3 Actian Zen Background

4 What is Actian Zen? Actian Zen, formerly known as Actian PSQL, formerly known as Pervasive PSQL, formerly known as Pervasive.SQL, formerly known as Btrieve: Stores data for a wide variety of software solutions, in every vertical market imaginable Offers high speed, low overhead, database access to applications Provides both transactional (NoSQL) and relational (SQL) access models, giving developers the right tool for the job Requires no DBA to configure or manage, reducing operational costs Actian Corporation

5 What About Previous Versions? Zen has a VERY long history. Here are some previous versions: Pervasive.SQL 2000i: End of Support: July 1, 2004 Pervasive.SQL V8: End of Support December 31, 2006 Pervasive PSQL v9: End of Support: January 1, 2010 Pervasive PSQL Summit v10: End of Support: March 1, 2012 Actian PSQL v11: End of Support: July 1, 2016 Actian PSQL v12: Supported Through July 1, 2019 Actian Zen v13: Current product, Released June 2017! Actian Corporation

6 Benefits of Zen v13 Most Compelling New Features in v13 for End Users: PSQL Reporting Engine: Offloads SQL workload from main database server, providing horizontal scalability New Cache Management Functions: Pre-loads (or purges) cache blocks, optimizing engine performance after a restart Active Directory Security Integration: Simplifies SQL security by leveraging AD groups, simplifying implementation further Actian Corporation

7 Benefits of Zen v13 Most Compelling New Features in v13 for Developers: New SDK s and API s: Simplifies development learning curve and provides access from scripting languages (e.g. Python) New Developer Features: Adds TRY_CAST and TRY_CONVERT in SQL, & the new LIKE syntax on GetNextExtended operations New Platforms: Adds Windows Nano Server, Raspberry Pi, and Android environments to existing Windows, Mac and Linux solutions Actian Corporation

8 Curbing Performance Anxiety

9 Factors Impacting Performance Server Hardware Server Operating System Database Engine and Files Network Communications Workstation Hardware Workstation Operating System Application Design and Total Work-Load Actian Corporation

10 Hardware Performance CPU Clock Speed Number of Cores System Memory (RAM) Hard Disk Drives Drive Speed (RPM) Drive Throughput RAID Configuration Consider SSD for Boot High Speed NIC with TOE Actian Corporation and Goldstar Software Inc.

11 Operating System Performance Consider RAM Disk for Temp Files Consider AntiVirus Exclusions Disable Unneeded Services Disable OS-Level Firewalls Set High Performance Mode! Check BIOS Power Configuration Check Control Panel, Power Options Verify with CPU_Z Actian Corporation and Goldstar Software Inc.

12 Database Engine Performance Use the 64-bit Database Engine Use Lots of RAM for L1 Cache (Up to data size) Disable L2 Cache (The OS Can Mess With It!) Segregate Test Databases onto Test Servers Rebuild Data Files for 16K Pages rbldcli f95 p16384 c *.* Pre-Load Data Cache After Reboot BUTIL CACHE <filename> with Zen v13 BTRVLOAD *.* /T100 for PSQL v12 or Older ( Actian Corporation and Goldstar Software Inc.

13 Network Performance Use Wired Ethernet, Not Wireless! Use Quality Cat5e Cables (or Better) Key Is Latency, not Bandwidth! Minimize Workstation Server Distance/Time Check Latency with Wireshark If Latency is High, Use RDP/Citrix Actian Corporation and Goldstar Software Inc.

14 Application Performance Mainly Controlled by Software Developers More Data = More Work; Archive if Possible! Use Extended Operations Where Needed System Can Be Affected by Large SQL Reports Consider Using New Reporting Engine in Zen v13 SQL Query Optimization Is a MUST! All JOINs Should Use an Index Look for an Index for WHERE Clauses Avoid ORDER BY (when possible) Avoid Temp Tables (when possible) Actian Corporation and Goldstar Software Inc.

15 Common Causes of Slowness

16 Common Causes of Slowness Cause: CPU Running Slower than Rated Speed Verify: Run CPU_Z Test Tool Solve: Check BIOS Settings Disable Power Management Solve: Check OS Settings Set to High Performance Actian Corporation and Goldstar Software Inc.

17 Common Causes of Slowness Cause: Insufficient Cache Memory Verify: Review PerfMon Counter for L1 Cache Usage % Verify: Review PerfMon Ctr for L1 Cache Misses/Sec Solve: Increase Database Engine L1 Cache (If Possible) Solve: Pre-Load Cache Actian Corporation and Goldstar Software Inc.

18 Common Causes of Slowness Cause: L2 Cache Thrashing Verify: Excessive Page Faults Seen in Task Manager Solve: Disable L2 Cache in Config Actian Corporation and Goldstar Software Inc.

19 Common Causes of Slowness Cause: Slow Disk Subsystem Verify: Use Process Monitor to See Disk Access Times Solve: Reconfigure Disks or Replace Server! Actian Corporation and Goldstar Software Inc.

20 Common Causes of Slowness Cause: Excessive Network Latency Verify: Capture Network Traffic with Wireshark Solve: Redesign Network to Cut Latency Actian Corporation and Goldstar Software Inc.
