具体实施方式 detailed description

[0026]下面结合具体实施例对本发明作进一步说明。 [0026] The following embodiments in conjunction with specific embodiments of the present invention will be further described.

[0027]本发明的提供一种基于oracle数据库备份及恢复的方法,特别是.net技术框架体系下,通过应用程序客户端操作应用服务器实现数据库服务器中oracle库的备份与还原的方法。 The invention provides a [0027] method of the present oracle database backup and recovery based, in particular in the framework .net technology, the database backup and restore method oracle server database implemented by a client application program operating an application server. 如附图1所示,其具体实现过程为: As shown in Figure 1, the specific implementation process is as follows:

[0028] S10:初始化并启动执行步骤; [0028] S10: initializes and starts executing step;

[0029] S11:备份文件以及备份文件的校验文件的导出; [0029] S11: the backup file and the backup file exported file checksum;

[0030] S12:备份文件以及备份文件的校验文件的导入及校验; [0030] S12: import the backup file and the backup file and the checksum of the file;

[0031] S13:对备份文件的导入。 [0031] S13: Import of backup files.

[0032] 在步骤S10中,初始化以下步骤: [0032] In step S10, the initialization steps of:

[0033] 1)在连接数据导出数据库服务器的应用服务器上安装与oracle服务端相匹配的oracle客户端; Installation and service end matching oracle oracle client application on the server [0033] 1) derived in the database server connection data;

[0034] 2)在连接数据导入数据库服务器的应用服务器上安装与oracle服务器端相匹配的oracle客户端; [0034] 2) Installation and oracle oracle server end matching client into the database server, an application server in the connection data;

[0035] 3)源端对应的应用服务器中部署计划任务。 Application Server [0035] 3) corresponding to the source deployment plan task. 该计划任务作用,备份源数据库,并加密压缩; The action plan task, the source database backup, encryption and compression;

[0036] 4)目标端对应的应用服务器中部署计划任务。 Application Server [0036] 4) corresponding to the target-side deployment plan task. 该计划任务作用,调度应用服务器上独立部署的应用程序。 The role of scheduled tasks, scheduling applications on the application server for standalone deployment.

[0037] 所述初始化步骤中,源端的应用服务器上的计划任务方式包括:对源数据库定期备份、加密压缩到指定目录、删除7天之前的备份文件压缩包;目标端应用服务器上的计划任务方式包括:调度指定应用程序轮询导库指令。 [0037] The initialization step, scheduled tasks embodiment the source application server comprising: a source database regular backups, encrypted and compressed to the specified directory, delete the backup file 7 days prior to the compressed packet; scheduled tasks on the target end of the application server include: polling schedule specifies the application library instruction guide.

[0038] 在步骤SI 1中,通过源端的应用程序客户端,下载数据库备份文件,并生成备份文件校验文件。 [0038] In step SI 1, by the client application source terminal, download the database backup file, backup file is generated and the verification document.

[0039]备份文件以及备份文件的校验文件的导出。 [0039] Export backup files and check files backup files. 进一步说明,客户端备份文件的导出, 是采用“下载”的方式。 Further instructions to export the client backup file is to use the "Download" approach. 这里的下载不同于.net技术体系下一般的下载。 .net downloaded here is different from the general technical system downloads. 考虑到备份文件的文件访问权限控制,该文件保存目录没有配置成为虚拟目录,发布URL地址的方式,提供下载。 Taking into account the backup file access control, save the file directory mode is not configured to be a virtual directory, publishing URL addresses, available for download. 而是采用,文件保存目录指定权限任何人不能访问,然后通过应用程序读取文件的方式,形成流,在客户端写文件。 Instead of using, specify the directory to save the file permissions anyone can access, how the file is then read by the application form stream, writing in the client file. 考虑到备份文件的规模以及可用性,5G以下文件提供下载,并且支持断点续传。 Given the size and the availability of backup files, 5G following file available for download, and support for HTTP. 文件下载到客户端以后,生成该文件的校验文件。 After the file is downloaded to the client, to generate the file checksum file.

[0040] 在步骤S12中,通过目标端的应用程序客户端,上传数据库备份文件,并依据源端导出备份文件校验文件,对上传的备份文件进行校验。 [0040] In the step S12, by application clients on the target side, the database backup files to upload, and export a backup file checksum files based on the source of backup files uploaded for verification. 防止在文件导出,导入的中间环节, 文件被篡改。 Prevent file export, import of intermediate links, files were tampered with.

[0041] 进一步说明。 [0041] further explanation. 技术角度,防止备份文件的导入与导出环节被篡改,是通过校验文件来实现的。 Technically, to prevent the backup file import and export part has been tampered with, by checking the file is achieved. 导出环节,下载备份文件到客户端,并生成该文件的校验文件。 Export links, download a backup file to the client, and generate file checksum of the file. 导入环节,是通过特定规则校验该备份文件以及校验文件是否匹配。 Import link is checking whether the backup file and check the file by matching specific rules. 信息匹配则允许导入。 It is allowed to import information matches. 文件的导入,也是基于文件流的读写,支持5G以内文件大小的断点续传。 Import file, the file is read based on the flow, within 5G support HTTP file size.

[0042] 在步骤S13中,通过目标端的应用程序客户端操作,对S12上传到应用服务器端的备份文件解压,清空镜像库数据对象,导入。 [0042] In step S13, the client application operating on the target side, of S12 to upload a file backup application server decompressed image library empty data objects, import.

[0043] 进一步说明。 [0043] further explanation. 出于安全保密角度,备份文件的解压也是在应用服务器上。 For security and confidentiality point of view, extract the backup file is in use on the server. 目标端的应用服务器中,实现备份文件的解压,备份文件恢复成镜像库。 End of the target application server, the realization of extracting backup file and restore backup files to the image library. 这里客户端机器控制应用服务器中的应用软件,.net技术框架下,需要开放应用服务器下IIS的一些权限。 Here the client machine control application server application software, .net technical framework needed to open up some authority under the IIS application server. 出于应用服务器安全性的考虑,采用客户端生成加密后的操作命令,应用服务端计划任务方式调度一个独立的应用程序解密指令,根据指令类型,调度相应的exe,从而实现备份文件加密压缩包的解密,以及镜像库恢复等。 For security reasons the application server, using the operation command after the client generates encryption, application server scheduled tasks scheduled a manner independent of the application decryption instruction, according to the type of instruction, the corresponding exe scheduling, enabling the backup file encryption archive decryption, and image library recovery.

[0044]实施实例说明:在某行业存在网络密级不同的内外网。 [0044] Embodiment examples illustrate: Different dense network and external network in an industry. 某ERP系统在内外网中分别基于三层架构独立部署。 An ERP system inside and outside the network are based on three-tier architecture deployed independently. 网络间数据流转方式如附图2所示。 Inter-network data transfer means such as shown in Figure 2. 非涉密网中,备份,压缩加密, 下载,校验文件生成。 Non-classified network, backup, compression and encryption, download, check file generation. 非涉密网与涉密网间,刻盘,木马病毒查杀,文件摆渡。 Non-classified network to the classified network, dials, killing the Trojan virus, file ferry. 内网,备份文件校验上传,文件解压缩,恢复镜像库。 Network, verify backup files to upload, extract the files, restore the image library.

[0045]外网应用服务器上,通过制定计划任务备份,加密压缩,删除指定时间段之前的备份文件。 [0045] on the extranet application server, through the development of a scheduled task backup, encryption, compression, delete the backup files before the specified time period.

[0046]内网ERP客户端上,通过配置导库的必要信息,形成解压缩指令以及导库指令。 The [0046] network ERP client, the necessary information through repository arranged guide, and the guide form decompressed instruction command libraries. 内网应用服务器上,独立部署一个应用程序,通过计划任务调度,固定时间间隔判断指令文件是否生成,指令文件存在则,解密操作指令,调用应用服务器端相应的应用程序。 The network application server to deploy a separate application, task scheduling by scheduling, fixed time interval is determined whether an instruction file generation instruction file exists, the decryption operation command, the application calls the appropriate server application. 从而实现文件解压,以及镜像库恢复。 In order to achieve the file extraction, recovery and image library.

[0047]上述具体实施方式仅是本发明的具体个案,本发明的专利保护范围包括但不限于匕述具体实施方式,任何符合本发明的一种基于oracle数据库备份及恢复的方法的权利要求书的且任何所属技术领域的普通技术人员对其所做的适当变化或替换,皆应落入本发明的专利保护范围。 [0047] The above specific embodiments are merely specific cases of the present invention, the scope of protection of the present invention include, but are not limited to particular embodiments described dagger, consistent with the present invention, any of the claimed oracle database based backup and recovery methods of claims and any person of ordinary skill in the art, variations or replacement thereof suitably made, are intended to fall within the scope of protection of the present invention.
