EPM Registry Initialization Fails

The EPM Registry initialization fails in the BIDomain domain. Oracle Fusion General Ledger and Oracle Fusion Customer Relationship Management (CRM) code running within the FinancialsDomain and CRMDomain domains, respectively, has direct integration with the EPM Registry API and consumes EPM Security Component, which also tightly integrates with the EPM Registry API. When EPM Registry initialization fails, it greatly impacts communication with downstream EPM products in the BI domain.

This solutions came to my mind when i was asked to allow registrar to create student certificates online when they were using the school's local website - similar to TISS certificate generator - i used the free FPDF library which is a PHP class which allows to generate PDF files with pure PHP - the aim is to allow the registrar of school to be able to take the student’s id and course id and generate the student's certificate for a course - the main aim is to show how the class is used in a simple and easy way for use in a small scale - There are two files.

Missing special german characters on an english keyboard

Usually I am coding with English (US) keyboard layout, because the special characters are arranged in a better way as with german layout. But if I want to write messages in german, I am missing the special german chars (ä,ö,ü,ß). I don't want to switch languages everytime, because I am used to have the "y" key in the first row. I want to have an easy way to use special german chars like the key longpress on an Android device.

Enabling temporary wireless access

Problem 3. There was couple of times that our neighbor asked to use our internet (they ran out of their own capacity for downloading). So we decided to let them, but even though we didn’t give them the password his laptop kind of saved it or I think I forgot to look for this check box which asks If I want this network to be saved or not. Well after that he started to use our internet more and more and we had to all the time increase our limit.
