Last updated on FEBRUARY 08, 2017

Applies to:

Oracle Spatial - Version: and later   [Release: 10.2 and later ]
Information in this document applies to any platform.


  • Trying to create spatial index fails with:

    ORA-07445: exception encountered: core dump [mdrcrrdtbl()+1317] [SIGSEGV] [Invalid permissions for mapped object] [0x2AFE7D2D4008] [] []
  • Increasing SGA_TARGET as per <> does not solve the problem.

  • The table on which the index is created has more than 60 Million rows.
