When node detects and when operational module detects that node management table exists in operational order required node, directly this equipment control table node operated according to described bookkeeping order, such as being carried out to replace, this node operates.There is required node in the operational order that server A issues owing to being exclusively used in the node management table of this device management server A, therefore can this node of direct control, and do not need to load the device management tree in DM client.
When node detects and operational module does not detect while there is in bookkeeping order required node in node management table, loading equipemtn management tree, and operate setting upper node according to described bookkeeping order.
Under equipment control DM client multiserver of the present invention, the management method of device management tree, based on said apparatus, comprises the following steps:
DM client be each device management server set up one with the unique corresponding node management table of its server ID, for depositing the dynamic node that creates and manage by device management server;
In the time that DM client is received the bookkeeping order that device management server issues, according to the server ID containing in described bookkeeping order, extract the node management table mating with it;
Then DM client, by whether there being the detection of required node in bookkeeping order in the node management table to extracted, operates node on tree to equipment control table node direct control or after loading equipemtn management tree.
When DM client is by detecting, while finding that the node management table that extracts exists in operational order required node, directly this node is operated according to described bookkeeping order.
When DM client is by detecting, while finding not have in the node management table that extracts in operational order required node, load the device management tree of DM client computer, and operate setting upper node according to described operational order.
DM client, conventionally by setting up DM session with device management server, receives the bookkeeping order issuing from device management server, then detects the node management table mating with the server ID containing in bookkeeping order.The bookkeeping order that device management server issues at least comprises server ID, required node identification and operational order field.
In the time that DM client detects the node management table mating with the server ID containing in bookkeeping order, load detected node management table; In the time that DM client does not detect the node management table mating with the server ID containing in bookkeeping order, create the node management table corresponding with this server ID according to described server ID, then load this node management table.
When the bookkeeping order receiving is while being the interpolation Add order for adding a privately owned dynamic node, DM client by described Add order about the field of privately owned dynamic node is saved in node management table.
In the time that the bookkeeping order receiving is administration order, DM client is searched the node with the required node matching of bookkeeping order in node management table, if existed, directly this node is operated, if there is no, loading equipemtn management tree, then at the enterprising line operate of device management tree.
Fig. 2 has shown handling process when device management server issues bookkeeping order in the present invention, and idiographic flow is as follows:
Step 101: terminal and device management server SeverA set up DM session, the mode of initiating DM session can be that user initiates, DM management server is initiated or other events of terminal are initiated;
Step 102: terminal receives the bookkeeping order issuing from device management server SeverA;
Step 103: terminal is according to the SeverId of device management server SeverA, load the node management table matching with SeverA, if there is no the node management table corresponding with this device management server, creates according to its SeverId that (node management table can have multiple preserving type in terminal: mode by configuration file dynamic load, adopt static structure data mode etc.Taking configuration file preserving type as example, main flow process is: create a node management table according to the severId of server, this tableau format wouldn't be determined; Association attributes in initial table, attribute at least should comprise: the attribute (intermediate node, word etc.) of permanent node or dynamic node, title, size, node path, node content etc.; When completing after the operational order execution of node, preserve this node management table in configuration file).
Above-mentioned steps 103 is to find out unique node management table matching according to the SeverId of device management server from terminal, if the current table of correspondence with it that do not exist of terminal, need first to create, later all privately owned dynamic nodes relevant to this device management server all directly operate on this node management table.
Step 104: if the operational order that SeverA issues is add order, directly in node management table, create corresponding node and other attributes corresponding to node, and register (such as Add order meeting creates a node in node management table, and all properties of this node being saved in table together) such as other information;
Step 105: if the operational order that SeverA issues is the administration order (such as orders such as Copy, Delete, Get, Replace, Exec) except Add order, first in node management table, search the node matching, if existed, directly this node is operated to (such as carrying out the operations such as Copy, Delete, Get, Replace, Exec) according to administration order, if there is not this node in node management table, loading equipemtn management tree carries out corresponding operating according to administration order on device management tree.For convenience of explanation, bookkeeping order is divided into above-mentioned interpolation Add order and administration order here.
Step 106: if issue multiple operational orders, repeating step 104;
Step 107: complete DM session, preserve node management table.
In sum, the present invention has following characteristics:
For each device management server in DM client, set up one with the unique corresponding node management table of its SeverId, in this equipment control table, only deposit that this device management server creates and the dynamic node of management.When terminal receives the operational order that device management server issues, first take out and the unique node management table mating of this device management server, then detect and in this node management table, whether have node required in operational order, if this node is in table, directly equipment control table is carried out to associative operation (corresponding node in node management table being carried out to the orders such as add, copy, delete, exec), without loading whole device management tree, also judge without the ACL authority to node.If this node in the node management table under this server, does not reload the device management tree of terminal, and the node on tree is operated.
The bookkeeping order issuing on device management server can be divided into two classes:
The first kind is Add (interpolation) order, if the order issuing is that (privately owned dynamic node refers to that those are by the own establishment and management of each device management server to interpolation (Add) privately owned dynamic node, the node that other servers cannot be accessed), directly be kept in node management table, do not need loading equipemtn management tree;
Equations of The Second Kind is administration order, and first DM client inquires about whether there is this privately owned dynamic node in node management table, if existed, directly to this nodal operation, if there is no reloads the device management tree in terminal.
The object that bookkeeping order is divided into two classes is to distinguish Add order and other administration orders, Add order is directly kept at node management table while adding new node, if and other administration orders cannot be found node in node management table, need loading equipemtn management tree.
Although above the present invention is had been described in detail, the invention is not restricted to this, those skilled in the art of the present technique can carry out various amendments according to principle of the present invention.Therefore, all amendments of doing according to the principle of the invention, all should be understood to fall into protection scope of the present invention.
