I have a database called NEWSDB running in a unix environment.
Under my $ORACLE_HOME/dbs, I have about 10 different init.ora files saved under different names. I am wondering which exact one is my database is using or if it's using all of them. Is it using all of them? The impression that I am having is that, any time a changed is made to the init.ora files, it's numbered in order to identify how many times changes where made to the init.ora file. I am trying to find out if the database uses all of init.ora files or not.

init.newsdb.ora001
init.newsdb.ora002
init.newsdb.ora003
init.newsdb.ora004
init.newsdb.ora005
init.newsdb.ora006
init.newsdb.ora007
init.newsdb.ora008
init.newsdb.ora009
