LIST.In the long run, a large number of small chunks such as 1 K/2 K may be generated, with a large total space. However, if an SQL statement requires a CHUNK such as 4 K, it cannot request the required CHUNK, a Shared Pool fragment is generated, causing a ORA-04031 error.View the chunk size in the Shared Pool.

in a contiguous memory, and then call Ngx_http_write_ Filter for output. Ngx_http_write_filter is the last of the body filter, so the first body information of Nginx, after passing through a series of body filter, will finally call Ngx_http_write_filter to output ( There is a diagram to illustrate). Note here that Nginx will put the entire request header in a buffer, the size of the buffer is set by the configuration item client_header_buffer_size, if the user's request header is too large, thi

large different connection speed. We can adjust the buffering behavior with the following instructions. Can be set at http,server or location. It is important to keep in mind that the size sizes directive is configured for each request, so adding more than you need will affect your performance if there are many client requests at this time:Proxy_buffering: This directive controls whether buffering is enabled. By default, its value is "on".Proxy_buffers: This directive controls the number of Age

server settings are taken at the time of connection. If you are not using a shared service, then the configuration differs from the default worth of SDU that needs to be set on both the client and server side. For shared services mode, because the server side defaults to the maximum value, you only need to set the client's value. When the allocated information size is not 8192, you need to consider modifying the SDU size. The SDU size should be 70b larger than the allocated information size. If

greater than the advantages.2: Logical fields, such as gender fields, and so on, match too many records, and the table scan is comparable.3: Fields with very large field content, such as text, can greatly increase the space occupied by the index and the speed at which the index is updated.We say that SQL consumes system resources when maintaining indexes, so what resources does SQL consume when maintaining indexes? What problems will arise? How exactly can I optimize the index of a field?First:
