Continuing on this series, there are 2 commands which are very useful and we’ll see today: “events” and “changes”. Besides “set”, which we’ll cover too.

On the events command you will be able to drill down to a specific date and time, passing a specific component if needed as well you can check a database or instance as well. Using the last option you can, this is very useful when you want to see a history for the system and lists all important events in the system:

Usage : /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl events [-search <keyword> | -component <ASM|CRS> | -database <db_name> | -instance <db_instance_name> | -source <filename> | -from <time> -to <time> | -json | -fields all|<fields_list> ]
-component [ASM|CRS] Searches all ASM or CRS events
-database Searches all events from a particular database
-instance Searches all events from a particular instance
-source Searches all events from a particular alert file
-json Outputs event information in JSON format
-fields When provided with the -json option, the command will only return the requested fields
-from "Mon/dd/yyyy hh:mm:ss" From <time>
or "yyyy-mm-dd hh:mm:ss"
or "yyyy-mm-ddThh:mm:ss"
or "yyyy-mm-dd"
-to "Mon/dd/yyyy hh:mm:ss" To <time>
or "yyyy-mm-dd hh:mm:ss"
or "yyyy-mm-ddThh:mm:ss"
or "yyyy-mm-dd"
-for "Mon/dd/yyyy" For <date>
or "yyyy-mm-dd"
-last <n><h|d>

[root@servertst01 bin]# ./tfactl events -last 30d -database dbaseprd

[root@servertst01 bin]#

The “changes” command, this shows the changes in the system, as I did not have any changes made after the TFA was installed was not able to reproduce it here. It lists all changes in the system:

Usage : /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl changes [ -from <time> -to <time> | -for <time> | last <time_length> ]
-from "Mon/dd/yyyy hh:mm:ss" From <time>
or "yyyy-mm-dd hh:mm:ss"
or "yyyy-mm-ddThh:mm:ss"
or "yyyy-mm-dd"
-to "Mon/dd/yyyy hh:mm:ss" To <time>
or "yyyy-mm-dd hh:mm:ss"
or "yyyy-mm-ddThh:mm:ss"
or "yyyy-mm-dd"
-for "Mon/dd/yyyy" For <date>
or "yyyy-mm-dd"
-last <n><h|d>

Another way to see the changes in your environment is to use the search command passing a part to it and a specific component.

Hope it helps, there are still many scenarios of TFA which I would like to bring but not that much time, I will try to make long posts for the next ones. We´ll see.

Thanks for reading!

Hi all,

We are used to use adrci to manage our database logs right, if you don’t about adrci please check here and here.

But did you know that TFA can cleanup the CRS and database logs as well?

You might be thinking: 2 set of tools for the same job? Yyeah kind off… =)

Adrci is configurable and performs the purges per configured policy and tfactl managelogs will not. Also the tfactl managelogs will also clean the listener logs as well and you can clean all cluster logs from one node without having to connect to each server to execute the purge from adrci for example.

The cleanup can be done by database or GI which comes in handy as well.

You have a dry run option which will show what will be deleted and total freed space without actually deleting any files

Usage : /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl [run] managelogs [ -purge [[-older <n><m|h|d>] | [-gi] | [-database <all|d1,d2..>] | [-dryrun] ]] [ -show [usage|variation] [ [-older <n><d>] | [-gi] | [-database <all|d1,d2..>] ] ] [-node <all|local|node1,node2..>]

Options:
-purge           Purge logs
   -older        Timeperiod for log purge
   -gi           Purge Grid Infrastructure logs(all ADR homes under GIBASE/diag and crsdata(cvu dirs))
   -database     Purge Database logs (Default all else provide list)
   -dryrun       Estimate logs which will be cleared by purge command
-show            Print usage/variation details
   -older         Timeperiod for change in log volume
   -gi           Space utilization under GIBASE
   -database     Space utilization for Database logs (Default all else provide list)


 -older <n><m|h|d>  Files from past 'n' [d]ays or 'n' [h]ours or 'n' [m]inutes


e.g:
   /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl managelogs -purge -older 30d -dryrun
   /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl managelogs -purge -older 30d
   /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl managelogs -show usage

   /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl run managelogs -purge -older 30d -dryrun
   /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl run managelogs -purge -older 30d
   /oraadm/dba/ahf/oracle.ahf/tfa/bin/tfactl run managelogs -show usage

TFA also comes with a REST API which you can use POST and GET http which you need to setup prior usage, it will setup 2 users, tfaadmin and tfarest, and start a ORDS service on the server.

[root@servertst01 bin]# ./tfactl rest status

TFA REST Services is not running

[root@servertst01 bin]# ./tfactl rest start

TFA REST Services is not running

[root@servertst01 bin]# ./tfactl rest -start

Configuring TFA REST Services using ORDS :

This might take couple of minutes. Please be patient.

Adding Dependency Jars to ORDS

Adding users to ORDS :

Password must be at least 8 characters and contain a combination of Upper case and Lower case letters, numbers and one of [!@#%_]

Enter a password for user tfaadmin:
Confirm password for user tfaadmin:

Enter a password for user tfarest:
Confirm password for user tfarest:

Starting TFA REST Services

Successfully started TFA REST Services [PID : 158682]

TFA URL : https://servertest01:9090/ords/tfactl/print/status

COMPLIANCE URL : https://servertest01:9090/ords/tfactl/orachk/version

The commands are most like the ones from the CLI but using this REST API, you will receive JSON outputs which you can process and automate the use of TFA

Below are some examples

/tfactl/print/status

[root@servertst01 ~]$ curl -k --user tfaadmin:tfaadmin https://servertst01:9090/ords/tfactl/print/status

On the next ones I will do a review on a ORACHK and OSWatcher which are also part of the Autonomous Health Framework

I Hope it helps!

Hi all,

Another one for our series about Autonomous Health Framework:

Along with the AHF, we have some tools that we can take advantage of, one of them is OSWatcher. OSwatcher is a utility to capture performance metrics from the operating system using native OS tools for IO, network, CPU, memory, etc.

It gathers a snapshot of your system and stores it in a directory which you can then use it to parse the information there and perform a system wide analysis.

You can stop it if you want, out of the box it will gather OS information every 30 minutes

To see if it is running you can use tfactl toolstatus as below

[root@servertst01 bin]# ./tfactl toolstatus

[root@servertst01 bin]#

And to run a simple test you can call tfactl oswbb and it should parse all data in its archive directory BUT and I tried to do so I ran into a java out of memory error
I bumped the memory of the process up to 4G and still gor the same error.

If you want to try to increase your process memory you will need to edit the file oswbb.pm under oracle.ahf/tfa/ext/oswbb

You will see a line like below, and you will need to change the memory valeu to one that your system can handle, I´m not saying it will not work you can try.

system("$java -Xmx512M -jar $oswjar -i $adir @flags");

Here is the error:

I had over 4 days of data there, so by using the options -B and -E I was able to workaround the issue. If you are doing some troubleshooting I would advise to read 4 days of data anyway as we could be see averages and a spike could be reduced and not see in the analysis.
So it did not bothered that much.

Here when passing the date range I was able to execute the process as needed.

Hi all,

Here I am or another post on the Autonomous Health Framework series!

Based on previous posts, we now have the AHF installed, what can we do with it?
I would say a lot! Everything? I don’t think so.

I will post here what I usually use more on TFA and then I will focus on orachk (which is a monster on its own as well).

Imagine that you have a problem and need to gather different information from the OS and the Oracle Stack from different nodes?

That´s where TFA – Trace file analyzer comes into play. It will collect the data for you and if you run as its root. You can specify the component that you need if you need to drill down to a very specify issue.

Also when you have a Service request with MOS they will probably ask for it to be executed but if they don’t, you should do it and upload any way as it will save a lot of time to troubleshooting and back and forth messages.

And if you have Internet access, you can upload it using the TFA as well, see it here.
