Is your Oracle database in need of some TLC? Then you need ORAchk (Oracle Check). The utility examines an Oracle system’s configuration looking for areas that need improvement and generates a risk report that you can then use to improve the health status of your database. ORAchk is provided as part of Oracle’s Autonomous Health Framework (AHF) toolkit.

I see a lot of customers looking to take advantage of the benefits that ORAchk brings so I thought I’d write a step-by-step guide on how to install Oracle AHF, and run ORAchk, on Linux and Windows environments.

  1. Pre-requisites
  2. Oracle AHF and ORAchk on Linux
  3. Oracle AHF and ORAchk on Windows

Pre-requisites

Before you begin the installation there are some pre-requisites to installing Oracle AHF and running ORAchk. I’ve outlined the key pre-requisites below:

 

Linux
  • Oracle AHF should be installed as root to obtain the fullest capabilities. If you are unable to install as root then Oracle AHF should be installed as the Oracle Home User.
  • Oracle AHF should be installed to a filesystem with at least 5GB of free diskspace.
  • Perl version 5.10 or later is required to install Oracle AHF.
Windows
  • Oracle AHF should be installed as a user with local administrative privileges.
  • Oracle AHF should be installed to a disk with at least 5GB of free diskspace.
  • Perl version 5.10 or later is required to install Oracle AHF (note that a later version of Perl is usually to be found installed in the %ORACLE_HOME%\perl directory)

Installing Oracle AHF on Linux

So you’ve checked the pre-requisites and you’re good to begin the installation. The latest version of Oracle AHF can be downloaded as a .zip file from Oracle Support via the following link:

Oracle Autonomous Health Framework (AHF) – Including TFA and ORAchk/EXAchk (Doc ID 2550798.1)

You will need to ensure that the GA Release of TFA & ORAchk/EXAchk for Linux is downloaded.

Once downloaded, transfer the .zip file (using e.g., FileZilla, WinSCP or pscp) to the database host as the root user and unzip the file. Ensure that there is at least 5GB of free diskspace on the filesystem where the Oracle AHF will be installed.

In the following example the AHF-LINUX_v20.1.1.zip file has been transferred to the /opt/oracle/media/ahf directory:


[root@dbhost]# pwd 
/opt/oracle/media/ahf 
 
Check available diskspace 
[root@dbhost]# df -hP . 
Filesystem            Size  Used Avail Use% Mounted on 
/dev/mapper/ol-root   100G   42G   58G  42% / 
 
[root@dbhost]# ls -lh 
total 349M 
-rw-r--r--. 1 root root 349M Mar 19 13:06 AHF-LINUX_v20.1.1.zip 
 
Unzip the AHF-LINUX zip file 
[root@dbhost]# unzip AHF-LINUX_v20.1.1.zip 
Archive:  AHF-LINUX_v20.1.1.zip 
  inflating: README.txt 
  inflating: ahf_setup 
 
[root@dbhost]# ls -lh 
total 703M 
-rw-r--r--. 1 root root 349M Mar 19 13:06 AHF-LINUX_v20.1.1.zip 
-rwxr-xr-x. 1 root root 355M Mar 17 20:29 ahf_setup 
-rw-r--r--. 1 root root  832 Mar 17 20:33 README.txt 
Check that perl v5.10 or later is installed on the server. In this example perl v5.16 is installed: 

[root@dbhost]# yum list installed | grep -i perl.x86_64 
perl.x86_64                             4:5.16.3-294.el7_6 

If perl is not installed or is an earlier version, use ‘yum install perl.x86_64’ to install.

To install Oracle AHF we run the ahf_setup installer with the -extract parameter. We also specify the -notfasetup parameter to avoid enabling the Oracle Trace File Analyser component of Oracle AHF.

By default Oracle AHF will be installed to the /opt/oracle.ahf directory.


[root@dbhost]# pwd 
/opt/oracle/media/ahf 
 
[root@dbhost]# ./ahf_setup -extract -notfasetup

Running ORAchk on Linux on non-RAC Databases

Now that Oracle AHF has been installed we can run ORAchk from the ‘bin’ directory below the Oracle AHF installation directory:


[root@dbhost]# cd /opt/oracle.ahf/bin
[root@dbhost]# ./orachk
Note the following message will be seen if Oracle ASM storage is utilised

Running ORAchk on Linux on RAC Databases

There are 3 methods of running ORAchk in a clustered database environment:

Option 1: If password-less SSH user equivalency for root has been setup (allowing the root user to SSH to the remote nodes without having to enter a password) then ORAchk can automatically execute the checks on the remote nodes.

Option 2: If password-less SSH user equivalency for root has not been setup then the root password for the remote nodes can be specified at the time of running ORAchk. Temporary password-less SSH user equivalency will be configured for the duration of ORAchk’s execution.

Option 3: The ORAchk command-line option – localonly can be used to run ORAchk on the local node only. If this option is chosen then Oracle AHF should be installed on all cluster nodes and ORAchk should be run individually on each node

Check to see if password-less SSH user equivalency for root has already been set up:


Example where password-less SSH user equivalency has not been setup 

[root@dbhostrac1]# ssh dbhostrac2 

root@dbhost2’s password: ***********  /* Note – if we are prompted to enter a password here then equivalency 
                                         does not exist. In this case we will need to manually enter root’s 
                                         password when running ORAchk */ 

Example where password-less SSH user equivalency has been setup 

[root@dbhostrac1]# ssh dbhostrac2 

Last login: Wed Mar 25 16:35:50 2020  /* Note – if we are not prompted to enter a password here then  
                                         equivalency exists and ORAchk can automatically use ssh to execute 
                                         checks on the remote nodes */ 

As before, ORAchk is run from the ‘bin’ directory below the Oracle AHF installation directory. In the following example password-less SSH user equivalency for root has been setup (option 1 above)

[root@dbhostrac1]# cd /opt/oracle.ahf/bin 

[root@ dbhostrac1]# ./orachk 

Clusterware is running from /u01/app/18.0.0/grid. Is this the correct Clusterware Home?[y/n] y

Installing Oracle AHF on Windows

If you’re looking to install Oracle AHF on Windows you can download the latest versionfind tas a .zip file from Oracle Support via the following link:

Oracle Autonomous Health Framework (AHF) – Including TFA and ORAchk/EXAchk (Doc ID 2550798.1)

You will need to ensure that the GA Release of TFA & ORAchk/EXAchk for Windows (64-bit) is downloaded.

Note that, as of the time of writing, the .zip file downloaded from Oracle Support contains a directory named ‘..’ as highlighted in the screenshot below:

This causes some issues when the contents of the .zip file are extracted so it is recommended to open the .zip file using 7-Zip and rename the ‘..’ directory to e.g., ‘extracted’ before proceeding:

Once downloaded, transfer the .zip file to the database host as an administrative user and unzip the file. Ensure that there is at least 5GB of free diskspace on the disk where the Oracle AHF will be installed.

In the following example the AHF-Win_v20.1.1.zip file is transferred to the D:\Oracle\media\AHF directory and the .zip file’s contents are extracted into the directory. We will install Oracle AHF into the D:\Oracle\AHF directory:


/* In an administrative Command Prompt */
D:\> cd Oracle

Create directories for installation of Oracle AHF
D:\Oracle> mkdir media\AHF AHF

D:\Oracle> cd media\AHF

AHF-Win_v20.1.1.zip transferred to the current directory
D:\Oracle\media\AHF> dir /b
AHF-Win_v20.1.1.zip

Extract contents of the .zip file to the current directory using 7-Zip or Windows Explorer
D:\Oracle\media\ahf> dir /b
AHF-Win_v20.1.1.zip

Please note, before attempting to install Oracle AHF on Windows we must amend the system PATH environment variable to include the location of the Perl executable perl.exe. This is usually found in the ‘perl\bin’ directory below the Oracle Home:

/* In an administrative Command Prompt */
D:\Oracle\media\ahf> cd extracted

D:\Oracle\media\ahf\extracted> dir /b
installahf.bat
oracle.ahf

Check if perl.exe is already on the PATH
D:\Oracle\media\ahf\extracted> perl -v
'perl' is not recognised as an internal or external command, operable program or batch file.

Search for per.exe
D:\Oracle\media\ahf\extracted> dir D:\perl.exe /s /b
D:\Oracle\product\11.2.0\db_1\perl\bin\perl.exe

Append the location of perl.exe to the system path variable
D:\oracle\media\ahf\extracted> SET PATH=%PATH%;D:\Oracle\product\11.2.0\db_1\perl\bin

Retry earlier 'perl -v' command
D:\Oracle\media\ahf\extracted> perl -v

This is perl, v5.10.0 built for MSWin32-x64-multi-thread

We now run installahf.bat with two parameters, -perlhome (the Perl home) and -ahf_loc, the location to which Oracle AHF is to be installed.

ORACLE TRACE FILE ANALYSER (TFA) ISSUES

Note that unlike installing Oracle AHF on Linux, as of the time of writing we cannot avoid installing the Oracle Trace File Analyser (TFA) component when installing Oracle AHF on Windows.

In testing, TFA has been seen to cause an issue whereby it continuously writes exception errors to a file within the Oracle AHF installation folder structure. Left unchecked, the file can grow to several GB in size, so it is necessary to disable Oracle TFA as soon as the installation of Oracle AHF completes.


/* In an administrative Command Prompt */
D:\Oracle\media\ahf\extracted> installahf.bat -perlhome D:\Oracle\product\11.2.0\db_1\perl ↵

You can disable Oracle TFA by performing the following steps:

1. Locate the ‘Oracle Trace File Analyser’ Windows service

2. Edit the service’s properties to stop and disable the service:

3. Stop TFA from the Command Line:

/* In an administrative Command Prompt */
D:\Oracle\media\ahf\extracted> cd \ D:\> cd Oracle\AHF\oracle.ahf\tfa\bin Stop TFA D:\Oracle\AHF\oracle.ahf\tfa\bin> tfactl.bat stop Stopping TFA from the Command Line Successfully stopped TFA Note that if the 'tfactl.bat stop' command fails with a 'missing api-ms-win-crt-runtime-l1-1-0.dll' error, download & install the Visual C++ Redistributable for Visual Studio 2015 and retry the command

Running ORAchk on Windows

Unlike running ORAchk on Linux, it is not possible for ORAchk to run on remote nodes in a Windows clustered database (Oracle RAC) environment. Therefore, when running ORAchk on Windows on Oracle RAC databases it is necessary to install Oracle AHF and run ORAchk on each cluster node separately.

Before running ORAchk on Windows you must ensure that a tnsnames.ora file exists in the network\admin directory below the Oracle Home and that all databases hosted on the server have an entry in the tnsnames.ora file.


/* In an administrative Command Prompt */
D:\> cd Oracle\AHF\oracle.ahf\bin
