    sysstat-10.1.5-1.el7(x86_64)

    2报错:yum源

    说明:端口不通,提交网络人员配置交换机

    #报错解决思路:

    #Yum安装,提示IP +PORT不通,使用telnet命令(远程节点telnet包上传,解压),提示路由问题

    [root@fs-3z3-vm0393 ~]# yum install -y binutils

    http://10.135.100.100/centos7.4/repodata/repomd.xml: [Errno 14] curl#7 - "Failed connect to 10.135.100.100:80; No route to host"

    Trying other mirror.

    #查询yum源

    name=Test_Env_yum_server

    baseurl=http://10.135.100.100/centos7.4

    enabled=1

    gpgcheck=0

    #使用telnet

    #传输介质:连接Yum源IP地址,搜索TEL相关rpm软件包,上传服务器,解压后

    #路由端口的问题!!!

    [root@fs-3z3-vm0393 ~]# telnet 10.135.100.100 80

    #匹配MOS 12.2 DBCA不符合ORA-15173Doc ID 2320091.1

    恢复pdb备份片时发生DBCA错误这是具有一个PDBCDB数据库,对于这种情况,建议在使用asm时使用OMF  ,退出安装,勾选OMF功能

    #创建操作系统密码文件,报错

    三、PDB配置

    1日志格式化

    alter database add logfile thread 1 group 22('+DATA','+DATA') size 512m;

    alter database add logfile thread 1 group 23('+DATA','+DATA') size 512m;

    alter database add logfile thread 1 group 25('+DATA','+DATA') size 512m;

    alter database add logfile thread 2 group 31('+DATA','+DATA') size 512m;

    alter database add logfile thread 2 group 32('+DATA','+DATA') size 512m;

    alter database add logfile thread 2 group 33('+DATA','+DATA') size 512m;

    alter database add logfile thread 2 group 34('+DATA','+DATA') size 512m;

    SQL>  alter system archive log current;

    SQL> alter system checkpoint;

    2tnsnames.ora文件配置
