Navicat version: Navicat Premium 9.1.11 Oracle version: Oracle Database 10g Release 2 (10.2.0.1.0)
The following figure, failed to connect to the Oracle database using Navicat
Problem Reason:
Navicat OCI.dll does not support the GBK character set.
The following is a description of the Oracle official web site http://www.oracle.com/technetwork/topics/winsoft-085727.html
Version 10.2.0.5
Instant Client package-basic:all files required to run OCI, OCCI, and JDBC-OCI applications .2.0.5.zip (34,846,661 bytes)
*instant Client package-basic Lite:smaller version of the Basic, with only 中文版 error messages and Unicode, ASCII, an D Western European Character set support (10.2 only) Instantclient-basiclite-win32-10.2.0.5.zip (10,670,287 bytes)
Note that the Red section, the Lite version of OCI only supports Unicode, ASCII, and Latin character sets, this navicat hint does not support the GBK character set, so it can be inferred that NAVICAT does not support GBK is the OCI.dll version of the source,
Workaround:
Download a non-lite version of the OCI can download the address: http://www.oracle.com/technetwork/topics/winsoft-085727.html download Link: http:// Download.oracle.com/otn/nt/instantclient/10205/instantclient-basic-win32-10.2.0.5.zip
Unzip the downloaded Instantclient-basic-win32-10.2.0.5.zip to the Navicat installation directory and replace the original file
Then open the Navicat--> tool--> option--> other--> OCI, and in the OCI Library (oci.dll), select the Oci.dll in the folder you just unzipped.
