I am testing this plugin with local DB2 instance, there are lot of errors in console and I see no tables in table view.

How did you configure connection to DB2?

I use following settings:

I use the database URL in the DB2 connection for a database directly, and all data is retrieved successfully, and the UI shows correct

Could you please share your database URL, of course without sensitive data?

We have no experience with DB2 (I and nobody of my colleagues), so we are struggling with this a bit

Ideally, also a screenshot of connection settings with erased sensitive data

Thank yout

Please check this screenshot for the connection string

this after add new rows

Great thanks, I am connected now!

Sometimes it shows correct structure, sometimes not...

Probably problem is in method incrementalAnalysis in Analyser ? If this method will be deleted, it will behave better

We have to do more test, but basically it seems to work

As your plugin has GPL license, I have to ask you, whether it is OK for you to be shipped with commercial DbGate Premium?
Of course, it will be also part of opensource Community

We have lot of tests for each DB engine (approx. 100), I could merge DB2 plugin into DbGate, but with - "Experimental" status, until all these tests will be implmeneted - passed or marked as skip

Thank you

Also, when you choose "All schemas", the are 8 of procedures without name

This must be returned from Analyser class

Thanks for the update! I'll investigate the incremental incrementalAnalysis of the issue and the bug where eight procedures lack names under "All schemas." I'm happy to help with testing to stabilize the plugin.

I'm fine with the GPL-licensed plugin being included in both DbGate Community and Premium editions. Please let me know if any licensing details need discussion.

Labeling the plugin "experimental" until tests are complete makes sense. I can assist with test implementation or debugging. Let me know the next steps!

Hi Jan,

I've addressed the issue in a new pull request (#1135).
Could you please review it when you have a moment?
If everything looks good, I'd recommend merging this new PR instead of the previous one.

Hi @janproch
i hope you are doing well!
Did you check it?

Hi @GergesBernaba1 ,

yes I did, thank you
I am now a bit stucked with new release, which is planned to June 16, but I want to merge your new PR into this release, so that DB2 support will be part of this (also with upcoming Firebird support)
I believe that we will have capacity to merge and test this next week

Thank you

I’d be glad to contribute more to this project. Do you have a task list I can help with? Feel free to assign me any items.

Thanks for the offer. There is lot of unsolved issue for DbGate - https://github.com/dbgate/dbgate/issues

If you choose something, better to let me know, some issues are already in progress

Thanks

BTW. I have merged your newer DB2 PR into new feature branch - feature/db2, I will run some tests in this branch and then merge it into master - PR https://github.com/dbgate/dbgate/issues

No good news, we have three times red https://github.com/dbgate/dbgate/actions/runs/15536757630 ...
I tried to update electron (https://www.npmjs.com/package/ibm_db claims that it supports electron 32-35), but yet without success

@janproch, Are you trying to update the Electron version to: 32.1.0!

Could run the action again!

I tried change version - 32.1.0, the same error - https://github.com/dbgate/dbgate/actions/runs/15577442183/job/43864975613

Build process is building native img_db package, but it should use precompiled version, probably precompiled version is not found

Probably right electron version with precompiled packages should solve this. But unfortunately, I have no capacity to solve this before current release, so probably we have to postpone adding DB2 to next release

It works fine, check the screenshot.

Hi @janproch
Are you trying it again? In my local machine, on Windows, the app is working without any errors

On my PC it also worked correctly in local development.

But we need to correctly build it on github pipelines, this is a bit more complicated, because imb_db package uses native JS module, which brings problems always. This job could not be easily delegated any of my colleagues, so it must wait, until there are no urgencies from Premium users and from DbGate investor

Hi @GergesBernaba1 ,

thanks for patience

There is apparantly problem with installing this package in electron, docker build works correctly - https://github.com/dbgate/dbgate/actions/runs/16340367906 , but electron build fails when installing packages - https://github.com/dbgate/dbgate/actions/runs/16340367905

I replicated this problem on my local computer with Windows OS, using commands:

node adjustPackageJson.js
cd app
yarn install

According to documentation, there should be precompiled packages, for electron, but they are not used

Electron Binaries - From electron v32 to v35. Hence, no support for vscode older than v1.95.

@GergesBernaba1 It worked locally for you even under electron ?

Did you install packages for electron? ( yarn install in "app" subdirectory)

yes i did

If it works for you, could you please send me console log, when adding ibm_db package to electron app?

cd app
yarn add ibm_db

I ended with following error, I would like to know, whether your install process used precompiled package for electron:

yarn add v1.22.19

i have to set this before run it:
$env:IBM_DB_HOME="{current Loction for app}\dbgate\app\node_modules\ibm_db\installer\clidriver"

and add those if not in the package JSON file:
"ibm_db": "^3.3.2",
"odbc": "^2.4.9",

And in the main, in the same file:
"@electron/rebuild": "^3.2.10",
"node-gyp": "^11.2.0"
"electron": "22.3.27",
and downgrade the electron version, or pull the latest

@janproch are you checking it?

I am trying to upgrade to newest stable electron 37 now, I hope it will help solve issues like this

@janproch Are you still waiting for any modifications from me?

@GergesBernaba1 plugin is OK, the problem is with the DB2 native NPM package, which breaks electron app installation. I have no idea how to solve this, probably big upgrade of all dependencies could help, but for this big upgrade we have curreclty no free capacity

Problem is the build process

But the number of probles regarding old electron is growing (eg. #1243 ), maybe we have to make finally un upgrade, which probably will solve problem with DB2 plugin build

Electron was succesfully upgraded, but ibm_db driver doesn't seem to install. I also upgraded to newest version ibm_db, without success. Installing this package fails on build server:

@janproch

Please review this PR: #1309
I've resolved the workflow issues.

@GergesBernaba1 thanks for the update

I added GH action
- name: Install ODBC
run: sudo apt-get update && sudo apt-get install -y unixodbc-dev

But there is the same problem when running yarn install

https://github.com/dbgate/dbgate/actions/runs/20719819077/job/59480310086

@janproch could you run it again?
