CentOS7.2安装Oracle11g

图片说明

如附件,执行./runInstaller后,提示有配置不过关,如何进行查看和配置。查看网上资料,root用户下执行xhost,然后到oracle执行export DISPLAY=:00,没有解决。

CentOS7.2安装Oracle11g,报错[INS-32038] ?
[FATAL] [INS-32038] The operating system group specified for central inventory (oraInventory) ownership is invalid. CAUSE: User performing installation is not a member of the operating system group specified for central inventory(oraInventory) ownership. ACTION: Specify an operating system group that the installing user is a member of. All the members of this operating system group will have write permission to the central inventory directory (oraInventory). A log of this session is currently saved as: /tmp/OraInstall2019-02-18_09-46-24PM/installActions2019-02-18_09-46-24PM.log. Oracle recommends that if you want to keep this log, you should move it from the temporary location to a more permanent location. [oraclenewone@tony01数据库]$ [FATAL] [ines -32038]为中央库存(oraInventory)所有权指定的操作系统组无效。 原因:执行安装的用户不是为中央库存(oraInventory)所有权指定的操作系统组的成员。 操作:指定安装用户所属的操作系统组。这个操作系统组的所有成员都将具有到中央目录目录(oraInventory)的写权限。 这个权限如何赋予才能通过,请教大神们。

关于Linux下Oracle10g 中文字段的问题
系统我用的是CentOS6.7 装的ORACLE10g 想把windows下的oracle数据移植到linux上, 其它都一切正常,但是最后在导入的时候报错了,我看了下,报错的地方就是使用了中文字段的表,在create 的时候报错:比如这样的表 create table aaa (id int, name varchar2 , 注册日期 datetime) 这种情况的表。 期间我重装了一次10g 然后把10g里面的系统设置成了中国的,之后startup的时候 出一堆??? 然后重新导入备份的数据 还是报错上面的那个错 所以问下各位高手,这种情况如何处理?
oracle11g配置监听(centos7下)
按照一般流程配置完成了,我先在1号终端启动监听lsnrctl start,再打开另一个终端,sqlplus /nolog打开服务器,再输入 conn sys@orcl001 as sysdba,想连接,但是出现提示: TNS:listener does not currently know of service requested in connect descriptor(侦听器目前不知道连接中请求的服务描述符)!! 于是我又 alter system register;(实例注册),又提示 Not connected(没有连接)!! 我又到1号终端,查看监听状态,提示The listener supports no services(侦听器不支持服务)!!!,我又重启监听和服务器,还是不行,还是以上提示!!!! 求大神~!帮助~!! 一下是配置文件: listener.ora SID_LIST_LISTENER = (SID_LIST = (SID_DESC= (GLOBAL_DBNAME =ORCL) (ORACLE_HOME =:/data/oracle/product/11.2.0/db_1) (SID_NAME = ORCL) ) ) LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) ) tnsnames.ora ORCL001 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = orcl11g)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) ) ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) )
谁有linux版oracle12c的漏洞补丁包
centos7安装的oracle12c版本的 linuxamd64_12102_database_1of2.zip 经过绿盟软件扫描后出现大量的oracle安全组件漏洞。 求好心人发个资源给我; 或者有别的解决方案望告知。
