> 现在的distribution/bin/seata-setup.sh文件里面默认是令JVM_XMX:="2048m"的然后也可以支持JVM参数注入(PR [#5529](https://github.com/apache/incubator-seata/pull/5529))，意思是要修改一下.sh文件使得能自动获得环境的内存值然后根据某种规则来适配JVM参数吗？还是只是单纯的获得参数 > > The current distribution/bin/seata-setup.sh file sets JVM_XMX:="2048m" by default, and it also supports JVM parameter injection (PR [#5529](https://github.com/apache/incubator-seata/pull/5529)). Does this mean we need to modify the .sh file to automatically obtain the memory value of the environment and then adapt the JVM parameters according to some rules? Or is it just about obtaining the parameters 目前已经可以通过参数注入方式，但是这样不够灵活，当未设置对应参数时只能使用默认值。所以我们需要设计一个合理的xms和xmx以及堆外内存占用在不同内存规格下的百分比，比如4g以下堆内存占用70% 以上则是75%之类的，每个不同的规格有不同的算法占比。 Currently we can inject JVM parameters, but that approach isn’t flexible enough: if a specific parameter isn’t set we fall back to a fixed default. We therefore need a policy to calculate reasonable Xms/Xmx settings and off-heap (direct/native) memory shares based on the host’s total memory. For example, use a heap of about 70% of total RAM for machines under 4 GB and about 75% for larger machines. Each memory tier should have its own percentage or calculation rule so the JVM options are derived automatically and adapt to different instance sizes. -- This is an automated message from the Apache Git Service.
