Oracle 19c 安装的问题解决 - DBT-00006

在安装 Oracle 19c RPM 时，依托 18c 的安装基础，非常顺利的可以完成安装。

请先参考：

我的服务器版本：

[oracle@sdb0 ~]$ cat /etc/redhat-release

CentOS release 6.8 (Final)

[oracle@sdb0 ~]$ uname -a

Linux sdb0 2.6.32-642.6.2.el6.x86_64 #1 SMP Wed Oct 26 06:52:09 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

以 root 身份：

rpm -ivh oracle-database-ee-19c-1.0-1.x86_64.rpm

Preparing...
1:oracle-database-ee-19c ############ [100%]
[INFO] Executing post installation scripts...
[INFO] Oracle home installed successfully and ready to be configured.
To configure a sample Oracle Database you can execute the following service configuration script as root: /etc/init.d/oracledb_ORCLCDB-19c configure

可是在运行创建数据库的脚本时，遇到错误。

以下这个脚本用于初始化一个数据库：

/etc/init.d/oracledb_ORCLCDB-19c configure

遇到的错误是 DBT-00006 ：

[root@sdb2 ~]# /etc/init.d/oracledb_ORCLCDB-19c configure
Configuring Oracle Database ORCLCDB.
[FATAL] [INS-00001] Unknown irrecoverable error

ACTION: Refer to the logs or contact Oracle Support Services
SUMMARY:

Database configuration failed.

DBT-0006 ,提示不能创建日志目录，不要被单纯的字面意思所误导。

当尝试使用任何 Oracle 的执行文件时，发现一个错误暴露出来，原来是 GLIBC 版本过低，我的版本是 2.12 ，数据库需要 2.14：

[oracle@sdb2 ~]$ sqlplus / as sysdba
sqlplus: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /opt/oracle/product/19c/dbhome_1/lib/libclntsh.so.19.1)
sqlplus: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /opt/oracle/product/19c/dbhome_1/lib/libclntshcore.so.19.1)
sqlplus: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by /opt/oracle/product/19c/dbhome_1/lib/libnnz19.so)

开始要将 glibc 从 2.12 更新到 2.14，需要解决相关依赖问题，至少需要:

glibc-2.14.1-6.x86_64.rpm

glibc-common-2.14.1-6.x86_64.rpm

glibc-devel-2.14.1-6.x86_64.rpm

glibc-headers-2.14.1-6.x86_64.rpm

同步更新。

为我的老服务器找到了这几个包：

ftp://ftp.pbone.net/mirror/archive.fedoraproject.org/fedora/linux/updates/15/x86_64/

wget ftp://ftp.pbone.net/mirror/archive.fedoraproject.org/fedora/linux/updates/15/x86_64/glibc-2.14.1-6.x86_64.rpm
wget ftp://ftp.pbone.net/mirror/archive.fedoraproject.org/fedora/linux/updates/15/x86_64/glibc-common-2.14.1-6.x86_64.rpm
wget ftp://ftp.pbone.net/mirror/archive.fedoraproject.org/fedora/linux/updates/15/x86_64/glibc-devel-2.14.1-6.x86_64.rpm
wget ftp://ftp.pbone.net/mirror/archive.fedoraproject.org/fedora/linux/updates/15/x86_64/glibc-headers-2.14.1-6.x86_64.rpm

然后安装：

[root@sdb2 ~]# rpm -Fhv glibc*rpm
warning: glibc-2.14.1-6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 069c8460: NOKEY

########################################### [ 50%]
3:glibc-headers ########################################### [ 75%]
4:glibc-devel ########################################### [100%]

接下来再运行Oracle的DBCA或者安装程序，就一切正常了：

[root@sdb2 ~]# su - oracle
[oracle@sdb2 ~]$ sqlplus / as sysdba

SQL*Plus: Release 19.0.0.0.0 - Production on Wed Nov 28 14:36:02 2018

建议按照新版本数据库是，相应的更新操作系统。
