS="-Xms32m -Xmx200m"
;;
Sun)
JAVA_VM=-server
MEM_ARGS="-Xms4g -Xmx8g -XX:MaxPermSize=2g"//根据自己的jdk选择修改：4g---8g，
;;
Apple)
JAVA_VM=-server
MEM_ARGS="-Xms32m -Xmx200m -XX:MaxPermSize=128m"
;;
*)
JAVA_VM=
MEM_ARGS="-Xms32m -Xmx200m"
;;
esac
else
case $JAVA_VENDOR in
Oracle)
JAVA_VM=-jrockit
MEM_ARGS="-Xms128m -Xmx256m"
JAVA_OPTIONS="${JAVA_OPTIONS} -Xverify:none"
;;
HP)
JAVA_VM=-client
MEM_ARGS="-Xms32m -Xmx200m -XX:MaxPermSize=128m"
;;
IBM)
JAVA_VM=
MEM_ARGS="-Xms32m -Xmx200m"
;;
Sun)
JAVA_VM=-client
MEM_ARGS="-Xms4g -Xmx8g -XX:MaxPermSize=2g"
JAVA_OPTIONS="${JAVA_OPTIONS} -Xverify:none"
;;
Apple)
JAVA_VM=-client
MEM_ARGS="-Xms32m -Xmx200m -XX:MaxPermSize=128m"
;;
*)
JAVA_VM=
MEM_ARGS="-Xms32m -Xmx200m"
;;
esac
fi
export JAVA_VM MEM_ARGS JAVA_OPTIONS
2.jdk内存的配置
位置：Middleware/user_projects/domains/base_domain/bin
修改setDomainEnv.sh
if [ "${JAVA_VENDOR}" = "Sun" ] ; then
WLS_MEM_ARGS_64BIT="-Xms4g -Xmx6g"
export WLS_MEM_ARGS_64BIT
WLS_MEM_ARGS_32BIT="-Xms4g -Xmx6g"
export WLS_MEM_ARGS_32BIT
else
WLS_MEM_ARGS_64BIT="-Xms512m -Xmx512m"
export WLS_MEM_ARGS_64BIT
WLS_MEM_ARGS_32BIT="-Xms512m -Xmx512m"
export WLS_MEM_ARGS_32BIT
fi
ps：jdk默认是sun的，其他的根据需求配置
