RedHat linux enterprise 5.7 RDAC Installation Details

First, copy the rdac-linux-09.03.0c05.0652-source.tar.gz software to the/tmp directory in linux (my version is redhat Linux enterprise 5.7.
2. decompress the software
Tar zxvfrdac-LINUX-09.03.0C05.0652-source.tar.gz
The decompressed directory is generated in the current directory and switched to the decompressed directory.
Cd linuxrdac-09.03.0C05.0652.
3. Many software packages are required to install RDAC (I installed the required software package for Oracle 10G under redhat Linux enterprise 5.7, which is listed below)
Software packages required for oracle10G
Compat-db-4.2.52-5.1.i386.rpm
Compat-gcc-34-3.4.6-4.i386.rpm
Compat-gcc-34-c ++-3.4.6-4. i386.rpm
Compat-libstdc ++-33-3.2.3-61.i386.rpm
Gcc-4.1.2-51.el5.i386.rpm
Glibc-2.5-65.i386.rpm
Glibc-devel-2.5-65.i386.rpm
Glibc-headers-2.5-65.i386.rpm
Kernel-headers-2.6.18-164.el5.i386.rpm
Libgomp-4.4.4-13.el5.i386.rpm
LibXp-1.0.0-8.1.el5.i386.rpm
Openmotif-2.3.1-5.el5_5.1.i386.rpm
Some packages that require kernel are prompted when installing RDAC
I simply installed all the software packages starting with kerne, as shown below:
Kernel-2.6.18-274.el5.i686.rpm
Kernel-debug-2.6.18-274.el5.i686.rpm
Kernel-debug-devel-2.6.18-274.el5.i686.rpm
Kernel-devel-2.6.18-274.el5.i686.rpm
Kernel-doc-2.6.18-274.el5.noarch.rpm
Kernel-headers-2.6.18-274.el5.i386.rpm
Kernel-PAE-2.6.18-274.el5.i686.rpm
Kernel-PAE-devel-2.6.18-274.el5.i686.rpm
Kernel-xen-2.6.18-274.el5.i686.rpm
Kernel-xen-devel-2.6.18-274.el5.i686.rpm

4. Install the tool below and switch to the directory after decompression
Make
After compilation, if no error is reported, it will pass. After installation
Make install
This process is slow and patient. If no error is reported, it will pass.
5. Go to the/boot directory
Execute the ls command
Find the file starting with mpp
Mpp-2.6.18-274.el5xen.img
6. Modify the file in/etc/grub. conf.
Vi/etc/grub. conf
Open it and check the default value. For example, my source file is as follows:
 
Default = 3
Timeout = 5
Splashimage = (hd0, 0)/grub/splash.xpm.gz
Hiddenmenu

Module/initrd-2.6.18-274.el5xen.img
In the file, the default value is the title value starting from 0.
Copy the content under the third title, modify the startup Item and put it at the end of the file, and modify default = 4
