    Posted 03-21-2024 12:13

    User is reporting that Maximo is freezing.
    when moving between application and outlook or moving between tabs on a browser session.

    This is in happening in chrome and edge browsers

    Maximo Application version 7.6.1.3, Windows Server 2019.
    Just upgraded servers to windows 2019 from windows 2012.

    User 1 - In Maximo, moved to outlook, back to Maximo - freeze

    User 2 - Maximo, ran query, opened another Maximo tab, back to query Maximo tab - freeze.

    Anyone else experienced this issue?

    Diane,

    This is definitely a strange behavior especially if it is happening to multiple users. Here are a few things I would recommend to try to see if it clears the issue:

    1. Clear the browser cache and retry
    2. Use the developer tools on Edge or Chrome specific to the Maximo tab (Developer tools is active per tab). Have the console sub tab in developer tabs selected and see what it shows when you switch between tabs or switching between applications. 
    3. For User 2 that is opening a second Maximo tab make sure that they are not copying the entire URL from the first tab/session. It should only be https://<hostname>/maximo when they launch a second tab
    4. To eliminate the server side being the problem, I would stop the Maximo application (schedule an appropriate downtime) and clear the Websphere Cache. I am not sure how yoru upgrade was done, but there potentially may be some stale cache files. If you have not done this before here are the folders you need to clean out and there are a few IBM Technotes like this https://www.ibm.com/support/pages/about-clearing-websphere-70-90-cache-files-maximo-administrators
    Delete cached files from temp and wstemp and, optionally, logs directories:

    Windows (where the WebSphere location is C:\Program Files\IBM\WebSphere\AppServer, the application server profile is called ctgAppSrv01, the node is called ctgNode01, and the Maximo server is called MXServer). *.* means contents of the named directory:
    • C:\Program Files\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\temp\ctgNode01\MXServer\*.*
      C:\Program Files\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\wstemp\*.*
      (optional) C:\Program Files\IBM\WebSphere\AppServer\profiles\ctgAppSrv01\logs\MXServer\*.*

    5. Before your restart Maximo after clearing the cache I would re-run UPDATEDB to be safe. A re-build and Re-deploy would also be a good option. You typically would not need to but not knowing how the Windows Upgrade was done and what other changes may have happened it can sometime save you the hassle.

    6. One other item where I have seen many years ago was an Antivirus/Malware software a client installed. The corporate IT deployed a new software version which no one knew anything about and it caused havoc with the browsers and impacted Maximo. 

    Hope these suggestions help.

    Mike

    Hi Diane,

    are the users running the browser on client PCs or on other servers e.g. Citrix / Windows Terminal Servers?

    As Michael says it is worth checking the Console sub tab. It is also worth checking the Network tab to see if the browser is making calls to the Maximo server.

    If it is making calls to the Maximo server then you can start checking other things:

    • Slow SQL statements - Make sure your sql logger is set to WARN to log details about slow SQL statements
    • IHS logs indicating slow calls or calls that return a lot of data

    If you aren't about what to look for then reach out to me and I may be able to provide more support privately
