2 What s New Larger alpha item size & larger record size Persistent RSN Reduced fine-table locking Remote Database Backup Automation Database Operations Center Enhancements 2012 Unisys Corporation. All rights reserved. 2

3 Larger Alpha Item Size & Larger Record Size Maximum alpha item size increased from 2**12-1 (4095) bytes to 2**16 1 (65535) bytes Maximum record size increased from 2**12-1 (4095) words to 2**16 1 (65535) words 2012 Unisys Corporation. All rights reserved. 3

4 Persistent RSN RSNs can be preserved across database reorganization SYSTEM/BUILDREORG Option KEEPRSN If SET, preserves the RSN value of new records created during a USEREORGDB reorganization If RESET the reorganization guarantees the uniqueness of RSNs for data set records but does not guarantee that old RSN values are preserved Default: RESET Example: GENERATE EMPLOYEES KEEPRSN; 2012 Unisys Corporation.

5 Reduced Fine Table Locking Current behavior DMSII removes a set entry immediately upon deletion Fine table is locked until transaction is completed or aborted May cause unnecessary blockages and even DEADLOCKs if multiple programs are deleting entries in the same or adjacent tables New DASDL NOFTLOCK option Set entries are marked for deletion Fine table does not have to remain locked for duration of transaction Entry is logically deleted in the eyes of other programs Other programs trying to insert or lock related records are no longer blocked 2012 Unisys Corporation.

6 Reduced Fine Table Locking Only available for XE Disjoint Index-Sequential Set DUPLICATE option must not be set Deleted set entries not automatically removed Use On-Line Garbage Collection (OLGC via Visible Database Command) -or- Garbage Collection via DMSII Reorganization procedure 2012 Unisys Corporation.
