Hard limits for "maximum open file descriptors"

安装Oracle 11g RAC之前的验证，报错如下：

Check: Hard limits for "maximum open file descriptors"

Node Name Type Available Required Status

---------------- ------------ ------------ ------------ ----------------

aaaaaaa2 hard 131072 65536 passed

aaaaaaa1 hard 4096 65536 failed

Result: Hard limits check failed for "maximum open file descriptors"

直接修改文件“/etc/security/limits.conf”，添加一行如下：

* hard nofile 131072

然后“ulimit -a”。再次验证，过。
