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

Just happened to solve the problem. Find your pytesseract. py file and change the line tesseract_cmd = 'tesseract 'to tesseract_cmd = r 'C:/Program Files (x86)/tesseract-
language matching library.
We can see that, after simple training, we have improved the accuracy of the conversion of digital data. In addition to the advantages of tesseract can continue to learn, but also because the use of C + + written open source program, can use C # or C + + call and modify, is critical.
About Tesseract, about OCR, about the computer, there are too many worthy of their own to learn

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

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,
