openGauss典型应用场景配置

日志诊断场景

ODBC日志分为unixODBC驱动管理器日志和psqlODBC驱动端日志。前者可以用于追溯应用程序API的执行是否成功，后者是底层实现过程中的一些DFX日志，用来帮助定位问题。

unixODBC日志需要在odbcinst.ini文件中配置：

[ODBC]
Trace=Yes
TraceFile=/path/to/odbctrace.log

[GaussMPP]
Driver64=/usr/local/lib/psqlodbcw.so
setup=/usr/local/lib/psqlodbcw.so

psqlODBC日志只需要在odbc.ini加上：

[gaussdb]
Driver=GaussMPP
Servername=10.10.0.13（数据库Server IP）
...
Debug=1（打开驱动端debug日志）

 说明：  unixODBC日志将会生成在TraceFile配置的路径下，psqlODBC会在系统/tmp/下生成mylog_xxx.log。

高性能场景

进行大量数据插入时，建议如下：

• 需要设置批量绑定：odbc.ini配置文件中设置UseBatchProtocol=1、数据库设置support_batch_bind=on。
• ODBC程序绑定类型要和数据库中类型一致。
• 客户端字符集和数据库字符集一致。
• 事务改成手动提交。

odbc.ini配置文件：

[gaussdb]
Driver=GaussMPP
Servername=10.10.0.13（数据库Server IP）
...
UseBatchProtocol=1 （默认打开）
ConnSettings=set client_encoding=UTF8 （设置客户端字符编码，保证和server端一致）
