DB-7 Moving On Up - Smaller Servers and Bigger Performance

Who…

• Programming since 1978• OpenEdge v3.2A and Unix since 1986• Certified in AIX, HP-UX, Solaris, etc.• 35 programmers and DBAs• Contract programming and

consulting


Customer history• Chose Progress vertical app• Bought Unix for multiple users• Added on to grow• Kept machine forever


Results after 10, 15, 20 years

• Locked-in proprietary platform• Rarely upgrade to new model• Very expensive

– Training– Add-on hardware– software


Need to grow• More users, demands• More data to crunch• Ageing hardware• Increasing support cost


Moving on up• Upgrade servers• Modern platforms• 50% of cost of proprietary• Reach new features


Your direction• How many will buy new or

add?• Want fast, cheap, supported• Must be safe, risk-free• How do you decide?


Previously supported OSes

• DEC VMS• DEC Unix• MS-DOS• Novell Netware• CTOS/BTOS• Sequent

Dynix/ptx• Data General DG-

UX• SCO Xenix & Unix• SCO Unixware

• AT&T/NCR Unix• Unisys Unix• IBM AIX• HP-UX• Sun SunOS &

Solaris• MS Windows NT• RedHat & SUSE

Linux• AS/400


Current OSes and CPUs• IBM AIX on

Power• Linux

– x86– Power

• HP-UX– PA-RISC– Itanium

• Sun Solaris– SPARC– x86

• Windows Server– x86

• Tru64 on Alpha


OS and CPU trends• x86 – Intel Pentium AMD• Linux or Windows on x86

– Reduce costs– Shift most R&D costs to external– Focus on software and services– Standards rather than

proprietary


Benefits of x86-based• Lower initial costs• Lower support

costs• Increased

selection– Hardware– OS– Add-ons– Vendors– Resources

• Better performance

• Newer features sooner

• Virtualization• More timely

upgrades• Budget for

other options


Cons of x86-based• More vendors “in the mix”• Limited support for 3rd party• HW and OS support not as

deep yet• Servers not always as cool

looking


Costs of new platform• New hardware• New OS• HW, OS, and SW annual

support• Porting costs (consulting or

in-house)• Platform change fees


Solution comparisons


5-year costs and savings


Excellent cluster config


Question:• Ok, so it’s cheaper…• But is it faster?


CPU SPECint_rate2000

“performance measurements that can be used to compare compute-intensive workloads on different computer systems, SPEC CPU2000 CINT2000 for measuring and comparing compute-intensive integer performance.”

-www.spec.org


TPC-C• Transaction Processing

Council– www.tpc.org

• TPC-C benchmark for OLTP


Today’s TPC-C results

• Old days – big iron• Today - top fifty!


Important performance notes

• Database apps need I/O and memory speed, not so much compute speed– Memory and I/O bus speed– L2 and L3 cache size– Memory size– I/O speed and spread

• OpenEdge uses INT ops, not FP ops• Keep context switching to a

minimum


Change: What’s important?

• Vendor selection• Vendor support• Planning the migration


Vendor selection• Choose vendor you trust• Nearby parts and service• Solid Linux/Windows history

and investments• Enterprise relationship


Vendors and support• 24x7 enterprise support is

critical• Top-tier vendor

– HP, IBM, Sun, Dell• Align for Windows or Linux

Porting plan• Licensing issues – discover early• Validate portable code base, no

orphans• Catalog all services and products• Purchase and install HW and OS• Create bare-metal restore• Test new support contacts and

contracts


Porting plan (cont’d)• Install software, recompile and basic

test• Migrate users, printers, devices, data• User testing of functionality, external

interfaces• Nightly refresh• DR test• Parallel testing• Switchover and reverse refresh


Porting issues• UIDS and

Passwords• Profiles• Printers• Locations and

paths• Data

– Tar and untar– Dump&Load

• Scripts– Crontab vs.

Windows– Bourne shell vs.

bash vs. CMD.EXE

– Windows equivalents

• Rosetta stonebhami.com/

rosetta.html


Pitfalls to watch out for

• /dev/null• Serial ports• No Windows

telnet• Windows swap• Console

messages vs. Event Manager

• Online or LVM under Windows

• Search for “UNIX” or “OP-SYS”

• Sending email• Spaces in

filenames and paths

• Proprietary backup

• RAID 5• Not enough disks


Progress issues• Dump and load – endian-ness• .R OK with endian-ness, not

32 vs 64• Moving database

– Cannot use probkup– Binary dump and load OK– Character code conversion

• Disk layout and performance


End state


Virtualization• One physical machine

– Multiple OSes– Movable OSes

• Like partitioning• Dramatic trend towards

virtualization


Harlow’s “Fun with Virtualization”

• Why Virtualize?– Maximize utilization of server

resources– Provide higher availability– Simplify the testing of

upgrades/changes– Ease migration to new servers– Increase security– Reduce administrative workload


Recommendations• Project support and upgrade

costs• Consider move to x86• Consolidate platforms and

storage• Plan your architecture• Vendors with knowledge and

support• Test, test, test
