Managing TM1 database assets with Git

Post by Nitrel »

Hello Community,

i am searching "RedBook" or "BestPractise" or any deepdive-samples how we can use GIT (BitBucket) and TM1 (Planning Analystics)
Is there any experiance around?

After several testing with Bitbucket, I don't think PA is mature enough to integrated with Git at this stage (We are on PA 2.0.8).
With those documents from IBM, you will find yourself struggling with the syntax of tm1project file eventually. Yes, it can do a few things with Git but very hard to use. :?
In TM1,the answer is always yes though sometimes with a but....

Do you mind sharing what in tm1project file was confusing?

I agree it's very far from intuitive, it's more of an API to build future tools on, but I still think it's quite useful even in the current shape.
Maybe it's the case when of having more examples out there might help, especially for tm1project?

Hi, ykud
Yes, I agree with the point that it is an API which some tools can build on. But the questions I have so far are
1. How to use Objects section in tm1project file rather than use Ignore section all the time to include/exclude objects?
2. How to use Pre/PostPull, Pre/PostPush, Dependencies/Preconditions and Links? The examples in IBM document are very raw and hard to understand.
3. Is it possible to hot promote cube data files via this method? I can push/pull the data files but looks like I have to reboot the tm1 server to get data file loaded.

Overall, I don't see any detailed examples from IBM apart from some detailed articles from other developers.
In TM1,the answer is always yes though sometimes with a but....

I agree with you that the documentation is very lacking and those examples leave you more confused than they explain how to use it.

And answering #3 the official answer from IBM support is NO, manually including the .cub files in the "files" section in tm1project and then doing a server reboot after a GitPull is not recomended by IBM, that's what they told me when I opened a support ticket. Also If we have .cub files over 100MB it won't upload to free git servers like github for example.
So we have to create a process that loads the attribute values from a file somewhere. One more thing to version and ensure that the file is updated with the latest values. Very disappointing. :x

Also, github is deactivating the basic auth that the tm1git uses to connect to their server in august 2021. Now they'll only accept tokens or SSH Key authentication, but tm1git doesn't have support for that!

Hi,
did you manage to connect to Github via SSH?

I get response:
"error": {
"code": "278",
"message": "Invalid parameter in payload \"PublicKey\". GitInit failed."
}
And I followed instructions from IBM pages:

{
"URL":"git@github.com:username/repository.git",
"Deployment":"main",
"PublicKey" : "ssh-ed25519 xxx",
"PrivateKey" : "-----BEGIN OPENSSH PRIVATE KEY-----xxx-----END OPENSSH PRIVATE KEY-----",
"Passphrase" : ""
}

Yep, works for me, but you need the 2.9.0.4 or later ( https://www.ibm.com/docs/en/planning-an ... er-17-2020 )

Works for us as well. Unfortunately it is only possible to use ssh for all users or for none. That is a bit annoying.
There is no OLAP database besides TM1!

I've been messing around with GitHub and PA Cloud and it seems to be working well. I did a video to help share what I did to make it work.
