Oracle EBS R12.1.1 on Oracle Linux64 5.7
依赖包仅选了oracle-validated-1.1.0-14.el5，未作其他依赖包验证。
1. 安装到最后一步进行验证时，所有http有关的服务都失败
1.1 运行adapcctl.sh status发现HTTP_Server没起来
-bash-3.2$ ./adapcctl.sh status
You are running adapcctl.sh version 120.7.12010000.2

1.2 尝试手动启动时，报了个错，然后HTTP_Server还是启动失败
-bash-3.2$ ./adapcctl.sh start
You are running adapcctl.sh version 120.7.12010000.2

1.3 根据手动重起HTTP_Server的信息检查log，发现如下关键信息（未找到）：
tail /u01/r12dev/inst/apps/r12dev_r12dev/logs/ora/10.1.3/opmn/HTTP_Server~1.log
/u01/r12dev/apps/tech_st/10.1.3/Apache/Apache/bin/httpd: error while loading shared libraries: libdb.so.2: cannot open shared object file: No such file or directory
1.4 解决方法，安装gdbm包并做两个符号链接：
[root@r12dev r12dev]# yum install gdbm
[root@r12dev r12dev]# ln -s /usr/lib64/libgdbm.so.2.0.0 /usr/lib64/libdb.so.2
[root@r12dev r12dev]# ln -s /usr/lib/libgdbm.so.2.0.0 /usr/lib/libdb.so.2
