Error: NetScaler MAS database requires maintenance

1. Log  into MAS as nsrecover /password of nsroot user.

2. Run the following command to start the Database Maintenance script:
   nohup python /var/db_maintenance.py >/var/mps/log/maintenance.py.log&

3. Run the following command to monitor the status and complete status of the logs:
   tail -f /var/mps/log/db_maintenance.py.log /var/mps/maintenance.py.log 
   
   Once maintenance finish you will see these lines at the end of the maintenance log:
   [DEBUG] runCleanup returned result: 0
   [DEBUG] *************** CLEAN UP IS DONE *********************** 
    
   Note: Do not restart the system until the maintenance is completed

4. After the maintenance is completed, upgrade the mas using the ./installmas command. See steps below for upgrade to ADM 12.1_50.39.
   >> Connect to ADM using any secure copy tool [i.e. Filezilla, WinSCP, etc.]
   >> Navigate to /var/mps/mps_images/
   >> If you see the directory mas-12.1-50.39/ or the file build-mas-12.1-50.39.tgz were a good; otherwise, copy the file over.
   >> Connect to ADM using any SSH tool [PuTTY, SecureRT, etc] and type the following commands:
   > shell
   # cd /var/mps/mps_images/
   # mkdir mas-12.0-50.39     *** Only needed if the directory doesn't exist already ***
   # tar zxvfp build-mas-12.1-50.39.tgz -C mas-12.0-50.39   *** Only needed if you had to copy the file over the ADM. ***
   # cd mas-12.0-50.39/
   # ./installmas
