I'm trying to use node-oracle to connect to a Oracle 11g database in UNIX. I can connect fine to the database using TOAD, but now I want to do application queries and this is what I did:
我正在尝试使用node-oracle连接到UNIX中的Oracle 11g数据库。我可以使用TOAD很好地连接到数据库,但是现在我想要进行应用程序查询,这就是我所做的:
NodeJS code:
NodeJS代码:
var oracle = require('oracle');
var connectData = {
hostname: "host.com",
port: 1521,
database: "DB0000",
user: "me",
password: "password"
}
oracle.connect(connectData, function(err, connection) {
if (err) { console.log("Error connecting to db:", err); return; }
connection.execute("SELECT systimestamp FROM dual", [], function(err, results) {
if (err) { console.log("Error executing query:", err); return; }
console.log(results);
connection.close();
});
});
Then I this command on the unix box:
然后我在unix上输入这个命令:
sh-3.2$ OCI_LIB_DIR= /oracle/client/v11.2.0.2-64bit/client_1/lib/ OCI_INCLUDE_DIR=/client/v11.2.0.2-64bit/client_1/rdbms/public/ OCI_HOME=/oracle/clien
t/v11.2.0.2-64bit/client_1/ NLS_LANG=.UTF8 LD_LIBRARY_PATH=/client/v11.2.0.2-64bit/client_1/lib/ /bin/node app.js
I get the following error:
我得到以下错误:
terminate called after throwing an instance of 'oracle::occi::SQLException'
what(): Error while trying to retrieve text for error ORA-01804
Some notes:
一些注意事项:
- I haven't set up env variables properly yet, this was my first test, thus the long
node
command. - 我还没有正确地设置env变量,这是我的第一个测试,因此是long node命令。
- the paths are similar to those described but I removed the prefixes which would tie this to my company
- 这些路径与所描述的路径相似,但我去掉了与公司相关的前缀
I've looked around the web and a lot of people point this to a poorly configured LD_LIBRARY_PATH
variable. If I ls
that folder I get:
我浏览了一下web,很多人将它指向一个配置不良的LD_LIBRARY_PATH变量。如果我打开文件夹,我得到:

I've looked at these question, but although similar I couldn't troubleshoot my problem with them:
我研究过这些问题,但尽管类似,我也无法解决我的问题:
- Error while trying to retrieve text for error ORA-01019
- 尝试检索错误ORA-01019的文本时出错
- Error while trying to retrieve text for error ORA-01804
- 试图检索错误的文本时出错,ORA-01804。
Cheers.

Thanks to @evenro, I went back to look at Error while trying to retrieve text for error ORA-01804 and tried setting the ORACLE_HOME
environment variable.
感谢@evenro,我在试图检索Error ORA-01804文本时查看了Error,并尝试设置ORACLE_HOME环境变量。
It worked, but then I started checking which variables I really needed, so in the end I only used:
它起作用了,但后来我开始检查哪些变量是我真正需要的,所以最后我只使用了:
- ORACLE_HOME: pointing at the oracle client basedir
- ORACLE_HOME:指向oracle客户端basedir
- LD_LIBRARY_PATH: point at the lib folder inside the client
- LD_LIBRARY_PATH:指向客户端的lib文件夹。
This is how it worked in the end:
这就是它最终的工作原理:
ORACLE_HOME=/somefolder/oracle/client/v11.2.0.2-64bit/client_1/ LD_LIBRARY_PATH=/somefolder/oracle/client/v11.2.0.2-64bit/client_1/lib/ node app.js
Thank you again for all the help in the comments, much appreciated.
再次感谢您在评论中的帮助,非常感谢。

In my case I solved it like this for python
在我的例子中,我是这样为python解的
I solved this by simply zipping the files properly with the symbolic links
我通过使用符号链接正确地压缩文件来解决这个问题
First I created three symbolic links :
首先,我创建了三个符号链接:
ln -s ./lib/libaio.so.1.0.1 ./lib/libaio.so.1
ln - s。/ lib / libaio.so.1.0.1。/ lib / libaio.so.1
ln -s ./lib/libaio.so.1.0.1 ./lib/libaio.so
ln - s。/ lib / libaio.so.1.0.1。/ lib / libaio.so
ln -s ./lib/libaio.so.1.0.1 ./libaio.so.1.0.1
ln - s。/ lib / libaio.so.1.0.1。/ libaio.so.1.0.1
ln -s ./lib/libclntsh.so.12.1 ./lib/libclntsh.so
ln - s。/ lib / libclntsh.so.12.1。/ lib / libclntsh.so
then I was zipping it incorrectly I did it like this:
然后我把拉链拉错了,我是这样做的:
zip --symlinks -r9 ~/lamda.zip *
zip——符号链接r9机型~ /λ。邮政编码*
It worked! properly then.Hope it helps somebody.
它工作!正确。希望它能帮助别人。
