When more than 64 logical CPUs exist, Oracle db instances in Windows will be hang (suspended) and oraclehang
Bug 9772171-Database startup hangs on Windows when machine has more than 64 cores [ID 9772171.8]
This article has already stated that the bug has been fixed (fixed) in 11.2.0.2.
Now 11gR2 has released 11.2.0.4, and 11.2.0.4 is the final 11gR2 version. Therefore, we recommend installing 11.2.0.4 and the latest psu.

The latest psu can be found in this article: Oracle Database, Networking and Grid Agent Patches for Microsoft Platforms (Doc ID 161549.1 ),
---> Note: the psu mentioned above is not accurate because the small oracle patch in windows is not called psu or bundle patch.




My computer is always automatically restarted and started slowly'

Four reasons for the computer's own hot start is a headache, because there is no time to save the disk, the design is about to be completed will be abandoned, busy. The cause is summarized as follows: (1) virus interference may occur. Immediately use the latest anti-virus software for antivirus. (2) it may be that the output voltage of the computer power supply is unstable. It is recommended that you have a professional test. If the mains supply is unstable, you can buy a voltage regulator before entering the computer. If it is a power failure (such as soft breakdown of the internal capacitor of the power supply causes a short circuit and generate self-protection), replace it quickly to avoid greater losses. (3) If the CPU has poor heat dissipation and the temperature is too high, it will cause hot start. Check whether the fan turns normally. Clean the fan in time and use good quality lubricating oil. (4) There are too many peripherals that require power supply (such as optical drives and USB devices). The actual power during operation exceeds the rated power, and the power supply with poor Overload Capability is automatically protected and restarted, we recommend that you replace the high-power supply. The computer cannot be started normally. In many computer faults, failure to start properly is the most headache for users. If you want to accurately diagnose the failure of computer startup, you must first understand the startup process. When we press the power switch, the power supply starts to power the motherboard and other devices. At this time, the voltage is not completely stable, the motherboard control chipset sends a Reset (Reset) signal to the CPU Based on the CPU clock speed setting in CMOS to initialize the CPU. After the voltage is completely stable, the chipset removes the Reset signal, the CPU immediately runs a jump command from the address FFFF0H and jumps to the real startup code in the system BIOS. The first thing the system BIOS needs to do is to perform POST (Power On Self Test, Power-On Self-check ). The main task of POST is to detect some key devices in the system (power supply, CPU chip, BIOS chip, Timer chip, data sending and receiving logic circuit, DMA controller, interrupt controller and basic 64 K memory and memory ). refresh circuit, etc) whether it exists and can work normally, such as memory and video card. After the self-check is passed, the system BIOS will find the BIOS of the display card, and the video card BIOS will initialize the display card. The display will start to display. Since then, the system has the most basic operating conditions, you can diagnose and test other parts on the motherboard. If a fault is found, a prompt is displayed on the screen, but the system will not crash. Then the system BIOS checks the CPU type and operating frequency, then test all the memory capacity of the host. After the memory test is passed, the system BIOS starts to detect some standard hardware devices installed in the system, including: devices connected to hard disks, CD-ROM, floppy disks, serial interfaces, and parallel Interfaces, in this process, most new versions of the system BIOS also need to automatically detect and set memory parameters, hard disk parameters and access modes. After the standard device is detected, the plug-and-play code in the system BIOS starts to detect and configure the plug-and-play devices installed in the system. After a device is found, the system BIOS displays the device name, model, and other information on the screen, and allocates resources such as interrupt, DMA channel, and I/O port to the device. Finally, the System BIOS updates the ESCD (Extended System Configuration Data, Extended System Configuration Data ). After the ESCD data is updated, the startup code of the system BIOS performs the last task, that is, starting from a floppy disk, hard disk, or optical drive according to the boot sequence specified by the user. Take disk C as an example. The system BIOS will read and execute the Master Boot Record on the hard disk. The Master Boot Record will then find the first active partition from the partition table, then read and execute the Partition Boot Record of the active partition, And the Partition Boot Record reads and executes IO. SYS, which is the most basic system file in Windows. IO. SYS first needs to initialize some important system data, and then shows the familiar blue sky and white clouds. In this picture, Windows will continue to perform DOS and GUI (graphic user interface) some of the boot and initialization work, everything ends smoothly, the computer starts normally. After learning about the Startup Process of the computer, we can judge the fault. Next we will start the diagnosis and treatment based on the fault phenomenon: Symptom 1: The system cannot be started at all, and the power indicator is unavailable, do not listen ...... remaining full text>
