1. directpath reads description
In versions earlier than Oracle 11g, if a full table scan is performed on a large table, the wait event is: DB file scattered read; in 11g, if a full table scan is performed on a large table, wait event is: direct path read; that is, in 11 GB, full table scan of large tables directly reads data blocks into the PGA region of the session. (For more information, see the following example ).
In 11g, data blocks are directl

[Boiled ASP. NET Web API2 methodology] (3-2) Direct routing/attribute routing, api23-2
Problem
How can I define a route in a way closer to a resource (Controller or Action.
Solution
You can use Attribute routing to directly declare a route at the resource level. You only need to simply use RouteAttribute on the Action, and then pass a relevant routing template. Attribute routing and centralized routing basically have the same meaning in the routing t
Impact of Direct Memory on jvm, jvm memory
Direct Memory
Direct Memory is an important issue. First, it is neither a part of the running data zone nor a part of the Java Virtual Machine specification. This issue is mainly related to NIO after java1.4, an I/O Method Based on channels and buffers. It can use the Native function library to directly allocate off-he
Basic idea:Insert a record into the sorted ordered table to get a new, sequential table with a 1 increase in the number of records. That is, the 1th record of the sequence is considered to be an ordered subsequence, and then inserted from the 2nd record one after the other into the entry until the entire sequence is ordered.Important: Set up Sentinel as a temporary storage and judgment array boundary.Example of a direct insert sort:If you encounter an
It took one night to study some people's claim that "you can use Cisco SLA to monitor a non-direct connection network down to delete a local static/default route", which I personally think is impossible.
Some people's original intention should be to avoid invalid data packets forwarded by the router. Because the non-direct connection network is disconnected, the local router still forwards the data packets
Background: originally although has learned the data structure, sorts some, but did not have the good studious, now review .Business: 1. Direct Insert Sort Go directly to the encyclopedia: each time you take out a number in an unordered array, compare it to the number in the ordered array, and plug it into place until the unordered table is empty and the ordered table is full.The principle is very simple, as far as I am concerned, the first thoug

center, take a non-identical automorphism transform \ (\tau (a) =b\neq a\) and inner automorphism \ (\sigma_a\), thus having \ (\tau\sigma_a=\sigma_a\tau\), You can then prove that \ (a^{-1}b\) is the center of \ (g\). Thus if \ (\text{aut}\:g\) has a center, then \ (g\) also has the center. Conversely, if \ (g\) has no center, then \ (\text{aut}\:g\) has no center. Consider the following questions: • proof \ (s_n\) and \ (\text{aut}\:s_n\) are no central groups; • proving that the automorphi

(I) direct path loading and buffer cache
Data inserted in the direct path is directly formatted as an Oracle block from PGA without passing through the buffer cache.
Then, a common Oracle Server Process writes data blocks to data files.
DBWn is not required because it does not pass through the buffer cache.
For example, if Table a is available, you need to insert data in Table B into Table a. Under normal i
