We all know that Informix needs a log, but what each log does, what it means, and so on, we do a discussion below: The first thing to note is that there are two types of Informix logs: One is the physical log, which holds the image of the data, and the other is the logical log, which is used to store the operation of everything. In the initialized configuration, the physical and logical logs are not store

Brief introduction Editor's note: In the work of the DBA, backups are becoming a chore that is not often considered. However, any good DBA can tell you that when a system failure occurs, the data should be recovered, and the backup will suddenly become the single most important thing for you and your management chain. Because the integrity of backups is critical, you need a backup tool that ensures integrity. What's the answer? Informix On-bar. As t

INFORMIX uses the lock technology to solve the concurrency control problem of accessing the same object when multiple users access the database. INFORMIX supports complex and scalable locking technologies. Lock type INFORMIX has three different types of locks. They are used in different cases. 1. SHARED lock The SHARED lock only retains the readability of object

We all know that informix requires logs. However, we will discuss the usage and significance of each log as follows: The first thing to note is that there are two types of informix logs: Physical logs used to store the front image of data, and logical logs used to store the operation process of all things. In the initial configuration, physical logs and logical logs are not stored in the root disk space. Th

Since the code set of the informix database is set to a en_us.8859-1, Chinese characters cannot be properly displayed due to this incorrect Character Set setting when using the drivers of csdk 2.8 and later. Here is a thorough solution: The omnipotent Internet must keep this article forever! Informix CSDK before 2.8, Garbage In, Garbage Out mode is used by default to process Chinese characters, if DB_LOC

Data fragmentation allows data storage to be controlled at the table level. "Table Fragmentation" is a feature of the Informix database. Users can group records or indexes in a table and store them in different locations so that data can be stored on multiple disks, thereby reducing competition for disk I/O. The scheme of data slicing and a set of dbspace stored in the fragment data constitute the "slicing strategy". There are two basic types of data
