ORA-01001 invalid cursor

Cause: Either a host language program call specified an invalid cursor or the value of the MAXOPENCURSORS option in the precompiler command were
too small. All cursors must be opened using the OOPEN call before being
referenced in any of the following calls: SQL, DESCRIBE, NAME, DEFINE,
BIND, EXEC, FETCH, and CLOSE. The Logon Data Area (LDA) must be
defined by using OLON or OLOGON. If the LDA is not defined, this message is issued for the following calls: OPEN, COM, CON, ROL, and LOGOFF.

Action: Check the erroneous call statement.
Specify a correct LDA area or open the cursor as required. If there is no problem with the cursor, it may be necessary to increase the MAXOPENCURSORS option value before precompiling
