해결 방법:
Oracle listener. ora 파일 열기:
（oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora）
수정 전:
# listener.ora Network Configuration File: /app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER =  (SID_LIST =    (SID_DESC =      (SID_NAME = PLSExtProc)      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)      (PROGRAM = extproc)    )  )LISTENER =  (DESCRIPTION_LIST =    (DESCRIPTION =      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))      (ADDRESS = (PROTOCOL = TCP)(HOST = suse10.site)(PORT = 1521))    )  )

수정 후:

# listener.ora Network Configuration File: /app/oracle/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /app/oracle/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = suse10.site)(PORT = 1521))
    )
  )

위의 빨간색 문 자 는 추 가 된 내용 입 니 다. (ORCL - SID 데이터베이스 이름) Oracle 모니터 를 다시 시작 합 니 다. 문제 해결.
