After adding 5 database connections to the Oracle probe, the "+" sign is no longer available in MCS. In MCS there are 5 databases, but in the Oracle probe GUI, there are more of them.
UIM 8.5 onwards
Engineering is confirming this is a limitation to 5 profiles of the Oracle probe in MCS. However, this can be resolved by updating the maxprofiles for Oracle template:
There are 2 types of templates for oracle mcs: Oracle and Oracle Enhanced. The latest version for Oracle is 2.22 and, for Oracle Enhanced is 5.33.
Therefore, you need to run the query according to the template you use in MCS:
Oracle: 'update ssrv2template set maxprofiles = <Profiles want to create> where probe like 'oracle%' and version = '2.22' '
Oracle Enhanced: 'update ssrv2template set maxprofiles = <Profiles want to create> where probe like 'oracle%' and version = '5.33' '
Please restart the Oracle probe. After you change the value in the database, you should be able to create more than 5 profiles.
