• What is the cause and solution for SAP error message DB6PM145 - Partition group &1 is still in use, deletion not possible ?

  The SAP error message DB6PM145 indicates that a partition group is still in use, which prevents its deletion. This typically occurs in the context of database partitioning, where certain partitions or partition groups are being referenced or utilized by ongoing processes, transactions, or database objects.
  Cause:
  
  Active Transactions: There may be active transactions or sessions that are currently using the partition group you are trying to delete.
  Dependent Objects: There could be database objects (like tables, indexes, or views) that depend on the partition group, making it impossible to delete until those dependencies are resolved.
  Locks: The partition group might be locked by a process, preventing any modifications, including deletion.
  Replication or Backup Processes: If the partition group is involved in replication or backup processes, it cannot be deleted until those processes are completed.
  
  Solution:
  
  Identify Active Sessions: Use database monitoring tools or SQL queries to identify any active sessions or transactions that are using the partition group. You may need to terminate these sessions if they are no longer needed.
  Check Dependencies: Review the database schema to identify any objects that depend on the partition group. You may need to drop or alter these objects before you can delete the partition group.
  Release Locks: If there are locks on the partition group, you may need to wait for the locking transactions to complete or manually release the locks if appropriate.
  Wait for Processes to Complete: If the partition group is involved in ongoing processes (like backups or replication), wait for those processes to finish before attempting to delete the partition group again.
  Use Database Tools: Utilize database management tools or transaction logs to get more insights into what is currently using the partition group.
