ORA-00018: maximum number of sessions exceeded 解决办法

ORA-00018: maximum number of sessions exceeded 解决方法

原因：processes和sessions太小

解决方法：调大processes和sessions，一般sessions=processes * 1.1 +5

 SQL> alter system set processes=300 scope=spfile;

         SQL> alter system set sessions=335 scope=spfile;

         SQL> shutdown immediate;

         SQL> startup;
