Ok, after having some time for playing around I decided to try a 12c installation on debian wheezy.
install mandatory packages
apt-get install binutils autoconf automake bzip2 gcc less libc6-dev make libstdc++5 unzip zlibc build-essential libaio1
create some links
Some libs are expected in other directories, we need to change that
ln -s /usr/lib/x86_64-linux-gnu/ /usr/lib64
x-terminal
I chose fluxbox but you can also take anything else like xterm, gnome, kde….
apt-get install fluxbox
prepare user and groups
groupadd oinstall
groupadd dba
useradd oracle -m -d /home/oracle -g oinstall -G dba -s /bin/bash
passwd oracle
check environment
there are several kernel parametersw that have to be changed to succesfully install the database, here is a script that helps you to determine them
echo "sem: ";echo "min 250 32000 100 128"; echo "is " `cat /proc/sys/kernel/sem`; echo; \
echo "shmall: ";echo "min 2097152"; echo "is " `cat /proc/sys/kernel/shmall`; echo; \
echo "shmmax - should be able to hold the SGA - max 4G-1byte: ";echo "is " `cat /proc/sys/kernel/shmmax`; echo; \
echo "shmmni: ";echo "min 4096"; echo "is " `cat /proc/sys/kernel/shmmni`; echo; \
echo "file-max: ";echo "min 6815744"; echo "is " `cat /proc/sys/fs/file-max`; echo; \
echo "ip_local_port_range: ";echo "min/max 9000 65500"; echo "is " `cat /proc/sys/net/ipv4/ip_local_port_range`; echo; \
echo "rmem_default: ";echo "min 262144"; echo "is " `cat /proc/sys/net/core/rmem_default`; echo; \
echo "rmem_max: ";echo "min 4194304"; echo "is " `cat /proc/sys/net/core/rmem_max`; echo; \
echo "wmem_default: ";echo "min 262144"; echo "is " `cat /proc/sys/net/core/wmem_default`; echo; \
echo "wmem_max: ";echo "min 1048576"; echo "is " `cat /proc/sys/net/core/wmem_max`; echo; \
echo "aio-max-nr: ";echo "max 1048576"; echo "is " `cat /proc/sys/fs/aio-max-nr`; echo;
change necessary parameters
you have just to change the parameters that don't fit, but feel free to set them all to the minimum with this script
echo "kernel.sem = 250 32000 100 128" >> /etc/sysctl.conf
echo "kernel.shmall = 2097152" >> /etc/sysctl.conf
# !!!! needs to fit YOUR SGA (=main memory for database, be sure to have enough ram for PGA etc.)!!!!
echo "kernel.shmmax = 1200000000" >> /etc/sysctl.conf
#echo "kernel.shmmni = 4096" >> /etc/sysctl.conf
echo "fs.file-max = 6815744" >> /etc/sysctl.conf
#echo "net.ipv4.ip_local_port_range = 1024 65000" >> /etc/sysctl.conf
echo "net.core.rmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.rmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.rmem_max = 4194304" >> /etc/sysctl.conf
echo "net.core.wmem_default = 262144" >> /etc/sysctl.conf
echo "net.core.wmem_max = 1048576" >> /etc/sysctl.conf
echo "fs.aio-max-nr = 1048576" >> /etc/sysctl.conf
change some limits
also some limits have to be set
echo "oracle soft nproc 2047" >> /etc/security/limits.conf
echo "oracle hard nproc 16384" >> /etc/security/limits.conf
echo "oracle soft nofile 1024" >> /etc/security/limits.conf
echo "oracle hard nofile 65536" >> /etc/security/limits.conf
create directories
I prefer to separate software, database files and recovery files so i put them under /opt/oracle (mountpoint) in different directories
mkdir -p /opt/oracle/app/oracle/opt/oracle
mkdir -p /opt/oracle/oradata
mkdir -p /opt/oracle/flash_recovery_area
chown -R oracle:oinstall /opt/oracle
chmod -R 775
These steps prevent errors when the installer links some libraries
ln -s /usr/bin/awk /bin/awk
ln -s /usr/bin/basename /bin/basename
finish preparations
reboot
after unzipping the installation files add some tweaks...
Some makefiles need manual tweaking because they can't find required libs beause of some environment issues
sed -i 's/\$(PLSHPROF_LINKLINE)/\$(PLSHPROF_LINKLINE) -lons/g' /opt/oracle/app/oracle/product/12.1.0/dbhome_1/rdbms/lib/ins_rdbms.mk
sed -i 's/\$(RMAN_LINKLINE)/\$(RMAN_LINKLINE) -lons/g' /opt/oracle/app/oracle/product/12.1.0/dbhome_1/rdbms/lib/ins_rdbms.mk
sed -i 's/\$(TG4PWD_LINKLINE)/\$(TG4PWD_LINKLINE) -lnnz12/g' /opt/oracle/app/oracle/product/12.1.0/dbhome_1/rdbms/lib/ins_rdbms.mk
installer
su oracle
/pathtoinstallfileshere/database/runInstaller -ignoreSysPrereqs
The installer should guide you through each step in simple and advanced mode. When the requirements are checked you can savely bypass the warnings, because not everything can be checked on an unsupported ;-) environment.
!!!I really want to keep this up-to-date so please send me a note if i missed something or something is easier to handle than i did it!!!
Errors that can happen and how to bypass them
Could not retrieve local nodename
that happens if the hostname is not in your /etc/hosts file, just insert it there as localhost and it should work
java exception when calling the installer
happened at my side because I installed it over vnc This should help:
xhost localhost
Error in invoking target 'install' of makefile ins_ctx.mk
seems to be a problem with a newer? glibc version in the make.log file you should find something like
warning: libstdc++.so.5, needed by /u01/app/oracle/product/11.2.0/dbhome_1/ctx/lib//libsc_fa.so, not found
simply install libstdc++5 apt-get install libstdc++5
