Install the 32-bit oracle software in 64-bit linux

Install the 32-bit oracle software in 64-bit linux
In some cases, sometimes we need to install 32 oracle software on a 64-bit system (for example, the customer's abnormal requirements ). Although theoretically, this method is feasible, but in the actual installation process is often a hundred errors, in order to avoid unnecessary errors, but also to facilitate future work search, record the installation process.
In this example, the redhat4-64-bit operating system and oracle 10 Gb are used as the database. During the installation process, only the smallest installation package is used to detect as many problems as possible. Because the problem mainly occurs in the installation and compatibility of software packages, other aspects of the installation process are not involved.


First, configure yum to use a local CD as the source and install the 32-bit and 64-bit software simultaneously:


[Root @ localhost ~] # Cat/etc/yum. conf
[Main]
Cachedir =/var/cache/yum/$ basearch/$ releasever
Keepcache = 0
Debuglevel = 2
Logfile =/var/log/yum. log
Exactarch = 1
Obsoletes = 1
Gpgcheck = 0
Plugins = 1
Installonly_limit = 3


# This is the default, if you make this bigger yum won't see if the metadata
# Is newer on the remote and so you'll "gain" the bandwidth of not having
# Download the new metadata and "pay" for it by yum not having correct
# Information.
# It is esp. important, to have correct metadata, for distributions like
# Fedora which don't keep old packages around. If you don't like this checking
# Interupting your command line usage, it's much better to have something
# Manually check the metadata once an hour (yum-updatesd will do this ).
# Metadata_expire = 90 m


# Put your repos here or in separate files named file. repo
# In/etc/yum. repos. d


# Install both 32 and 64
Multilib_policy = all


In the actual operation process, the yum effect is not obvious due to source issues.


Install the corresponding software package according to the official oracle documents (during the actual installation process, only 32-bit packages are installed, and others are not (n mark ),)


Binutils-2.15.92.0.2-10.EL4 n
Compat-db-4.1.25-9
Control-center-2.8.0-12 n
Gcc-3.4.3-9.EL4 n
Gcc-c ++-3.4.3-9. EL4 n
Glibc-2.3.4-2
Glibc-common-2.3.4-2 n
Gnome-libs-1.4.1.2.90-44.1 32-bit installation is more difficult, but still installed
Libstdc ++-3.4.3-9. EL4
Libstdc +-devel-3.4.3-9.EL4
Make-3.80-5 n
Pdksh-5.2.14-30 n
Sysstat-5.0.5-1 n
Xscreensaver-4.18-5.rhel4.2 n


Start the installation interface is, package libXp errors, in redhat4 can install xorg-x11-deprecated-libs to solve.


The official team did not point out that the libaio and libaio-devel packages should be installed in redhat4. If the package does not comply with the report, it will not pass the test.


The following error is reported during installation.

Conclusion: It is not recommended to install 32-bit oracle on 64-bit linux.
Can 32-bit oracle databases be installed in 64-bit Linux?

Yes

All hardware devices are backward compatible.

64-bit can be installed with 32-bit

But 32-bit cannot be installed 64

However, there may be a lack of runtime libraries, which is troublesome,

In 32-bit linux, can I install 64-bit oracle?

Certainly not. 32-bit: 1 byte = 32bit, 64-bit 1 byte = 64bit, two differences, fundamentally differentiate the program, so it cannot support 64-bit on 32-bit, and vice versa.
