Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Status Is a defect
Workspace Planning Analytics
Created by Guest
Created on Apr 24, 2020


There is a problem with the TM1 Web session management

resulting from use of TM1Web content in Planning Analytics Workspace

(PAW). Each time PAW content containing TM1 Websheets is opened, new TM1

Web sessions with the TM1 Server are opened (as observed in TM1TOP/Ops


New TM1 Web sessions continue to grow as additional PA Workspace content

containing TM1 Web components are closed/reopened. Seems to add a new

session for every tm1web component in the workbook. The sessions also do

not get closed when a user logs out of PAW, which are causing excessive

RAM/resource utilization in both TM1 Web and TM1 Server (especially when

scaling PAW to many users).

This has been reproduced in PA 209 and PAWorkspace 49. Can be reproduced with the 24Retail model.

Steps to reproduce:

1. Create (or use existing) a tm1websheet

2. Create a new workbook in PAW with the tm1websheet(s)

3. Open the paw workbook, multiple tm1web sessions will be created for all the tm1web objects

4. Close and reopen the workbook, multiple more tm1web sessions will be created

5. Over the period of time Tm1Web threads are accumulated in the Tm1. Can be seen using tm1top and PA Administration.

Ideally, the sessions should be closed once websheet is executed in PA Workspace.

    Agreed that this should be opened as a defect with IBM Support. Setting enhancement request status to Is a defect.

    this should be treated as a defect IBM, not as a product enhancement!
