Hi,
Sometimes you can get ” ORA-00472: PMON process terminated with error ” error.
Details of error are as follows.
shutdown immediate; database closed database dismounted RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of shutdown command at 05/16/2019 11:24:44 ORA-00472: PMON process terminated with error
To solve this problem, Use the following workaround.
alter system set "_in_memory_undo" = false scope=both sid='*';
