This preface lists changes in the Oracle Autonomous Health Framework Checks and Diagnostics User's Guide 20.2.
Resource Savings Through Fewer Repeat Collections for Similar Issues
Flood control avoids unnecessary repeat collections for similar events and helps conserve system resources.
The flood control limit instructs Oracle Trace File Analyzer to only collect a certain amount of times for the same event and then pause collection for that event for a set duration.
Limit Oracle Trace File Analyzer's CPU Usage
On Linux the CPU usage of Oracle Trace File Analyzer can be limited with the
tfactl setresourcelimit [-value
For example to limit Oracle Trace File Analyzer to a maximum of 50% of a single CPU
tfactl setresourcelimit -value 0.5
CPU resource limits for Oracle Trace File Analyzer can be set between a minimum of 0.5 and maximum of 4 or 75% of available CPUs, whichever is lower. By default, the Oracle Trace File Analyzer CPU limit is set to the maximum.
Easier to Upload Diagnostic Collections
tfactl setupload -name config_name
-type config_type can be used to configure where diagnostic
collections from Oracle Trace File Analyzer, Oracle ORAchk, and Oracle EXAchk are
Collection configurations can also be used on-demand using
upload. Multiple upload configurations can be stored by giving them unique
tfactl setupload -name mysqlnetconfig -type sqlnet
Oracle Trace File Analyzer will then prompt you for the required values.
setupload, you can also use:
tfactl getupload -name config_nameto retrieve all values
tfactl checkupload -name config_nameto check if the values can be used to make a connection to the resource
tfactl unsetupload -name config_name [-parameter parameter | -all]to unset one or all the values for the configuration
Latest Most Secure Python Stack
The Python stack has been upgraded to 3.7.7.
This upgrade avoids all known Python security issues.
Run All Database Server Compliance Checks Without Needing root Password
All complaince checks can now be run on the database server without
Oracle ORAchk root checks can be passed to the Oracle Trace File Analyzer root
daemon for excution as
root. This means as a DBA you can now run all
checks without requiring the
Integration of Oracle DBSAT into Oracle Autonomous Health Framework
DBSAT is a lightweight utility that will not impair system performance in a measurable way.
Integration of AutoUpgrade utility into Oracle Autonomous Health Framework
The AutoUpgrade utility identifies issues before upgrades, performs pre- and postupgrade actions, deploys upgrades, performs postupgrade actions, and starts the upgraded Oracle Database.
