Does anyone know how Oracle's trace analyzer should be configured in RAC. It works fine in single instance but spits out the following message when I try to run it in a RAC instance. exec trca$i.trace_analyzer('racvt1n2_ora_7276.trc'); BEGIN trca$i.trace_analyzer('racvt1n2_ora_7276.trc'); END; * ERROR at line 1: ORA-00001: unique constraint (TRCANLZR.TRCA$_STAT_PK) violated ORA-06512: at "TRCANLZR.TRCA$D", line 642 ORA-06512: at "TRCANLZR.TRCA$D", line 1046 ORA-06512: at "TRCANLZR.TRCA$I", line 438 ORA-06512: at "TRCANLZR.TRCA$I", line 499 ORA-06512: at line 1 I have tried to completely de-install and then re-installed it but have not had any luck. and Any help will be appreciated.
