title: 603 -ORA-00603: ORACLE server session terminated by fatal error ORA-00600:
body: <p>I have an oracle DB which is in W28MSWIN1252  and using the Oracle DMU (Data Migration Assistant tool for Unicode) I'm trying to convert the encoding to to ALT32UTF8. I successfully passed the scanning, but the next step - the actual database conversion, stops on this operation(the table and column names are changes):</p>
  
  <pre><code>update  /*+ PARALLEL(A,4)*/ "MYSCHEMA"."MYTABLE1" A  set A."COL1" = SYS_OP_CSCONV(A."COL1", 'AL32UTF8'), A."COL2" = SYS_OP_CSCONV(A."COL2", 'AL32UTF8'), A."COL3" = SYS_OP_CSCONV(A."COL3", 'AL32UTF8'), A."COL4" = SYS_OP_CSCONV(A."COL4", 'AL32UTF8') WHERE A.ROWID IN (SELECT ROW_ID FROM SYSTEM.DUM$EXCEPTIONS WHERE OBJ# = 93203)
  </code></pre>
  
  <p>with this error:</p>
  
  <pre><code>603 - ORA-00603: ORACLE server session terminated by fatal error ORA-00600: Internal error code, arguments:[4882], [0x7FF7A52EEDB8],[0x7FF7A5A6D6B8], [0x7FF7C05ABB8],[],[],[]..
  </code></pre>
  
  <p>I Found an additional more info about the error in 
  C:\app\Oracle12\diag\rdbms...\trace\alert_ax12web.log:</p>
  
  <pre><code>    Refresh failed due to missing on - commit privilege for               "MYSCHEMA"."MYTABLE2"
      On commit
      MV "MYSCHEMA"."MYTABLE2" was not refreshed successfully.
      Number of MV refresh failures : 1.
      Errors in file C:\app\Oracle12\diag\rdbms\...\trace\ax12web_ora_6672.trc(incident = 12425) :

      ...
  </code></pre>
  
  <p>It seems that the real problem is : <strong>Refresh failed due to missing on - commit privilege for something</strong>. Unfortunately granting all privileges to everyone on this table via:</p>
  
  <pre><code>   grant ALL on "MYSCHEMA"."MYTABLE1" to public;
  </code></pre>
  
  <p>doesn't help. I still get this error.</p>
  
  <p>P.S. I don't have additional support from oracle :(. </p>
  
  <p>Any Ideas? </p>
  
  <p>Thanks in advance,</p>
