Description
Technical field
The present invention relates to database technical field, particularly a kind of Dblink monitoring method and monitoring system.
Background technology
Generally include multiple business application systems in power system, in order to preserve data in each business application system, generally
There is a corresponding database, and due to intercrossing complicated between power business, need frequently to consult data between database, and
Consulting the data of other databases needs to use Dblink, but prior art can not understand Dblink service condition and safety
Property, operate very cumbersome, workload is big.
Explanation of nouns
Dblink (Database Link), the link of database.
JDBC (Java DataBase Connectivity), the connection of java databases is a kind of for performing SQL languages
The Java API of sentence, unified access can be provided for a variety of relational databases, it is by one group of class write with Java language and connects
Mouth composition.JDBC provides a kind of benchmark, can build the instrument and interface of higher level accordingly, enable database development personnel
Write database application.
The content of the invention
, can be in the progress between database it is an object of the invention to provide the monitoring method of Dblink a kind of and monitoring system
During access, Dblink service condition is connected to database（That is the interconnection situation of database）It is monitored with security.
The technical scheme that the present invention takes is：A kind of Dblink monitoring method, including：
S1, driven by JDBC and be connected with Database to be checked；
S2, obtain the Dblink white lists of database to be checked；
S3, by calling JDBC database manipulation interface, Dblink information is obtained, the Dblink got is monitored,
Including：
Judge whether Dblink is contained in the Dblink white lists of S2 acquisitions, if then terminating to monitor, if otherwise will be current
Dblink is arranged to doubtful illegal Dblink, closes the access rights of the Dblink, generates warning information；
S4, alarming processing is carried out, including：For Dblink corresponding to warning information, judge its whether because practical application needs and
Allow to access database to be checked, corresponding Dblink is defined as unauthorized access link, outputting alarm information, prison if not allowing
Control terminates, if allowing, corresponding Dblink is defined as into Lawful access link, and authorizes access rights to the Dblink, will
It adds the Dblink white lists of database to be checked, then goes to step S3 and the Dblink got is monitored again,
Until corresponding Dblink is contained in the Dblink white lists of S2 acquisitions, or corresponding Dblink is defined as unauthorized access
Link, terminate monitoring.
In S1, JDBC drivings include：The driving of JDBC-ODBC bridges, the driving of JDBC- locals, JDBC network-drivens and local association
Discuss pure JDBC drivings.Different JDBC drivings can be used for accessing different databases, and specific access mode can use prior art.
The Dblink obtained in S2 of the present invention is the Dblink white lists of corresponding target database to be checked, and its content can be by
The operation maintenance personnel of associated databases is configured.
Preferably, in S3, by the Statement for calling JDBC（）Interface, instantiation operation database to be checked, and hold
Row executeQuery（）Method, return values of the sql on Dblink is obtained, that is, obtains Dblink information.Statement connects
Mouth is used on the basis of database connection is had built up, and the Simple SQL sentence without parameter to be performed is sent to database.
ExecuteQuery is the method that the one of which that Statement interfaces provide performs SQL sentences, for producing single knot
The sentence of fruit collection, such as SELECT sentences.
Further, S3 also includes：The Dblink blacklists of corresponding different databases to be visited are set, judged doubtful illegal
Whether Dblink is contained in Dblink blacklists, if then terminating to monitor, outputting alarm information, if otherwise going to step S4；
In S4, for considering that practical application needs not allow the Dblink for accessing database to be checked still, by corresponding Dblink
Add blacklist.Identification deterministic process is simplified by blacklist for the illegal Dblink in part, Dblink monitoring can be reduced and accused
Data redundancy during alert processing.
Preferably, in S3 and S4, the Dblink of foundation is monitored at predetermined intervals and alarming processing.
In the S4 of the present invention, whether because practical application needs the judgement that accesses database to be checked is allowed to Dblink,
Judged result is provided by database operation maintenance personnel.
Invention additionally discloses a kind of Dblink monitoring system, including：
Database connection establishment module, driven by JDBC and be connected with Database to be checked, obtain Dblink information；
Database connects white list acquisition module, obtains the Dblink white lists of database to be checked；
Dblink monitoring modules, judge whether currently available Dblink is included in Dblink white lists, if then terminating to monitor,
If current Dblink otherwise is arranged into doubtful illegal Dblink, the access rights of the Dblink are closed, generate warning information；
Warning processing module, for Dblink corresponding to warning information, judge whether it allows to access because practical application needs
Database to be checked, corresponding Dblink being defined as unauthorized access link if not allowing, outputting alarm information, monitoring terminates,
If allowing, corresponding Dblink is defined as Lawful access link, and access rights are authorized to the Dblink, is added into and treats
Inquire about the Dblink white lists of database.
Further, the Dblink blacklists of corresponding different databases to be visited are also preset with Dblink monitoring modules；
After current Dblink is judged as doubtful illegal Dblink, whether Dblink monitoring modules also judge the doubtful illegal Dblink
It is contained in Dblink blacklists, if then terminating to monitor, outputting alarm information, if otherwise by corresponding doubtful illegal Dblink's
Warning information is transmitted to warning processing module；
Warning processing module will consider that practical application needs not allow the Dblink for accessing database to be checked still, add black name
It is single.Identification deterministic process is simplified by blacklist for the illegal Dblink in part, when can reduce Dblink monitoring and alarming processing
Data redundancy.
Beneficial effect
The present invention is driven by JDBC and is connected with Database to be checked, and then JDBC interfaces corresponding to calling obtain Dblink
Information, the Dblink white lists based on database to be checked, is monitored to the Dblink of database to be checked so that work people
Member easily can be monitored to each data in power system, obtain the service condition linked in each database, ensure
The data safety of target database, meanwhile, the professional ability requirement to operation maintenance personnel substantially reduces, and can also reduce manual operation
Loss caused by error.
