Accelerate your Exadata deployment With
the skills you already know Marc Fielding September 2013

this presentation
5.
So you have
Exadata. What next? • Underpinning Exadata are well-known Oracle technologies • SQL*Plus works just like on any other Oracle system • RAC and Grid Infrastructure, 11gR2 (or 12c!) • ASM is there • Services, SCAN, etc no different than other Oracle RAC environments © 2013 Pythian5
6.
So what is
different? • It’s an engineered system: you run the same hardware as other Exadata customers • Oracle development has tested on the exact same configuration • It’s a good thing: much fewer obscure OS issues, driver issues etc • Single point of contact at Oracle support – hardware and software • And yeah, there are are a few new concepts… © 2013 Pythian6
7.
© 2013 Pythian7 Storage
servers Management switch Compute servers Empty space InfiniBand switches KVM
8.
The bits you
know already • It’s running Oracle database software • Database servers: Xeon-based servers running Oracle Linux 5 • 2, 4, 8- or more-node 11gR2 RAC cluster • Clustered ASM instances • Ordinary Ethernet connections to the outside © 2013 Pythian8
9.
The secret sauce •
InfiniBand networking – Gives amazing latency: forget 1ms, try 1µs – Great capacity too: 40gbps – Used for RAC interconnect and storage access – replaces fiber channel • Storage servers: also Linux servers – But they run Exadata-specific software – Take I/O requests from database servers and send to disk – Also have understanding of database concepts © 2013 Pythian9
10.
Differences from SAN/NAS •
No single “storage head” – storage management is handled by the ASM cluster instead • Easy scaling: when you add storage capacity, you get processing capacity too • Switched network increases network capacity as you scale • Usually dedicated database storage, so often managed by DBAs too • Hot/cold storage: tier outer and inner tracks on a disk © 2013 Pythian10
11.
Smart Scans (1) •
Somewhat analogous to parallel query • Multiple parallel processes • Communicate with shadow processes with SQL-type constructs – rows, columns etc • Save communication capacity by only sending the data you need, not entire data blocks • select col1 from big_table; • Sends only col1 data, for example • Also more complex actions like predicate evaluation, decryption, bloom filter joins… © 2013 Pythian11
12.
Smart Scans (2) •
Put processing closer to the storage • Inherently parallel: processing happens on all storage servers that might have matching data • Only apply to bulk, direct path operations – usually full table scans • Excludes – Index range scans – Table access by index rowid – Blocks with uncommitted changes – LOBs © 2013 Pythian12
13.
• Used in
conjunction with smart scans • Can avoid doing I/O entirely • Split storage up into 1m “storage regions” • Track high/low values • Work best with pre-sorted data • Example: select * from tab where col1 < 20; © 2013 Pythian13 Storage Indexes 2-99 4-57 33-60 90-120
14.
Hybrid Columnar Compression
(1) • New storage type with superb compression ratios: 10x or more • Group blocks into compression units • Store columns together instead of rows • Typical databases have repeated values: the infamous “Y”/”N” column for example • Then apply well-known compression like bzip2 or gzip on top © 2013 Pythian14
15.
Hybrid Columnar Compression
(2) • Much like smart scans, data must be loaded in bulk: CREATE TABLE AS SELECT, INSERT /*+APPEND*/, SQL*Loader direct path, etc • Otherwise data will get OLTP compression instead • CPU overhead to compress/decompress (though smart scans can offload decompression) • Locks affect entire compression units rather than single rows © 2013 Pythian15
16.
Recommendations: HCC • Best
for data that is inserted in large batches (data warehouses for example) • Also useful with time-based partitions: re-compress old, no-longer-modified data • There are 4 levels; ARCHIVE HIGH has significant CPU overhead so use for data that’s rarely accessed • Use DBMS_COMPRESSION to predict compression ratios, and see results afterwards © 2013 Pythian16
17.
Flash cache • Designed
for OLTP • Flash memory has 5x better read latency than hard drives • Transparent to applications • Smart enough not to cache RMAN backup I/O, ASM secondary extents, and other non-repeatable reads • DBAs can use resource manager and SQL to prioritize cache objects © 2013 Pythian17
18.
Flash cache: recommendations •
With new Exadata X3, you may fit entire DB in flash. Enjoy! • Entirely different from the similarly-named Database Smart Flash Cache in 11gR2 • You can put ASM disks on flash, but ASM redundancy reduces usable space • You can use back-end commands to actually see what’s being cached © 2013 Pythian18
19.
I/O Resource Management •
You can use DBRM in Oracle 11g to manage CPU time, and manage runaway queries • But what if your system is bottlenecked on I/O • In Exadata, just turn on IORM and your CPU priorities apply to I/O too • Can also allocate I/O capacity across databases © 2013 Pythian19
20.
Management tools • OEM
12c: put a lot of work into managing Exadata • Can now manage all Exadata components (incl switches etc) • Consolidation planning tools to evaluate workloads © 2013 Pythian20
21.
Management tools (2) •
Command-line tools all there: SQL*Plus etc • For storage servers, a new tool: cellcli to manage storage servers • cellcli can be combined with dcli to run a command on multiple machines. • cellcli changes to one storage server aren’t visible to others © 2013 Pythian21
22.
Hardware management • Like
other enterprise hardware, Exadata has out-of- band management • ILOM lets you access hung servers without driving to the datacenter • Very useful when doing patches and reboots • Monitors system health and can send alerts when metrics are out of range • Most configuration changes made thorough Exadata cellcli © 2013 Pythian22
23.
Backups • Backups run
through RMAN – no snapshot support • Similar RMAN configuration to non-Exadata • Use high-speed InfiniBand network if you can • Oracle ZFS appliance can be configured for InfiniBand for example • Use IORM to manage backup I/O to avoid performance degradation at backup time • Use multiple channels to keep the disks busy © 2013 Pythian23
24.
Disaster recovery • No
storage-level replication like SRDF • Data guard is the overwhelming favourite • Active data guard works well with Exadata • Non-Exadata standby: watch HCC • Most common approach: two datacenters with identically configured Exadata machines © 2013 Pythian24
25.
Data migration • Like
backups: no storage-level replication • Physical copies – Data guard physical standby – Transportable tablespaces – Cross-platform incrementals • Logical transfers – Data Pump – Direct path over DB Link – GoldenGate – Data guard logical standby – External tables / SQL*Loader © 2013 Pythian25
26.
Patching • Exadata has
many components • All of which have periodic patches • Major work has been done to improve patching • Recommended quarterly full-stack patches include patches for all equipment • Do not apply CPU/PSU patches – Exadata bundle patches include security fixed, plus high-priority bug fixes • Different patching options involve different levels of downtime, data-loss risk, and execution time • Review the options © 2013 Pythian26
27.
Diagnostic tools • exachk
is developed by Oracle development to compare your configuration with Oracle- recommended values • Large library of tests, and regularly being added • Good idea to run before and after system changes like patches or configuration updates • Download from My Oracle Support • Required root access for full information © 2013 Pythian27
28.
New Exadata install
– what to expect • PDF configuration questionnaire – How you want your system built out • Hardware requirements – Exadata is very dense – look at power, weight, cooling etc • Site survey • Equipment delivered • Hardware configuration • Software configuration • Installation report © 2013 Pythian29
29.
Decisions to make •
High performance / high capacity • ASM normal / high redundancy • Data/FRA storage split • Hot/cold diskgroups? © 2013 Pythian30
30.
Working with Oracle
Support • Oracle Support manages all Exadata components: database, hardware, OS, network • Even hard disk failures must go through Oracle Support for triage and troubleshooting • Dedicated engineered systems team handles front-line support • Much better experience than ordinary support • Ordinary support-management skills are doubly important though: creating SRs properly, escalations, etc © 2013 Pythian31
31.
Organizational support models •
Exadata blurs the lines • Oracle support procedures are new for admins used to dealing with other vendors • Generally most Exadata work is DBAs • Most common support model is to create a team with mostly DBAs to manage entire Exadata stack • Organizational reasons may require a more traditional model though • For you as a DBA: reach out © 2013 Pythian33
32.
But overall • As
a DBA, you’ll still be doing much the same work as you’re used to on Exadata • Performance tuning, backups, code deployments, disaster recovery all exist in Exadata land © 2013 Pythian34
33.
Gaining Exadata skills •
Not many of us have datacenters in our basements to try out new technologies • Learn technologies like RAC, and “real” ASM with redundancy, direct-attach disk • But there are plenty of resources: – Exadata courses: Oracle university workshop, and others – Exadata books, particularly Expert Oracle Exadata – Conference presentations – even if you can’t attend, try and download the slides © 2013 Pythian35
34.
A word about
the IOUG • The IOUG is bring you today’s user group day • By Oracle users, for Oracle users • Collaborate 2014: April 7-11, Las Vegas • Master class events this fall: Milwaukee, Rochester, Chicago, Atlanta • IOUG Kiosk: Moscone West, 2nd floor © 2013 Pythian36
