Actian Zen Background

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

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!


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


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


Curbing Performance Anxiety

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


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

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


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(www.goldstarsoftware.com/btrvload.asp)

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


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)


Common Causes of Slowness


▪Cause: CPU Running Slower than Rated Speed▪Verify: Run CPU_Z Test Tool

https://www.cpuid.com/softwares/cpu-z.html

▪Solve: Check BIOS Settings–Disable Power Management

▪Solve: Check OS Settings–Set to High Performance



▪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



▪Cause: L2 Cache Thrashing▪Verify: Excessive Page Faults Seen in Task Manager▪Solve: Disable L2 Cache in Config



▪Cause: Slow Disk Subsystem▪Verify: Use Process Monitor to See Disk Access Times▪Solve: Reconfigure Disks or Replace Server!



▪Cause: Excessive Network Latency▪Verify: Capture Network Traffic with Wireshark▪Solve: Redesign Network to Cut Latency
