In the production environment, was cannot be restarted. What should I do ?, What should I do if my phone keeps restarting?

In the production environment, was cannot be restarted. What should I do ?, What should I do if my phone keeps restarting?
Some time ago, I went online and encountered a jndi fault. Why? That is, there was no problem in the test environment, but the production database could not be connected in the production environment. At that time, the problem was found, the resource file resources of the jndi that is automatically generated by the ibm tool in the test environment. xml, deleted at the time, and restarted the server, which is invalid. Later, I thought this was definitely caused by the was cache, So I imagined the cause of the cache. Finally, I restarted was in the test environment and solved the problem, however, it is not possible to restart the was in the production environment. Therefore, I am sleepy for the time being. Later, the so-called leaders said that he went to the chief architect to check whether there was a solution, but the time was not enough, after two days, I still said that there is no way. I came back that afternoon and thought about it. Since was cannot be restarted, it is also a cache problem, I just need to change the application name. Indeed, on Monday, I changed the jndi name to solve the problem.
What should I do if my computer cannot be restarted? Because Windows XP has more and more features and is easy to use, your hardware facilities are advanced enough to run at a high speed. I am sure that only upgrading hardware can satisfy XP's greedy needs? We use various software to speed up Windows XP!

Registry optimization solution

1. Enable CPU L2 Cahce

Create a New Dword Value in the Registry HKCU_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management:

SecondLevelDataCache modify the value when the CPU Level 2 Cache size is filled in using a 10-digit value by modifying the Dword Value SecondLevelDataCacheCPU2 cache to 256KB restart the computer

2. Modify disk cache to accelerate XP

Disk cache plays a vital role in XP operations. By default, files on the I/O page are relatively conservative. It is better to use the same disk cache in the same memory.

Registry HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ Session Manager \ Memory Management \ IoPageLockLimit modify its hexadecimal value (64 M: 1000; 128 M: 4000; 256 M: 10000; 40000 m or larger)

3. Remove menu Delay

Remove the delay when sliding out the menu to a certain extent. Speed up XP. Modify the key value HKEY_CURRENT_USERControl PanelDesktop. Specifically, modify the key name MenuShowDelay. You only need to change the value to 0. The change takes effect only when you need to restart the computer.

4. Specify the Process Order

At the same time, press Control + Alt + Delete and click Processes (process) on the tab, check the check box. Currently, all processes are running. You only need to right-click the process and move the Set Priority> (Set the Priority) to assign more process time to the program) select the priority of the program. When I receive the email, I will set the 3DMAX standard. When I leave the computer, I will increase the priority to higher real-time. The sample computer is more focused on processing 3D actions more quickly.

5. Cancel reserved bandwidth for Windows XP Professional Edition

Because the 20% default reserved bandwidth needs to be set on the Professional Edition network, it is not useful for some reserved bandwidth users. Use the Group Policy Editor to cancel reserved bandwidth.

Start → run the input gpedit. msc open the Group Policy Editor and find the computer configuration → manage the template → network → QoS packet scheduler select the right-side restricted bandwidth selection attribute open the picture select disable is very good for Modem users-released keep bandwidth to speed up online browsing and downloading!

6. Check the scheduled task in Windows XP

Generally, when Windows XP is connected to its computer, it will check that all the scheduled tasks on the sub-host of the other side will make it so annoying to wait for 30 seconds. Let's disable the process: Registry searching

HKEY_LOCAL_MACHINE \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \

RemoteComputer \ NameSpace should have the {D6277990-4C6A-11CF-8D87-00AA0060F5BF} key simply to delete and restart the computer Windows and then check the scheduled task has significantly improved!

Driver optimization scheme

1. Intel 8XX chipset must be installed with Intel Application Accelerator to install system optimization. Download from Intel Official Website

2. VIA4in1 is required for installing patches on non-Intel chipset boards.

3. Try to use the driver that has passed the WHL certification driver and has passed the Microsoft hardware lab certification. The stability and compatibility have a major advantage.

Its Optimization Scheme

1. Start Acceleration

Although Windows XP has a higher startup speed than Windows 98, it also accelerates the startup of the bootvis.exe file. Choose Trace> Optimize in the menu, and the System will prompt whether to restart or choose to restart. If you do not change the System for a period of time, the dialog box will pop up automatically. lines on the box

The system analysis and other prompts do not perform direct analysis. The startup speed of the sample after analysis is completed is significantly improved.

2. Remove necessary services

Every Time Windows XP is started, many services are started. Some of these services are useless to multiple users and occupy memory. Next let's look at which services need to be disabled.

Click Start → run the input command services. msc open the service peer box (Note: You must log on as an administrator or a member of the Administrators group to complete the computer and network connection process, the Network policy setting also prevents you from completing this step)

Clipbook Server (Folder Server): the service allows users to view the folder on the network. I strongly recommend that you manually start the folder and then publish information on the program network.

Messenger (Message): Alerter is disabled for sending and receiving information on the network and can be started manually safely.

Printer Spooler (Printer processor): it is recommended to manually start or close the Printer if no Printer is configured.

Error Reporting Service (Error report): It is recommended that you manually start an Error report when running services and applications in non-standard environments.

Fast User Switching Compatibility (quick User Switching Compatibility): it is recommended to manually start

Automatic update

Net Logon (network registration): processes network security features like registration information and manually starts them

Network DDE and Network dde dsdm (Dynamic Data Exchange)

Nt lm Security Support (nt lm Security Support Provider): network applications provide Security protection and recommend manual startup.

Remote Desktop Help Session Manager (Remote Desktop Help Manager): it is recommended to manually start

Remote Registry: enables Remote users to modify the Registry Settings on this computer.

Task Scheduler

Uninterruptible Power Supply

Windows Image Acquisition (WIA)

3. Use a fixed virtual cache

We recommend that you set the memory and small values to MB and the physical memory size of the tube.

4. Make sure that the memory usage is preferentially used by the program CPU Scheduler for the program

First Open System Properties select Advanced Tab performance bar click set button to open performance option box open Advanced Tab processor plan bar select program memory usage bar Select Program Click OK to exit

5. Clear pre-read files

When XP is used for a certain period of time, files in the pre-read folder will become larger, and dead chain files will slow down the system time. We recommend that you delete some files regularly (c: \ windows \ prefetch)

6. Reduce disk scan wait time

In Dos, type chkntfs/t: 0, and the value 0 indicates the waiting time is 0 seconds.

7. Disable disk Indexes

XP records all files, and then quickly searches for files that are frequently searched. Specific Method: open my computer, right-click the drive, select properties, and then use the index to quickly search for files
What should I do if my computer cannot be restarted? Software

1. Virus destruction

Computer viruses have also emerged since the advent of computer science. In today's society, the spread of information artery viruses is more convenient, and it often interferes with and destroys the computer. during the attack, the system will be prompted to automatically start 60 seconds. In fact, in the early DOS era, computers can be automatically restarted with fewer viruses.

We use the new version of anti-virus software to eliminate viruses. We will find that viruses are stored. When people access the Internet, they are maliciously intruded into the computer and placed Trojans. The other party can remotely control the computer. the switch activity also includes restarting the computer. For some Trojans, it is easy to clear and reinstall the operating system.

2. System File Corruption

When the system file is damaged, the font under the KERNEL32.DLLWin98 FONTS directory under Win2K and other system runtime basic files are damaged. The system cannot complete initialization and force restart to perform the test. The font under the WIN98 directory is FONTS rename. Try again. When the system is powered on again, the computer will be disconnected and restarted again.

For a fault that cannot enter the normal desktop, only the installation can be overwritten or reinstalled.

3. Timing software or scheduled task software works

When the task bar is configured to restart or load some work programs, when the scheduled time comes, the computer will start again. In this case, we open the startup Item to check whether you are familiar with the execution file or its scheduled work program. it shields and re-starts the check. When we run it, directly enter the Msconfig command to select the startup Item.

Ii. Hardware

1. Stable mains voltage

When the mains voltage is less than V, the computer will automatically restart or shut down. due to fluctuations in mains voltage, we sometimes feel that the computer will be falsely recognized and automatically restarted.

Solution: for areas with regular power supply stability, we purchase UPS power supplies or 130-260V wide switching power supplies to ensure computer stability.

2. Poor contact between plug-in or power outlet

On the market, most of the power plug-ins with good quality internal contacts are manually welded and often use acidic flux samples, which may easily lead to the use of solder joints oxidation and lead to open circuit or leakage between the FireWire and zero line because of manual welding and the use of phosphorus brass sheet elastic difference how long is it easy to lose elasticity, resulting in good contact with the host or display power plug, resulting in a large contact resistance, a large amount of heat will occur during a long period of work, resulting in the host restarting or display black screen flashing

In addition, we can use wall sockets in our homes. Most wall sockets are installed using professional sockets. The internal wiring is very standard. Special sockets. We often use high-power heaters, which may cause internal heating, oxidation, and intermittent power failure. computer restart or blinking display

Solution:

① To save money and purchase inexpensive power supply plug-in buy some famous brand power plug-in because of its internal machine automatic installation of crimping not using manual welding

② For the Internal Failure of the wall socket, change the host to the wall socket, and try again.

3. Adequate computer power supply or poor performance

This scenario is also quite common. When we add new devices to our host and replace the high-end graphics card, add a burner, and add a hard disk, it is easy to show that when the host is working at full speed than running a large 3D game for high-speed burning or preparation for reading when the disc is just started, dual hard disk copy data will be able to cause power protection due to the instantaneous power supply, and the output will be stopped because when the power supply stops and the output load is reduced, the power supply will be restarted again because the protection recovery time is short. host restarts automatically

In other cases, the performance of the host switch power supply is poor. Although the voltage is stable, the harmonic content of the output power supply is too large, which may lead to frequent host crashes or restarts. In this case, we use a multimeter to test the voltage. regular replacement of excellent power supply for troubleshooting

Solution: Change the high-power computer power supply

4. The mains plug of the host switch power supply is loose and the contact is not tightly inserted.

In most cases, the power cord of the host on the DIY machine is not certified by 3C and the power outlet is used together. When we shake the table or touch the host, the host will automatically restart and be accompanied by a slight electric fire. voice

Solution: replace the high quality 3C certified power cord

5. The main board power supply ATX20 socket has good contact with virtual Welding

Common Faults: when the main host is working normally, move the ATX20 pin plug to check whether the host will automatically restart and check whether the internal Reed of the 20 pin power plug is oxidized, which may also lead to high contact resistance. the connection line at the end of the 20-pin plug is sometimes required when the host crashes or restarts due to good contact.

Solution:

① Solder joints on the main board are soldered directly with a soldering iron. Note: When soldering computer boards such as the main board, hard disk, and video card, the soldering iron must be properly grounded or unplug the power plug during welding.

② Good power supply problems, good power supply replacement

6. CPU Problems

When some function circuits in the CPU are damaged, the second-level cache is damaged, and the computer can be started or even enter the normal desktop for normal operations. When a special function is enabled, the computer will be restarted or the machine will be suspended to play the VCD game.

Solution: try to block the second-level cache (L2) or level-level cache (L1) in CMOS to check whether the host can run normally; use the CPU directly to replace and eliminate the possibility of normal operation. Even though it is slower, it will save money.

7. Memory problems

When a chip on the memory stick is completely damaged, it will pass self-check (POST must be set for most of them) during operation, functions may fail due to a large amount of memory heat, and the system restarts unexpectedly. In most cases, if the memory is damaged, an alarm is triggered. If the memory is damaged, an alarm is triggered, and a power-on fault is triggered, the troubleshooting method can be used to quickly determine the fault location.

8. Optical Drive Problems

When the internal drive is damaged, the host may be slow to start or the job may be restarted through self-check. In this case, we have changed the Drive drive and the power consumption of the drive may be the same, so you need to know that although the optical drive ATPI Interface the same as the manufacturer's pin definition is the same. When there is a problem with the hard drive line, it will produce no problem with the use of a certain brand of Optical Drive. Please note that

9. The RESET key quality is incorrect.

When the RESET switch is damaged and the internal Reed is always in the transient position, the host cannot perform power-on self-check. When the RESET switch is weakened or the button on the chassis is pressed, the use process may occur due to occasional touch of the chassis or normal use status. when the RESET switch can be pressed, we must carefully check the switch for replacing the new RESET button or refresh the external button of the chassis.

In other cases, the host is automatically restarted because the insulation layer is too stripped when the RESET switch leads are welded in the chassis. In addition, the RESET switch wires are too close to each other when used for multiple times, causing a collision.

10. Automatically restarts when the network adapter or parallel port, serial port, or USB interface is connected to external devices.

In general, due to peripheral faults, this is worse than the printer parallel port damage, a pin to the ground short circuit USB device damage to the ground short circuit Nic work standards, etc. When we use some equipment, the computer will be caused by a short circuit due to a sudden power supply. restart

Iii. Reasons

1. heat dissipation or temperature measurement failure

CPU cooling is good, there are often problems with CPU radiator fixed card off CPU radiator and CPU contact between foreign body CPU fan for a long time using the radiator dust too much some situations will lead to CPU cooling good accumulation temperature too high Automatically Restart

There is also damage to the temperature sensor under the CPU or P4 CPU internal temperature measurement circuit damage on the motherboard BIOS there are bugs under certain special conditions temperature quasi will cause the host to work process automatically protective restart

When the CPU protection temperature is too low in CMOS, the host will automatically restart.

2. fan speed failure

When the speed control circuit of the cpufan is damaged or the speed control line is intermittently broken, the fan speed will be mistakenly stopped on the motherboard, And the fan will be automatically shut down or restarted. We can check that the CPU fan turns normally and the speed is also normal.

3. Strong Magnetic Interference

When electromagnetic interference occurs, the computer crashes and restarts. In many cases, the interference also causes some interference, including CPU fan, chassis fan, graphics card fan, graphics card, motherboard, and hard disk interference, as well as external power lines. inverter air conditioners and even large equipment such as automobiles interfere with our hosts. Poor performance or poor shielding may cause unexpected host restarts or frequent crashes.

Computer problems are strange. We can understand the basic working principles of computers. When we eliminate computer software and hardware faults, we will be able to handle the problems. I hope this article will help you. Please support me a lot.
