How can you check if your Oracle Client is 32 bit or 64 bit?
RESOLUTION 1:
If logged into Toad and connected to your database, go to Help | Support Bundle and review the section noted as "ORACLE CLIENT INFORMATION"
RESOLUTION 2:
If logged into SQL Plus, the banner will tell you 64-bit if the 64-bit version is installed. If it does not specify 64-bit then it is 32-bit (even though it does not explicitly say so).
RESOLUTION 3:
Bring up command line prompt. Cd into the client directory and type in/run TNSPING. This will display client information and should note 64bit or 32bit.
RESOLUTION 4:
If the two directories $ORACLE_HOME/lib32 and $ORACLE_HOME/lib are existing then it is 64 bit. If there is only an ORACLE_HOME/lib directory then it is 32 bit client.
*Note: In newer versions of the client, the library is not included and this directory may not exist.
RESOLUTION 6:
1. Open Registry by selecting Start | Run and entering REGEDIT
2. Go to Hkey_local_machine HKLM/Software
3. Check for an Oracle node. Verify the ORACLE_HOME variable.
-- If found this indicates that the client specified here is 64bit. Note the path ofthe ORACLE_HOME variable and the name.
4. Further check to see if there's a WOW6432Node node. If so, doe sthat have an Oracle node within it. Verify if there is also an ORACLE_HOME variable also. |
-- If found, this indicates that the client specified here is 32bit. Note the path ofthe ORACLE_HOME variable and the name.
When accessing the Oracle client, make sure you're accessing the correct client based of fthe Home name and the path.
