For example, in the early days of planning and

Oracleblockcorrupt Bad blocks In general, oracle's Bad blocks can be divided into two scenarios: physical damage and logical damage. The physical damage is caused by storage and other reasons. As a result, oracle finds that the checksum of the block is inconsistent when processing the data block. Most of the logical damages are caused by oracle bugs or memory errors. By checking the checksum of data

In this article, I will use JavaScript to create a simple blockchain to demonstrate how they work internally. I will call it SavjeeCoin!

Mastering the definition and use of three blocks of code in Javacode block ConceptsThe code block itself is not a very difficult concept to understand, in fact, it has been used before. The so-called code block refers to the use of "{}" in a piece of code, depending on the location, the code block can be divided into four kinds: ordinary code block, building block, static code block, synchronous code block, where the synchronization code block this bo

Inode numbers in the partition are blocks 0 and 1. inodeblockInode numbers in the partition are block numbers 0 and 1. I believe that when you use Linux, you have encountered accidental deletion of file system data, whether it is accidental deletion or recovery of accidental deletion. Currently, many recovery tools are usually ext3grep and extundelete. Of course, this article does not talk about the use of these two tools, but describes what the inod

Before giving you a detailed description of Oracle free data blocks, let's first let you know the data stored in the rollback segment, and then give a comprehensive introduction to Oracle free data blocks, hoping to be useful to everyone. Here we will talk about the data stored in the rollback segment. If it is a delete operation, the rollback segment will record the data of the entire row, if it is an upda

1. Rman Backup is the default check for physical bad blocks. 2. If you want to check for logical bad blocks, you can use the following statement: $ Rman Target/rman> backup check logical validate database; Note that the above statement is only checked and will not be backed up. 3. If you want to perform a logical bad block check at the same time as the backup, you can use: $ Rman Target/rman> backup ch

Article Introduction: Bem represent blocks, elements (element), modifiers (Modifier). The meaning of these terms will be further elaborated in this paper. What is BEM? Bem represent blocks, elements (element), modifiers (Modifier). The meaning of these terms will be further elaborated in this paper. One of the most common examples of programming methodologies is object-oriented programming (OOP)

Data Block In an Oracle database, the block is the smallest unit of data file I/O and the smallest unit of space that can be allocated. An Oracle block consists of one or morecontiguous operating system blocks. Standard block size Use the db_block_size parameter when creating a database. It cannot be changed unless the database is re-created. Used for system and temporary tablespaces Db_cache_size specifies the default cache size for

1. What is bad database blocks? First, let's take a rough look at the format and structure of the database block-The database data block has a fixed format and structure, divided into three layers of cache layer, transaction layer, data layer. When we read and write data blocks, the database will check the consistency of the data blocks to be read and written, i
