in listener.ora file..check SID_NAME

It should like this

(SID_DESC =
(GLOBAL_DBNAME = global_database_name)
(ORACLE_HOME = /oracle_home_path)
(SID_NAME = database_sid_name)
)


then reload listener "lsnrctl reload"

Increase the number of processes in your parameter file. (init.ora or spfile)

ALTER SYSTEM SET processes=250 SCOPE=SPFILE;
