Oracleの/u01/11g/diag/rdbms/orcl/orcl/incident 的清理
https://docs.oracle.com/cd/E11882_01/server.112/e25494/diag.htm#ADMIN11007
每当一个错误发生的时候，oracle会创建一个incident，并且分配一个INCIDENT_ID号，同时在ADR HOME的INCIDENT目录中创建相应的INCIDENT 目录，每个错误号一个INCIDENT目录，目录被命名为incdir_<INCIDENT_ID>。在incident 目录下含有相应的DUMP文件。
清理过程：
登录Oracle用户
[root@ywsjoracle ~]# su - oracle [oracle@ywsjoracle ~]$
进入Oracle的bin目录
[oracle@ywsjoracle ~]$ cd /u01/11g/product/11.2.0/bin
进入adrci工具界面
[oracle@ywsjoracle bin]$ adrci ADRCI: Release 11.2.0.1.0 - Production on Tue Mar 5 09:39:22 2019 Copyright (c) 1982, 2009, Oracle and/or its affiliates. All rights reserved. ADR base = "/u01/11g"
查看Oracle目录，并重新设定路径
adrci> show home ADR Homes: diag/tnslsnr/ywsjoracle/listener diag/rdbms/orcl/orcl adrci> set homepath diag/rdbms/orcl/orcl adrci> show home ADR Homes: diag/rdbms/orcl/orcl
查看incident目录
adrci> show incident ADR Home = /u01/11g/diag/rdbms/orcl/orcl: ************************************************************************* INCIDENT_ID PROBLEM_KEY CREATE_TIME -------------------- ----------------------------------------------------------- ---------------------------------------- 948432 ORA 445 2018-03-15 10:58:31.459000 +08:00 948433 ORA 445 2018-03-15 11:17:50.442000 +08:00 948608 ORA 445 2018-03-15 16:10:12.935000 +08:00 948434 ORA 445 2018-03-15 16:17:57.916000 +08:00 948435 ORA 445 2018-03-16 09:59:34.706000 +08:00 948384 ORA 445 2018-03-16 10:35:49.098000 +08:00 948436 ORA 445 2018-03-16 10:39:00.805000 +08:00 948609 ORA 445 2018-03-16 10:51:03.735000 +08:00 948385 ORA 445 2018-03-16 11:05:42.751000 +08:00 948437 ORA 445 2018-03-16 11:37:55.445000 +08:00 948438 ORA 445 2018-03-16 11:58:09.025000 +08:00 948439 ORA 445 2018-03-16 12:22:35.600000 +08:00 948386 ORA 445 2018-03-16 14:40:46.873000 +08:00 1028260 ORA 445 2018-03-16 14:40:48.737000 +08:00 1028261 ORA 445 2018-03-16 15:31:23.096000 +08:00 1028262 ORA 445 2018-03-16 15:52:59.439000 +08:00 948387 ORA 445 2018-03-16 16:04:43.397000 +08:00 948424 ORA 445 2018-03-16 16:14:33.262000 +08:00 1028263 ORA 445 2018-03-16 16:16:59.289000 +08:00 948610 ORA 445 2018-03-16 16:48:29.259000 +08:00 954192 ORA 3137 [12333] 2018-03-17 00:05:00.377000 +08:00 956240 ORA 3137 [12333] 2018-03-17 00:08:08.466000 +08:00 950664 ORA 3137 [12333] 2018-03-17 00:24:00.919000 +08:00 954448 ORA 3137 [12333] 2018-03-17 00:54:42.599000 +08:00 948388 ORA 445 2018-03-19 10:15:38.856000 +08:00 948389 ORA 445 2018-03-19 11:21:44.250000 +08:00 948425 ORA 445 2018-03-19 15:31:44.082000 +08:00 1028264 ORA 445 2018-03-19 15:31:59.897000 +08:00 948390 ORA 445 2018-03-19 17:06:35.034000 +08:00 1028265 ORA 445 2018-03-19 17:08:34.715000 +08:00 1028266 ORA 445 2018-03-20 09:00:25.083000 +08:00 1028267 ORA 445 2018-03-20 09:33:54.698000 +08:00 948391 ORA 445 2018-03-20 09:48:54.298000 +08:00 1028272 ORA 445 2018-03-20 09:51:53.383000 +08:00 1028273 ORA 445 2018-03-20 09:58:28.477000 +08:00 1028277 ORA 445 2018-03-20 10:24:33.673000 +08:00 1028274 ORA 445 2018-03-20 10:33:52.754000 +08:00 1028278 ORA 445 2018-03-20 10:49:34.743000 +08:00 1028275 ORA 445 2018-03-20 10:51:43.937000 +08:00 1028279 ORA 445 2018-03-20 10:56:01.555000 +08:00 1028276 ORA 445 2018-03-20 11:04:12.931000 +08:00 1028280 ORA 445 2018-03-20 11:10:43.473000 +08:00 1028285 ORA 445 2018-03-20 11:15:54.297000 +08:00 948426 ORA 445 2018-03-20 11:28:54.552000 +08:00 1028286 ORA 445 2018-03-20 11:31:25.308000 +08:00 1028287 ORA 445 2018-03-20 11:55:14.281000 +08:00 1028288 ORA 445 2018-03-20 14:43:51.694000 +08:00 958496 ORA 3137 [3120] 2018-03-21 02:23:04.994000 +08:00 1028314 ORA 445 2018-03-22 09:31:01.833000 +08:00 1028302 ORA 445 2018-03-22 09:32:10.803000 +08:00 First 50 rows fetched (*** more available ***)
