adrci> 第二：查詢 adr home
adrci> show home
ADR Homes:
diag/clients/user_oracle/host_1874443374_80// 這個目錄用的不多，我不是很清楚。
diag/rdbms/orcl/orcl1//故障排除，查看alert等都在這個目錄，需要被設置成唯一目錄。第三設置唯一的adr home
adrci> set home diag/rdbms/orcl/orcl1
adrci> show home
ADR Homes:
diag/rdbms/orcl/orcl1第四：查詢alert日誌
adrci> show alert -tail 10 查詢最後十條。

Stopping background process VKTM或者：show alert -p "MESSAGE_TEXT like '%ORA-%'"
查詢ORA錯誤，從alert日誌裏把ORA錯誤提取出來。
第五：查詢incident：
adrci> show incident
ADR Home = /u02/app/oracle/diag/rdbms/orcl/orcl1:
*************************************************************************
INCIDENT_ID PROBLEM_KEY CREATE_TIME
-------------------- ----------------------------------------------------------- ----------------------------------------
156121 ORA 445 2016-12-09 18:02:58.877000 -05:00
1 rows fetched
incident簡介：
Incidents – the occurrence of each serious error (e.g. ORA-600, ORA-1578) causes an incident to be created.
Each incident is assignedan ID, and is described by a set of structured metadata.
諸如ORA-600錯誤的發生導致 incident被創建
每個incident 是個指定的ID，被一串 結構化的元數據描述。
第六：show problem
adrci> show problem
ADR Home = /u02/app/oracle/diag/rdbms/orcl/orcl1:
*************************************************************************
PROBLEM_ID PROBLEM_KEY LAST_INCIDENT LASTINC_TIME
-------------------- ----------------------------------------------------------- -------------------- ----------------------------------------
1 ORA 445 156121 2016-12-09 18:02:58.877000 -05:00
1 rows fetchedOracle將每次錯誤信息作爲一個INCIDENT，通過SHOW INCIDENT可以很方便的瞭解alert文件中包含所有的錯誤信息，以及發生的時間點。
而SHOW PROBLEM的結果更加清晰，它會根據Oracle的錯誤號，將相同的錯誤信息合併到一起(重複的incident)。通過這個結果，可以瞭解數據庫出現了哪些不同的錯誤信息。SHOW ALERT/INCIDENT/PROBLEM都支持條件篩選。
例如：
adrci> show incident -mode detail -p "PROBLEM_ID=1"
ADR Home = /u02/app/oracle/diag/rdbms/orcl/orcl1:
