oracle 접속 에러

AS 2.1 에 oracle 9를 설치하였습니다.

원격으로 접속할 경우 접속이 되지 않는 상황이 발생하고 잇습니다.

현재 listen.ora와 tnsnames.ora 의 설정을 다음과 같습니다.

# LISTENER.ORA Network Configuration File: /opt/oracle/product/9.2.0/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
      )
      (ADDRESS_LIST 
        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.80)(PORT = 1521))
      )
    )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /opt/oracle/product/9.2.0)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = test.domain)
      (ORACLE_HOME = /opt/oracle/product/9.2.0)
      (SID_NAME = test)
    )
  )
)

# TNSNAMES.ORA Network Configuration File: /opt/oracle/product/9.2.0/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

TEST.LOCALDOMAIN =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.80)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test.domain)
    )
  )

다음과 같은 에러가 나오고 잇습니다. 리스너를 못찾고 있는 것입니다.

ORA-12545: Connect failed because target host or object does not exist

제가 아는 한도에서의 listen.ora와 tnsname.ora를 변경해 보았는데 안되고 잇습니다.

참고로 oracle 환경 변수는 다음과 같습니다.

 # Set the LD_ASSUME_KERNEL environment variable only for Red Hat 9 and
# for Red Hat Enterprise Linux Advanced Server 3 (RHEL AS 3) !!
# Use the "Linuxthreads with floating stacks" implementation instead of NPTL:
export LD_ASSUME_KERNEL=2.4.1

# Oracle Environment
export ORACLE_BASE=/opt/oracle
export ORACLE_HOME=/opt/oracle/product/9.2.0
export ORACLE_SID=test
export ORACLE_TERM=xterm
# export TNS_ADMIN= Set if sqlnet.ora, tnsnames.ora, etc. are not in $ORACLE_HOME/network/admin
export NLS_LANG=AMERICAN;
export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH

# Set shell search paths
export PATH=$PATH:$ORACLE_HOME/bin

아시는 분은 답글 부탁드리겠습니다.[/code]
