QUESTION
ANSWER
Answered 2021-Sep-30 at 11:42From the node-oracledb 5.0 changelog:
Webpack users should copy the node-oracledb binary into a sub-directory of the output directory. For example if the output directory is
dist
, then the binary should be indist/node_modules/oracledb/build/Release/oracledb-5.0.0-linux-x64.node
. A copy plugin inwebpack.config.js
can do this by copyingnode_modules/oracledb/build
to a directory of that same name. See Issue 1156.
A potential thing to review is the use of ES modules - I have not tried them in this context.
QUESTION
I am using a Node JS application that has Oracle Autonomous Database as a backend. It works perfectly on my local machine and I am able to connect it well without any issue. I tried deploying Node JS project to Azure WebAppService on Linux server.
Initially after deployment I my project was not able to find the Oracle client and so after searching a lot I was able to fix that problem by below
with this I was able to solve client issue. I have wallet files which I received from oracle which I have placed in admin folder
but now the problem is when I make any request I am getting this error

Answered 2021-Sep-16 at 10:21Thank you, Christopher Jones and saiharika213. Posting your suggestions as an answer to help other community members.
This ORA-28759: failure to open file
error seems you need to update the WALLET_LOCATION
directory in sqlnet.ora
. You can refer to Connecting to Oracle Cloud Autonomous Databases
You can resolve this error by changing the connection string to point to the wallet location.
Move the wallets to respective project folder and modify the connection string as below in dbConfig.js
.
Provide the wallet path from root till wallet folder.
For example:
QUESTION
I am trying to run simple SQL statements using Oracledb npm for Nodejs. This has worked in the past with no issue but suddenly I am getting this error in a different environment. Possibly due to aliases? I am not sure.
The goal of the line causing the issue is to close out the connection once it completes or fails. I found the logic directly in the docs from Oracle found here: http://oracle.github.io/node-oracledb/doc/api.html#connectionclose
Really would appreciate any help!
...ANSWER
Answered 2021-Apr-24 at 00:43If there is an error getting the connection, your catch block calls conn.close()
without having a valid conn
. This gives the error you see. It may not be the only cause, but tidying the code will help.
Your conn.close()
could be just once in a finally()
block. Look at examples like example.js e.g. like:
QUESTION
I logged in as user AN and created a procedure in sql developer:
...ANSWER
Answered 2021-Apr-01 at 22:42You are passing the string
execute ...
to the database. Butexecute
is not a SQL keyword - it is a SQL*Plus command. So the database doesn't understand it and gives an error. Instead dobegin viewSystemUsers() end;
.For ease of programming use async/await, not callbacks
Review the node-oracledb example impres.js becuase this shows the use of Implicit Results (which is what
dbms_sql.return_result()
is).Review the node-oracledb example plsqlproc.js.
You code could be like:

Also review the node-oracledb documentation.
To start with you need to use another bind variable to return the function result to. The trick is setting the type - I don't know what INFO_ITEM
is. Something like this might work:
