I am a Java programmer and do not have in depth knowledge of database. I have gone through oracle documentation but I am not clear on what are the things other than FCF for which ONS is used.
I am asking this because I am putting a restriction in my code to set ONS config information only if FCF is enabled. Is that a valid check ? Will someone want to keep FCF disabled but still want to set ONS config, If yes then for what use case.
Thanks in advance.
You can gain some knowledge of the Oracle database by reading this fabulous manual from front to back:
Also, know your Oracle Editions and what each one is capable of doing.
ONS, FSF and TAF all seem to be related to RAC (You need RAC in order to do failovers)
XE does not support RAC and this is an XE forum.
(ie you have posted in the wrong forum.)
Please post in the correct forum.
