Resource management is like having a budget – the simpler it is, the higher chance to be followed.<\/p>\n

CPU <\/strong>
\nEven if you overubscribe with instance caging, it’s still much better than no resource manager. <\/p>\n

On Linux and Solaris, 12c allows you to bind some databases to specific CPU cores or sockets, if you are so hard-core and you have super-super critical DBs (or NUMA)<\/p>\n

IORM <\/strong>
\nWith mixed workload, OLTP may get some really slow IOs when DWH kicks in (even up to a second per IO). That’s why IORM protects the latency of OLTP by putting OLTP io requests in front of the queue (otherwise we have FIFO)
\nTo make this, the DB tags every io request with various info. E.g. OLTP is put in prioritized queue, LGWR is out even higher – at the very top, large DWH reads are put with lower priority<\/p>\n

Standby DBs <\/strong>
\nBest practice – use the same resource plan as on primary (CPU and IO)\n<\/p><\/blockquote>\n

\nThere are no predicates on fact table. All filters are on dimensions
\nConstraints<\/strong>
\nAlways put Not null constraints on join keys – helps optimizer
\nPut PK and FK constraints. If you do th constraints in RELY mode, remember to enable query_transformation in RELY mode
\nData types<\/strong>
\nMake sure data types between parent and child match (incl. precision)
\nStatistics<\/strong>
\nDo not rely on dynamic sampling
\nThink about correlation
\nEnable column usage tracking. Gather stats after data load, and again after some real usage, to get extended stats
\nPartitioning<\/strong>
\nPartition fact table on time dimension<\/p>\n

Star transformation with bitmap indexes is great for extracting relatively low number of rows from fact table
\nExadata smart scans and bloom filters are much better for retrieving big amount of data from fact table
\nIn-memory with vector joins is good for big volumes. Actually vector joins are available even for non-inmemory at 12.1.0.2<\/p>\n

Snowflake <\/em>is much slower than star
\nCardinality estimations is much less accurate, much more unneeded data is moved during joins, etc.
\nTry hard to go to star, e.g. with mviews<\/p>\n

Links between dimensions are also bad. Never join dimensions. Note: DWH is not intended to enforce business rules!<\/strong><\/p>\n

Never use same dimension key to join to more than one dimension. Each dim should have its own dk\n<\/p><\/blockquote>\n

\nData management <\/strong>
\n– fast population of data – prepare aside and exchange partition
\n– fast removal of data – truncate\/drop partition
\n– fast reorganization of data (compression, movement, etc)<\/p>\n

12c new features<\/strong>
\n– merge more than two partition
\n– split to more than two partitions
\n– move partition fully online – allows all concurrent DML, takes care of global and local indexes
\n– async global index maintenance during DROP and TRUNCATE partition. Partition maintenance is metadata-only operation. Data stays in index, index stays valid, no wrong results, etc. Data can be cleaned later by ALTER INDEX REBUILD\/COALESCE
\n– partial local and global indexes<\/p>\n

Tips and tricks for 12c<\/strong>
\n– gather stats on to-be-exchanged table, do the exchange, global partitioned table stats are automagically updated
\n– do online move during low-load time. During the move, a journal of changes is kept. The smaller the journal, the faster move completion. Note: first part of move is direct-path, so can compress, but journal apply is row-by-rows <\/p>\n

General tip<\/strong>
\n– try to combine multiple partition maintenance operations into one
\n– use partition extended bulk load syntax – puts X-lock only on intended partition, not whole table. Careful with data cleanness\n<\/p><\/blockquote>\n

\nRAT = response time testing + load testing
\nSQL performance analyze (sqlpa) allows automatically to create tunning task for statements with degraded performance, or to create baselines for them<\/p>\n

– Always use sqlpa first, to fix individual queries, before running real load test (database replay)
\n– capture and replay manageable amount if time – 1-2 hours
\n– key metric of database replay is DB time, not elapsed time
\n– capture SQL tunning sets during capture and replay for additional validation
\n– use OEMCC with the very latest database plugin – implements best practices for RAT, new wizards, etc.\n<\/p><\/blockquote>\n

\n– Implementation is teamwork – DBAs, Sysadmins, net admins, etc.
\n– AAMROK is taking care of hi tech weapons of Abu Dabi – Jet fighters for example. You cannot take care of F16 using SQL Server, righ?
\n– Sprint have had the biggest single-node oracle database – 1.5 petabytes. Keeps 2 years or CDR data.
\n– AmericanAirlines made PoC on SuperCluster provided by oracle. Worked great, and they purchased it and went live<\/p>\n

Engineered systems are organizational challenge. Who owns the box – storage admins, sys admins, net admins, DBAs? Usually DBA volunteer
\nEngineered systems have great supportability. No finger pointing, everything is clear. Ease of deployment and configuration. You can focus on business\n<\/p><\/blockquote>\n
