Locks/Blocks/Deadlocks/Timeouts Guaranteed to happen! Focus on Blocks, because Timeouts and Deadlocks are the results of Blocks Who is blocking? What application area is blocking? When are blocks high? Leading to Improving indexes Re-designing application 31

Archiving Process 47 Live DatabaseArchive Database Archived Data Live Data trimmed compressed Archive Compress

How does it work? Example ‘big’ CRONUS database Archiving is done for Example focusses on G/L Entry

Before Archiving Drill down 2695 entries

After Archiving Compressed 61 entries Summary per G/L Account Month Dimension (set) Document No. replaced, Negative Entry No.

Before Archiving

After Archiving Dimension information is kept

Navigate Old Entries Should be done from the archive database

Navigate in the Archive Database Related documents available (depends on the scope)

Design Principles and Features 56 Original data never deleted Legal and fiscal requirements are met Any NAV table handling Customization, add- ons, base application Execution within same transaction Rollback if an error is encountered Fast T-SQL execution Compared to C/AL code in NAV The power of undo De-archive possible Dimension handling All functionality retained Link tables handling Orphans are not there Traceability – registers History of archiving retained Data visibility Historic data anytime available
