How To Upgrade Oracle Client 11g To 12c In Windows

Concerned about risks and desire to lock downwards your Oracle client for end user Windows PCs?

Take a need for the 'cantankerous connectedness query' feature of Toad Information Signal? The solution is within your grasp!

Let's go straight to it. Yous need an Oracle client to access an Oracle database from Toad Information Bespeak. Let me share my step by step teaching in an easy-peasy-lemon-squeezy fashion!

Note i:  Oracle client is needed to access multiple data sources from Toad Information Signal referred to every bit a 'cross connection query'.

Note two:  This example volition particular an Oracle 12c 64 bit install on Windows ten for an Oracle 12c example with a PDB.

Note 3:  The Oracle 11g client install is most exactly the same every bit the Oracle 12c customer install.

here are 5 steps to this process which include:

i)      Choice your Oracle customer

2)      Install the Oracle client

3)      Disable sqlplus

four)      Review registry entries

five)      Configure Toad Information Point Oracle Connectedness

Recommendation is to review all steps before proceeding.  In item, Stride 4 Review registry entries consisting of earlier and later on screen shots.  Trust me, you will feel improve, empowered, and more than confident in the terminate!

Step i – Pick your Oracle client

Your options within the telescopic of this article are an Oracle 11g or Oracle 12c client for 32 or 64 flake compages. Consult the Oracle website for other customer versions as needed.

Oracle 12c client (32 and 64 chip) can be found here:

http://www.oracle.com/technetwork/database/enterprise-edition/downloads/database12c-win64-download-2297732.html

Oracle 11g 32 flake customer can be constitute here:

http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win32soft-098987.html

Oracle 11g 64 bit client can exist institute here:

http://www.oracle.com/technetwork/database/enterprise-edition/downloads/112010-win64soft-094461.html

Pay Attention Notation ane:  Be careful which Oracle client yous choose. If the intent is to utilise the Oracle client for other uses likewise Toad Data Point, Exist FOREWARNED some legacy systems will just work with a 32 bit Oracle client. Please understand your environs before choosing an Oracle client.

Toad Data Indicate volition work seamlessly with either the 32 or 64 bit Oracle 11g or Oracle 12 client.

Step 2 – Install the Oracle client

Locate the downloaded Oracle 12c 64 bit client zip file.

Right click on file and extract into a directory.

Enter a directory to excerpt files.

Click Extract. Notation:  This could take a few minutes.

Working…

Oracle 12c 64 flake client has now been extracted

Double click 'setup.exe'.

This may examination your patience, let information technology piece of work! (Sometimes a infinitesimal or less tin can seem similar an eternity).

Don't touch anything!

Pay Attending Note 2: Disquisitional decision fourth dimension at present! The default is the 'Instant Client' which will allow for Oracle connections to one Oracle database at a time. If your users need the Toad Information Point 'cross connection query' feature (virtually volition) DO NOT install the 'Instant client'.

Pay Attention Note iii: Choosing the 'Runtime' option will eliminate whatsoever Oracle client Administrator tools enabling LOCKDOWN and saving 0.4 GB of local end user Windows PC deejay space. Toad Data Indicate 'cross connection query' feature will all the same work. Stay with me and go on to follow the instructions.

Choose the 'Runtime' pick.

Click Next.

Choose language.

Click Next.

Accept the defaults – my preference.

Or change to reverberate your own environment.

Click Side by side.

Working…

Relax, the Prerequisite Check should complete successfully momentarily. If non, bank check the log files and correct equally directed.

Accept the default Windows Built-in Business relationship – my preference.

Click Side by side.

Verify Global Settings. No changes should exist required at this point.

My preference is to not save the response file.

Option:  Click 'Save Response File'. A screen will announced to enter a filename to tape the install responses.  Utilize this option if you are having issues installing the Oracle Client. Response file log entries will help in debugging any issues that may occur. Rarely accept I seen any bug during this function of the Oracle 11g/12c customer install.

Click Install.

Be patient, the process is working.

Pay Attention Note 4: The default is 'Public networks, such equally those in airports and java shops …'.  Depending on your local Coffee implementation, you may or may non get this message. If you lot do, it is HIGHLY RECOMMENDED to Modify the default to 'Private networks, such as my home or piece of work network'.

Click Permit Access.

Success!!  Party time!

You lot have now just installed the Oracle 12c 64 scrap client!

Click Close!

Step three – Disable sqlplus

The sqlplus.exe installed with the Oracle client opens the door for access to Oracle databases.

To reduce risk exposure delete or rename the sqlplus.exe file in the directory where the Oracle 12c client was installed.

This is the final LOCKDOWN pace in this article.

Allow'due south review.

1. The Oracle 12c client has been installed with the 'Runtime' option thus eliminating any Ambassador tools.
2. The sqlplus.exe file has been deleted or renamed from the client estimator.
3. The Oracle 12 customer has now been installed lightweight and securely but still providing all the functionality required for connecting to Oracle databases.
4. Toad Data Indicate users tin can at present utilize the 'cross connectedness query' feature when connected to an Oracle database.

You have past the half way bespeak, only ii steps get!!!

Pace 4 – Review registry entries

Beginning the Windows registry editor.

Purpose of reviewing registry entries is to sympathize the heart of where the Oracle client is setup for Windows.  It is highly recommended not to alter any registry entry values for the Oracle customer.

                          Earlier                        Oracle Client Install
            HKEY_LOCAL_MACHINE                        -->                          SOFTWARE -->                          ODBC                      

                          BEFORE                        Oracle Client Install
            HKEY_LOCAL_MACHINE -->             SOFTWARE -->            Oracle                      

This PC has an Oracle database case running.  This would be highly unusual for an stop user. The KEY_OraDB12Home1 is the Oracle database dwelling.

                          AFTER                                      Oracle Client Install            
HKEY_LOCAL_MACHINE -->SOFTWARE -->            ODBC          

                          Subsequently                        Oracle Client Install
            HKEY_LOCAL_MACHINE -->             SOFTWARE                        -->                                          Oracle                      

Step v – Configure Toad Data Point Oracle Connection

Afterward installing the Oracle customer, setting upwards a TNS entry is recommended. Information technology's like shooting fish in a barrel – let me show y'all!

Ooooh, the magic TNS_ADMIN environment variable.  Many people forget this step which can cause chaos and mayhem.

First, create the tnsnames.ora file which can be placed anywhere on a client Windows PC.

My preference is to place the file in the Oracle 12c client directory structure as shown below.

Create a file called tnsnames.ora with your specific database connection data similar to the examples below. In that location are many different and right ways to specify a tnsnames.ora entry. Consult with your Oracle DBA for TNS entry information specific to your Oracle environs.

Oracle 12c with CDB/PDB configuration

PDB2 =
  (Clarification=
    (Accost = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA=
      (SERVER = dedicated)
      (SERVICE_NAME = pdborcl)
    )
  )

Annotation:  The CDB/PDB tnsnames entry will require an entry into the listener.ora file similar to this:

    (SID_DESC =
      (GLOBAL_DBNAME = pdborcl)
      (SID_NAME = pdborcl)
    )

Oracle 11g or Oracle 12c (No CDB/PDB) standalone database

DEV.ABC.NETWORK=
  (DESCRIPTION=
    (Accost=
      (PROTOCOL=TCP)
      (HOST=server01.abc.network)
      (PORT=1521)
    )
    (CONNECT_DATA=
      (SERVER=dedicated)
      (SID=dev)
    )
  )

Case of a tnsnames.ora file and location

C:Usersgrego>cd C:appclientgregoproduct.1.0client_1networkadmin              
 C:appclientgregoproduct.1.0client_1networkadmin>
C:appclientgregoproduct.i.0client_1networkadmin>blazon tnsnames.ora                
PDB2 =
  (Clarification=
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA=
      (SERVER = dedicated)
      (SERVICE_NAME = pdborcl)
    )
  )
C:appclientgregoproduct.1.0client_1networkadmin>
            

Now let'southward go create the TNS_ADMIN environment variable!!

Click 'Advanced organization settings'.

Click 'Surround Variables'.

In this example, the TNS_ADMIN surround variable does not exist in the list to a higher place. We need to create a TNS_ADMIN variable and point information technology to the tnsnames.ora file created earlier.

If the TNS_ADMIN environs variable already exists the PC has already been configured. Consult with a DBA before modifying to ensure other applications will not be affected.

My preference is to put this variable at the system level in the event another user account on this Windows PC requires admission to Toad Data Indicate via the Oracle client.

Click 'New' in the 'Organisation variables' box equally shown above by carmine pointer.

Enter the Variable Name as TNS_ADMIN.

Enter the path to the tnsnames.ora file as

              C:appclientgregoproduct.one.0client_1networkadmintnsnames.ora.

Click OK.

Awesome!  TNS_ADMIN variable has been created!

Click OK and exit all the way out of 'Avant-garde system settings'

At present all the effort will pay off!

Launch Toad Data Betoken and we will now create a Toad Data Point Oracle connection!!!

There are several ways to fix up an Oracle connexion. This is ane of the most straight forward methods.

1-Click on the 'Connectedness' menu icon. A screen with many connectedness types volition appear.

ii-Choose 'Oracle' equally indicated higher up.

From the dropdown list choose the entry of the database you lot want to connect to.

Choosing PDB2 in this instance.

Enter User, for example hr.

Enter Password.

Click 'Save Password' box – my preference for simplicity but could exist a security risk.

Click the Avant-garde tab – my preference merely optional.

In that location is no requirement to specify a 'Category' of the connection. Information technology is perfectly fine to 'Click Connect' from either the 'Avant-garde' or 'Login' tab.

Click on the 'Category' dropdown and choose appropriate environment.  'Evolution' – my preference.

Optionally – Click 'Connect on Startup', my preference is Not to bank check this box. Unnecessary open connections consume valuable resource.

Click 'Connect'.

You did it!!!

Congratulations on completing an Oracle 12c client install and setting up a Toad Information Bespeak Oracle connection!

All done. Q.Due east.D.

Celebration time now!!!
