Description
Technical Field
The present invention relates to the field of data processing technologies, and in particular, to a method, a system, and a storage medium for batch modification of data.
Background
SNMP (simple network management protocol) is a communication protocol for a network management server to perform remote management maintenance on a network device, and is used to acquire and configure the operating states and parameters of an operating system, a hardware module, and service software in the network device, and the protocol uses OID (Object ID, object identifier, OID is a string of text-form character strings, the form of which is similar to an IP address, and is composed of a plurality of values separated by dot numbers, for example, "1.2.3.4.1" represents the name of the device, "1.2.3.4.2" represents the system time of the device), and defines a key value for the data in array form, and the key is used to locate a certain piece of data in the identification data array.
For example, the system time parameter of the network device is non-array data because the data is only one. The parameters of the network port working rate of the network device are data in an array type, because the device has a plurality of network ports, one key value is needed to identify one network port, the key value can be defined to be equal to 1,2,3. Note, however, that the key values are not regular and continuous, and perhaps only port 1, port 2, port 3, port 5, and no port 4.
On the basis, the SNMP defines two communication data packets, so as to modify and configure the operation parameters of the managed equipment:
and sending a set-request data packet (request modification data packet) to the managed equipment by the network management server, and requesting to modify a certain data parameter of the managed equipment. The request sets a value specifying OID data, and the specified OID and data values are included in a set-request packet. If the specified OID is the array data, the data packet also needs to carry a key value to indicate which one of the array data the target data is. For example, OID is specified as the parameter of the working rate of the network port in the set-request data packet, the value of the parameter of the working rate is 1000 (10/100/1000 represents 10M/100M/1000M working rate respectively), and key is equal to 2; it means that the operation rate of setting portal 2 is 1000M.
And a set-response data packet (response modification data packet) sent by the managed device to the network management server for feeding back the result of the data modification, wherein the modification result comprises the success or failure of the modification. This packet is used to respond to the set-request packet, returning a success in the setting, or returning an error code when the setting fails.
Wherein, each set-request data packet can only modify one of the data arrays; and the key of the operation object and the new value of the input data need to be manually selected for each set-request data packet, so that the manual operation is slow, and errors are easy to occur in a large number of repeated similar operations.
When the values of all data items of a data array (data of an array formula) are set, the data values can be set only one by one through set-request data packets; the time required to complete all the data in the array is proportional to the number of entries in the data array. Taking the parameters of the working rates of the network ports of the switch equipment as an example, the network ports of the switch usually have 48 working rate parameters which correspond to 48 network ports, and if the working rates of the 48 network ports are required to be completely modified to 1000M, 48 times of similar operations are required to be executed; each operation involves selecting the portal to be modified and the input data value 1000 represents a 1000M work rate, which takes a total of minutes and is also prone to errors. As such, it is inefficient to modify the data of the data array on the network management server.
Accordingly, the prior art is yet to be improved and developed.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
As shown in fig. 1, the batch data modification method according to the preferred embodiment of the present invention includes the following steps:
step S10, the network management server sends a data packet requesting to set a plurality of objects to the managed device.
Specifically, the data has a plurality of values due to a plurality of specific objects, which is called array data (i.e. array data in the present invention), for example, the system time of the computer is non-array data, and the operating system in which the computer is running definitely has only one, that is, only one system time object; the size of a computer disk is data in an array form, a computer has a plurality of disk objects, such as a C disk and a D disk, a key value carried in reading the size data of the computer disk indicates which disk needs to be read, an OID corresponding to the size of the disk can only identify data of 'the size of the disk', but cannot identify 'the size of the D disk in the disk', and the OID and the key = D can be pointed to the object 'the size of the D disk in the disk' together.
The network management server is a core component of a computer local area network, a network operating system is operated on the network management server, and the efficiency of the network management server directly influences the efficiency of the whole network. Therefore, a high-end computer or a dedicated server computer is generally used as the network management server. The network management server mainly has the following 4 functions:
(1) The network operating system is operated to control and coordinate the work among the computers in the network, so as to meet the requirements of users to the maximum extent and make response and processing.
(2) Shared resources in a storage and management network, such as databases, files, applications, disk space, printers, plotters, and the like.
(3) The application Server for each workstation is served, for example, by a Client/Server (Client/Server) architecture, so that the web Server not only acts as a web Server, but also acts as an application Server.
(4) Monitor and control network activities, actually manage the network, allocate system resources, learn and adjust system operating states, shut down/start up certain resources, and the like.
The invention predefines a set-mult-request packet (packet requesting to set multiple objects) to modify the data array in bulk based on the communication of this packet. And the request sets the data packets of the plurality of objects as SNMP data packets. SNMP is a simple network management protocol, belongs to an application layer protocol in a TCP/IP five-layer protocol, is used for a protocol of network management, is mainly used for the management of network equipment, is popular among various manufacturers due to the simplicity and reliability of the SNMP protocol, and becomes the most extensive network management protocol at present.
Specifically, the request sets a set-mult-request packet (set-mult-request packet) for requesting modification of the value of one or more specific objects in the data array of the managed device-specified object identifier. The information carried in the set-mult-request packet requesting to set a plurality of objects includes: object identifier (OID, objectID), new value of the modified data, and key value.
Wherein an Object Identifier (OID) is a globally unique value associated with an object to unambiguously identify the object, ensuring that the object is properly located and managed in the communication information processing; generally, OID is the identity card of the object in network communication.
Wherein the key value is used to locate the operated data entry in the identified data array.
In the invention, the information of the OID and the key value together indicate data to be modified, and if a computer supports an SNMP protocol, a network management server needs to carry the OID to indicate that a target is the size of a disk when the size of the D disk in the disk of the computer is to be modified to be 100G, carries the key = D to indicate that an object is the D disk, and carries a new value of 100G (the new value of the data needs to be modified).
For example, the meaning of the information defining the key value is:
a, ", indicates all data entries.
B, "key1-key2", indicates that the key is all data entries in the range of key1 to key2 (including key equal to key1 and key equal to key 2).
C, "key1, key2", indicates that a data entry having a key equal to key1 and a key equal to key2 may be added in plurality, and each key value is separated by a comma.
D, "key1-key2, key3", i.e., the combination of B and C, indicates that the key is all data entries ranging from key1 to key2 (including key equal to key1 and key equal to key 2) and that the key is equal to key 3.
And step S20, the managed device analyzes the information carried in the data packets of the plurality of objects according to the request to obtain the data items needing to be modified, and changes all the data items into new values through one-time modification.
Specifically, after receiving the set-mult-request packet requesting to set a plurality of objects, the managed device analyzes the operated item objects (i.e., some specified data items to be modified) according to the carried key value information, changes all the operation objects into new values at one time, and is fast and more accurate in modification.
Wherein the managed device comprises a switch.
For example, taking the working rate of 48 network ports of a modification switch (a network device for forwarding an electrical signal, which can provide an exclusive electrical signal path for any two network nodes accessing the switch) device as 1000M as an example, only by using a method of modifying data in a data array in batch, selecting operation objects as all network ports, inputting a new data value as 1000 (inputting only once), and sending an SNMP data packet can be modified, and the total time taken is not more than 15 seconds.
And step S30, the managed device feeds back the operation result to the network management server.
Specifically, the managed device sets information carried in data packets of multiple objects according to the request, and returns an operation result to the network management server after the information is modified. Wherein the operation result comprises a modification success and a modification failure; the modification failure is a value that the modified value is incorrect or cannot be supported.
The key value of a modified object in a data array is listed in an SNMP data packet through a network management server, and the SNMP data packet also comprises a new value of data; the managed device can know all the data items to be modified through the SNMP data packet, can select the keys of a plurality of operation objects at one time on the network management server, and only needs to input the new value of the data once, thereby greatly improving the operation efficiency.

Wherein the request sets a data packet of a plurality of objects for requesting to modify the value of one or more specific objects in the data array of the managed device specific object identifier.
The information carried in the data packet requesting to set the plurality of objects includes: an object identifier, a new value for the modified data, and a key value. The key value is used to locate the data entry in the array of identifying data that was operated on.
And the request sets the data packets of the plurality of objects as SNMP data packets.
The operation result comprises a modification success and a modification failure. The modification failure is a value that the modified value is incorrect or cannot be supported.
