TFA
- Trace File Analyzer Collector.
One of the biggest challenges for customers and support
engineers particularly when working Grid
Infrastructure (GI) and Real Applications Clusters (RAC)
issues is collecting pertinent data in a timely
fashion possibly across multiple nodes in a cluster. A big
part of this challenge is frequently the data
that is required is lost or overwritten, due to the diagnostic
collection not happening until sometime afterthe problem occurred.
For single Instance databases Automatic Diagnostic Repository (ADR)
does a good job of generating trace packages when a database
incident occurs, but ADR does not include
clusterware trace files and is currently not RAC aware. For
the clusterware the diagcollection tool
(diagcollection.pl) gathers all the logs when manually
requested to do so, and though this tool has proved to be useful,
it is run sometime after the problem has occurred and is generally
run to gather all possible logs without regard to their relevance
which can make the data set very large. Further it has to be run as
root across all nodes of a cluster which makes it more difficult to
manage from an operational perspective.
TFA Collector (from this point referred to as TFA) overcomes
some of these problems by running a
diagnostic JVM on each node in the cluster synchronized to
determine when diagnostic collection is
required (when enabled) as well as collecting and extracting
only the data that is pertinent to resolving the issue. TFA is
written outside of the GI/RAC/RDBMS product lines and as such could
be used for any
trace data, and is version and platform agnostic.
It is possible to limit the amount of space TFA will take up
for diagnostics by setting a maximum size.
TFA stores any metadata that it needs to persist in a Berkeley
Database (BDB) that is placed under the
TFA_HOME. The metadata for files and their events will be
stored until the file is physically deleted or
the directory it resides in is removed from TFA. TFA monitors
free space and will halt data collections
free space falls below 1GB in the TFA_HOME file system or the
repository hits its maximum repository
size.
上面是USER
GUIDE中的介绍，TFA会自动收集诊断信息，比diagcollection.pl收集更全和灵活，且是相关连收集。使用Berkeley
Database (BDB
文件数据库，嵌入式数据库)。安装环境支持大部分操作系统，只要安装bash
shell即可。
在安装11.2.0.4时执行root.sh后，会默认安装tfa,当然可以不安装。

由于tfa不随GI启动和关闭，
故在打patch时，需要先将其关闭
