Summary<\/h1>\n
We have several points here. The 23ai version for ExaCC (and probably the same for OCI) is quite special since it forces us to use encryption because, in the end, it is Cloud. Usually (and 99% of the time) we don\u2019t need to call the dbca manually and we use the OCI tools which will call properly the parameters.<\/p>\n
Besides that, was quite a challenge (and nice at the end) to dig over the issue and identify the root cause. The documentation was quite new and obscure to discover where was the explanation about the correct parameters to be used. The idea for this post was to summarize the troubleshooting and resume all the information in one place.<\/p>\n
