Explanation:
ORA-04031: unable to allocate string bytes of shared memory (“string”,”string”,”string”,”string”)
Cause: More shared memory is needed than was allocated in the shared pool or Streams pool.
Action: If the shared pool is out of memory, either use the DBMS_SHARED_POOL package to pin large
packages, reduce your use of shared memory, or increase the amount of available shared memory by
increasing the value of the initialization parameters SHARED_POOL_RESERVED_SIZE and
SHARED_POOL_SIZE. If the large pool is out of memory, increase the initialization parameter
LARGE_POOL_SIZE. If the error is issued from an Oracle Streams or XStream process, increase the
initialization parameter STREAMS_POOL_SIZE or increase the capture or apply parameter MAX_SGA_SIZE.
