ORA-32004: obsolete and/or deprecated parameter(s) specified
如果在某个高一些的版本Oracle中使用了不再支持的参数，那么可能在开启数据库的时候会报错 ：
SQL> startup

If you are using an spfile, values for this are given in v$spparamter, not v$parameter. You can confirm whatever initialization parameters are in effect at any given time by doing a 'show parameter parallel' to show what initialization parameter values are at that time for any parameter that has 'parallel' in it's name.
Anyway, to remedy the problem, even if parallel_server is not false, there is still an entry for it in the spfile, and that is why you are receiving the error. It is not serious, but to remove it you will have to recreate the spfile, or start using an init.ora text file instead. Use Step B from note 137483.1 to do this. You can create a pfile from the spfile, remove the parallel_server setting altogether from the pfile, then use the pfile to recreate the spfile.
