2. No Execute Privileges: MDS database user created by Repository Creation Utility (RCU) does not have  EXECUTE privilege on DBMS_OUTPUT, DBMS_STATS, and DBMS_LOB. Log into the Oracle Database as SYSDBA and GRANT  EXECUTE Privileges to the MDS User. 

ERROR – RCU-6080 Global prerequisite check failed for the specified database

Cause for the Error – ” The selected Oracle database is a multitenant container database (CDB). Connecting to a multitenant container database (CDB) is not supported. Connect to a valid pluggble database (PDB)”  

Before we execute the Repository Creation Utility, the following validations need to be performed

1.  Do not Select Container Database: While installing the Oracle Database ensure that the Container Database Checkbox is not selected. 

2. Pluggable Database must be installed: The Oracle Database installs the Pluggable Database (PDB) which is to be used while installing RCU.  The below screen shows the XEPDB1 PDB created by the Oracle Database Installer.  Save this information as it is to be provided when providing Database details for loading SOA Schema

3. Oracle Database Validations:  Before we proceed with the RCU Setup, the below given SQLs can be useful to validate the installed Oracle Database. 

Validate if the Database is created as CDB or not

SELECT CDB FROM V$DATABASE; 

CDB
----
YES

Retrieve the installed Pluggable Database . In our case , the PDB XEPDB1 exists. 

SELECT CON_ID, NAME, OPEN_MODE FROM V$PDBS;

CON_ID          NAME            OPEN_MODE
2             PDB$SEED          READ ONLY 
3             XEPDB1            READ WRITE 

Retrieve the Service Name for the Pluggable Database  XEPDB1

select name from v$services;

name 
---
SYS$BACKGROUND
SYS$USERS
xepdb1

 

Provide the Oracle Database Connection details in RCU Database Connection Screen with Service Name as XEPDB1
