Cause: PRESPAWN_DESC in each SID_DESC
does not have required fields.
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=5)(ORACLE_HOME=<oracle_home>)(PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=10)(TIMEOUT=30))))
Add or correct these parameters in the LISTENER.ORA file
