Referring to FIG. 2, Fig. 2 is the flow diagram for connecting method for building up in another embodiment of the application, the connection is built
Cube method can be used in server, comprising the following steps:
Step 201, the time for beginning setting up connection is calculated according to the grouping where this equipment.
In the present embodiment, the grouping where described equipment can be configured in advance by administrative staff, can also be by
Management server in service server cluster distributes group number according to preset strategy for each service server, and the application is to this
It is not particularly limited.
By taking administrative staff are the service server setting grouping in service server cluster in advance as an example, it is assumed that business service
There are 1000 service servers in device cluster, then the service server in the service server cluster can be divided by administrative staff
5 are grouped, and include 200 service servers in each grouping.Certainly, administrative staff can also be by the service server cluster
In service server be divided into 10 groupings, then include 100 service servers in each grouping.Administrative staff are setting
After grouping, the group number being grouped where it is issued for service server preservation for every service server.The group number of the grouping
The sequence of connection can be used to indicate to establish with Database Systems, such as: the service server in the smallest grouping of group number is at first
Connection is established with Database Systems, the service server time in the small grouping of group number first establishes connection, group with Database Systems
Service server in number maximum grouping finally establishes connection with Database Systems.The group number of the grouping can since 1,
It can also be since other numerical value.Preferably, it can set the group number of the grouping to since 0, to facilitate server root
The time for beginning setting up connection is calculated according to the group number being grouped where this equipment.
It in this step, can be time-consuming to obtain this equipment multiplied by preset connection with the group number of the grouping where this equipment
Begin setting up the time of connection.Wherein, the preset connection is time-consuming is usually taken by administrative staff according to business in each grouping
Being engaged in, the connection consumed time determines in batches for device foundation.It is assumed that Database Systems are arrived in service server foundation in each grouping
Time consumed by batch connection is 10ms-50ms, then can set any number in 10ms-50ms for the connection time-consuming
Value.
As an example it is assumed that it is 10ms that the preset connection is time-consuming, administrative staff will be in certain service server cluster
Service server is divided into 5 groupings, be respectively as follows: grouping 0, grouping 1 ..., grouping 4.If the industry in the service server cluster
The group number of grouping where business server 1 is 0, then the service server 1 is time-consuming multiplied by the connection with its group number, i.e., 0 ×
10ms, the obtained time for beginning setting up connection are 0ms.If where the service server 2 in the service server cluster

Time before, which receives the service request for needing to access Database Systems, at this time in the service server
There is not yet the connection to the Database Systems, in order to handle the service request, the service server is to Database Systems
A connection request is sent, to establish a connection to the Database Systems, and based on the connection and the data base set
System is communicated to handle the service request.
As an example it is assumed that the time for beginning setting up connection of service server 2 be 30ms, then if reach 30ms it
Before, such as: service server 2 receives the service request 1 for needing to access Database Systems when 10ms, due to
There is not yet the connection to the Database Systems when 10ms in service server 2, then service server 2 sends 1 company
Request is connect to Database Systems, 1 is established with the Database Systems and connect to handle the service request 1.
Further, it needs to access data base set if the service server 2 receives one when 20ms again
The service request 2 of system has existed 1 connection for arriving Database Systems at this time, then judges that the connection is current in service server 2
Whether can be used, if the connection is currently available, using the connection to handle the service request 2, if the connection currently can not
With, such as: the connection is used by the service request 1 that 10ms is received, then service server 2 sends 1 connection again and asks
Database Systems are sought, another 1 is established with the Database Systems and connect to handle the service request 2.
Step 203, when beginning setting up the time of connection described in the arrival, judge that this current equipment arrives the Database Systems
The quantity M of connection whether be less than connection lower limit value.If the quantity M of connection of this current equipment to the Database Systems is small

With the difference of M.
It is small in the quantity M of connection of this current equipment to the Database Systems based on the judging result of abovementioned steps 203
When the connection lower limit value, Xiang Suoshu Database Systems send connection request, to continue to establish the connection with Database Systems.
Specifically, in this step, N number of connection request is sent to Database Systems, wherein N can be the connection upper limit value and M
Difference, N may be it is described connection lower limit value and M difference, can be specifically configured by developer, the application to this not
Make specifically limited.
As an example it is assumed that the connection upper limit value of certain service server is 10, connection lower limit value is 3, if currently originally set
The quantity M of the standby connection to the Database Systems is 2, then in this step, can send 8 or 1 to Database Systems
Connection request.
Step 205, N number of connection request is sent to Database Systems, N is the difference of the connection upper limit value and M.
It is big in the quantity M of connection of this current equipment to the Database Systems based on the judging result of abovementioned steps 203
It when the connection lower limit value, can continue to send connection request to the Database Systems, to continue foundation and database
The connection of system.Specifically, in this step, N number of connection request is sent to Database Systems, wherein N is the connection upper limit
The difference of value and M.
Still with the connection upper limit value of certain service server for 10, for connection lower limit value is 3, if this current equipment arrives institute
The quantity M for stating the connection of Database Systems is 6, then in this step, can send 4 connection requests to Database Systems.
