Description
Technical Field
The invention relates to the technical field of server BMC configuration, in particular to a method and a system for customizing a character library of BMC configuration parameters.
Background
In order to realize the powerful server monitoring and management functions of the BMC, a whole set of support for configuration parameters of different functions and different applications is required, such as a group name, an engini id, a system name, an authentication password, an encryption password and the like for supporting a snmp function, a user name, a password, a user group, kcs, sol and other related parameters for supporting an IPMI protocol, an encryption algorithm for supporting security enhancement and the like. When a user configures the parameters, the support conditions of the configuration parameters for the characters input by the user are different, some support only upper and lower case letters and numbers, and some support need to support some special characters or all special characters, so when the user configures the parameters, different character libraries need to be called according to certain rules to determine the characters input by the user, and currently common determination methods include the following steps:
1. when a character library calling request exists in a certain parameter, a character library specially aiming at the character is temporarily established aiming at the parameter, and character judgment is carried out according to the character library. And when the input accords with the characters in the current character library, judging that the input of the configuration parameters is legal, otherwise, judging that the input of the configuration parameters is illegal, and prompting the user to input errors and input again. The method is relatively flexible, and can meet different judgment requirements on characters under various conditions, but the method has the following defects:
(1) cannot be flexibly configured according to customer requirements. The finally compiled and generated image file is determined for the character library called by any configuration parameter, and when a field client needs to adjust the characters in the character library aiming at a certain parameter according to the self requirement, the field client looks catch the elbow;
(2) multiple definitions, character library and decision rule adjustment and correction become complicated. Under the condition that webui exists or the code architecture level is relatively complex, the character library and the judgment rule aiming at the same configuration parameter may need to be defined for many times, so that when the character library aiming at the current configuration parameter needs to be adjusted, the condition of modification omission exists, the stability of the code is reduced, and the maintainability is reduced;
(3) the character libraries are various and cannot form a unified rule and character library table which can be integrally managed.
2. A complete character library calling library is formed in a BMC in a dynamic link library mode, and a certain configuration parameter corresponds to one character library in the link library.
In consideration of the defects existing in the calling scheme of different configuration parameters aiming at the character library in the BMC, the method for realizing dynamic customization of different configuration parameters of the BMC aiming at the character library is provided.

Specifically, the method for customizing the character library of the BMC configuration parameters includes:
(1) as shown in fig. 2, characters are classified into four categories, i.e., capital letters, lowercase letters, numerals, and special characters, in which upper and lower case letters and numerals represent one category only after storing in ASCII code of the first letter or the first numeral, for example, capital letters, only one byte space is opened in storage and storing 'a' represents capital letters, and lowercase letters store 'a' in storage, and numerals represent "0" in storage. The special characters are represented by separately opening up space by using the corresponding ascii codes.
Each character is followed by a two-byte character scheme group flag field, in addition to storing its own ASCII code, the character scheme group flag field of each character indicates the use of the current character in scheme group 0-scheme group 15 by bit, 1 indicates use, and 0 indicates no use. The character scheme group is a commonly used character library scheme group formed by designing and planning a storage structure of a character library and character libraries adopted by different configuration parameters of the BMC, 16 sets of character scheme groups are designed in the embodiment, and each character scheme group corresponds to a commonly used parameter value of the BMC. Different configuration parameters can flexibly select any one of the character scheme groups as a character library of the user, and the default character scheme group can be reconstructed and configured according to the requirements of the user without modifying codes to regenerate the image file.
In order to ensure the safety of character storage, the application stores all character data into EEprom (electrically erasable programmable read only memory).
(2) Each character is followed by a two-byte character scheme group flag field, in addition to storing its own ASCII code, the character scheme group flag field of each character indicates the use of the current character in scheme group 0-scheme group 15 by bit, 1 indicates use, and 0 indicates no use.
Thus, the construction of the character storage architecture is completed. In EEprom, upper and lower case letters, numbers and a map of each special character and the use of each character in a case group 0 to a case group 15 are stored, and 16 case groups that can be selected and flexibly configured are formed for all characters.
(3) The method comprises the following steps that the serial numbers of character scheme groups selected by different configuration parameters are stored next to the character scheme group, each configuration parameter occupies one byte, if the configuration parameter is 0, the character scheme group of the scheme group 0 is selected, if the configuration parameter is 1, the character scheme group of the scheme group 1 is selected, and the specific required byte number can be flexibly expanded according to the number of the configuration parameters.
(4) Aiming at the character scheme group, a user can modify the default initial value according to the requirement of the user, and aiming at different configuration parameters, the corresponding character scheme group can be appointed through a command, and the corresponding character scheme group can also be searched through a mapping relation. And then screening out the characters marked with the character scheme group as a formulated character library of the configuration parameters. Therefore, the method for dynamically customizing the character library under different configuration parameters and different customer requirement modes is met.
