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


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

SQL> sho parameter service

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
service_names                        string      EBSTEMP

SQL> sho parameter service

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
service_names                        string      EBSTEMP, ebs_patch

After this Database connectivity issue should be resolved.
