Resolving ORA-481 and "terminating the instance due to error 481" (Doc ID 1950963.1)
ORA-00481 After "The instance eviction reason is 0x2" due to Lack of Ticket (Doc ID 1644015.1)
归根结底是RAC节点之间消息传输流量控制的问题，除网络、硬件原因外，需要打补丁解决。
以下为第一次处理前具体的alertlog。

针对这个RAC集群，做了加多的配置修正、优化，主要是如下所述。
◆数据库配置优化
0、前期大量的日志切换无法完成，导致数据库挂起，为此新增了loggroup，并删掉无用多余的logmember。
1、增大了ASM实例的内存，由350M--->2G
2、RAC并行进程强制在本地实例分配
3、为减少对性能的影响，关闭audit审计
4、AWR 资料保存时间由7天增加到30天
5、SGA增大10G至60G
◆修改网络相关的系统核心参数
/usr/sbin/no -p -o tcp_sendspace=4194304
/usr/sbin/no -p -o tcp_recvspace=4194304
/usr/sbin/no -p -o rfc1323=1
/usr/sbin/no -p -o sb_max=8388608
/usr/sbin/no -p -o udp_ephemeral_low=9000
/usr/sbin/no -p -o tcp_ephemeral_low=9000
◆修改内联网卡的参数
chdev -l en1 -a tcp_sendspace=1048576 -a rfc1323=1 -a tcp_recvspace=1048576
◆SWAP
物理内存大于 16GB，但 SWAP 空间低于 16 GB，不符合 Oracle 安装的标准建议。增大PS。chps -s 192 hd6
◆时区及时间确认，安全起见，暂不修改。
◆ntp确认，使用GI集群自身的时间同步，确保各个节点的时间同步，目前是几十秒的偏差，不是问题。
◆HA集群配置修改，当初安装集群时部分内容没有按照官方文档实施，本次做了补救，但不全面，可能仍存在未知的风险。
5月25日重启后，经多一段时间的观察，有所改善，但于6月7日9点又发生一次节点2当。
但此次已经不是节点的驱逐，说明上次的修正与配置优化起到了作用，初步断定与网络参数配置修改相关。日志如下，无evict日志。

针对此次的600内部错误，初步结论：
5月25日优化重启后，6月7日又发生过1次节点down的情况，经排查，基本确认是oracle BUG，在某些情况下会发生节点down。目前数据库PSU版本11.2.0.1.0，需要打补丁到最新版本11.2.0.1.6。后续需择机打补丁。
