Open source OCR library and opensourced OCR Library
I suddenly remembered how to create a forum posting machine, but now most of them require image authentication, and an OCR library is required to recognize images. So I found it on the Internet and there are many implementations:

Managing Oracle clusterware (OCR)Oracle Clusterware places the configuration information of the entire cluster on shared storage. The information includes the list of cluster nodes, the ing between cluster database instances and nodes, and the CRS Application resource information. The storage location is on the OCR Disk. in the entire cluster, only one Node can perform read and write operations on the

The storage data of the 11gR2 RAC system is completely lost. The software of all nodes is installed on the local disk, and the local disk retains the OCR backup, the following describes how to restore the normal operation of Clusterwar

OCR is used to solve the amnesia problem in the cluster,
The Cluster Environment configuration file is not stored in a centralized manner, but each node has a local copy. When the cluster runs normally, you can change the cluster configuration on any node, in addition, this change will be automatically synchronized to other nodes.
There is A special situation: node A is

Oracle Clusterware puts the entire cluster's configuration information on shared storage, which includes a list of cluster nodes, a cluster database instance to a node map, and CRS application resource information. It is also stored on an OCR disk (or OCFS file). Therefore, the importance of this configuration file is self-evident. Any action that makes an OCR configuration change is recommended to back up

However, if you have manually created a database (create database) and manually editedThe listener file is not recorded in OCR. This requires the Administrator to use the srvctl add command to manua
OCR is equivalent to the Windows registry. For Windows, all software information, users, configurations, and security are stored in the registry. In the same way, all cluster-related resources, configurations, nodes, and RAC databases are stored in this warehouse. If OCR is damaged, the cluster Service Startup exception occurs. You need to fix OCR. Therefore,

1. Introduction to OCR
OCR (optical Character recognition)-refers to an electronic device (such as a scanner or digital camera) that checks the printed characters on the paper, determines its shape by detecting dark, bright patterns, and then translates the shape into computer text using c

Oracle's solution is to put this configuration file on the shared storage, which is the OCR Disk. The whole
Sometimes we get text pictures from scanners, digital cameras, or high-definition cameras, so we can use Office's own OCR program to turn these pictures into Word documents, which is much easier than looking at pictures alone.

learned that all the programs that use the OneNote OCR function also use the WinForm program. The OneNote program will be started in the background when the program is running. So I guess it may be because of this reason that it can only be made into a desktop program.

Before adjusting the cluster, for example, adding or deleting nodes, you should back up OCR once. You can use export to back up to the specified file.

OCR corresponds to the registry of Windows. For Windows, all software information, users, configuration, security, and so on are all in the registry. And the cluster, again, all cluster-related resources, configurations, nodes, and RAC databases are all in this warehouse.

Oracle recommends that you back up OCR when you adjust the cluster, such as before adding or deleting nodes. You can use export to back up to a specified file. If replace or restore is performed, we recommend that you use the cluvfy comp ocr-n all command to perform a comprehensive check.
Run the following command under an oracle user:
