2950474 - DB table growth in SAP Hana related to Packed LOB's


  • In SAP Hana Database, you encounter an issue where disk space is growing
  • Even after cleanup of table data and reclaim as per SAP KBA 2696420 How to Manually Reclaim LOB space on Hana, the /hana/data size does not decrease significantly
  • Perhaps the table involved is already known to you, but if not you can run the HANA_Tables_LargestTables_* query from note 1969700 SQL Statement Collection for SAP HANA
  • In the column LOB_DISK_GB, you can identify a large amount of space is taken up by LOB data
  • To further drill down on the type of LOB data, execute the HANA_Disks_Data_Overview_* script from note 1969700
  • Here you find a significant portion of the space is related to Packed LOB data i.e. column PLOB_GB
