【Database 12c】手动创建CDB Container Database容器数据库

手动建库几乎是每个DBA都需要掌握的技能,而Database 12c中手动创建Container Database容器数据库的过程是如何的呢?

目前12c创建容器数据库Container Database和普通Database存在一点点小的区别,需要指定enable pluggable database,已创建的数据库目前无法转换为容器数据库。

创建必要的目录

mkdir -p /stage/oradata
mkdir -p /stage/fr
mkdir -p /u01/app/oracle/admin/MACLEANCDB/adump

我们创建 实例初始化文件,并创建DB:

 

 

1、 INIT.ORA

2、 创建密码文件

 

 

oracle@localhost:~$ /u01/app/oracle/product/12.1.0/dbhome_1/bin/orapwd file=/u01/app/oracle/product/12.1.0/dbhome_1/dbs/orapwMACLEANCDB force=y extended=y

Enter password for SYS:

 

 

3、 正式创建DB

 

 

oracle@localhost:~$ export ORACLE_SID=MACLEANCDB
oracle@localhost:~$ sqlplus / as sysdba

SQL> startup nomount pfile='init.ora';
ORACLE instance started.

Total System Global Area 1018830848 bytes

enable pluggable database;

Database created.

set linesize 2048;
column ctl_files NEW_VALUE ctl_files;
select concat('control_files=''', concat(replace(value, ', ', ''','''), '''')) ctl_files from v$parameter where name ='control_files';
host echo &ctl_files >> /u01/app/oracle/admin/MACLEANCDB/scripts/init.ora;
spool off

将控制文件信息写入到中==》 echo &ctl_files >> /u01/app/oracle/admin/MACLEANCDB/scripts/init.ora;

 

 

4、创建默认使用的USERS表空间

 

SQL> CREATE SMALLFILE TABLESPACE "USERS" LOGGING  DATAFILE  SIZE 5M AUTOEXTEND ON NEXT  1280K MAXSIZE UNLIMITED  EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT  AUTO;

Tablespace created.

SQL> ALTER DATABASE DEFAULT TABLESPACE "USERS";

Database altered.

 

 

 

5、 执行必要的数据字典创建脚本

 

 

 

alter session set "_oracle_script"=true;
alter pluggable database pdb$seed close;
alter pluggable database pdb$seed open;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catalog /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/catalog.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catblock /u01/a
pp/oracle/product/12.1.0/dbhome_1/rdbms/admin/catblock.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catproc /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/catproc.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b catoctk /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/catoctk.sql;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b owminst /u01/ap
p/oracle/product/12.1.0/dbhome_1/rdbms/admin/owminst.plb;
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b pupbld -u SYSTE
M/&&systemPassword /u01/app/oracle/product/12.1.0/dbhome_1/sqlplus/admin/pupbld.sql;
connect "SYSTEM"/"&&systemPassword"
set echo on
spool /u01/app/oracle/admin/MACLEANCDB/scripts/sqlPlusHelp.log append
host perl /u01/app/oracle/product/12.1.0/dbhome_1/rdbms/admin/catcon.pl -l /u01/app/oracle/admin/MACLEANCDB/scripts -b hlpbld -u SYSTE
M/&&systemPassword -a 1  /u01/app/oracle/product/12.1.0/dbhome_1/sqlplus/admin/help/hlpbld.sql 1helpus.sql;
@/u01/app/oracle/product/12.1.0/dbhome_1/sqlplus/admin/help/hlpbld.sql helpus.sql;

 

 

 

6、 创建一个PDB

 

 

cp init.ora  /u01/app/oracle/product/12.1.0/dbhome_1/dbs/initMACLEANCDB.ora 

startup force;

CREATE PLUGGABLE DATABASE MACLEANCDB ADMIN USER MACadmin IDENTIFIED BY oracle
 FILE_NAME_CONVERT=(
  '/stage/oradata/MACLEANCDB/DC36ED41771D435CE0430100007FA00B/datafile/o1_mf_system_8rns0lxf_.dbf', '/stage/oradata/PDB1/datafile/system01.clone',
  '/stage/oradata/MACLEANCDB/DC36ED41771D435CE0430100007FA00B/datafile/o1_mf_sysaux_8rns13dk_.dbf', '/stage/oradata/PDB1/datafile/sysaux1.dbf.clone',
  '/stage/oradata/MACLEANCDB/DC36ED41771D435CE0430100007FA00B/datafile/o1_mf_temp_8rns1d89_.tmp', '/stage/oradata/PDB1/datafile/temp1.tmp.clone'
  )
 STORAGE UNLIMITED;

将在版本11.2之后废弃或不再支持的特性

12c是Oracle未来最重量级的数据库产品,每个新版本的到来都会带来吐故纳新,例如9i的sqlplusw、10g的isqlplus均在其后续版本中废弃;12c中将被废弃或不支持的特性,例如:Database Control DBconsole、OCFS on Windows、CSSCAN、CSALTER、cursor_sharing = ‘SIMILAR’、Oracle Net Connection Pooling feature。  为了照顾旧应用的兼容性,看来在12c中暂时不会彻底废掉RBO。

更多信息可以参考以下NOTE:

12c分页查询特性FETCH FIRST ROWS,OFFSET ROWS FETCH NEXT ROW LIMIT Clause子句

Database 12c的FETCH FIRST ROWS特性可以简化老版本中ROW_NUM()或ROWNUM的分页排序写法, 大幅节约开发花在分页查询语句上的时间。

row-limiting子句用以限制某个查询返回的行数

  • 可以通过FETCH FIRST/NEXT关键字指定返回结果的行数
  • 可以通过PERCENT关键字指定返回结果的行数比例
  • 可以通过OFFSET关键字指定返回从结果集中的某一行之后行数

12c row-limiting子句对于排序数据限制返回行今后会广泛使用(MySQL上早就有的特性,MySQL开发该特性可能是特别考虑到对于网站分页查询的简化),也可以被称作Top-N查询。

 

 
示意图:

 

SQL Row-Limiting Clause Examples
我们这里来对比老的ROWNUM写法等价的FETCH ROWS写法的实际性能对比:

create table larget tablespace users as select rownum t1, rpad('M',99,'A') t2, rpad('M',99,'A') t3, rpad('M',99,'A') t4 from dual connect by level<=99999;
SQL> create index pk_ind on larget(t1) tablespace users;
Index created.
select llv.* from 
(
select rownum rn, ll.* from
(select /*+ index( larget pk_ind */ *  from larget where t1 is not null order by t1 ) ll
where rownum<=20) llv 
where 
llv.rn>=1;
20 rows selected.

从以上的2个演示对比,可以看到2种写法实际消耗逻辑读数目是类似的;即12c 中FETCH FIRST ROWS,OFFSET ROWS FETCH NEXT的写法在实际性能上并不比传统的rownum写法来的效率低。 但是可以看到CBO在评估fetch rows执行计划的成本时其 TABLE ACCESS BY INDEX ROWID成本要比rownum写法高出不少,这似乎是由于不同的基数计算导致的。

【12c新特性】dbms_stats report_gather_auto_stats统计信息报告特性

版本12c中引入了dbms_stats 的一系列report_*  函数,用以在收集统计信息前 向用户汇报预备将执行的统计对象和统计情况。

 

例如report_gather_auto_stats

 

function report_gather_auto_stats (
detail_level varchar2 default ‘TYPICAL’,
format varchar2 default ‘TEXT’)
return clob;

— This procedure runs auto stats gathering job in reporting mode. That is,
— stats are not actually collected, but all the objects that will be
— affected when auto stats gathering is invoked are reported.
— The detail level for the report is defined by the detail_level
— input parameter. Please see the comments for report_single_stats_operation
— on possible values for detail_level and format.

 

具体使用:

 

SQL> variable c clob;
SQL> exec :c:=dbms_stats.report_gather_auto_stats();

PL/SQL procedure successfully completed.

SQL> set long 999

 

SQL> print :c;

Oracle Enterprise Manager 12c 新特性:实时Real-Time Addm

在Oracle Enterprise Manager 12c中引入了Real-Time addm的新特性。 DBA可以直接从EM界面上启动实时ADDM(Automatic Database Diagnostic Monitor )信息收集, 也叫做Emergency ADDM。

 

Emergency ADDM adds performance diagnostics for databases suffering from severe performance problems. Real-time ADDM. You can connect to the database and investigate what is going on when you cannot connect to the database because it is hanging on

 

 

登录EM 12c后Target -> Database -> 选择指定的数据库 -> Performance -> Real-Time Addm:

 

 

进入”Real-Time ADDM”后点选start按钮,第一次使用会出现”Required PL/SQL package not installed. Use the link below to deploy the package. The error message from the server is:Package dbsnmp.prvt_eaddm is not found” 的错误:

 

 

使用Real-Time Addm要求预安装dbsnmp.prvt_eaddm包,点选下方的PL/SQL Package Deployment链接,进入Package Deployment页面,选择合适的身份认证,并install。

 

 

进入Job Run: DATABASE MANAGEMENT PL/SQL DEPLOYMENT JOB页面等待作业完成。

以测试为目的登录数据库并运行以下消耗CPU的SQL语句(不要用在生产库!):

 

 select count(1) from obj$,obj$,obj$;

 

回到”Real-Time ADDM”页面再次点击start , 等待一段时间后会自动stop,如下图:

 

 

Real-Time Addm有所发现,这里的Number of finding =1 ,点击Findings 可以看到Prority、Performance Impact、Finding Details等信息:

 

 

当出现服务进程hang的情况,例如进程因”enq: TM contention”  队列锁而长久等待,则可以从hang data栏获取hang analysis Final Blocker 和 blocking session的信息, 找出阻塞的源头:

 

 

 

 

上图中列出了Blocker chains ,一定程度上可以替代hanganalyze dump。

statistics栏给出了实例的一些属性和近期的系统度量system metrics:

 

 

Real-Time Addm可以帮助我们快速定位性能和挂起hang问题,而且给出初步的分析,这要比我们使用脚本一步步查来的快捷多了。

快速部署Enterprise Manager Cloud Control 12c(12.1) Agent

<OEL 5上快速部署Enterprise Manager Cloud Control 12c(12.1)>中我介绍了如何安装配置Oracle Enterprise Manager Cloud Control 12c(12.1) Server ,我们知道光有EM Server而不部署Agent是无法发挥其管理特性的。

接下来我们会再次通过实践了解Em 12c(12.1)中部署Agent代理程序的过程,整个过程和10g/11g Grid Control中的Deploy Agent有较大的区别。

 

这里我们要注意一点,OMS 12c(12.1) 只能和12.1 的Agent 代理程序配合工作,而不能使用之前任何版本的Agent。“Enterprise Manager Cloud Control can communicate only with Oracle Management Agent 12c and not with any other earlier release of the Management Agent. You can not configure your exising Agents to communicate with Enterprise Manager 12c OMS.”

 

系统和软件包要求

 

推荐在Oracle Enterprise Linux 5.7或6.1上安装EM 12c的agent , 可以从edelivery.oracle.com 下载到这2款操作系统的安装介质。

以下演示中的主机均采用Oracle Enterprise Linux 5.7 操作系统。

以下表格列出了在Oracle Linux 6或5.x上 安装EM 12c agent ,所要求预装的操作系统软件包,这些软件包可以直接从OS安装DVD介质中找到:

准备工作

 

1. 12c 部署agent 要求在创建必要的credential profile,该credential profile将包含能够从OMS server ssh到目标节点target node的用户身份认证,且要求该用户能够在target node上以sudo执行root用户的权限。

这里我们以oracle用户为例,我们将以目标节点上的oracle用户身份创建credential profile,首先我们要确保oracle用户能够以sudo 执行root用户的权限,这需要用到/etc/sudoers配置文件:

 

!确保/usr/local/bin/sudo 这个符号链接存在
[root@vrh2 ~]# ln -s /usr/bin/sudo /usr/local/bin/sudo
[root@vrh2 m01]# ls -l /etc/sudoers
-r--r----- 1 root root 3407 Oct 18 19:30 /etc/sudoers
[root@vrh2 m01]# cp /etc/sudoers /etc/sudoers.bak 
打开/etc/sudoers 将以下三处修改
修改前:
Defaults   requiretty
修改后:
Defaults:oracle !requiretty
修改前:
Defaults   !visiblepw
修改后:
Defaults   visiblepw
修改前:
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
修改后
##
## Allow root to run any commands anywhere
root    ALL=(ALL)       ALL
oracle  ALL=(ALL)       ALL                        --这里加一行
以上三处修改完成后,save 文件 
测试oracle 能否正常sudo 
[root@vrh2 m01]# su  - oracle
[oracle@vrh2 ~]$ ls -l /root
ls: /root: Permission denied
[oracle@vrh2 ~]$ sudo ls -l /root
[sudo] password for oracle:
total 88
-rw------- 1 root root  1832 Aug 11 05:26 anaconda-ks.cfg
drwxr-xr-x 2 root root  4096 Aug 10 21:31 Desktop
-rw-r--r-- 1 root root 56307 Aug 11 05:26 install.log
-rw-r--r-- 1 root root  4136 Aug 11 05:26 install.log.syslog

 

2. 在目标节点上创建必要的目录 :

 

[root@vrh2 m01]# mkdir /m01
[root@vrh2 m01]# chown oracle:oinstall /m01

 

3.  确保OMS server 和target server 间的通信畅通,如没有使用dns 服务 ,那么不要忘记将host/ip 信息写入到/etc/hosts文件中,如果漏掉这部将报target node can not be  reached 错误

 

正式安装

 

首先再次以sysman身份登录EM https console,如https://192.168.1.169:7799/em。

点击右上角的setup-> Add Target -> Add Targets Manually

 

 

进入Add Targets Manually页面,选择” Add Host Target” ,并点击Add Host …按钮:

 

 

在”add Target – Host and Platform “页面使用默认的”session name”即可,点选”+Add”按钮填入主机名和平台信息:

注意这里推荐填入规范的hostname,如”vrh2.oracle.com”, 注意主机名不能带下划线 “_”, 若Platform下拉列表中没有你要的平台那么说明在该平台上还没有12.1 的agent可用。

 

 

输入完成后点击Next进入”Add Target –  Installation Details ” 页面,点中deployment details 出现下来菜单选择Fresh Agent install ,并填入installation base directory 等目录信息。

 

接着在Named confidential 点击蓝色的”+” 图形按钮,会跳出 create new Named confidential 的窗口,填入之前配好的oracle用户的信息:

 

 

完成后点击Ok,回到原”Add Target –  Installation Details “界面,确认并点击Next:

 

 

进入Review页面,确认信息正确并点击Deploy Agent:

 

 

完成后会进入Agent Deployment summary 页面 ,这里存在三个阶段:

  1. Initialization    — 拷贝agent介质到目标服务器
  2. Remote Prerequisite Check   — 检测目标服务器的安装先决条件
  3. Agent Deployment             –具体的Installation Agent 、Secure Agent 和 执行root.sh

 

若一开始没有正确配置用户的sudo ,则可能在Remote Prerequisite Check阶段出现检测警告,例如下图:

 

 

如果一切顺利,以上三个阶段完成后Agent即在运作了:

 

 

Agent Deployment 的日志存放在 $OMS_HOME/sysman/prov/agentpush/$date目录下,也可以从EM的网页界面上找到这些日志的具体位置。

 

之后点击Target -> host可以看到新加入的主机:

 

 

之后点击Target -> Database  -> add 添加数据库配置信息:

 

在host栏填入新增加的目标服务器,并点击continue:

 

 

EM 会自动找出目标服务器上已有的数据库, 点击Configure 填入dbsnmp用户的密码后保存并Continue:

 

 

之后点击Target -> database 就可以看到新增的数据库了:

 

 

点击数据库名 -> 点击Performance -> Performance Home后可以看到新的12c   的性能总览图:

 

在OEL 5上快速部署Enterprise Manager Cloud Control 12c(12.1)

在OOW 2011期间甲骨文发布了新一代的企业管理器Enterprise Manager Cloud Control 12c,这里我们来介绍如何在Oracle Enterprise Linux 5上快速部署EM 12c和其Agent。

 

硬件要求

准备工作

在正式部署EM 12c 之前我们需要完成一系列的准备工作,包括:

1. 下载EM 12c(12.1) 安装介质

EM 12.1的安装介质可以从Oracle技术网络OTN上找到其下载页面,64位软件的具体下载地址:

 

 

介质包括 disk1和disk2 2个接近3GB的zip压缩包,其中em12_linux64_disk1of2.zip包含了主要的EM binary,而em12_linux64_disk2of2.zip包含了为EM扩展的插件,如支持Exadata、IBM DB2的插件等。

 

2. 在安装EM的Host上创建EM软件的拥有者OS账号

这里我创建oem用户来执行后续的安装操作:

 

groupadd -g 800 oinstall
useradd -g oinstall oem

 

3. 解压安装介质

创建存放解压后安装介质的目录并解压上述zip包:

 

su - oem
[oem@vrh5 tmp]$ mkdir em_cloud
[oem@vrh5 tmp]$ cd em_cloud/
[oem@vrh5 em_cloud]$ unzip ../V28375-01.zip
[oem@vrh5 em_cloud]$ unzip ../V28376-01.zip

 

4. 在EM主机上安装必要的rpm 软件包以及调整/etc/sysctl.conf中的内核参数,该步骤可以通过oracle-validated工具代劳,详见<Understand Oracle Validated Configurations>


5. 为 EM拥有者用户配置必要的ulimit 参数 , 需要修改/etc/security/limits.conf配置文件,如:

[root@vrh5 ~]# tail -10 /etc/security/limits.conf
#ftp             hard    nproc           0
#@student        -       maxlogins       4
# End of file
oem soft nofile 4096
oem hard nofile 4096

 

6. 为EM 12c配置合适的repository database以存放数据

这里可以在Metalink上的Certification Matrix中找到EM 12c已认证的数据库版本,如下图所示 11.2.0.2和11.2.0.3 均已通过该认证:

 

 

这里推荐新建一个11.2.0.2 版本的数据库作为EM Repository。

此外作为EM Repository的数据库还必须使用EM所要求的初始化参数,这些要求包括:

Check the CBO stats gathering job	Disable the stats gathering job
1.Check the processes instance parameter value
The processes instance parameter needs to be set to at least 300.
2.Check the session_cached_cursors instance parameter value.
The session_cached_cursors instance parameter should be set to 300.
Any value between 200 and 500, inclusive, will be accepted.
3.Check the job_queue_processes instance parameter value.
The job_queue_processes instance parameter should be set to 20.
4.Check the shared_pool_size instance parameter value.
The shared_pool_size instance parameter should be set to
at least 600 megabytes or roughly one third of the sga_target size.
5. Check the redo log size.
The size of the EM database instance should be 300 megabytes or greater.
Generally, there should be 3 or more redo logs available of this size.
6. Ensure that the EM tablespace has at least one datafile set to autoextensible
Add at least one datafile with the autoextend attribute to the EM tablespace
7.Check the open_cursors instance parameter value.
The open_cursors instance parameter should be set between 300 and 400, inclusive.
8.Check the sga_target instance parameter value.
The sga_target instance parameter should be set to at least 2 gigabytes, and
roughly twice the size of the pga_aggregate_target setting.
9.Check for invalid objects in the EM repository
Compile all invalid objects in the EM repository

 

可以通过以下命令满足上述的参数要求,当然参数的值还可以适当放大:

 

  alter system set processes= 500 scope=spfile;
alter system set session_cached_cursors=500 scope=spfile;
alter system set shared_pool_size=650M scope=spfile;
alter system set job_queue_processes=22 scope=spfile;
alter database add logfile size 320M;
alter system set open_cursors=350 scope=spfile;
alter system set sga_target=2g scope=spfile;
ALTER SYSTEM SET pga_aggregate_target=1G SCOPE=SPFILE;

 

注意EM 要求 repository database没有配置DB control ,如果有的话需要通过下列命令drop 掉:

 

export ORACLE_HOME= $YOUR_ORACLE_HOME
export ORACLE_SID= $Repository_SID
$ORACLE_HOME/bin/emca -deconfig dbcontrol db -repos drop

 

同时要求sysman 和 sysman_mds、 sysman_opss用户不存在,已创建该用户的DB 可以drop 掉:

 

SQL> select * from v$version;
BANNER

7. 确保能够从EM 主机顺利登录到 repository 数据库 :

 

[oem@vrh5 tmp]$ tnsping vrh4:1521/SBDB
TNS Ping Utility for Linux: Version 11.2.0.2.0 - Production on 16-OCT-2011 21:18:24

SQL>

 

8. 确保网络正常

这里要求EM主机必须使用statics IP 静态IP ,否则安装会出错, 且已正确在/etc/hosts或DNS配置唯一的域名解析

 

正式安装

 

我们开始正式通过OUI安装Oracle Enterprise Manager Cloud Control 12c(12.1),这里要用到图形化的界面,确保DISPLAY环境变量正确或者使用Xmanager之类的软件:

 

(oem)$ unset ORACLE_HOME ORACLE_BASE ORACLE_SID
(oem)$ export DISPLAY=:0
(oem)$ cd /tmp/em_cloud/
注意这里若你的EM Host拥有多个host name ,那么要使用ORACLE_HOSTNAME参数指定规范的host name 
如/etc/hosts 中的信息为: 192.168.1.8 vrh5 vrh5.oracle.com 
那么要选用vrh5.oracle.com 这个hostname 
如果host name 中带"_"符号 可能导致安装失败
(oem)$ ./runInstaller ORACLE_HOSTNAME=vrh5.oracle.com
Starting Oracle Universal Installer…

 

如下图OUI界面顺利启动,勾销” I wish to receive security update…”,并点击Next:

 

 

 

Prerequisite Checks会检测EM安装的前提条件,这里因为物理内存不足(要求3g)而出现Warning,点击Next忽略该警告

 

 

点击Yes,忽略该问题

 

 

若检测顺利,则如下图:

 

 

下一步选择create a new Enterprise Manager -> Simple ,为Middleware Home location选定一可用的空目录,注意目录的拥有者应为oem(EM 所有者用户)

 

 

选择想要安装的插件,这里我们不安装额外的插件,保持默认配置点击Next:

 

 

选择暂时不安装Exalogic Elastic Cloud Infrastructure插件, Install Later:

 

 

配置Weblogic Server,填入Weblogic和Node Manager密码及OMS instance Base Location:

 

 

配置数据库连接信息,填入repository database的连接信息:

 

 

输入 sysman用户和Agent注册使用的密码, 安装程序会自动为你提供EM所需创建表空间数据文件的位置:

 

 

选择EM 12c将要使用的端口,一般默认即可,除非这些端口有其他用途:

 

 

点击 Next后 再点击Install Now进入安装过程:

 

 

安装流程包括Copy Files、Configure Plugins Prerequisites Check、Repository Configuration、MDS Schema Configuration、OMS Configuration、Plugins Deployment and Configuration 、 Start Oracle Management Service、 Oracle Configuration Manager Repeater、Agent Configuration Assistant 、Run root scripts,总耗时在1个小时左右。

在此过程中推荐监控安装进程的日志,这些日志的位置如下:

例如:
/m01/midd/oms/sysman/log/schemamanager/m_$date/m_$date.CREATE/em_repos_config.log
/m01/midd/oms/sysman/log/schemamanager/m_$date/m_$date.CREATE/emschema.log
/m01/midd/oms/cfgtoollogs/cfgfw/oracle.sysman.top.oms_*.log
/m01/midd/oms/cfgtoollogs/omsca/*.log

em_repos_config.log记录了em repository的配置日志,在此安装过程中可能遇到如下错误:

SEVERE: oracle.sysman.top.oms:MDS Schema Creation is failed 创建失败是由bug引起的

 

遇到该错误后,手动登录到数据库并执行以下create user命令:

 

 create user SYSMAN_MDS identified by sysman_mds;

创建该SYSMAN_MDS用户后,回到安装界面并点击retry按钮,安装会继续下去。

OMS和Agent配置过程中的日志如下:
