Oracle Online Patching报错"This is not a RAC setup. OPatch cannot determine the local node name"
问题描述
Oracle 11.2.0.4.0有一个BUG为
Bug 18034737 - Tracefiles from wxxx space management slave processes after upgrade to 11.2.0.4 (Doc ID 18034737.8)。
具体会一直产生trc文件，文件内容重复报错以下信息：
Segment does not exist or being held by someone else
对该bug可以忽略或打上对应的补丁。
由于BUG的补丁包可以在线打，当你online对所有节点打的时候
opatch apply online -connectString <SID_Node1>:<Username_Node1>:<Password_Node1>:<Node1_Name>,<SID_Node2>:<Username_Node2>:<Password_Node2>:<Node2_Name>,<SID_NodeN>:<Username_NodeN>:<Password_NodeN>:<NodeN_Name>
会报错如下信息：
This is not a RAC setup. OPatch cannot determine the local node name, but the value to "connectString" option has the node name. Please remove the node name if only local node is being patched. See help file for more details about "connectString" option.
解决方法
上网搜索报错信息目前是搜索不到的，但是opatch的写法是按照readme的规则来，没有任何问题。
于是从mos上边搜索，有这样两篇文档：
Fail to apply online patch to remote node with OPatch 12.2.0.1.14 (Doc ID 2433910.1)
OPatch: Behavior Changes starting in OPatch 12.2.0.1.9 and 11.2.0.3.16 releases (Doc ID 2232156.1)
根据Doc ID 2232156.1（从12.2.0.1.9版开始），当使用“ opatch apply”在RAC集群的RAC节点上应用补丁时，它将仅对本地节点应用补丁。群集中的其他节点。因此对于在线修补程序，如果在“ -connectString”中指定了远程节点，则OPatch命令将失败。
注意：
将在线修补程序应用于11.2时，在OPatch 11.2.0.3.16或更高版本上也会发生此问题。
请使用上面的apply / rollback命令来避免这种错误。
因此，这是一个由于OPatch版本问题必定发生的报错。我的OPatch版本是11.2.0.3.21因此对所有节点online patch的时候也会有这个错误。
由于无法对所有节点同时在线打补丁，因此只能一个节点一个节点的打，就没再次报错了。
opatch apply online -connectString <SID>:<USERNAME>:<PASSWORD>:

改为单个节点打：
opatch apply online -connectString qadb1:sys:qadbsys: [oracle@dev-rac01 18034737]$ opatch apply online -connectString qadb1:sys:qadbsys: Oracle Interim Patch Installer version 11.2.0.3.21 Copyright (c) 2020, Oracle Corporation.

之后对其他节点用同样的方法打上即可。
