oracle补丁p18841764相关

数据库版本：11.2.0.4.0

补丁要求环境：linux64（此处以该版本为例）

补丁注意事项：可以滚动升级。需要关闭该节点数据库，并关闭该节点的集群服务与相关进程。

补丁流程：

1、 unzip补丁包（建议路径为/u01）

2、关闭节点数据库与相关数据库资源

3、替换OPatch

4、进入补丁的路径下，opatch apply

常见错误处理：

Q1：有活动的lib包，不能进行补丁。

A1：有程序持有相关lib的句柄。lsof lib,找到持有该lib的句柄程序，关闭改程序即可。

Q2：补丁打完后，无法identify controlfile

A2：在rac环境下打该补丁必须关闭集群相关服务，若未关闭会引起asm注册的问题。在所有节点下执行

grid@pmsdb2:/u01/app/grid/product/11.2.0/db_1/bin$ ./setasmgidwrap -o /u01/app/oracle/product/11.2.0/db_1/bin/oracle

重新注册asm到oracle即可。

Q3：opatch版本过低

A3：下载p6880880补丁包，解压补丁后，替换ORACLE_HOME/OPacth

补充：未关闭asm情况下的，数据库启动日志关键部分如下
