Process status table has kept the operating state, version number, message queue of process to overstock process relevant informations such as situation, by process status Version Control assembly, regularly and by the mode of message trigger upgrades and safeguards that its data structure has the C language representation as follows:
The structure information storage PNOInfo of each Business Processing process
typedef?struct
{
Unsigned long long PNO:14; Process of unique identification in the // framework
Unsigned long long State:4; // process status
Unsigned long long QueueNum:14; The load of // message queue
Unsigned long long PID:32; The operating system process number that //OS distributes
}PNOInfo；
The storage organization SvrGroup of the business process of each type of service
typedef?struct
{

The business process control assembly of framework comes the version of differentiated service function treatment process by the version number information of filename name suffix.
The naming rule of business process version number:
＜business procedure name〉＜_＜a.b.c.d 〉
Example: OCS_1.0.0.106
Wherein a, b, c, d represent four parts of the version number of business application respectively, each part period (.).First underscore (_) that runs into forward at last from whole filename is as the decollator of business procedure name and version number.
The span of a, b, c, d is 0～255 (8), forms 32 bit data according to order from high to low, is kept in 32 the data field, and corresponding data structure is as follows with the C language representation;
The storage organization ProgVersion of business process version
typedef?struct
{
UINT8 ProgMame[128]; // business process filename
UINT32 VersionID; // business process target version this shop
}ProgVersion；
Three, the control of the multi-course concurrency of high efficiency process status table visit
In the process status table, the process status information of preservation is to carry out reference data important in the forwards processing procedure, relates to a plurality of processes or concurrent visit, and under situation about guaranteeing data security, we have used atomic operation to guarantee treatment effeciency.
