As of December 1, 2020, Focal Point is retired and repurposed as a reference repository. We value the wealth of knowledge that's been shared here over the years. You'll continue to have access to this treasure trove of knowledge, for search purposes only.

New TIBCO Community Coming Soon
In early summer, TIBCO plans to launch a new community—with a new user experience, enhanced search, and expanded capabilities for member engagement with answers and discussions! In advance of that, the current myibi community will be retired on April 30. We will continue to provide updates here on both the retirement of myibi and the new community launch.

What You Need to Know about Our New Community
We value the wealth of knowledge and engagement shared by community members and hope the new community will continue cultivating networking, knowledge sharing, and discussion.

During the transition period, from April 20th until the new community is launched this summer, myibi users should access the TIBCO WebFOCUS page to engage.

[SOLVED]Permanent hold files vs database views

I am new to WebFOCUS, so please let me know if I am not using the proper jargon.

My boss wants to replace permanent hold files with database views in Oracle. I have been asked to research the pros and cons of this approach. Our hold files contain anywhere from a few hundred records to a few million records. So, I would appreciate any feedback that I can get.

Thanks.
Raj

What's the format of your HOLD files? Are you creating HOLD FORMAT FOCUS files?

Looking at the code, it looks like we are creating HOLD FORMAT XFOCUS files.

So, the data is stored in .foc files on disk not in a DBMS like Oracle. You can back them up just like any disk file. No need to go through the DBMS backup and restore procedure. They are also much easier to transport from one directory to another. The advantage of putting these extracts in a DBMS is that they'll be a part of back up process and you won't need to deal with them separately. FOCUS hold files may also have a little less overhead in processing because you don't have the DBMS involved. That might not necessarily be noticeable. The main question is why does your boss wants this done? Does your boss think there's a specific benefit?

One of the reasons is that we have had numerous issues in the past few months where the permanent hold files would not get refreshed and we would end up with old/no data.

But I think the main reason is that we are trying to refactor our datamart and properly stage the data we need at he database level. So, if we are doing all this work at the database level, my boss wants to know why we need to maintain datasets both in our datamart (as views) and as permanent hold files.

That's a very good reason. Usually, these hold files are used for quick caching of data or transformation of data that's hard to report from. I've also seen very complex code that almost functions like ETL which ends up putting the answer set in a hold file for reporting. If you are creating a dimensional model and going through the process of creating a DM, then it makes sense to eliminate the hold files so you only have a single source of the truth but still utilize hold files when they make reporting convenient.
