Oracle 接管微软角色 正压制开源精神（oracle microsoft）
微软在进入企业操作系统领域的时候被认为是大恶魔。现在看起来 Oracle 替代了微软的角色。Adobe 的官员 Dave McAllister 最近就在他公司的博客上这些写道 “…... 突然之间，Oracle 接管了微软曾经扮演的角色。而且我以前甚至不知道他们当过预备演 员。”
Oracle 其中一个让人抱怨的决定就是抽离了 OpenSolaris 项目，限制 OpenSolaris 项目必须在商业版 Solaris 发布 之后才能发布。这个决定是在公司发给 Solaris 的工程师邮件中声明的。随后发布在 OpenSolaris 工程师 Stallion 的博客中，“按这种方 式，就可以保证新技术就会先体现在我们的商业版本中而不是其他地方，”Oracle 邮件这么说。“我们不会再实时给 Solaris 操作系统贡献任何代码， 因为它已经开发完成了。” 还加了这么一句。
Stallion 对于 Oracle 扼杀 OpenSolaris 操作系统的决定非常失望，并且他这么认为：他为开源社区的项目花费了大量是时间编写代码，但是却被这个贪婪的新恶魔全部毁掉了。
这是对花费无数时间的工作痛苦的送别 — 因为这个优质的软件现在正式成为了 Oracle 的产品，我们再也不能不受限制的获得她。我只是为了能让我们的软件能更优秀而不停的维护她，而不是为了任何一个公司的盈亏。这种行为彻底违反了开源精神。
Stallion 当然不是唯一一个持有这个观点的人，但是让人悲伤的是所有的一切都太容易预测了：就像微软一样，Oracle 也是一个拥有数 十亿美元资产的公司，它的本性就是不停的赚钱。Oracle 对于 “开源精神” 唯一的兴趣点就是她能帮助公司获取更大的利润。其他时候就是为了市场的目的而 敷衍。微软和 Oracle 每次在看到开源操作系统的财务报告肯定要窃笑，就知道你们不会因为专心于做软件而变得富裕。
Oracle 已经非常清楚自己的可与有 60% 没有使用 Solaris 操作系统，因此它可以承诺优化 Oracle 数据库在 Solaris 的性 能，让 Oracle 在 Solaris 的性能比其他系统上运行的更好，那么就可以让一部分用户转移到 UNIX 操作系统，Oracle 就有机会变得更富有了。
Oracle 可能已经从 OpenSolaris 项目和像 Stallion 这样的开源社区开发者那里得到了好处，但是它看起来已经觉得将来不会 再得到多大的好处。或者它只是简单的认为如果没有 OpenSolaris 在背后污染环境那么已经习惯专利软件的 Oracle 数据库用户更可能购买 Solaris 操作系统。不管出于什么原因，Oracle 相信如果没有 OpenSolaris 它会赚更多的钱，因此 OpenSolaris 必须死；开源精 神真该死。
开发周期短？用户不感兴趣？对待社区贡献者苛刻？大多数可能是这样。吃惊吗？一点都不，开源精神可能会创造伟大的软件，但是成为软件界的大恶魔会带来大量的财富。然而后者才是想 Oracle，微软这样的公司真正关心的。

How I Simplified Oracle Database 12c and 11g Installations on Oracle Linux 6
How I Simplified Oracle Database 12c and 11g Installations on Oracle Linux 6
by Ginny Henningsen; updated by Michele Casey
How to simplify the installation of Oracle Database 12c or 11g on Oracle Linux 6 by installing the oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall RPM package, which automatically performs a number of tasks, such as installing required software packages, resolving package dependencies, and modifying kernel parameters.
Published September 2012 (updated September 2017)
READ THIS FIRST: Important Changes Since Publication
While the content in this article is still valid, several details have changed. For example:
- For Oracle Database 12c Release 2, the preinstall RPM has a different name than the one used in the article belowpu:
- oracle-database-server-12cR2-preinstall
- See also this documentation: Automatically Configuring Oracle Linux with Oracle Preinstallation RPM
- The preinstall RPMs are published on Oracle Linux yum server for both Oracle Linux 6 and 7 in the Latest repositories which are configured and enabled by default in recent releases of Oracle Linux 6 and 7
Introducing the oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPM for Oracle Linux
Before installing Oracle Database 12c or 11g on a system, you need to preconfigure the operating environment since the database requires certain software packages, package versions, and tweaks to kernel parameters. (Be sure to review the appropriate Oracle Database installation guide to familiarize yourself with hardware, software, and operating system requirements.)
|
Note: This article applies to Oracle Linux 6. A previous article, "How I Simplified Oracle Database Installation on Oracle Linux," covered performing a similar task on versions of Oracle Linux 5.
On Oracle Linux, I discovered that there is a remarkably easy way to address these installation prerequisites: First, depending on your database version, install either the RPM package called oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall. This RPM performs a number of preconfiguration steps, including the following:
- Automatically downloading and installing any additional software packages and specific package versions needed for installing Oracle Grid Infrastructure and Oracle Database 12 c Release 1 (12.1) or 11g Release 2 (11.2.0.3), with package dependencies resolved via
yumorup2datecapabilities. - Creating the user
oracleand the groupsoinstall(forOraInventory) anddba(forOSDBA), which are used during database installation. (For security purposes, this user has no password by default and cannot log in remotely. To enable remote login, please set a password using thepasswdtool.) - Modifying kernel parameters in
/etc/sysctl.confto change settings for shared memory, semaphores, the maximum number of file descriptors, and so on. - Setting hard and soft shell resource limits in
/etc/security/limits.conf, such as the locked-in memory address space, the number of open files, the number of processes, and core file size. - Setting
numa=offin the kernel for x86_64 machines.
Note that oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall parses the existing /etc/sysctl.conf and /etc/security/limits.conf files and updates values only as needed for database installation. Any precustomized settings not related to database installation are left as is.
The oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPM packages are accessible through the Oracle Unbreakable Linux Network (ULN, which requires a support contract), from the Oracle Linux distribution media, or from the Oracle public yum repository. Thus, whether or not your system is registered with ULN to access Oracle patches and support, you can use oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall to simplify database installation on Oracle Linux. In addition, the Oracle public yum repository now includes all security and bug errata, ensuring systems are secured and stable with the latest security updates and bug fixes.
Installing the oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall RPM
The remainder of this article steps through the procedure that I used for installing oracle-rdbms-server-11gR2-preinstall on Oracle Linux via the Oracle public yum repository. The same steps outlined in the following section can be used for either version of the preinstall RPM package. I started with a system running Oracle Linux Release 6 Update 4 for x86_64, a 64-bit version of Oracle Linux that I downloaded from the Oracle software delivery cloud (requires registration or login). First, I set up a yum configuration file that pointed to the correct repository, and then I installed the oracle-rdbms-server-11gR2-preinstall RPM from that repository.
Here are the steps for preconfiguring a system for Oracle Database installation using oracle-rdbms-server-11gR2-preinstall. Remember, the steps are the same when using the oracle-rdbms-server-12cR1-preinstall package; you simply need to change the name of the RPM package during the yum installation step.
- As an authorized user (for example,
root), retrieve the file that configures repository locations:
# cd /etc/yum.repos.d # wget http://yum.oracle.com/public-yum-ol6.repo
- Using a text editor, modify the file, changing the field
enabled=0toenabled=1to reflect repositories that correspond to the machine''s operating system release.
Here is an excerpt of
public-yum-old6.repowith the changed lines in boldface.[ol6_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/ gpgkey=http://yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 [ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=http://yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1
Because the target system is running Oracle Linux Release 6 Update 4 for x86_64, which installs the Oracle Unbreakable Enterprise Kernel by default, there are two repositories to enable,
[ol6_latest]and[ol6_UEK_latest]. - Next, install the
oracle-rdbms-server-11gR2-preinstallRPM using theyum installcommand. If you are using Oracle Database 12c, then you would typeyum install.
The output in Listing 1 shows how the installation checks dependencies and then downloads and installs the required packages.

oracle-rdbms-server-11gR2-preinstallRPMThe yum installation logs messages about kernel changes in the file
/var/log/oracle-rdbms-server-11gR2-preinstall/results/orakernel.log, and it makes backups of current system settings in the directory/var/log/oracle-rdbms-server-11gR2-preinstall/backup. - At this point, the system is ready for the installation of Oracle Database. For example, to install Oracle Database 11g Release 2, follow the directions in Chapter 4, "Installing Oracle Database," of the Database Installation Guide for Linux."
Here are the steps I followed while installing Oracle Database 11g Release 2 in my test environment. Make sure you review all documentation and follow recommended best practices before installing into your production environment.
- As
root, create a parent directory in a file system that has sufficient space to be the target location for the downloaded files:
# mkdir /home/OraDB11g # cd /home/OraDB11g
The amount of disk space needed in the file system varies according to the specific installation type, but roughly twice the size of the zip archives, or 5 GB, is enough to house the software and data files.
- Into this target directory, download the installation media files from the Oracle Database Software Downloads page on Oracle Technology Network.
- Extract the files:
# unzip linux.x64_11gR2_database_1of2.zip # unzip linux.x64_11gR2_database_2of2.zip
- Log in as the user
oracle. Change directory to thedatabasedirectory and enter the following command to run the Oracle Universal Installer:
$ cd /home/OraDB11g/database $ ./runInstaller
The Oracle Universal Installer performs a number of checks, verifying that the necessary OS packages and versions are installed. In addition, it checks kernel parameters set by the
oracle-rdbms-server-11gR2-preinstallinstallation. During the kernel settings check, the installer might flag a few settings as "failed," and you should investigate these failures. In some cases, you still might be able to continue with the database installation. If you check kernel settings in/etc/sysctl.conf, you''ll see thatoracle-rdbms-server-11gR2-preinstallhas modified and added the necessary settings to ensure the minimum requirements are met, as defined in section 2.10.1, "Displaying and Changing Kernel Parameter Values," in Chapter 2, "Oracle Database Preinstallation Requirements," of the Oracle Database Installation Guide 11g Release2 (11.2) for Linux. Below is the list of requirements:fs.aio-max-nr = 1048576 fs.file-max = 6815744 kernel.shmall = 2097152 kernel.shmmax = 4294967295 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576
If necessary, you can (as
root) edit the file/etc/sysctl.confto specify a setting manually, for example:# vi /etc/sysctl.conf # /sbin/sysctl -p
The Oracle Universal Installer performs additional checks, such as verifying the
glibcversion, sufficient disk space, environmental variable and path settings, and sufficient physical memory and swap space. Generally, installingoracle-rdbms-server-11gR2-preinstalltakes care of the prerequisites so that you can proceed directly with installing the database. - As
Final Thoughts
Installing the oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPMs can save time when installing Oracle Database 12c and 11g on Oracle Linux. These RPMs address most Oracle Database installation prerequisites and greatly simplify the installation process.

NodeJS-Oracle DB - NJS-040 连接超时，在 ICP 中使用带有 Lopback 的 oracle 驱动程序（loopback-connector-oracle）
如何解决NodeJS-Oracle DB - NJS-040 连接超时，在 ICP 中使用带有 Lopback 的 oracle 驱动程序（loopback-connector-oracle）？
我正在使用 loopback-connector-oracle 4.1.1 版寻求有关我面临的问题的一些信息。分析如下： 我们有 DB 连接配置，可以使用 json 文件格式的 oracle 连接器使用属性连接到 oracle DB 数据源。 "maxConn": 20,“主机”：DB_HOST， “端口”：DB_PORT， “数据库”：DB_NAME， “密码”：DB_PASSWORD， “用户”：DB_USER， "connector": "oracle",
有两个进程/pod 正在运行，每个进程/pod 都有自己的池供oracle 连接器使用。发生的情况是，在一个实例中，oracle 能够连接并处理请求，但在第二个 pod/进程中，我注意到 njs-040 错误连接超时。由于两者都运行在同一个环境中，所以连接性不会成为问题。我正在寻求您的帮助或意见以了解连接池耗尽的原因？正如我所看到的，DB 上的连接/会话数量配置的数量较少。 当我重新启动 pod/进程时，一切都会恢复正常。在我的流程中遇到的一些问题，如果您可以指导并提供宝贵的意见，我正在寻求您的帮助。
- 如果使用连接池（oracle 连接器），它也应该释放对象，耗尽的机会会减少吗？
- 在进程/pod 启动并通过连接器 (oracle) 获取数据源中的连接对象后，发生网络问题并且进程和数据库之间的连接丢失，连接器是否恢复？根据我的观察，我在其他进程中注意到的似乎应该被恢复，当它与范围一起运行时，在一个进程中可能会导致什么？
我非常感谢您的回复。 提前致谢 桑吉夫

Oracle 10g AND Oracle 11g手工建库案例--Oracle 11g
Oracle 10g AND Oracle 11g手工建库案例--Oracle 11g
系统环境：
操作系统： RedHat EL6
Oracle： Oracle 10g and Oracle 11g
手工建库相对来说很容易实现，本案例是从10g和11g，通过手工建库的方式做一个简单的对比，可以看出11g和10g之间的一个简单的差异！
VMware+Linux+Oracle 10G RAC全程详细图解
案例二：
在Oracle 11g 环境下手工建库
DB_NAME=''test1''
INSTANCE_NAME=''test1''
1、建立Instance的初始化参数文件和口令文件
[oracle@rh6 dbs]$cat inittest1.ora
db_name=''test1''
memory_target=400m //Oracle 11g增加了内存自动管理
processes = 150
audit_file_dest=''$ORACLE_BASE/admin/test1/adump''
audit_trail =''db''
db_block_size=8192
db_domain=''''
open_cursors=300
remote_login_passwordfile=''EXCLUSIVE''
undo_tablespace=''UNDOTBS1''
# You may want to ensure that control files are created on separate physical
# devices
control_files = /u01/app/oracle/oradata/test1/control01.ctl
compatible =''11.2.0''
[oracle@rh6 dbs]$ orapwd file=orapwtest1 password=oracle entries=3
2、建立数据库相关的目录
Oracle 11g增加了diagnostic directory，，默认的为$ORACLE_BASE
[oracle@rh6 dbs]$ mkdir -p $ORACLE_BASE/admin/test1/adump
[oracle@rh6 dbs]$ mkdir -p /u01/app/oracle/oradata/test1
3、建立建库脚本
[oracle@rh6 ~]$ cat cr_db.sql
CREATE DATABASE test1
USER SYS IDENTIFIED BY oracle
USER SYSTEM IDENTIFIED BY oracle
LOGFILE
GROUP 1 (''/u01/app/oracle/oradata/test1/redo01a.log'') SIZE 50M ,
GROUP 2 (''/u01/app/oracle/oradata/test1/redo02a.log'') SIZE 50M
MAXLOGFILES 10
MAXLOGMEMBERS 5
MAXLOGHISTORY 1
MAXDATAFILES 200
CHARACTER SET zhs16gbk
DATAFILE ''/u01/app/oracle/oradata/test1/system01.dbf'' SIZE 325M REUSE
SYSAUX DATAFILE ''/u01/app/oracle/oradata/test1/sysaux01.dbf'' SIZE 325M REUSE
DEFAULT TEMPORARY TABLESPACE tempts1
TEMPFILE ''/u01/app/oracle/oradata/test1/temp01.dbf''
SIZE 100M REUSE
UNDO TABLESPACE undotbs1
DATAFILE ''/u01/app/oracle/oradata/test1/undotbs01.dbf''
SIZE 200M REUSE AUTOEXTEND ON MAXSIZE UNLIMITED;
4、启动Instance并建立数据库
[oracle@rh6 ~]$ export ORACLE_SID=test1
[oracle@rh6 ~]$ sqlplus ''/as sysdba''
