Re: OMF or not OMF? DBCA or Manual scripts

Please note that the comments in favor of DBCA did not extol the virtues of the GUI nature of the tool in any way, but rather advocated two different scripting capabilities for automation. I haven't seen anyone praise GUI interfaces for repetitive tasks.

Speaking for myself, I use DBCA "-silent" or at least the generated scripts for automation of the other tasks in creating a database (besides the CREATE DATABASE command) such as "orapwd" or "oradim", as appropriate to the OS, because I see no reason to re-learn the hard way what Oracle has already developed for new releases. I don't always agree with what has been developed, but that is what editors are for. Also, as you noted, junior DBAs are less likely to encounter problems with a scripted solution, while learning the most from studying the scripts themselves.

ASM has a lot of advantages over file-systems, certainly more advantages than disadvantages. OMF has a lot of advantages over obsessing about file naming. And DBCA (as well as the OUI) support scripting for automation, which beats trying to maintain one's own library of "crdb_<db-version>.sh" scripts, as I've done for so long.

Old dogs can learn new tricks, but only if they realize the old tricks don't necessarily improve with age.

Thanks!
