Problem description: Recently, We need to export all the data in the test database and import it to Oracle locally installed in the Linux Virtual Machine. Since the disk space allocated to Linux was only 8 GB, at present, the remaining space is less than 500 mb, while the DMP file exported from the test database has more than 2 GB, which is obviously insufficient disk space. Solution: append the hard disk t

Recently implemented a project to use a domestic dual-machine hot-standby products, but in the database to do two-machine hot standby There are some problems, there is no way. Have to study it! After two days of research finally the problem was solved. Record problem-handling steps for later use and hopefully help people who need it.First,First introduce our environment: two servers + one storage + two dual

data disk of transaction systems is mainly caused by dirty Data Writing (maybe your situation is different from mine). Generally, IOPS is not high. This depends on the system. If IOPS is not enough, you can consider using SSD to increase IOPS, but the storage does not support SSD well. It is best to scatter ssd io in multiple storage fiber loops. 3) ORACLE's group commit is an automatic and default action. In fact, it cannot be optimized without optimization. 4) set the CACHE attribute for key

Hello everyone, I recently quit my job at home, so I had nothing to do. I wanted to create a ROM of an old model. As a result, win7 didn't catch a cold, so I couldn't do it. I wanted to build a dual-system, but I had no choice but to do it too, and it's complicated. You can only use virtual machines.

Working Group accidentally touches the virtual machine, is curious to install one to play. Later I heard that the database can be installed on the virtual machine, go home on the busy, and did not have a long time to succeed, and then my friend Xiao Li gave me a remote help, or no success. It's so bad that I lost it. But his help is that I understand The principle of PLSQ access to remote databases. After

There are three possible reasons for this situation. 1. Is the machine with Oracle installed NTFS? If yes, grant all bin permissions under \ ora81 to all users.(Otherwise, this error will be reported due to no permission to access the directory in the B/S structure) 2.

There are two ways to compute Oracle License: By number of users and number of CPUs. These are calculated by CPU as follows: License Number = The number of CPU cores * Core Factor One of the core Factor can refer to the official document Oracle Processor Core Factor. If Oracle is installed on VMware, is it also calculated in this way? In other words, is Oracle
