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

2011/10/19 by 6 Comments

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

2011/10/18 by 4 Comments

在<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:

更多关于OS软件要求的信息，可以直接访问EM 安装手册 <Meeting Package, Kernel Parameter, and Library Requirements>章节。

 

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:

更多关于OS软件要求的信息，可以直接访问EM 安装手册 <Meeting Package, Kernel Parameter, and Library Requirements>章节。

 

 

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

drop user mgmt_view cascade;

@?/rdbms/admin/catsnmp

 

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:

INFO: oracle.sysman.top.oms:__________________________DUMPING PARAMETERS

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:

Oracle Database 12c(12.1) Beta已经开始内部测试

2011/10/15 by 3 Comments

据悉Oracle Database 12.1 (12c)这个未来版本的Beta版已经开始在Oracle内部大规模测试，见下图:

 

 

12c的官方文档已经在Oracle内部网络可访问，包括Concepts、Reference和SQL Tuning Guide等，但似乎还没有12c 12.1 New Feature的文档。

以下为12.1 12c使用DBUA图形化工具升级数据库的界面，可以看到图形化界面的美学风格和11gR2没有太大的差别。

 

 

这些文档在外部尚不能访问，但是12c Release 1 (12.1) Beta的文档主页已经建立:

Oracle 12c coming soon?

2011/04/13 by 6 Comments

Oracle的扛鼎产品Database Software数据库软件12c版本何时会发布？

就这一问题，我们来回顾一下Oracle数据库产品发布的历史年表:

Release Release Date Elapsed Years
Oracle 6 1988
Oracle 7 1992 4
Oracle 8 1997 5
Oracle 8i 1998 1
Oracle 9i 2001 3
Oracle 10g 2004 3
Oracle 11g 2007 3
Oracle 12c Unknown till now 4

 

到11g为止(Oracle 11g的Beta版本最早在2006年招募内部测试者)，Oracle平均每3.6年发布新的一代数据库产品。

根据以往的经验以及一些小道消息(部分来自于Oracle Staff)，我们有理由相信在今年(2011)的第三或第四季度Oracle可能会展开对Database 12c的Beta测试，并且会在2012年的第一季度为其下一代的重量级数据库产品Oracle Database 12c揭开序幕！

在2012同期可能发布的重量级产品还有Microsoft微软公司的旗舰产品Windows 8。

如果不出意料的话我们有幸在2012-Dec-21之前体验到以上这2款软件，俗套地说:”神马都是浮云啊！“
