VCP modules can be implemented on the same instance where other modules like Order Management, Purchasing, Field Service etc are implemented. But, the regular practice is to use a distributed system. In a distributed environment we implement VCP on a separate instance (called the destination instance) and bring in the data required for VCP from another instance called the Source Instance. VCP Instance setup steps Create the source instance entry into VCP. A single VCP instance can plan for many source instances. Every source instance has a unique 'Instance Code' which we give as the entry while creating the 'Application Instances'. Functional Setup: Navigation - Service Supply Chain Administrator --> Admin --> Instances Important Fields: Instance Code -- Unique Source Instance Code Version -- Version of Source Instance. (Ex: R12.1) From Source to APS -- Database Link to get data from source ...

If the option does not exist, you can also create it with PUT. All PUT operations are local -- in other words, a PUT on the server affects only the server-side profile cache, and a PUT on the client affects only the client-side cache. By using PUT, you destroy the synchrony between server-side and client-side profile caches. As a result, we do not recommen...

 Overview ======== Here we look at how to write text into a file using the Linux cat command. The cat Command ================ Cat command's common usages is to print the content of a file onto the standard output stream. Other than that, the cat command allows us to write some texts into a file. The Syntax ========== Please look at the general syntax of the cat command: cat [OPTION] [FILE] Copy First, OPTION is a list of flags we can apply to modify the command’s printing behavior,  whereas FILE is a list of files we want the command to read. Making cat Read From stdin ========================== Let’s execute the cat command: cat Now try to enter some texts into the terminal: cat This is a appsolworld This is a appsolworld Once we are done, we can terminate the command by pressing CTRL+D. [demantra@dsiddem demantra]$ cat >> a appsolworld ^C [demantra@dsiddem demantra]$ cat a sfsfsfsd appsolworld [demantra@dsiddem demantra]$ cat > a this [demantra@dsiddem demantra]$ c...

  _FIX_CONTROL is a special hidden dynamic parameter which can be used to enable or disable certain bug fixes. This is typically used in the optimizer area to allow specific fixes to be turned on or off as some fixes can have a significant  effect on execution plans.  we are using the parameter _FIX_CONTROL to  enable or disable specific patches.  The syntax for using _FIX_CONTROL is: To enable: "_fix_control"='Bugno:ON'    (OR)   "_fix_control"="Bugno:1" To disable: "_fix_control"='Bugno:OFF'  (OR)   "_fix_control"="Bugno:0"   For _FIX_CONTROL to work, several conditions must be met:  The patch that is referenced must have the option to use _FIX_CONTROL.  Using _FIX_CONTROL can't be used to back out any patch.  The patch (usually an Optimizer patch)  has to be enabled to use the _FIX_CONTROL parameter. The patch must be installed and visible in the V$SYSTEM_FIX_CONTROL view.  To check this:  ...
