Linux thread private data --- TSD pool, linux --- tsd
All threads in the process share the data space of the process, so the global variables are shared by all threads. In some scenarios, a Thread needs to save its own private Data. In this case, you can create a Thread-specific Data TSD. Inside the thread, private data can be accessed by various interfaces of th
private data (TSD) to solve this problem.Third, thread-specific dataThreading Private data (thread specific) is a mechanism for storing and querying data related to a thread. This data is referred to as thread-private data or thread-specific data because you want each thread to have independent access to the copy of the data, eliminating the need to consider multithreading synchronization issues.

In a single-threaded program, there are two basic types of data: global variables and local variables. But in multithreaded programs, there is a third type of data: Thread data (tsd:thread-specific). It's very much like a global variable, where each function can call it like a global variable, but it's not visible to other threads outsi

During the catalog backup recovery process, the import job terminates abnormally under certain conditions. At this point, catalog will be in a damaged state: The original catalog can not continue to use, import job can not continue. This article mainly introduces an example of such a scene, then restores and proposes how to avoid this anomaly.
The schema that Rman uses to store database metadata.The catalog includes the following types of metadata:-data file and archived redo log backup sets and backup pieces-data file copies-archived redo logs and their copies-database structure (tablespaces and datafiles)-stored scripts, which is named user-created sequences of RMAN commands-persistent RMAN configuration settingsCreate Recovery Catalog1. Configuring the Recovery
When Rman Recovers Data, it can restore the control file and spfile with the help of catalog. Today, we have specially configured the catalog Database:

The system catalog is a collection of tables and views that contain important information about a database. A system catalog is available for each database. Information in the system catalog defines the structure of the database. For example, the DDL (Data dictionary language) for all tables in the database are stored in the system
Nocatalog Way is to use control file as a catalog, each backup to the controlling files to write a lot of backup information, control files will have more and more backup information. For catalog, you must first create a directory backup database and establish a recovery directory.
