MySQL Troubleshooting for the Obsessive Oracle DBA

One of my favorite customers had a problem. They had to load around 20G of data into a table on MySQL database. The data loaded fine, but when he tried to build few indexes on the database, he got a mysterious error: ERROR 1114 (HY000): The table ‘really_big_table’ is full. The error was mysterious because we had around 1.5T of free space on the disk. Also, if the customer created the indexes before loading the data there was no error.

EBS DBA: R12.1.2 Another Step for Automated Vanilla EBS Cloning

If you have tried to automate EBS cloning then you definitely know that you can’t get through without hacking and customizing the Oracle-provided Rapid Clone utility. One of the areas we should “hack” the code to make it running in batch scripts is the services startup bit. The problem is that by default straight after Rapid Clone is completed Oracle starts all the services on the Apps node and until now there wasn’t a way to change it.
