OPatch在打补丁的过程中被中断，重新执行后报以下错误：
UtilSession failed: Lock file left by a different patch, OPatch will not try re-using the lock file. Log file location: /u11/app/oracle/product/11.2.0/dbhome_1/cfgtoollogs/opatch/14084247_Apr_16_2016_13_21_29/apply2016-04-16_13-21-29PM_1.log OPatch failed with error code 73
查看日志文件也报类似的错误。
原因是之前的opatch会话失败后，仍然在本地inventory上持有锁
解决方法：
1. Take a backup of $ORACLE_HOME/.patch_storage 2. Remove $ORACLE_HOME/.patch_storage/patch_locked % rm $ORACLE_HOME/.patch_storage/patch_locked 3. Create $ORACLE_HOME/.patch_storage/patch_free % touch $ORACLE_HOME/.patch_storage/patch_free 4. Verify that "opatch lsinventory" no longer reports the error % opatch lsinventory -detail
Lock file left by a different patch, OPatch will not try re-using the lock file.
