按网上说的 我查看配置文件 

else

        WLS_MEM_ARGS_64BIT="-Xms2048m -Xmx2048m"

        export WLS_MEM_ARGS_64BIT

        WLS_MEM_ARGS_32BIT="-Xms512m -Xmx512m"

        export WLS_MEM_ARGS_32BIT

fi

MEM_ARGS_64BIT="${WLS_MEM_ARGS_64BIT}"

export MEM_ARGS_64BIT

MEM_ARGS_32BIT="${WLS_MEM_ARGS_32BIT}"

export MEM_ARGS_32BIT

if [ "${JAVA_USE_64BIT}" = "true" ] ; then

        MEM_ARGS="${MEM_ARGS_64BIT}"

        export MEM_ARGS

else

        MEM_ARGS="${MEM_ARGS_32BIT}"

        export MEM_ARGS

fi

MEM_PERM_SIZE_64BIT="-XX:PermSize=512m"

export MEM_PERM_SIZE_64BIT

MEM_PERM_SIZE_32BIT="-XX:PermSize=128m"

export MEM_PERM_SIZE_32BIT

if [ "${JAVA_USE_64BIT}" = "true" ] ; then

        MEM_PERM_SIZE="${MEM_PERM_SIZE_64BIT}"

        export MEM_PERM_SIZE

else

        MEM_PERM_SIZE="${MEM_PERM_SIZE_32BIT}"

        export MEM_PERM_SIZE

fi

MEM_MAX_PERM_SIZE_64BIT="-XX:MaxPermSize=512m"

export MEM_MAX_PERM_SIZE_64BIT

MEM_MAX_PERM_SIZE_32BIT="-XX:MaxPermSize=256m"

export MEM_MAX_PERM_SIZE_32BIT

if [ "${JAVA_USE_64BIT}" = "true" ] ; then

        MEM_MAX_PERM_SIZE="${MEM_MAX_PERM_SIZE_64BIT}"

        export MEM_MAX_PERM_SIZE

各位 帮忙 看下 我该怎么设置 

不会吧，256M还不够？一般都是够的；

如果真不够，可以把

MEM_MAX_PERM_SIZE_64BIT="-XX:MaxPermSize=512m"

export MEM_MAX_PERM_SIZE_64BIT

MEM_MAX_PERM_SIZE_32BIT="-XX:MaxPermSize=256m"

export MEM_MAX_PERM_SIZE_32BIT

里面的调大一些，比如到784m和512m
