- If the value of the SGAMAXSIZE parameter is not set, then decrease the size of one cache and reallocate that memory to another cache if necessary. Alternatively, you can set the value of the SGAMAXSIZE parameter to be larger than the sum of all of the SGA components, such as the buffer cache and the shared pool.
- LOGBUFFER = 200M You issue the following command to increase the value of DB8KCACHESIZE: SQL ALTER SYSTEM SET DB8KCACHESIZE=140M; Which statement is true? It fails because the DB8KCACHESIZE parameter cannot be changed dynamically. It succeeds only if memory is available from the autotuned components if SGA.

LOG_BUFFER specifies the amount of memory (in bytes) that Oracle uses when buffering redo entries to a redo log file.

Nov 10, 2005 Auto tuned SGA parameters dbcachesize sharedpoolsize largepoolsize javapoolsize These parameters are called auto tuned because automatic shared memory managment can dynamically change the sizes of these pools if it is enabled. DBCACHESIZE The value of this parameter affects the size of the SGA: It sets the default buffer pool. According to metalink note. Tag: oracle stream pool size ORA-00832: no streams pool created and cannot automatically create one / stream pool and expdp. July 12, 2014 arcsdegeo Leave a comment. If, sgatarget is equal to zero then SGA is not auto-tuned. SQL show parameter sgatarget. Providing minimum (explicit) settings for those auto-tuned parameters is recommended to help the database make the 'best choices' with memory moves in the SGA.

Redo log entries contain a record of the changes that have been made to the database block buffers. The LGWR process writes redo log entries from the log buffer to a redo log file.
The log buffer size depends on the number of redo strands in the system. One redo strand is allocated for every 16 CPUs and has a default size of 2 MB. Oracle allocates a minimum of 2 redo strands per instance. When the log buffer size is not specified, any remaining memory in the redo granules is given to the log buffer.
