环境描述linux 5.6 安装Oracle 10.2.0.1.0
DBCA问题
1）DBCA图形化界面，出现乱码
测试环境，操作系统中文字符编码导致
export LANG=C
2）DBCA图形化点击，图形界面瞬间abort消失，留下如下信息
[[email protected] ~]$ dbca /u01/oracle/db_1/bin/dbca: line 158: 5412 Aborted
$JRE_DIR/bin/java -Dsun.java2d.font.DisableAlgorithmicStyles=true -DORACLE_HOME=$OH -DDISPLAY=$DISPLAY
-DJDBC_PROTOCOL=thin -mx128m -classpath $CLASSPATH oracle.sysman.assistants.dbca.Dbca $ARGUMENTS
--经过百度，主机名信息问题
[[email protected] ~]# hostname
localhost.localdomain
[[email protected] ~]$ cat /etc/hosts # Do not remove the following line,or varIoUs programs # that require network functionality will fail. 127.0.0.1 localhost.localdomain localhost ::1 localhost6.localdomain6 localhost6
--修改后
[[email protected] ~]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:0C:29:65:03:A7 inet addr:192.168.20.88 [[email protected] ~]# vi /etc/hosts 192.168.20.88 test [[email protected] ~]$ vi /etc/sysconfig/network HOSTNAME=test hostname test --重新登录oracle用户，重启图形化界面
3）DBCA过程，创建实例时，无法创建共享内存段
ORA-27125: unable to create shared memory segment #下面用root执行下面的命令，将dba组添加到系统内核中：使用AMM管理方式，共享内存段创建需要此设置，否则无法启动到Nomount状态 [[email protected] ~]# more /proc/sys/vm/hugetlb_shm_group 0 [[email protected] ~]# [[email protected] ~]# [[email protected] ~]# id oracle uid=1001(oracle) gid=1000(oinstall) groups=1000(oinstall),1001(dba),1002(oper) [[email protected] ~]# [[email protected] ~]# echo 1000 >/proc/sys/vm/hugetlb_shm_group vi /etc/sysctl.conf vm.hugetlb_shm_group = 1000 /sbin/sysctl -p
/sbin/sysctl -a
