ORACLE Connection Error

I’ve implemented all the directives, but the oracle gives the connection error.

[SIZE=14px]ORACLE 8.0.5 or Higher:[/SIZE]
ocilogon(): Error while trying to retrieve text for error ORA-01804

[SIZE=14px]Oracle PDO:[/SIZE]
Connection attempt failed: SQLSTATE[HY000]: pdo_oci_handle_factory: Error while trying to retrieve text for error ORA-01804 (/root/installer/php/php-7.0.14/ext/pdo_oci/oci_driver.c:640)

OS: Centos 7.5

In version 9.2.000 of ScriptCase, the oracle connection is working properly. It does not work properly in its current version.
