We deleted entries in the DBTABLOG table for log entries of the custom table using RSTBPDEL. After the deletion, the following commands have been executed: ALTER SYSTEM RECLAIM COLUMN LOB SPACE; CALL CHECK_TABLE_CONSISTENCY('REPAIR_HYBRID_LOB_OVERHEAD', 'SAPHANADB', 'DBTABLOG'); ALTER SYSTEM RECLAIM DATAVOLUME 120 DEFRAGMENT; hdbcons 'dvol shrink -o 120' hdbcons "dvol sbtouch -n 100" then hdbcons 'dvol shrink -o 120' Additional steps: a. MERGE DELTA OF "DBTABLOG" FORCE REBUILD; b. UPDATE "DBTABLOG" WITH PARAMETERS ('OPTIMIZE_COMPRESSION' = 'FORCE'); c. ALTER SYSTEM RECLAIM DATAVOLUME 120 DEFRAGMENT; Despite all commands, the /hana/data is still the same. Please see the attached file for reference.
