Label:Personal feeling the switch from the Windows platform to the Linux platform is an inappropriate place to use the debugger. Because under the Windows debugger basically relies on the shortcut key and the image interface to complete the operation, even if is WinDbg this kind of pseudo command line tool, the command is also very simple to remember.GDB, by contrast, is very complicated, and some of the GDB articles found on the web are often made with no eggs, so open a post to keep track of t

Verifying the installation environmentIt is necessary to use the CVU tool before installation to verify that the current environment has the conditions for setting up an Oracle RAC. By using this tool, you can also find configuration issues before you perform a specific installation. Execute the following command to check the installation environment:./runcluvfy.sh Stage-pre Crsinst-n Rhel1,rhel2-fixup-verbose......Check:membership of user "grid" in Group "DBA"Node Name User Exists Group Exists

Utility functionsDECODEThe syntax is as follows:DECODE (value, IF1, Then1, If2,then2,if3,then3, ... else) value represents any column of any type of a table or any result that is computed. When each value is tested, if value is the result of the If1,decode function is then1, and if value equals If2,decode The result of the function is then2; In fact, multiple if/then pairs can be given.　　If the value result is not equal to any given pairing, the Decod

Label:As far as I know, Apex 4.x does not provide an editable interactive reporting component. This requires our manual implementation. In fact, this is not very complicated, just a few simple steps.1. Create a interactive report according to the wizard. The query statement can be as follows.

TracertCommand asRoutingThe tracing and diagnosis utility has this command in DOS and Unix systems. It sends an Internet Control Message Protocol (ICMP) echo request and an echo response message, generate command line report output for each vro to track the path. This program is one of the necessary TCP/IP tools for network management. It is often used to test network connectivity and determine the fault location. Therefore, it is necessary for us to
