我在同一个 VPC 中的 AWS 中托管了 2 个数据库实例:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
PL/SQL Release 12.1.0.2.0 - Production
"CORE 12.1.0.2.0 Production"
TNS for Linux: Version 12.1.0.2.0 - Production
NLSRTL Version 12.1.0.2.0 - Production
我正在使用 DBMS_FILE_TRANSFER 将转储文件从源数据库实例复制到目标数据库实例。
BEGIN
DBMS_FILE_TRANSFER.PUT_FILE(
source_directory_object => 'DATA_PUMP_DIR',
source_file_name => 'hotels.dmp',
destination_directory_object => 'DATA_PUMP_DIR',
destination_file_name => 'hotels_copied.dmp',
destination_database => 'to_rds'
);
END;
/
to_rds
我之前创建的数据库链接在哪里运行
create database link to_rds connect to OF_HOTEL identified by OFO
using '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hotelsdbtestaws.cwob1oxhu1so.eu-central-1.rds.amazonaws.com)(PORT=1521))(CONNECT_DATA=(SID=ORCL)))';
但是当我运行脚本时,我得到了这个错误:
Error report -
ORA-12170: TNS:Connect timeout occurred
ORA-06512: at "SYS.DBMS_FILE_TRANSFER", line 60
ORA-06512: at "SYS.DBMS_FILE_TRANSFER", line 168
ORA-06512: at line 2
12170. 00000 - "TNS:Connect timeout occurred"
*Cause: The server shut down because connection establishment or
communication with a client failed to complete within the allotted time
interval. This may be a result of network or system delays; or this may
indicate that a malicious client is trying to cause a Denial of Service
attack on the server.
*Action: If the error occurred because of a slow network or system,
reconfigure one or all of the parameters SQLNET.INBOUND_CONNECT_TIMEOUT,
SQLNET.SEND_TIMEOUT, SQLNET.RECV_TIMEOUT in sqlnet.ora to larger values.
If a malicious client is suspected, use the address in sqlnet.log to
identify the source and restrict access. Note that logged addresses may
not be reliable as they can be forged (e.g. in TCP/IP).
我试图设置超时:
SQLNET.INBOUND_CONNECT_TIMEOUT=600;
inbound_connect_timeout_listenername=600;
但我有一个错误:
Error starting at line : 12 in command -
SQLNET.INBOUND_CONNECT_TIMEOUT=600
Error report -
Unknown Command
Error starting at line : 13 in command -
inbound_connect_timeout_listenername=0
