  • Deactivated all users in Appian environment, how to fix?

    Background

    As part of a user story to Deactivate Users Who Have Not Logged In Recently, we set the value for Idle User Deactivation Duration (Days) as 1 day.
    This caused all the users to be deactivated after 1 days of inactivity including system administrator accounts.
    We were not able to login using any of the user accounts as a result.

    Fix

    1. Reached out to Appian support about this issue
    2. Appian support provided a zip file called “ASTM_Appian_Support_Tools_Manager.zip (10.54 MB)”
    3. Download the attached file “ASTM_Appian_Support_Tools_Manager.zip” and unzip it into /opt/appian/latest/_admin/_scripts
    4. Some next steps to follow:
      3.1. Go into the folder: “cd /_admin/_scripts”
      3.2. Enable permission: “chmod +x ./executeAppianSupportScript.sh”
      3.3. Run the following command: “./executeAppianSupportScript.sh reactivateusers –usernames site-admin”
    cd  /opt/appian/latest/_admin/_scripts
chmod +x ./executeAppianSupportScript.sh
./executeAppianSupportScript.sh reactivateusers --usernames site-admin
    Inside the ASTM_Appian_Support_Tools_Manager.zip
    Inside the astm directory

  • How to check the appian product license expiry date

    /opt/appian/latest/server/_bin/k/linux64

    I am getting k3.lic as the output when I run k.exe under /server/_bin/k/linux64. I know that it indicates that the license is invalid and it might have been expired. But there are other factors which can make a license invalid.

    The license for this environment is invalid for at least one of the following reasons:

    There was a change in the operating system.
    There was a change in the CPU count.
    The FQDN was changed.
    The license expired.
    More than one hostname resolves to the local network IP of the machine where this license is installed
    So I want to know that if the license expiry is the reason in my case. How can I check the expiry date for the license?

  • L1-L6 Engineers

    L1 engineers are entry level engineers who can complete assigned engineering tasks under guidance.

    L2 engineers are competent individual contributors who can work comfortably with engineering tools, run systems in production, prioritise engineering tasks for themselves, and complete them independently.

    L3 engineers are fully proficient individual contributors who can provide technical leadership to teams. These engineers can devise the architecture of the projects, break it down into engineering tasks, and make rapid progress on the tasks.

    L4 engineers are prolific individual contributors who can proactively identify, initiate, and coordinate worthwhile engineering projects for the organisation to pursue. These engineers have deep expertise in at least one technical domain and are comfortable working with people across the organisation.

    L5 engineers provide critical engineering leadership of the organisation. These engineers can create a long term vision for what the organisation should be building towards and structure the groundwork for building projects to get there.

    L6 engineers are leading experts in their field of technical expertise. These engineers exert strong technical influence and leadership in the engineering field and community. They contribute to the organisation by providing deep technology expertise to develop and implement major high impact tech initiatives, provide technical leadership and mentorship to other engineers, and serve as talent anchor for the organisation to attract other tech talent.
