Oracle DB - 11g 使用 DBNEWID utility (nid) 指定 new DBNAME db_id

舊 db_name: PRD
新 db_name: QAS

STEP 1: Backup the database.

STEP 2: Mount the database after a clean shutdown:

SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> STARTUP MOUNT

Perl script 錯誤訊息 Can't locate Mail/Sendmail.pm 解決辦法

在新的Linux Server（Oracle Enterprise Linux Server 6.8)）上配置tablespace空間告警的perl script後，測試時報錯如下

[oracle@testdb88 ~]$ ~/perl/mailTableSpaceSize.pl bypass
Can't locate Mail/Sendmail.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /home/oracle/perl/mailTableSpaceSize.pl line 6.
BEGIN failed--compilation aborted at /home/oracle/perl/mailTableSpaceSize.pl line 6.

Perl腳本mailTableSpaceSize.pl如下所示，其中使用了Mail::Sendmail郵件模塊。
#!/usr/bin/perl

use DBI;
use Mail::Sendmail;
use MIME::QuotedPrint;
use MIME::Base64;
use Encode;
use Number::Format qw(:subs);
use DateTime qw();

出現這個錯誤是因為Perl沒有安裝Mail::Sendmail模組，安裝此模組問題即可解決，可以使用下面幾種方式安裝。 (使用cpan安裝，Server要能夠連上網路，否則無法下載相關package。

[Best]

CPAN shell

perl -MCPAN -e shell
install Mail::Sendmail

cpanm

cpanm Mail::Sendmail

[Traditional]

perl Makefile.PL
make
make test
make install

[Manual]

Copy Sendmail.pm to Mail/ in your Perl lib directory.

常見的誤解 - 人不為己天誅地滅

節錄自 https://linriva.pixnet.net/blog/post/62534027-%E5%8D%97%E6%87%B7%E7%91%BE%EF%BC%9A%E3%80%8C%E4%BA%BA%E4%B8%8D%E7%82%BA%E5%B7%B1%EF%BC%8C%E5%A4%A9%E8%AA%85%E5%9C%B0%E6%BB%85%E3%80%8D%E5%8E%9F%E4%BE%86%E6%98%AF%E9%80%99%E5%80%8B

我一直以為，這句話的意思是：人如果不為自己謀利、謀權、謀色，就要招到天地誅殺。其實，這是誤解。

　　現在才知道，「人不為己天誅地滅」，出處是《佛說十善業道經》第二十四集：：人生為己，天經地義，人不為己，天誅地滅。佛家的意思是：不殺生、不偷盜、不邪淫、不妄語、不兩舌、不绮語、不惡口、不貪欲、不嗔恚、不邪見，才是「為自己」。不為自己製造新的惡果，不為自己造成新的災禍，這才是「為自己」。只有這樣才不會天誅地滅。

SAP - Profile Administration (transaction RZ10) 參數設定

SAP建議使用事務T-CODE RZ10調整SAP配置文件。但是，例如，如果由於錯誤的配置而無法再啟動SAP系統，則可以在文件系統級別上更改相應文件中的SAP參數。

下方例子
1. 修改參數 login/min_password_lng
2. 新增參數 login/min_password_digits

When using the helper file, remember to reload the profiles with transaction RZ10 afterwards! Utilities → Import profiles → Of active servers
a) First look up the current values of the profile parameters you want to change. Go to transaction RZ11 and enter the Param. Name, for example login/min_password_lng. Choose Display. Note the Current value. Repeat this for the other parameters you want to change.
b) To change the parameters in the SAP system, go to transaction RZ10. By using the F4 help select DEFAULT as Profile, select Extended Maintenance and choose Change.
c) To change an already existing parameter, for example login/min_password_lng, simply click into this row and choose Change
d) Enter the new value in the Parameter val. field, for example 8. Choose Copy and Back.
e) To add a new parameter choose Create. Enter the Parameter name, for example login/min_password_digits. Enter the Parameter val., for example 1. Choose Copy twice and Back.
f) In the parameter list choose Copy and Back.
g) Choose Save and in the popup choose No. In the Activate profile popup choose Yes. Then Continue twice.
h) Now restart your SAP system. First stop the Dialog Instance and afterwards the Central Instance. Start in the opposite order. Log on to operating system level of your SAP system and double click the desktop shortcut SAP Management Console. In the new window right click on one instance of your system and choose Stop. After it is stopped, right click and choose Start.
i) After the system is started again, log on and change your password in transaction SU3. If you set parameter login/password_compliance_to_current_ policy to 1 you may need to change your password directly after logging on. Try to violate any parameter you set. You successfully changed some password parameters of your AS ABAP based SAP system.

login/min_password_diff = 3
--Defines the minimum number of characters that must be different in the new password compared to the old password.

login/password_expiration_time = 90
#login/password_expiration_time 密碼有效期
#Default: 0

#Permissible values: 0 - 1000

login/min_password_lng = 6
--Default: 6
--Permissible values: 3 - 40
--Defines the minimum length of the password.

login/failed_user_auto_unlock = 0
--Defines whether user locks due to unsuccessful logon attempts are automatically removed at midnight.

login/no_automatic_user_sapstar = 0
--login/no_automatic_user_sapstar 用戶SAP* 能不能登錄, 0代表SAP*可以登錄，1代表SAP*不能登陸！

login/fails_to_user_lock = 6
--login/fails_to_user_lock 密碼輸錯多少次後鎖定

login/min_password_letters = 2
--Defines the minimum number of letters (A-Z) in passwords.

login/min_password_digits = 2
--Defines the minimum number of digits (0-9) in passwords.

login/system_client = 800
--login/system_client 登錄時默認的Client號

Oracle DB - Creating Linux Services for DB auto-start auto-stop Oracle 19c On OEL7

創建 Linux Services - dbora
Create a new service to automatically start/stop an Oracle database. This assumes the Oracle database is not using Oracle Restart and the "start_all.sh" and "stop_all.sh" scripts are already present.

# vi /lib/systemd/system/dbora.service

[Unit]
Description=The Oracle Database Service
After=syslog.target network.target

[Service]
# systemd ignores PAM limits, so set any necessary limits in the service.
# Not really a bug, but a feature.
# https://bugzilla.redhat.com/show_bug.cgi?id=754285
LimitMEMLOCK=infinity
LimitNOFILE=65535

#Type=simple
# idle: similar to simple, the actual execution of the service binary is delayed
# until all jobs are finished, which avoids mixing the status output with shell output of services.
RemainAfterExit=yes
User=oracle
Group=oinstall
Restart=no
ExecStart=/bin/bash -c '/home/oracle/scripts/start_all.sh'
ExecStop=/bin/bash -c '/home/oracle/scripts/stop_all.sh'

[Install]
WantedBy=multi-user.target

Reload systemd so it can see the new service.
# systemctl daemon-reload

Start the service and enable so it is automatically restarted on reboot.
# systemctl start dbora.service
# systemctl enable dbora.service
# systemctl status dbora.service

Complete!

如果用 RHEL7 or CentOS7, 可以安裝 OL7 repository. It will pull the dependencies from your normal repositories.
# yum install -y https://yum.oracle.com/repo/OracleLinux/OL7/latest/x86_64/getPackage/oracle-database-preinstall-19c-1.0-1.el7.x86_64.rpm

Additional Setup

Set the password for the "oracle" user.
passwd oracle

Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=permissive

Once the change is complete, restart the server or run the following command.
# setenforce Permissive

If you have the Linux firewall enabled, you will need to disable or configure it, as shown here or here. To disable it, do the following.
# systemctl stop firewalld
# systemctl disable firewalld

Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/19.0.0/dbhome_1
mkdir -p /u02/oradata
chown -R oracle:oinstall /u01 /u02
chmod -R 775 /u01 /u02

Create a "scripts" directory.
mkdir /home/oracle/scripts

Create an environment file called "setEnv.sh". The "$" characters are escaped using "\". If you are not creating the file with the cat command, you will need to remove the escape characters.
cat > /home/oracle/scripts/setEnv.sh <<EOF

Add a reference to the "setEnv.sh" file at the end of the "/home/oracle/.bash_profile" file.
echo ". /home/oracle/scripts/setEnv.sh" >> /home/oracle/.bash_profile

Create a "start_all.sh" and "stop_all.sh" script that can be called from a startup/shutdown service. Make sure the ownership and permissions are correct.
