CURSOR_SHARING

CURSOR_SHARING determines what kind of SQL statements can share the same cursors.

Values:

• FORCE

  Allows the creation of a new cursor if sharing an existing cursor, or if the cursor plan is not optimal.

• SIMILAR

  Causes statements that may differ in some literals, but are otherwise identical, to share a cursor, unless the literals affect either the meaning of the statement or the degree to which the plan is optimized.

• EXACT

  Only allows statements with identical text to share the same cursor.

  Note:

  Forcing cursor sharing among similar (but not identical) statements can have unexpected results in some DSS applications, or applications that use stored outlines.
