The Developer Toolbar in APEX Application Disappeared

If the Developer Toolbar (shown below) in your Oracle APEX application is not displayed, you can control its display by changing the Status attribute on the application’s Edit Definition page.

I’ve learned about this when somehow one of our applications suddenly did not display the Developer Toolbar. We found out later that during environment refresh, the deployment team switched the Application’s Availability Status to Unavailable before the refresh and then back to Available after it’s done – not realizing that it was initially Available with Edit Links.

No harm done – just temporary inconvenience from Developer’s standpoint. 🙂

    Does anyone know of a way to programmatically (e.g. via PL/SQL)
    control the APEX Application “Availability Status” setting?

    Kindly explain what I should do.

    Should I make the status initially available instead of available with Edit Links?

    Since after clicking on one of the applications then moving to a different tab, the developer toolbar disappears and there is no way to edit the status when inside of this application

    Please advise

      I think you should have it available. I’m not sure why it disappeared. Did it occur consistently on other environments you have?
