Oracle Error Message
ORA-23603: string enqueue aborted due to low SGA
Reason for the Error
An attempt to enqueue a GoldenGate, XStream or Streams message was aborted because ORACLE is running low on memory allotted.
Solution
Either start consuming messages by enabling any GoldenGate, XStream or Streams propagation or apply which might be disabled. An alternative is to allot more memory to STREAMS, which can be done by increasing the streams_pool_size initialization parameter if one was defined or by increasing the shared_pool_size.
