Table 6

Prediction model generating apparatus 105 is used for generating the prediction model that comprises transaction rate and CPU time linear relationship and period transaction accounting according to transaction channel classification map relation and transaction channel period mapping relations.Accomplish input, calculating, preservation, the transmission of host parameter; Prediction model generating apparatus 105 is accomplished the statistics of Transaction Information according to estimating demand; Statistics is analyzed, set up prediction model, prediction model is partly formed by two; A part of delineation divides the linear relationship between channel transaction rate and the CPU TIME, as:

y ₁＝a ₁x ₁+b ₁；

y ₂＝a ₂x ₂+b ₂；

y _k＝a _kx _k+b _k；

Here k representes the channel species number, and as far as channel arbitrarily, CPU self has a consumption the most basic when transactional services is provided, represent with b at this, and the scale-up factor between transaction rate and the CPU TIME is then represented with a.

More than trading volume (x in the corresponding one type of channel of each linear equation _i) consume CPUTIME summation (y with these exchanges _i) between relation.Another of model partly delineated the proportioning situation of each transaction period, for example, whole day is divided into j time period, then the K class channel of each time period conclude the business proportioning just can be with regard to following matrix representation, as:

$A=\begin{array}{cccc}{\mathrm{\ζ}}_{11}& {\mathrm{\ζ}}_{12}& ...& {\mathrm{\ζ}}_{1k}\\ {\mathrm{\ζ}}_{21}& {\mathrm{\ζ}}_{22}& ...& {\mathrm{\ζ}}_{2k}\\ ...& ...& ...& ...\\ {\mathrm{\ζ}}_{j1}& {\mathrm{\ζ}}_{j2}& ...& {\mathrm{\ζ}}_{\mathrm{jk}}\end{array}$

Above-mentioned matrix A is expressed as the accounting relation of k class channel at each period j (value is 00:00-24:00 hour), i.e. ζ _IlValue represent l class channel transaction in the constantly shared ratio of i.

Wherein, each the row all elements sum in the matrix is 1, is illustrated in section sometime, and transaction is made up of the transaction of this K class channel.

Prediction model has been arranged, the given transaction peak period time period, promptly can estimate out:

1. under specific transaction rate, the utilization rate situation of online CPU;

2. under specific online CPU, the transaction rate situation that can support;

After setting up prediction model, obtaining estimation results, 106 pairs of prediction models of result data tabulation output unit are estimated; If deviation surpasses the scope that allows acceptance, then select for use different Transaction Informations to estimate again, iterate (for preventing overfitting; Regulation is no more than the iterations restriction), correction result is in the hope of getting prediction model to the end; After write the prediction model storehouse, and produce output result.

Result data tabulation output unit 106, main prediction model to estimating is chosen Transaction Information and estimation results is compared, and sees that error is whether within tolerance interval; If, then can generate estimation results by new prediction model, otherwise, again from choosing Transaction Information; Carry out statistical study, produce new prediction model (prediction model after promptly correcting) once more, submit to the prediction model evaluation module to estimate; By that analogy, carry out iteration, in certain iterations scope; Produce new prediction model, after its estimation results satisfies the error limitation condition, the output estimation results.

Result data tabulation output unit 106 generates the results list of following two kinds of forms according to prediction model.

1. give an example to the estimation results of cpu busy percentage by the transaction rate: (like table 7)

Table 7

When 2. reaching concern value and warning value by online CPU, the transaction rate that can support for example.(like table 8)

Table 8

The processing of channel variable parameter contains reception, preservation, merging and the fractionation of variable, divides into groups all transaction by channel here, and be the needs of application facet on the one hand; On the other hand; For the accuracy that guarantees to estimate, can two or more channels be merged into a channel, as long as its transaction attribute of the channel that merges has the consumption basically identical of general character-CPU; And it is comparatively constant; When the transaction in the channel does not have this general character, just need split, to satisfy above-mentioned requirements.

In reception, the preservation of time parameter were handled, time parameter can have multiple granularity: 1 minute, 15 minutes, 1 hour, day, month, year.

In the statistic of classification information of transaction, type is whole channel variable noted earlier, and the time granularity of statistics is the time granularity described in the module 302.

When putting preset time, the accounting situation of all channel transaction, this accounting are the formation of some transaction preset time; To estimating important influence; Rush hour section, different festivals or holidays, the formation of transaction is mutually different, and the CPU of its consumption is also correspondingly different.

As shown in Figure 3, the workflow of the mainframe CPU capacity predict system of present embodiment is following:

Step S201: capacity is estimated application: because the various variations that take place on the structure are formed in the transaction that all previous application version brings; And the transaction rate that market fluctuation brought growth, brought bigger variation to capacity requirement, particular times such as particularly annual National Day, New Year's Day, the Spring Festival; The transaction rate can significantly increase; But the channel and the application type that cause the transaction rate to increase are not growth in proportion, but due to being increased substantially by wherein a few types, and to estimate demand comparatively frequent for capacity for this reason.

Estimate input or the reception of application demand through precompensation parameter, the date type (during arm's length transaction day, phase brisk in the market, National Day, during New Year's Day, during the Spring Festival) estimated, timing node (morning peak period, afternoon peak period) need be provided.

Step S202: by being applied for: input parameter is carried out consistency check, and precompensation parameter is carried out logical process judge, calculate the Transaction Information of the statistical study situation that needs.

Step S203: Transaction Information is carried out statistical study by statistical demand, generate two types of mapping relations at least, one type for to press the multivariable statistical information of channel, and the result is as shown in table 9 for example:

Table 9

The statistics here can be the statistical information by various time granularities noted earlier.

Another kind of result is the proportioning situation of a certain moment transaction, and proportioning result is as shown in table 10 for example:

Table 10

Step S204: from the above-mentioned statistical information that obtains, accomplish the capacity of host CPU and estimate, form necessary prediction model.

Step S205: the prediction model result who obtains is preserved, supply in the follow-up middle use of calling, follow-up calling mainly comprises two aspects:

Be the adjustment of model on the one hand, in the process of self study, constantly produce new prediction model, constantly revise the preservation of intermediate result;

Be on the other hand when last estimation results produces, call up-to-date prediction model, generate the estimation results tabulation.

Step S206: the prediction model to producing is estimated, and mainly generates the estimation results tabulation with up-to-date prediction model, with partial data in the tabulation and actual the comparing of production; The production real data is here calculated the error that exists between the two from the data in the Transaction Information, and whether comparison result satisfies error requirements; If; Then generate the estimation results tabulation, otherwise, Transaction Information added up again; Repeat the step between the S202 to S205, till producing comparatively satisfied prediction model or iterations and reaching certain restriction.

Step S207: the prediction model that S205 produced set by step generates the estimation results tabulation disaggregatedly.
