You can use these Oracle Capacity planning and Sizing Spreadsheets. For something not quite as full-blown, if you just want back of the envelope type rough estimates for the index. Calculate the average size of each of the columns that make up the index key and sum the columns plus one rowid and add 2 bytes for the index row header to get the average row size.
Research BC Oracle Websites!Oracle Capacity PlanningOracle Guidelines by Burleson ConsultingIntroduction - DatabaseAdministrationThe easiest method to perform Oracle capacityplanning is certainly with the Oracle. Database Administration offers developed over theyears from the mere management of a several tables and indexes tó acomplex interlocking set of obligations ranging from managingdatabase items to taking part in business wide choices onhardware, software program and growth equipment.In purchase to fully carry out these features themodern Oracle DBA requires a large skill place.
Over the following few hours wewill discuss the skills required and specifically how they use to anOracle DBA.Program Capacity PlanningIn a natural field procedure (one where yóu arethere before thé gear and data source) a DBA will have a criticalpart to enjoy in the planning and configuration of the brand-new program. Evenin existing conditions the ability to program for new computers, newdatabases or enhancements to existing databases and techniques iscritical.Essentially the DBA must concern themselveswith two main issues:.Get enough machine to guarantee adequateperformance.Allow for enough backup and recoveryhorsepower to get backup and recovery carried out within the requiredtime constraints.All of this in fact drops under the topicrésource and capacity pIanning.Resource and CapacityPlanningOracle will be a source strenuous databasesystem. The more memory, Central processing unit and cd disk resources you can provideOracle, the better it performs.
Reference planning with 0racle becomesmore a game of 'how significantly can we afford to purchase' instead of 'what is usually theminimum settings'. A minimally configured Oracle server will notfunction in an efficient manner.Source Specification for OracleIn reference specification generally there are usually severalquestions which must be answered.How numerous users will be making use of the system bothnow and in the future?.How much data will the system consist of bothnow and in the potential, perform we understand growth prices?.What response times are usually anticipated?.What system availability will be anticipated?Why are these questions important?1.
How many users will end up being using thesystem both now and in the future?This query is essential because it effectshow very much processing strength is heading to end up being needed. The quantity of userswill determine quantity and speed of CPUs, dimension of memory, networkrelated construction.2. How much data will the program containboth right now and in the potential, do we understand growth rates?This issue is essential because itdetermines drive needs, how very much storage will end up being required to take datawe have today and how very much will become needed to enable for development. Theanswer to this question also helps determine how much storage will berequired.3. What response times are expected?This query is important because it drivesnumber, kind and velocity of Processor resources as properly as network issues. Inaddition it will drive disk configuration issues such as quantity andspeed of disks, amount and speed of controllers, disk partitioningdecisions.4.
What system availability is usually expected?This question is essential because systemavailability runs the type of RAID settings (1, 0, 0/1, RAID5),the type of backup expected (frosty, sizzling) and any paraIlel serverissues. The needs transformation if all that will be expected can be the systembe obtainable during functioning hours Mon through Fri or if thesystem is expected to end up being obtainable 24X7 seven days a week. This alsodrives the kind of backup mass media, whether a single tape travel can be allthat is definitely required or perform we require a hi-spéed, multichannel, tape-stackér,silo based solution?To properly execute capacity planning acooperative effort must become carried out between the systemadministrators, database managers and network administrators.Action 1: Size the Oracle databaseA beginning point for the entire procedure ofcapacity planning is to understand how numerous and what dimension directories will besupported on a given server source. The bodily sizing of tables,indexes, groupings and LOB storage space areas will play a important part insizing the overall database like the provided global memory areasand disc farm. The DBA and designers must function in conjunction toaccurately size the data source physical documents.
The design of thedatabase will furthermore generate the positioning and amount of tablespaces andother data source resources like as size and amount of redo logs,rollback segments and their linked buffer locations.Generally the data source block buffer locations of adatabase SGA will size out at bétween 1/20 to 1/100 the actual physical sumof the complete quantity of data source file sizes. For instance if thedatabase bodily size is 20 gigabytes the data source mass buffersshould dimension out to aróund 200 megabytes to 1 gigabyte in sizedepending on how the data is becoming used. In many situations the SGA sharedpool would dimension out at aróund 20-150 megabytes maximum depending onthe usage model for the distributed SQL areas (covered in a later on lesson.)For a 20 gigabyte program the redo records would almost all likely work between20 and 80 megabytes, you would wish them mirrored and probably nofewer than 5 organizations. The sign buffer to support a 50 megabyte redo logfile would be a least of 5 megabytes probably simply because large as 10 megabytes.The last major element for the SGA would end up being the dimension of the kind area,for this dimension of a database a 10-20 megabyte kind area can be about right(based on the number and size of types). Remember that sort areascan either become a component of the contributed pool or a part of the large swimming pool,this as well we will protect in a later on lesson.So structured on the over what have we driven?Lets choose 400 megabytes for our database block buffer size, 70megabytes for the discussed pool, 4-10 megabyte log buffers (40megabytes) and a kind area size of 10 megabytes. We are usually looking at a500-600 megabyte SGA with the various other non-DBA substantial factors included in.Since you are not intended to make use of even more than 60% of bodily memory(depending on who you question) this indicates w will need at least a gigabytéof RAM.
With this size of data source a single CPU possibly won?capital t givesufficient efficiency so we are probably searching for at least a4-processor machine. If we have got more than one instance installed onthe server, the storage requirements will proceed up.Stage 2: Determine Number and Kind of Customers:Naturally a one user database will requirefewer sources than a thousand consumer database. Generally you will needto take a SWAG at how very much memory and disk resources each user willrequire.
An example would become to presume that of an installed user baseof 1000 users, just 10 pct of them will be concurrently using thedatabase. This results in 100 contingency customers, of those maybe a 2nd 10percent will be doing routines that need sort locations, this bringsthe number down to 10 customers each making use of (from our earlier illustration) 10megabytes of memory each (100 megabytes.) In inclusion each of thé 100concurrent users needs around 200k of process room (dependingon exercise, Operating-system and other factors) so we are talking an additionalload óf 20 megabytes simply for consumer process space. Finally, each ofthese customers will probably require some quantity of storage reference (lessif they are usually client-server or web based) let?s give them 5 meg of diskto begin each, that provides up to 5 gigabytes of cd disk (give or get ameg or two.)Step 3: Determine Hardware Specifications toMeet Required Response Occasions and Assistance User Load:This action will include the systemadministrator and perhaps the equipment vendor. Provided our 1000:100:10mix of customers and any needed response periods figures they should beabIe to configure á machine that will provide proper efficiency.Generally this will require multiple, multiple-channel disk interfacesand various physically separate storage arrays.Phase 4: Determine Back-up Hardware toSupport Required Uptime Specifications:Right here again the system supervisor andhardware merchant will have a hand in the decision. Centered on the size ofdisks and the quickness of the backup alternative maximum recuperation timeshould end up being developed.

If there is usually no way to meet required uptimerequirements making use of simple back-up schemes then more esotericarchitectures may be indicated like as multi-channeI tapes, hotstandby directories or actually Oracle Parallel Server. Let?t state we requirea 24X7 uptime necessity with immediate failover ( no recoverytime credited to the mission critical nature of the system.) This type ofspecification would need Oracle Parallel Machine in an automatedfailover setup.
We would also use possibly a dual or triple diskmirror therefore that we could split the reflection to perform backups withoutlosing the security of the mirroring.Allow?s compile what we possess determined therefore much:Hardware: 2 - 4 CPU (at highest quickness Central processing unit wecan afford) with at minimum 1 gigabyte (ideally 2) of shared Memory, atleast 2 drive controllers each with multiple stations, 90 gigabytes ofdisk resource using a three way hand mirror to provide us one 30 gig triplemirrored selection. The systems themselves should possess an internal disksubsystem sufficient to help the operating system and any swap andpaging needs. Techniques must be able to talk about disk sources somust help clustering. High-speed tape backup to minimizemirror-split instances.Software: Oracle Parallel Server, Clustermanagement software, Networking software, Backup software program to supportbackup equipment.Capacity and source planning is certainly not an exactscience. Essentially we are usually shooting for a moving target.
