ADRCI工具是Oracle11g才推出的新工具，主要用来管理alert文件、trace文件、dump文件、健康监事报告等。
这一篇简单介绍ADRCI工具。
用过11g的人都会发现，11g中alert文件以及trace文件的存放位置都发生了变化。从原来的ORACLE_BASE/admin/INSTANCE_NAME目录变成了ORACLE_BASE/diag/rdbms/DBNAME/INSTANCE_NAME目录。
Oracle之所以修改了这个跨越多个版本都没有修改过的参数设置，就是因为Oracle在11g中推出了ADRCI。这个工具可以统一管理ASM实例和多个数据库实例的alert文件、后台trace文件、用户trace文件，dump文件等等。
而且这个工具可以快速查询错误相关的所有trace文件，并将这些文件打包到一个zip文件，以便将问题相关的信息提供给Oracle的技术支持。
看一下ADRCI工具的简单命令：

adrci> HELP IPS ADD
Usage: IPS ADD
[INCIDENT <incid> | PROBLEM <prob_id> | PROBLEMKEY <prob_key> |
SECONDS <seconds> | TIME <start_time> TO <end_time>]
PACKAGE <package_id>
Purpose: Add incidents to an existing package.
Arguments:
<incid>: ID of incident to add to package contents.
<prob_id>: ID of problem to add to package contents.
<prob_key>: Problem key to add to package contents.
<seconds>: Number of seconds before now for adding package contents .
<start_time>: Start of time range to look for incidents in.
<end_time>: End of time range to look for incidents in.
Example:
ips add incident 22 package 12
adrci> HELP SHOW PROBLEM
Usage: SHOW PROBLEM [-p <predicate_string>]
[-last <num> | -all]
[-orderby (field1, field2, ...) [ASC|DSC]]
Purpose: Show the problem information. By default, this command will
only show the last 50 problems.
Options:
[-p <predicate_string>]: The predicate string must be double-quoted.
The field names that users can specify in the predicate are:
PROBLEM_ID number
PROBLEM_KEY text(550)
FIRST_INCIDENT number
FIRSTINC_TIME timestamp
LAST_INCIDENT number
LASTINC_TIME timestamp
IMPACT1 number
IMPACT2 number
IMPACT3 number
IMPACT4 number
SERVICE_REQUEST text(64)
BUG_NUMBER text(64)
[-last <num> | -all]: This option allows users to either select
the last <num> of qualified problems to show or to show all the
qualified problems. If this option is not specified, this command
will only show 50 incidents.
[-orderby (field1, field2, ...) [ASC|DSC]]: If specified, the results
will be ordered by the specified fields' values. By default, it will be
in the ascending order unless "DSC" is specified. Note that the field
names that can be specified here are from the "PROBLEM" relation.
Examples:
show problem
show problem -p "problem_id>123"

除了上面交互式的方式外，还可以调用脚本，或者指定一系列命令来批量执行命令：
C:Documents and Settingsytk>adrci -help
Syntax:
adrci [-help] [script=script_filename]
[exec = "one_command [;one_command;...]"]
Options Description (Default)
-----------------------------------------------------------------
script script file name (None)
help help on the command options (None)
exec exec a set of commands (None)

比如：
C:Documents and Settingsytk>adrci exec="show base;show home;set home diagrdb
msytk1110ytk1110;show home"
