• Key Concepts: 
  Partition lock promotion is a feature of SAP ASE (Adaptive Server Enterprise) that allows for the promotion of locks from one partition to another. This feature is used to ensure that transactions are not blocked by locks on other partitions. It also helps to reduce the amount of time spent waiting for locks to be released. 
  
  How to use it: 
  Partition lock promotion can be enabled in SAP ASE by setting the “promote_lock_partitions” parameter to “true”. This will allow for the promotion of locks from one partition to another. It is important to note that this feature should only be used when necessary, as it can lead to increased contention and decreased performance. 
  
  Tips & Tricks: 
  When using partition lock promotion, it is important to monitor the system for any potential performance issues. If there are any issues, it may be necessary to disable the feature or adjust the parameters accordingly. Additionally, it is important to ensure that all transactions are properly committed or rolled back in order to avoid any potential deadlocks.
