What do you mean by thread?

Friends,

DB: 10.2.0.4

While I went to the documentation of the oracle dataguard, I saw the word thread...
in fact, what it means thread?

* "(maximum number of logfiles for each thread + 1) ' * maximum threads" * "

and that means thread?

* "The following statement adds a group of log files waiting for new Redo to a database of pending and assigns it to put ON 5: *"

* SQL > ALTER DATABASE ADD LOGFILE ENSURES WIRE 5 *.
* 2 > ('/ oracle/dbs/log1c.rdo','/oracle/dbs/log2c.rdo') SIZE 500 M; *
*"*

What is a node or server or the process? is that the meaning of this thread will be the same in all documentation for oracle concepts?

Thank you

Hello;

Archived redo log thread number.

The single instance configurations will be that a single thread, then the thread number will be 1.

Each database instance has its own groups of online redo logs. These groups of online redo logs, multiplexed or not, are called an instance of online redo thread. In typical configurations, only one instance of database accesses an Oracle database, then have another thread. When running Oracle Real Application Clusters, however, two or more bodies are simultaneously accessing a single database and each instance has its own thread.

Best regards
