AHF简介
1.AHF的诞生就是为了与时俱进，让DBA们收集系统日志以及故障日志更加快捷，同时让Oracle也能够快速定位问题并提供对应的解决方案，号称是每个DBA必备工具。
2.AHF现在默认绑定在DB12+以及GRID12+的RU中，同时最新的版本也可以通过patch:30166242获取，其对应RU与AHF版本历史如下：

4. AHF使用非root（必须使用 Oracle home的owner账户，如oracle或者grid等）时，以下功能不具备
Automate diagnostic collections
Collect diagnostics from remote hosts
Collect files that are not readable by the Oracle home owner, for example, /var/log/messages, or certain Oracle Grid Infrastructure logs
To install as the Oracle home owner, use the –ahf_loc option ./ahf_setup -ahf_loc install_dir

AHF使用
The new ahf command combines functionality from pre-existing as well as new AHF component CLIs into a single easy to understand command.
Previously, AHF included many components, each with their own command line. This has made it difficult for user to use different features of AHF.
This release begins the unification of all AHF components under a single command line
ahf <category> <action> [<options>]
Where categories are:
configuration - for changing AHF configuration
security - for security related configuration
collection - for capturing diagnostic data
analysis - for analyzing an environment for problems and providing recommendations for corrective action
software - for modifying the install software patching, upgrading or uninstalling
schedule - for scheduling automated tasks
observer - for viewing potential problems captured by AHF
Unification of commands will continue in future releases. Pre-existing commands continue to be supported.
For more information, see the AHF User's Guide section on Unified Command-Line Interface for the Entire AHF Stack .
