1.开启 adrci
[oracle@xag112 ~]$ adrci
ADR base = "/u01/app/oracle"
adrci> show home
ADR Homes:
diag/rdbms/db112/DB112
diag/tnslsnr/xag112/listener
adrci> set home diag/rdbms/db112/DB112
adrci> show home
ADR Homes:
diag/rdbms/db112/DB112
2.显示所有问题
adrci> show problem
ADR Home = /u01/app/oracle/diag/rdbms/db112/DB112:
*************************************************************************
0 rows fetched
3.显示所有事件
adrci> show incident
ADR Home = /u01/app/oracle/diag/rdbms/db112/DB112:
*************************************************************************
0 rows fetched
4.跟踪alter 日志
#滚动显示 (类似tail -f alertlog一样)
adrci> show alert -tail -f

5.在control中设置的保留时间之后的日志
adrci> show control
ADR Home = /u01/app/oracle/diag/rdbms/db112/DB112:
*************************************************************************
ADRID SHORTP_POLICY LONGP_POLICY LAST_MOD_TIME LAST_AUTOPRG_TIME LAST_MANUPRG_TIME ADRDIR_VERSION ADRSCHM_VERSION ADRSCHMV_SUMMARY ADRALERT_VERSION CREATE_TIME
------------- -------------- ------------- -------------------- ----------------- ------------------ --------------- ---------------- ---------------- ----------------- -------------
2949729008 720 8760 2020-07-10 23:19:05 1 2 80 1 2020-07-10 23:19:05
#改trace files保留72小时
adrci> set control (SHORTP_POLICY = 72)
adrci> set control (LONGP_POLICY = 96)
#改incident file保留96小时
adrci> show control
ADR Home = /u01/app/oracle/diag/rdbms/db112/DB112:
*************************************************************************
ADRID SHORTP_POLICY LONGP_POLICY LAST_MOD_TIME LAST_AUTOPRG_TIME LAST_MANUPRG_TIME ADRDIR_VERSION ADRSCHM_VERSION ADRSCHMV_SUMMARY ADRALERT_VERSION CREATE_TIME

6.进入OS命令模式
adrci> host
[oracle@xag112 ~]$
[oracle@xag112 ~]$ pwd
/home/oracle
[oracle@xag112 ~]$ exit
exit
adrci>
