为使用ODBC连接trafodion软件，安装ODBC和配置

1. 确认是否安装unixODBC：

[trafodion@esgyn-01 testtxt]$ rpm -qa|grep unixODBC
unixODBC-2.2.14-14.el6.x86_64
[trafodion@esgyn-01 testtxt]$

2. 如果没有安装，可以执行：

yum install unixODBC.x86_64

3. 安装Trafodion ODBC驱动；驱动安装包在esgynDB_clients-2.2.1-RH6-x86_64.tar.gz；在安装过程中全部尽量选默认配置

[root@n09 chenqilin]# ls
esgynDB_clients-2.2.1-RH6-x86_64.tar.gz  esgyn-tpcds-kit  python
[root@n09 chenqilin]#
[root@n09 chenqilin]# tar xzf esgynDB_clients-2.2.1-RH6-x86_64.tar.gz
[root@n09 chenqilin]# ls
clients  esgynDB_clients-2.2.1-RH6-x86_64.tar.gz  esgyn-tpcds-kit  python
[root@n09 chenqilin]#
[root@n09 chenqilin]# cd clients/

Proceeding with install

ENTER a directory for library files
OR hit Enter to use the default [/usr/lib64] :

ENTER a directory for datasource template file
OR hit Enter to use the default [/etc/odbc] :

ENTER a directory for sample
OR hit Enter to use the default [/etc/odbc] :

TRAFODBC driver has successfully been installed.
  * Library libtrafodbc_l64_drvr.so is installed on /usr/lib64
  * data source template file TRAFDSN has been copied onto /etc/odbc
  * sample file has been copied onto /etc/odbc

[root@n09 PkgTmp]#

4. 添加 /etc/odbc.ini

[ODBC]
traceFlags = ERROR
TraceStart = 0
TraceFile = tracefile.log
MaxTraceFileSize = 1024
AppUnicodeType=utf16

[traf]
Description = traf instance in IDC vm 10.10.11.3
Driver = Trafodion
Catalog = TRAFODION
Schema = QA
DataLang = 0
FetchBufferSize = SYSTEM_DEFAULT
Server = TCP:10.10.11.252:23400
SQL_ATTR_CONNECTION_TIMEOUT = SYSTEM_DEFAULT
SQL_LOGIN_TIMEOUT = SYSTEM_DEFAULT
SQL_QUERY_TIMEOUT = NO_TIMEOUT
ServiceName = HP_DEFAULT_SERVICE

ClientCharSet = UTF8

注：配置了一个名为traf的ODBC连接，Server为需要连接的DCS Master，ClientCharSet = UTF8这个是为了避免用odb导入带中文字符入表后不是乱码。

5. 添加/etc/odbcinst.ini

[Trafodion]
Description = Trafodion ODBC Stand Alone Driver
Driver = /usr/lib64/libtrafodbc_drvr64.so
FileUsage = 1
UsageCount = 1
AppUnicodeType = utf16
Threading = 1

注：如果你驱动安装的位置不是默认的/usr/lib64，请修改Driver到你安装的驱动库位置

6. 在解压抱中执行./runconnect_test.sh脚本来查看是否配置正确：

[trafodion@esgyn-01 PkgTmp]$ ./runconnect_test.sh
In file included from sqlext.h:2071,
                 from connect_test.cpp:27:
sqlucode.h:20:20: error: sqlext.h: No such file or directory
Using Connect String: DSN=Default_DataSource;UID=ss;PWD=ss;

Connect Test Passed...
[trafodion@esgyn-01 PkgTmp]$
