V$SQL_SHARED_CURSOR explains why a particular child cursor is not shared with existing child cursors. Each column identifies a specific reason why the cursor cannot be shared.

Column Datatype Description
SQL_ID VARCHAR2(13) SQL identifier
ADDRESS RAW(4 | 8) Address of the parent cursor
CHILD_ADDRESS RAW(4 | 8) Address of the child cursor
CHILD_NUMBER NUMBER Child number
UNBOUND_CURSOR VARCHAR2(1) (Y|N) The existing child cursor was not fully built (in other words, it was not optimized)
SQL_TYPE_MISMATCH VARCHAR2(1) (Y|N) The SQL type does not match the existing child cursor
OPTIMIZER_MISMATCH VARCHAR2(1) (Y|N) The optimizer environment does not match the existing child cursor
OUTLINE_MISMATCH VARCHAR2(1) (Y|N) The outlines do not match the existing child cursor
STATS_ROW_MISMATCH VARCHAR2(1) (Y|N) The existing statistics do not match the existing child cursor
LITERAL_MISMATCH VARCHAR2(1) (Y|N) Non-data literal values do not match the existing child cursor
FORCE_HARD_PARSE VARCHAR2(1) (Y|N) ???
EXPLAIN_PLAN_CURSOR VARCHAR2(1) (Y|N) The child cursor is an explain plan cursor and should not be shared
BUFFERED_DML_MISMATCH VARCHAR2(1) (Y|N) Buffered DML does not match the existing child cursor
PDML_ENV_MISMATCH VARCHAR2(1) (Y|N) PDML environment does not match the existing child cursor
INST_DRTLD_MISMATCH VARCHAR2(1) (Y|N) Insert direct load does not match the existing child cursor
SLAVE_QC_MISMATCH VARCHAR2(1) (Y|N) The existing child cursor is a slave cursor and the new one was issued by the coordinator (or, the existing child cursor was issued by the coordinator and the new one is a slave cursor)
TYPECHECK_MISMATCH VARCHAR2(1) (Y|N) The existing child cursor is not fully optimized
AUTH_CHECK_MISMATCH VARCHAR2(1) (Y|N) Authorization/translation check failed for the existing child cursor
BIND_MISMATCH VARCHAR2(1) (Y|N) The bind metadata does not match the existing child cursor
DESCRIBE_MISMATCH VARCHAR2(1) (Y|N) The typecheck heap is not present during the describe for the child cursor
LANGUAGE_MISMATCH VARCHAR2(1) (Y|N) The language handle does not match the existing child cursor
TRANSLATION_MISMATCH VARCHAR2(1) (Y|N) The base objects of the existing child cursor do not match
BIND_EQUIV_FAILURE VARCHAR2(1) (Y|N) ???
INSUFF_PRIVS VARCHAR2(1) (Y|N) Insufficient privileges on objects referenced by the existing child cursor
INSUFF_PRIVS_REM VARCHAR2(1) (Y|N) Insufficient privileges on remote objects referenced by the existing child cursor
REMOTE_TRANS_MISMATCH VARCHAR2(1) (Y|N) The remote base objects of the existing child cursor do not match
LOGMINER_SESSION_MISMATCH VARCHAR2(1) (Y|N) LogMiner Session parameters mismatch
INCOMP_LTRL_MISMATCH VARCHAR2(1) (Y|N) Cursor might have some binds (literals) which may be unsafe/non-data. Value mismatch.
OVERLAP_TIME_MISMATCH VARCHAR2(1) (Y|N) Mismatch caused by setting session parameter ERROR_ON_OVERLAP_TIME
EDITION_MISMATCH VARCHAR2(1) (Y|N) Cursor edition mismatch
MV_QUERY_GEN_MISMATCH VARCHAR2(1) (Y|N) Internal, used to force a hard-parse when analyzing materialized view queries
USER_BIND_PEEK_MISMATCH VARCHAR2(1) (Y|N) Cursor is not shared because value of one or more user binds is different and this has a potential to change the execution plan
TYPCHK_DEP_MISMATCH VARCHAR2(1) (Y|N) Cursor has typecheck dependencies
NO_TRIGGER_MISMATCH VARCHAR2(1) (Y|N) Cursor and child have no trigger mismatch
FLASHBACK_CURSOR VARCHAR2(1) (Y|N) Cursor non-shareability due to flashback
ANYDATA_TRANSFORMATION VARCHAR2(1) (Y|N) Is criteria for opaque type transformation and does not match
INCOMPLETE_CURSOR VARCHAR2(1) (Y|N) Cursor is incomplete: typecheck heap came from call memory
TOP_LEVEL_RPI_CURSOR VARCHAR2(1) (Y|N) Is top level RPI cursor
DIFFERENT_LONG_LENGTH VARCHAR2(1) (Y|N) Value of LONG does not match
LOGICAL_STANDBY_APPLY VARCHAR2(1) (Y|N) Logical standby apply context does not match

BIND_UACS_DIFF VARCHAR2(1) (Y|N) One cursor has bind UACs and one does not
PLSQL_CMP_SWITCHS_DIFF VARCHAR2(1) (Y|N) PL/SQL anonymous block compiled with different PL/SQL compiler switches

CROSSEDITION_TRIGGER_MISMATCH VARCHAR2(1) (Y|N) The set of crossedition triggers to execute might differ
PQ_SLAVE_MISMATCH VARCHAR2(1) (Y|N)Top-level slave decides not to share cursor
TOP_LEVEL_DDL_MISMATCH VARCHAR2(1) (Y|N)Is top-level DDL cursor
MULTI_PX_MISMATCH VARCHAR2(1) (Y|N)Cursor has multiple parallelizers and is slave-compiled
BIND_PEEKED_PQ_MISMATCH VARCHAR2(1) (Y|N) Cursor based around bind peeked values
MV_REWRITE_MISMATCH VARCHAR2(1) (Y|N)Cursor needs recompilation because an SCN was used during compile time due to being rewritten by materialized view
ROLL_INVALID_MISMATCH VARCHAR2(1) (Y|N)Marked for rolling invalidation and invalidation window exceeded
OPTIMIZER_MODE_MISMATCH VARCHAR2(1) (Y|N)Parameter OPTIMIZER_MODE mismatch (for example, all_rows versus first_rows_1)
PX_MISMATCH VARCHAR2(1) (Y|N)Mismatch in one parameter affecting the parallelization of a SQL statement. For example, one cursor was compiled with parallel DML enabled while the other was not.
