R12.2 Upgrade: Rapidwiz Prerequisite Check Fails With Message: DB Version Check Has Failed. Not able to check the Database version. Please make sure the Database is at 11.2.0.3 or higher

Solution:

To resolve the database connectivity issue, perform the following steps :

1. Review the sqlnet_ifile.ora or sqlnet.ora file and confirm the following entries are present:

  SQLNET.ALLOWED_LOGON_VERSION_SERVER

2. Update the sqlnet_ifile.ora or sqlnet.ora settings for the above parameters to the lowest version level 

that is required in your environment. 

For example:

a) If the initialization parameter SEC_CASE_SENSITIVE_LOGON is set to FALSE:

  SQLNET.ALLOWED_LOGON_VERSION_SERVER = 8

b) If SEC_CASE_SENSITIVE_LOGON is set to TRUE

  SQLNET.ALLOWED_LOGON_VERSION_SERVER = 10

After this Database connectivity issue should be resolved.

Modify the service_names parameter to include ebs_patch as shown below and retry.
