环境：

ORACLE10.2.0.4 64BIT

REDHAT 5.6 64BIT

AGENT 11.2.0.1 64BIT

打5759944补丁遇到：OPatch failed with error code 73

因为公司内使用EM11g作为整体的数据监控平台，所以在agent端agent是11g，而DB是10g所以在opatch的时候调用的是agent的目录，最终导致安装补丁失败：

OPatchSession cannot load inventory for the given Oracle Home /u01/oracle/product/10.2.0/db_1. Possible causes are:
No read or write permission to ORACLE_HOME/.patch_storage
Central Inventory is locked by another OUI instance
No read permission to Central Inventory
The lock file exists in ORACLE_HOME/.patch_storage
The Oracle Home does not exist in Central Inventory

ApplySession failed: ApplySession failed to prepare the system. OracleHomeInventory gets null oracleHomeInfo

OPatch failed with error code 73

解决办法是执行oracle数据库的重新定位：

[oracle@bi 5759944]$ ../../oui/bin/attachHome.sh
