finishes processing the Language Pack, it will display a menu for you to customize Live CD. Select the first item and you will be new. Here you can add or delete software packages and process dependencies between them. Select the second item and you will enter a terminal. This is a chrooted environment that can be customized for Live CD. Here, you can install software (which seems to be prepared by someone who prefers command line operations), or start gconf-editer here to modify the desktop an

Resource)GRD1.GRD (Global Resource Directory) can be seen as an internal database that records the distribution of each chunk between clusters in each instance of the SGA. Each instance of GRD in the SGA becomes a complete grd. The usage information for this resource on all nodes is recorded on the RAC's master node. The usage information for each node is recorded on this node.Drm1.DRM (Dynamic Resource Management), when a non-master node's resources are frequently visited, the node can be prom
In the RAC environment, Oracle uses GRD (Global Resource Service) to record the Resource information of each RAC node. The Resource information of each RAC node is recorded by using GCS (Global Cache Service) and GES (Global Enqueue Service) these two services are managed.
In RAC, each node has its own SGA and buffer cache. To ensure Cache resource consistency and improve performance, GCS and GES specify an instance in RAC to manage the Cache, this node is the Resource Master.

Because my Ubuntu system has installed a lot of software and modified many settings, I don't want to refresh the system for a long time, so I thought of how to generate an image for the existing system, in this way, even if you want to reinstall the system, you can use a custom image to directly install the system.
There are a lot of software on the network, but I use the remaster sys most easily. As shown in the following figure, step by step after
