在某些极端情况下,需要在linux 6上面安装Oracle 19C(没有通过官方认证),这里进行了一些测试,安装实施成功,主要问题记录如下:
系统信息

[root@ora11g ~]# more /etc/issue
Oracle Linux Server release 6.9
Kernel \r on an \m
[root@ora11g ~]# uname -r
4.1.12-61.1.28.el6uek.x86_64

[FATAL] [INS-30060] Check for group existence failed

通过./runInstaller -ignoreInternalDriverError解决
参考:Oracle 18c on RHEL 6.10 fail with “[FATAL] [INS-30060] Check for group existence failed.” (Doc ID 2464358.1)

安装完成之后,sqlplus启动报错

[oracle@ora11g ~]$ sqlplus -v
sqlplus: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /u02/app/oracle/product/19.2/db_1/lib/libclntsh.so.19.1)
sqlplus: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /u02/app/oracle/product/19.2/db_1/lib/libclntshcore.so.19.1)
sqlplus: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /u02/app/oracle/product/19.2/db_1/lib/libnnz19.so)

主要是由于19C要求glibc-2.14,但是该系统版本情况如下

[root@ora11g ~]# strings /lib64/libc.so.6 |grep GLIBC
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_PRIVATE

安装glibc-2.14

[root@ora11g ~]# wget http://ftp.gnu.org/gnu/glibc/glibc-2.14.tar.gz
[root@ora11g ~]# mv glibc-2.14.tar.gz /opt/software
[root@ora11g ~]# cd /opt/software
[root@ora11g software]# tar xf glibc-2.14.tar.gz
[root@ora11g software]# cd glibc-2.14
[root@ora11g glibc-2.14]# mkdir build
[root@ora11g glibc-2.14]# cd build
[root@ora11g build]# ../configure --prefix=/usr/local/glibc-2.14
[root@ora11g build]# make -j4
[root@ora11g build]# make install
[root@ora11g build]# cd /usr/local/glibc-2.14/lib
[root@ora11g lib]# cp libc-2.14.so /lib64/
[root@ora11g lib]# cd /lib64
[root@example lib64]# /sbin/sln libc-2.14.so /lib64/libc.so.6
[root@ora11g lib64]# strings /lib64/libc.so.6 |grep GLIBC
GLIBC_2.2.5
GLIBC_2.2.6
GLIBC_2.3
GLIBC_2.3.2
GLIBC_2.3.3
GLIBC_2.3.4
GLIBC_2.4
GLIBC_2.5
GLIBC_2.6
GLIBC_2.7
GLIBC_2.8
GLIBC_2.9
GLIBC_2.10
GLIBC_2.11
GLIBC_2.12
GLIBC_2.13
GLIBC_2.14
GLIBC_PRIVATE

sqlplus工作做正常
