Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Fig. 1 is the auxiliary design method process flow diagram for shared data protection of the present invention.As shown in Figure 1, described method comprises:
Steps A: according to the kernel feature of each operating system, sets up rule feature table and the attributive character table of corresponding each operating system.For the sake of simplicity, the present embodiment illustrates the inventive method for the (SuSE) Linux OS that kernel version is 2.6.The rule feature table of following table 1 to be corresponding kernel version the be (SuSE) Linux OS of 2.6, as shown in table 1, in described rule feature table, rule feature numbering corresponding to data, rule feature key word, rule feature description and protection mechanism shared in record.The attributive character table of following table 2 to be corresponding kernel versions the be (SuSE) Linux OS of 2.6, as shown in table 2, attributive character numbering, attributive character key word and attributive character that in described attributive character table, record shares data corresponding describe.
The corresponding kernel version of table 1 is the rule feature table of the (SuSE) Linux OS of 2.6
The corresponding kernel version of table 2 is the attributive character table of the (SuSE) Linux OS of 2.6
Step B: according to the current operation system title of user's input, select corresponding current rule feature table and current attribute mark sheet.
Step C: according to the first instruction of user's input, from current rule feature table, extracts the current protection mechanism that current shared data are corresponding.
Described step C specifically comprises step:
Step C1: according to the first instruction of user's input, the rule feature selecting current shared data corresponding from current rule feature table.Particularly, the rule feature of current rule feature table is presented to user and is selected by computing machine successively, and user chooses a corresponding rule feature according to the service condition of current shared data; If do not have suitable rule feature, user does not choose any rule feature.
