nls_date_format showing only DD-MON-RR

On a particular server , select sysdate from dual was showing only DD-MON-RR not full time stamp .

when i checked the nls_date_format , it was set as :-

nls_date_format                      string      DD-MON-RR HH.MI.SS AM

The issue was with parameter file in which the following parameters were set :-

*.fixed_date='2014-05-02'

and

*.nls_date_format='DD-MON-RR HH.MI.SS AM'

then , I commented the *.fixed_date='2014-05-02' and reset the nls_date_format and bounce the DB.

If any application which using XA transaction and connecting to oracle RAC database, is it required. This normal behavior and you do not have to worry about this error messages.  If you are sure that you are not using XA and want to stop these messages. You can disable the GTXn background processes, then you must set GLOBAL_TXN_PROCESSES to 0 in your parameter file. Setting this parameter to 0 will disable the XA support on an Oracle RAC database. GLOBAL_TXN_PROCESSES specifies the initial numb
