oraInventory目录的作用

What is oraInventory ?oraInventory is repository (directory) which store/records oracle software products & their oracle_homes location on a machine. This Inventory now a days in XML format and called as XML Inventory where as in past it used to be in binary format & called as binary Inventory.
There are basically two kind of Inventory Global Inventory (also called as Central Inventory) and Local Inventory also called as Oracle Home Inventory.

oraInventory中记录了oracle安装目录的相关信息，通常在oracle软件安装过程中会自动创建，路径通常会在/oracle_base/oraInventory/，并在/etc/oraInst.loc中记录相关的路径信息，有时候我们的oracle目录是从另一套相似环境中tar过来的，这个时候是不会有oraInventory信息，如果此时数据库需要升级，或者打psu，那么会报错

这时候就需要我们重建oraInventory信息，创建步骤如下：

step 1:编写/etc/oraInst.loc

[root@ORACLE11g-dg etc]# vim oraInst.loc

inventory_loc=/u02/oraInventory
inst_group=oinstall

step 2:运行runInstaller命令进行oraInventory重建工作

[oracle@ORACLE11g-dg database]$  ./runInstaller -silent -ignoreSysPrereqs -attachHome ORACLE_HOME="/u02/oracle/11.2.0/dbhome_1"

ORACLE_HOME_NAME="ORA11g"

Starting Oracle Universal Installer...

step 3:opatch 命令验证可用性

[oracle@ORACLE11g-dg OPatch]$ ./opatch lsinventory
Invoking OPatch 11.2.0.1.7

step 4:进入相关目录产看相关文件内容
