TNS-01174: The sum of the POOL_SIZEs from each PRESPAWN_DESC is greater than the PRESPAWN_MAX

Cause: The minimum value for PRESPAWN_MAX should be the sum of the POOL_SIZEs.

Action: Be sure the parameters required for PRESPAWN_DESC are specified in each SID_DESC. For example: 

SID_LIST_LISTENER = (SID_LIST=(SID_DESC=(SID_NAME=sid)(PRESPAWN_ MAX=15)(ORACLE_HOME=oracle_home)(PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_ SIZE=10)(TIMEOUT=30))(PRESPAWN_DESC=(PROTOCOL=ipc)(POOL_ SIZE=5)(TIMEOUT=15)))) 

Add or correct these parameters in the LISTENER.ORA file.
