The client configures the ASM instance to the wrong host, ASM1 runs in node 2,asm2 and runs at node 1, after De-config and Re-config, the ASM Alertlog a large number of errors: Symptoms: Note:attempting voting file refresh on DiskGroup GRIDNote:voting file relocation is required in DiskGroup GRIDNote:attempting voting file relocation on DiskGroup GRIDNote:attempting voting file refresh on DiskGroup GRIDNo

Windows: folder relocation and mobile users Key words: Mobile User: roaming Profile Folder relocation: Folder Redirection InWindowsThe NT era has supported the concept of mobile users.A mobile user is defined on the server. When a user works on a computer, the system automatically synchronizes the user files on the server, in this way, the user files on the server always contain all the latest user files.

In a Linux environment, Svn:authorization failed errors are reported using SVN Co (that is, SVN checkout)When using SVN co svn://localhost/temp.cc/data/temp.cc, it is reported: Svn:authorization failedPlease change your account to move out againSVN Co svn://localhost/g.cc/data/wwwroot/g.cc/--username SvnaccountEnter your user password when you are prompted.

1. Why do we need to relocate global variables? First, we need to study why we need to re-locate the global variables of bootloader. It is inevitable to define some global variables in the source code of bootloader. These global variables are placed in the Data Segment Storage Area of the compiled executable binary file. The bootloader image file is either run in the xip mode in the ROM or copied to one disk. the area defined as ramimage In the bib project file is used as a rom even though it is

First of all need to Zhu Youpeng teacher, this is in the study of Zhu Teacher's course after a little understanding, code is based on the teacher's source of learning after the writing.650) this.width=650; "src=" http://s5.51cto.com/wyfs02/M00/76/00/wKiom1ZG-_GSwV3fAAhrJH4QS6g868.jpg "title=" code.

Reposition PC Relative Reference (pc-relative reference relocation)The sample code (MAIN.C, SWAP.C) is shown in an earlier article, which is followed by an analysis of the target file.You can see that the call command calling swap in main is at section offset 0x1d, the opcode is E8, the operand is 32bit reference 0XFFFFFFFC, which is -4 (little endian stored), The next line shows the relocation entry,r.offs

Presumably many relocation webmaster also in sorrow move website site Content Editor Update problem, education is not much high, brain no ink how to build high-quality moving site content, light processing Baidu not included, deep processing, too time-consuming and efficient, original brain Shang. Today to share with you the expansion of high-quality moving site content skills, so that the relocation webmas

, the compilation is completed after the generation of intermediate code.2.3 AssemblyThe compiled intermediate code is generated by the Assembler module to generate machine instructions that the computer can recognize to manipulate the hardware facility to generate the target code (relocatable target code).2.4 LinksLink processing of various object codes and library files (*.lib files), resource files (*,REC) through the linker module to eventually generate *.exe files that can be executed.2.5

address in createremotethread. Because the standard loadliberarya/W is used to load the DLL, the DLL will be found in the target process using processexplorer. Wutil's trick is: the loader itself will load MH. pdll, so IAT in MH. pdll has been built. This is hard to say, that is, all the system APIs that need to be used get the meaning. The second is relocation. In the target process virtualallocex, a memory space of the same size as the local DLL is

The author previously needs to call the SQL query analyzer in a project and return the execution result through the command line. So the author adopted the DOS relocation technology to solve the problem. Now we will briefly explain how to use VC ++ for implementation.Use a command line to call the SQL AnalyzerThe isqlw utility (SQL query analyzer) allows you to enter Transact-SQL statements, system stored procedures, and script files. By setting short

Reposition Absolute Reference (absolute reference relocation)Or to undertake the previous program, in swap.c "int *bufp0 = buf[0];" Bufp0 is initialized to a global array address, so it needs to relocate, details by analyzing the target file you can know the runtime address of the BUF, *refptr = (unsigned) (ADDR (R.symbol) + *refptr)= (unsigned) (0x0804a014 + 0)= (unsigned) (0x0804a014)In the final executable target file, Reposition Absolute Reference

Problem Introduction:Linux elf files are very difficult to understand at first, some people may go to see "linkers and Loaders", this book is really good, but there is no detailed explanation of many details, especially from the assembly language perspective. I read this book a lot of places still do not understand, and then I read the IBM360 computer Assembler design document, which detailed the two times scanning assembler design principle, as well as the
