What can you do to reduce the chance of this error in the future?
Exhibit:

A.
Increase the value of SGA_MAX_SIZE

B.
Enable automatic memory management

C.
Set the PRE_PAGE_SGA parameter to true

D.
Lock the System Global Area (SGA) in memory

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.

In the explanation it says that you can increase MAX_SGA_SIZE, or rather SGA_MAX_SIZE.
However enablaling automatic memory management could result in memory being taken from the PGA which could possibly solve the issue.
