本地TNSNAMES.ORA 配置如下
comm1=
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = A(PORT = 5524))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora10g)
)
)
oracle 服务器的地址是B
在A上做的是端口映射到B。
B服务器上监听进程是存在的,
但是通过本地PL/SQL连接时报 ora-12154 tns;监听进程不能解析在连接描述中符中给出的SERVICE_NAME

2)tnsping comm1能通吗?
3)是不是环境中有2个ORACLE_HOME 看下(注册表和环境变量)或者.bash_profile[oracle@localhost ~]$ oerr ora 12154
12154, 00000, "TNS:could not resolve the connect identifier specified"
// *Cause: A connection to a database or other service was requested using
// a connect identifier, and the connect identifier specified could not
// be resolved into a connect descriptor using one of the naming methods
// configured. For example, if the type of connect identifier used was a
// net service name then the net service name could not be found in a
// naming method repository, or the repository could not be
// located or reached.// *Action:
// - If you are using local naming (TNSNAMES.ORA file):
// - Make sure that "TNSNAMES" is listed as one of the values of the
// NAMES.DIRECTORY_PATH parameter in the Oracle Net profile
// (SQLNET.ORA)
// - Verify that a TNSNAMES.ORA file exists and is in the proper
// directory and is accessible.
// - Check that the net service name used as the connect identifier
// exists in the TNSNAMES.ORA file.
// - Make sure there are no syntax errors anywhere in the TNSNAMES.ORA
// file. Look for unmatched parentheses or stray characters. Errors
// in a TNSNAMES.ORA file may make it unusable.
// - If you are using directory naming:
// - Verify that "LDAP" is listed as one of the values of the
// NAMES.DIRETORY_PATH parameter in the Oracle Net profile
// (SQLNET.ORA).
// - Verify that the LDAP directory server is up and that it is
// accessible.
// - Verify that the net service name or database name used as the
// connect identifier is configured in the directory.
// - Verify that the default context being used is correct by
// specifying a fully qualified net service name or a full LDAP DN
// as the connect identifier
// - If you are using easy connect naming:
// - Verify that "EZCONNECT" is listed as one of the values of the
// NAMES.DIRETORY_PATH parameter in the Oracle Net profile
// (SQLNET.ORA).
// - Make sure the host, port and service name specified
// are correct.
// - Try enclosing the connect identifier in quote s.
//
// See the Oracle Net Services Administrators Guide or the Oracle
// operating system specific guide for more information on naming.
