Look at me today this single node 12C RAC, suddenly feel that the disk group of OCR is called +dg_sys a little uncomfortable, want to change to +SYS_DG. The approach is to migrate the Ocr/votedisk/asm SPFile to an existing ASM, and then modify the disk group name and finally migrate to the new name Disk group (this process +DG_SYS-GT;+DATA-GT;+SYS_DG)Current operating conditions[Grid@xifenfei ~]$ crsctl sta

Tags: Oracle OCR Backup and RecoveryIntroduction to 1.OCR Disks The problem with forgetfulness is that each node has a copy of the configuration information and the configuration information of the modified node is not synchronized. Oracle's solution is to put this configuration file on the shared storage, which is the OCR Disk. The whole
Brief introductionOptical character recognition (ocr,optical Character recognition) refers to the process of scanning text data, and then analyzing and processing the image files to obtain the text and layout information. OCR technology is very professional, generally many printing, printing industry practitioners use, can quickly convert paper data into electronic data. About Chinese
I haven't written a blog for a long time because of my work recently. (see a lot of comments and messages, can not reply to each one)Before the New year Oracle organized an internal programming marathon, when the choice of the topic is OCR-related, but the effect is not very good, have been thinking of the code to re-organize, optimize the effect.At present with the domestic internet fire of a mess, it seems to have led to the development of image pro
Tags: OCR damageScenario Description:To do the OCR Backup recovery experiment, OCR has 4 automatic backup. After you replace the OCR disk with +OCR2 (/DEV/RAW/RAW4), use Ocrconfig-manualbackup to manually back up OCR, and then perform a DD operation on the/DEV/RAW/RAW4 after
The biggest tragedy is that the database is broken and the backup is gone. It reminds me of a popular phrase in the past few years: the biggest tragedy is that people are living and money is gone. In short, backup is more important than everything. Scenario: In the 11G ocr, the asm disk is accidentally deleted by the user and all the backups are deleted by mistake, and the olr is damaged. So far, the tragedy has been repeated. Recovery Process: (in fa

The following introduction comes from search:OCR (Optical CharacterRecognition, optical character recognition) refers to the process by which an electronic device (such as a scanner or digital camera) examines printed characters on a paper, determines its shape by detecting dark and bright patterns, and then translates the shape into computer text using a character recognition met
Http://www.jb51.net/article/89955.htmhttps://pythontips.com/2016/02/25/ocr-on-pdf-files-using-python/You may have heard of using Python for OCR recognition operations. In Python, the most famous library is the tesseract that Google has funded. With tesseract, images can be easily identified. Now the question is, what if you want to make OCR recognition for a PDF
