命令：opatch lsinventory用于查看数据库所打Patch的列表。但运行的时候发现错误：
[oracle@bej301441 OPatch]$ opatch lsinventory Invoking OPatch 11.1.0.6.2 Oracle Interim Patch Installer version 11.1.0.6.2 Copyright (c) 2007, Oracle Corporation. All rights reserved. Oracle Home : /u01/oracle/mc3yd213/db/tech_st/11.1.0 Central Inventory : n/a from : OPatch version : 11.1.0.6.2 OUI version : 11.1.0.7.0 OUI location : /u01/oracle/mc3yd213/db/tech_st/11.1.0/oui Log file location : n/a OPatch cannot find a valid oraInst.loc file to locate Central Inventory. OPatch failed with error code 104
解决方法：
原因是opatch在默认目录下找不到oraInst.loc文件，对于Unix系统来说oraInst.loc的默认位置是: /etc/oraInst.loc 或者 /var/opt/oracle/oraInst.loc 。
这里我们可以需要指定具体的oraInst.loc文件位置给opatch。
命令：opatch lsinventory -invPtrLoc /u01/oracle/mc3yd213/db/tech_st/11.1.0/oraInst.loc
（/u01/oracle/mc3yd213/db/tech_st/11.1.0为我数据库的ORACLE_HOME）
