스프링 프레임워크 + tomcat 8.0 + oracle 11g 에서 혼자 로컬로 DB를 사용할 때는 아무 문제가

없다가 여러 인원이 DB서버 하나를 사용하게 될 때 발생했던 오류

close()를 해줘야 하는데 안하는게 쌓이다 보니 결국 오류가 뿜음..


ORA-12519, Error preloading the connection pool, no appropriate service handler found 보인다.



경고: Unexpected exception resolving reference

오류 해결방법

1. close()를 해준다.


2. SELECT * FROM V$SESSION WHERE OSUSER != 'SYSTEM';  으로 점유하는 것을

확인하여 이상이 있는지 체크





이 글에서 소개할 방법은 3번

3. processes의 할당량을 늘려준다.


select * from v$resource_limit where resource_name = 'processes';

위 내용을 입력하여 현재 사용중인 수가 할당보다 많으면 위 오류를 나온다.


현재 32 최대 36 할당 100 




먼저, cmd를 실행한다.

sqlplus /nolog

SQL> conn /as sysdba


SQL>alter system set processes=200 scope=spfile;

               값은 적당하게~


SQL> shutdown immediate;

SQL> startup;




재시작까지 완료되고 다시 확인을 하면




위처럼 allocation, limit 값이 늘어난 걸 확인할 수 있다.
