First contact with Oracle database and SUSE system experience

It took two days to build Oracle for the first time .....

It's been a lot of hard times.

So do some summing up

Summary, Experience:

because the installation is not successful yesterday, so today before the deployment, the first summed up the problems of yesterday, in advance to do some of the corresponding measures to avoid some unnecessary trouble

           

Let's start by describing the approximate process of yesterday:

Yesterday at the time of installation, first found the document on the Internet, and then began to deploy the Oracle operating environment on VMware SUSE11 at that time, the configuration provided by VMware is as follows: (processor 1p/1c memory 1G HDD 10G, etc. after the installation of the system, start to configure the network, Connect the virtual machine to the physical machine, and then configure the software source with a mirrored mirror on the physical machine to install the Lrzsz tool, and then transfer the installation package on the physical machine to the virtual machine via the Xshell tool to decompress, by referencing the documentation, to address some of the dependencies (packages) required before the Oracle installation, Create Oracle users and corresponding groups, create the directory required for Oracle installation and change the appropriate permissions, then configure the kernel parameters, configure the user, the environment variable is finally switched to the Oracle user, start the graphical installation program and then start error, error, error ...)

           

       oracle after the setup program started I'm not going to tell you. But there were a lot of problems just during the narrative process.

    

    

3) Instant no words ... Can only add a new disk, partition, the/MNT under the package to move out, mount, and then restore the package back, repeat the previous action configuration software source .... Wait

4) Then it is in the configuration kernel parameters when the value does not know how to give the corresponding value, check data, solve

    

    

    

    

plainly, yesterday all day to do these meaningless things, are dealing with the wrong, all kinds of wonderful problems (unreasonable plan, confusion of thoughts )

so this morning before the deployment, a good review of yesterday's problem, did the following measures:

1) First is the configuration one-time to the full: processor 1p/1c memory 2G HDD

    

    

4) Follow the same steps, each completed a link, the test is not a problem after a snapshot (such as the dependency resolved , the kernel parameters resolved ... etc.)

Since there is no worries, that would like to how to come, there is plenty of time to let me find information, to analyze the configuration of the files in the meaning of each parameter.

    

     General after Oracle is installed, Oracle default processes is 150, sometimes not enough, need to change the process to the "font-family: ' New song body ' style="; font-size : 13px;font-weight:bold;line-height:1.5; " So, it's not too early to go to the final step or not to be happy ... It's a bad feeling to fall from a high.

     initorcl.ora the problem of this file, finally solved the history file, Take a good look at the specific steps and the meaning of the relevant parameters!  

            

Note: The above content is only I described the two days to build Oracle experience, because the first contact and there is no deep insight, not detailed, a later time I will study carefully, so the wrong place please understand ...
