Method 1, unplug the power, wait a moment after reboot
PS4 sometimes because of the sudden loss of power, there will be some small problems, we just have to restart or power off once it can be used properly oh.Method 2, manually tighten the drive door screws
Some players said that the problem is the real problem is that the CD-ROM drive due to the inability to properly huff and puff disc caused by the host to carry out the operation

Sony announced that it will start to push firmware updates to the PS4 gaming console tomorrow, which supports remote play (streaming), allowing users to implement streaming on their computers.
This version of the firmware has actually been tested for one months, but previously only the Windows system support, the Mac's streaming function has not appeared.
Streaming can allow PS4 to send audio and v
According to foreign media reports, a master named Osirisx in the online release of video, and said he gave PS4 installed Linux system, successfully ran the Steam OS platform game "fortress."Hackers successfully loaded Linux on PS4Sony and Microsoft introduced the Ps4/xbox one with a PC-like hardware architecture, which makes it possible for the host to run a Linux system. Osirisx said in the video that he
This is useless from the beginning, and it does not help any kind of questions. Although I understand RT, Tex, and buffer, I feel that it is useless to catch bugs. Therefore, it has always been like a wizards that rely on intuition and use scientific methods to test. In fact, it is to let PS return some values for testing.
One day, things changed, and one day I learned from a colleague that the replay button.
In fact, it has always hindered me from reading the buffer. The shader should look
The E3 Nintendo has no new handheld (the legendary XDs. hehe) and the pocket of the message, was sprayed very seriously, Sony's FF7 re-Seihan and Shamu 3 is the highlight.and Shamu 3 of the crowdfunding speed is said to record, the player's feelings of victory. The author saw that there were also dozens of players in the country who sponsored the knife. It is said that 2 million dollars is not enough for this development, and this time crowdfunding is to test the feelings of players to increase

When the client sends a connection request to the server, the server listens to the client's request. In dedicated server mode, a server process is derived from the server to represent the client's request, server process then initiates a connection to the instance to create a session, and PGA is allocated and used by server process.

In Oracle10g, you need to set workarea_size_policy to AUTO, and set the pga_aggregate_target parameter to implement PGA memory management.
In Oracle 10 Gb, you need to set workarea_size_policy to AUTO, and set the pga_aggregate_target parameter to implement memory management of PGA.

you don't use Java, giving 30M is usually enough.
Data buffer, in the previous settings, where the memory can be provided to Oracle, should give data buffer = (Db_block_size * db_block_buffers)
It can be db_cache_size in 9i.
There are 2 other important parameters we need to be aware of.
Sort_area_size and Hash_area_size

PGA (Program global area) is an important component of Oracle Systems. The total overhead of the Oracle database for system memory is PGA + SGA. SGA masterIt must be composed of database cache (shared SQL zone and PL/SQL zone) and data dictionary cache. PGA contains a set of server processes derived from the client connection server. Each server process hasPrivat
Oracle recommends that the OLTP (on-line TransactionProcessing) system accounts for 80% of the total system memory, and then allocates 80% to SGA and 20% to PGA. That isSGA = system_total_memory * 80% * 80%PGA = system_total_memory * 80% * 20%1. Global zone of the SGA System

PGA is the dedicated memory of a process and never allows access by other processes. You can use the C language to call malloc () allocation during runtime to dynamically scale up or down. Furthermore, PGA will never be allocated in the SGA of oracle, and is always allocated locally by the process. PGA is a key role between a user and an oracle instance. The most
