    GTS (DBA)

      Hi all;

       

      Some links are include valid_for  option  some links do NOT include  valid_for attaribute ? - Why so ??

      What's the purpose of  valid_for=(all_logfiles, all_roles) ?

      What's the purpose of  valid_for=(online_logfiles,primary_role) ?

       

      Example parameters :

       

      log_archive_dest_1='location=/home/oracle/org/oradata/arch/'

      log_archive_dest_2='service=dummy'

       

      log_archive_dest_1='location=/home/oracle/org/oradata/arch/ valid_for=(all_logfiles, all_roles) db_unique_name=org'

      log_archive_dest_2='service=dummy lgwr async valid_for=(online_logfiles,primary_role) db_unique_name=dummy'


      Thanks in advance ..
