In some embodiments of the invention, can select as required different grouping strategies to come resource and kernel are divided into groups, the grouping strategy under the different scenes may be not quite similar.

For example, the grouping strategy of resource can comprise following tactful a1, strategy a2, strategy a3, the combination of one or more among strategy a4 and the tactful a5: a1, the resource division that type of service is identical (is appreciated that in same resource group as far as possible, type of service may be relative concept, for example type of service can comprise talk business and flow business, wherein, it is professional that talk business can be divided into again fixed telephone service and mobile call, the mobile call business can be divided into again the roaming talk business and local call is professional, wherein, the roaming talk business can be divided into again inter-provincial roaming talk business and international roaming talk business etc., and other situation by that analogy); A2, strongly connected resource in the same operation flow can be divided into a resource group as far as possible; The hot point resource of a3, business association is divided into different resource groups as far as possible; A4, certain resource that data volume is larger can be processed according to the subregion of table, split into a plurality of resource groups.Can delete old resource group or projected resources group etc. again when a5, business reorganization.

Again for instance, the grouping strategy of kernel can comprise one or more the combination among following tactful b1, tactful b2 and the tactful b3: b1, core group and resource group can be one to one relation.The size of b2, core group is adapted to have with this core group the resource group of mapping relations as far as possible, for example for the upper strata key business resource group higher to performance requirement, and the relatively many core group of check figure in as far as possible shining upon with it.When b3, the professional variation, capable of dynamic is adjusted the interior check figure (for instance, increasing or reject the kernel of corresponding core group) of corresponding core group, and for example telecom charging is professional, and conversation increases sharply in the stage in the Spring Festival, can increase the interior check figure of corresponding core group in this time period.

In some embodiments of the invention, first resource group, Secondary resource group, information resources group or the 4th resource group can comprise the subregion of at least one table and/or at least one table.

In some embodiments of the invention, type of service corresponding to all resources in first resource group, Secondary resource group, information resources group or the 4th resource group is identical.

In some embodiments of the invention, all resources in first resource group, Secondary resource group, information resources group or the 4th resource group are the resource that is associated in the same operation flow.

Can find out, the present embodiment is after receiving the first resource request of access; Call the kernel processes first resource in the first core group, wherein, first resource belongs to the first resource group, first resource is the resource of first resource request of access institute request access, the first core group comprises at least one kernel, wherein, have mapping relations between first resource group and the first core group.Because resource and kernel are divided into groups, and the mapping relations of resource group and core group have been set up, certain core group mainly special disposal has with it resource in the resource group of mapping relations, therefore is conducive to improve the hit rate of resource, and then is conducive to improving performance.

Further, because resource is also carried out grouping management, therefore, can as required grouping be distinguished in key business and resource corresponding to general service, resource group corresponding to key business can be shone upon with the stronger core group of processing power, be conducive to so more reasonably distribute and manage kernel, and then be conducive to promote the coordinating and unifying of hardware layer management, be conducive to effectively improve the key business performance, also be conducive to not take full advantage of the multi-core technology of current popular, improve concurrency, for example be conducive to utilize more fully the parallel architectural frameworks such as non-homogeneous memory access model (NUMA, Non-Uniform Memory Access).

Further, group-based administrative mechanism, the possibility so that the database perception service becomes.When larger traffic pressure, capable of dynamic is adjusted interior check figure in the core group of traffic aided or the mapping relations of adjustresources group and core group, and the performance that as far as possible guarantees key business can fast reducing, so, can be so that Database Systems adaptability be stronger, the service optimization ability is stronger.

For ease of better understanding and implement the such scheme of the embodiment of the invention, the below is some above-described embodiment schemes application scenarios that may relate to for example, such as the scene of the application scenarios of dividing the resource group, the application scenarios of dividing core group, mapping resource group and core group etc.

See also Fig. 2, Fig. 2 shows a kind of resource access method that another embodiment of the present invention provides, and can comprise following content:

201, be a plurality of resource groups based on predetermined resource grouping strategy with resource division;

For example, the grouping strategy of resource can comprise that one or more the combination among following tactful a1, tactful a2, tactful a3, tactful a4 and the tactful a5: a1, as far as possible that type of service is identical resource division are in same resource group; A2, strongly connected resource in the same operation flow can be divided into a resource group as far as possible; The hot point resource of a3, business association is divided into different resource groups as far as possible; A4, certain resource that data volume is larger can be processed according to the subregion of table, split into a plurality of resource groups.Can delete old resource group or projected resources group etc. again when a5, business reorganization.

In some embodiments of the invention, the elementary cell of the resource in the resource group can be table, table subregion etc.Wherein, each resource group can visit resource in the resource group according to resource group sign to unique resource group sign should be arranged.

For example referring to shown in Fig. 3-a, suppose to exist traffic table 1, traffic table 2 and traffic table 3, wherein, the correlation comparison of traffic table 1 and traffic table 2 is strong, therefore traffic table 1 and traffic table 2 can be divided into 1 resource group (resource group s1), the data volume that traffic table 3 comprises is larger, higher to performance requirement, some field that can service based table 3 is divided into a plurality of table subregions (Fig. 3-a is to be divided into traffic table 3 two table subregions as example) with traffic table 3, each table subregion of traffic table 3 is divided into respectively different resource groups, wherein, Fig. 3-a table subregion a1 that example illustrates traffic table 3 that passes the imperial examinations at the provincial level is divided into resource group s2, and the table subregion a2 of traffic table 3 is divided into resource group s3.

202, based on predetermined kernel grouping strategy kernel is divided into a plurality of core group;

For instance, the grouping strategy of kernel can comprise one or more the combination among following tactful b1, tactful b2 and the tactful b3: b1, core group and resource group can be one to one relation.The size of b2, core group is adapted to have with this core group the resource group of mapping relations as far as possible, for example for the upper strata key business resource group higher to performance requirement, and the relatively many core group of check figure in as far as possible shining upon with it.When b3, the professional variation, capable of dynamic is adjusted the interior check figure (for example, increasing or reject the kernel of corresponding core group) of corresponding core group, and for example telecom charging is professional, and conversation increases sharply in the stage in the Spring Festival, can increase the interior check figure of corresponding core group in this time period.

In some embodiments of the invention, can or check that by system call system file obtains the kernel topology situation of CPU, and predetermined kernel grouping strategy logically is divided into different core group, owing to be the logical partitioning core group, so can not affect existing framework.Number of cores in the dynamically adjustment group of each core group.For example, for the important service hot spot data, can increase interior check figure guarantee the respective resources group the service process performance of corresponding core group.For the less data of some portfolio, can reduce in right amount the interior check figure of its corresponding core group, in order to take full advantage of hardware resource.

Wherein, core group also can be referred to as virtual box (VCR, Virtual Core Rack).

For example shown in Fig. 3-b, suppose to exist kernel 1～8, kernel 1～4 can be divided into core group c1, kernel 5～6 is divided into core group c2, kernel 7～8 is divided into core group c3.

203, set up the mapping relations of resource group and core group.
