Create keystores for Weblogic 12C

To create keys issue the following commands:

keytool -genkey -keyalg RSA -alias aliasdemo -keystore alias_identity.jks -dname "CN=CEN-BI-DS-ODI01, OU=alias_demo, O=alias_demo, L=Mexico, ST=Mexico, C=MX" -storepass passW0rd -validity 3600 -keysize 2048 -keypass passW0rd
keytool -selfcert -v -alias alias_demo -keypass passW0rd -keystore alias_demo_identity.jks -storepass passW0rd -storetype jks -validity 3600
keytool -export -v -alias alias_demo -file "alias_demo.gob.mx-rootCA.der" -keystore alias_demo_identity.jks -storepass passW0rd
keytool -import -v -trustcacerts -alias alias_demo -file "alias_demo.gob.mx-rootCA.der" -keystore alias_demo_trust.jks -storepass passW0rd

Steps to deploy them in weblogic server

• Identity Keystore: "/opt/oracle/keystore/alias_identity.jks"
• Trust Keystore: "/opt/oracle/keystore/alias_trust.jks"
• Alias: cenace
• Store Password: passW0rd
• Key Password: passW0rd
• Valid for: 3600 Days (Approx 10 Years)

ODI 12c Loop PLSQL Procedure

Here's the procedure I commonly use to implement a odi loop in package.!

create or replace function sys.set_initial_data (P_TOKEN varchar2, P_VALUE varchar2, P_ROW_ID number, p_session number) return varchar2
is
PRAGMA AUTONOMOUS_TRANSACTION;

res varchar2(50);

cursor get_datap is
select *  from process_data_odi
where 1=1--status = (select case P_VALUE when 'ROW' THEN  'R' else 'P' end from  dual)
and status = 'P';
--and id_host = nvl(null,id_host);

vget_datap get_datap%rowtype;

cursor get_datap_id is
select *  from process_data_odi
where 1=1--status = (select case P_VALUE when 'ROW' THEN  'R' else 'P' end from  dual)

Configure CDC ODI 12C with Reusable Mappings

1.- Identify the source and target locations
2.- Create your source model, and target model
3- In my case I created the CDC_Test model connected to a Database 11g XE Edition and my target is a Database 12c EE

Goldengate is a oracle product to syncronize legacy systems or databases using the log files, but is quite expensive, in this case we are going to see, how to do a sync between two systems using just ODI 12C,

Using CDC Simple  Mode:

1.- Create a Project and import JKM Oracle Simple

2.- Change de Model of CDC_Test to Simple

3.- Do the Reverse-Engineering for the tables to add to CDC, in this case the table I chose was SRC_CITY.

4.- Once you have the datastore in your data model, Now configure the CDC, right clic over the datastore SRC_CITY and Add to CDC.

5.- Add a subscriber, right clic over datastore and navigate to subscriber, Add subscriber

6.- Add the subscriber SUNOPSIS

7.- Start Journal, select the subscriber, then session is prompted to start, clic ok.
Note:
The steps to undo this are (Unsubscribe, Drop  Journal, Remove from  CDC)

8.- So far, we have configured the basic CDC Simple, let's remember this is intrusive, because it creates triggers over the source tables and may affect the performance, so check carefully.

9- Test

10.- Now let's do this automatically using a package, mapping (ODI Interface in ODI 11G) and reusable mapping

11.- Create a Reusable Mapping, just drag the source table (The one you just added to CDC, see above), and also drag an output signature and do the mapping.

12.- Create a mapping in ODI and drag the reusable mapping created in the last step.

13.- Drag the target table and do the mapping.

14.- Choose the Optimization context to Development
15.- Configure the Journalize Data (select CheckBox)
16.- In the Logical Section change the target to  Incremental Update
17.- In the Physical, select the target TRG_CITY, and in the section Integrated Knowledge Module change to IKM Oracle Incremental Update

Look like this:

18.- Create a package to automatize this.
19.- Drag a OdiWaitForLogData component

OdiWaitForLogData "-CONTEXT=DEVELOPMENT" "-GLOBAL_ROWCOUNT=1" "-LSCHEMA=GG_SOURCE" "-OPTIMIZED_WAIT=AUTO" "-POLLINT=1000" "-SUBSCRIBER_NAME=SUNOPSIS" "-TIMEOUT=0" "-TIMEOUT_WITH_ROWS_OK=YES" "-TABLE_NAME=SRC_CITY"

20.- Drag the interface into the package and make a connection to the OdiWaitForLogData and viceversa

21.- Test the package.

SELECT * FROM SALES_DATA.SRC_city;

SELECT count(*) FROM SALES_DATA.SRC_city;

SELECT * FROM SALES_DATA.SRC_city;

delete from SALES_DATA.SRC_city where city_id = 100;

commit;

insert into SALES_DATA.SRC_city values (100,'Acapulco',20,123456);

commit;

Install and configure Admin Tool with OBIEE 12C - IAAS Cloud

First of all you need to install the client required, the file:

Setup_BI_Client_12.2.1.0.0_Windows.X64

you can download it en the oracle web page, or e-delivery.

http://download.oracle.com/otn/nt/bi/1221/Setup_BI_Client_12.2.1.0.0_Windows.X64.zip

once you have installed, we proceed to configure it in order to allow connection,

we need first, configure tnsnames.ora.

1.- Navigate to C:\Oracle\Middleware\Oracle_Home\network\admin
(if the folder doesn't exist create it)

2.- Create file tnsnames.ora pointing out to the database you want to connect.

example:

# tnsnames.ora Network Configuration File mntopc_dataproduct12.1.0db_1networkadmintnsnames.ora
# Generated by Oracle configuration tools.

CLOUDCDB1 =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db_private)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = cloudcdb1)
    )
  )

CLOUDCDB1_PDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = db_private)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = pdborcl)
    )
  )

3.- Configure DNS System Entries

The port 9514

4.- Select the tables as you desire and build your model

Linux IAAS, Usefull commands

One you have attached a volume here you have usefull commands:

Disk information:

lsblk
blkid

Mount: sudo mount /dev/xvdc /mnt/opc_data

Format : sudo mkfs -t ext3 /dev/xvdc

Install if needed:
sudo yum install e4fsprogs

Create folder if needed:
sudo mkdir /mnt/opc_data

mount as default:
vi /etc/fstab

add following line:
/dev/xvdc               /mnt/opc_data        ext3    defaults        0 0

Change user and group one command:
sudo chown opc:opc opc_data/

Check if process is on startup:
chkconfig --list | grep vncserver
"vncserver       0:off   1:off   2:on    3:on    4:on    5:on    6:off"

install vncserver if not installed:
yum install tigervnc-server

Put vncserver on startup:
sudo chkconfig vncserver on

Configure vncserver once installed (modify according your settings)
cat  /etc/sysconfig/vncservers

VNCSERVERS="2:opc 3:oracle"
VNCSERVERARGS[2]="-geometry 1280x1024 -nolisten tcp -localhost"
VNCSERVERARGS[3]="-geometry 1280x1024"

Restart Service

sudo service vncserver start
sudo service vncserver stop

sudo service vncserver status

Use vncpasswd to change password users

vncpasswd opc

If you don't have xterm install it
sudo yum install xterm

Enable X11Forwarding

sudo vi /etc/ssh/sshd_config

Restart sshd

sudo /etc/init.d/sshd restart

With operative systems with no graphic interface, but you want enable vncserver:

gconftool-2 -s -t bool /apps/gnome-screensaver/lock_enabled false

vncserver :3 -depth 16 -alwaysshared -geometry 1200x1024 -s off

sudo yum install xorg-x11-twm

sudo yum install xterm

sudo yum install xsetroot

sudo yum install xorg-x11-apps

Add LC_ALL=en_US; export LC_ALL=en_US in .bashrc or in .bash_profile 

sudo yum install liberation-sans-fonts

same procedure as vncserver

search text in files recursively in a folders and subfolders:
grep -rl 'windows' ./ | xargs sed -i 's/windows/linux/g'

grep -rnw . -e 172.28.88.111 --exclude-dir={*.out,*.log}
grep -rnw . -e 172.28.88.111 --exclude={*.out*,*.log*}

using escape character: 
grep -rl '/opt/oracle/obiee/user_projects' ./ | xargs sed -i 's/\/opt\/oracle\/obiee\/user_projects/\/opt\/oracle\/admin\/user_projects/g'

Create aliases .bash_aliases file, Example:
alias startobi='sh $ORACLE_BI_HOME/bitools/bin/start.sh'
alias stopobi='sh $ORACLE_BI_HOME/bitools/bin/stop.sh'

Disable firewall
systemctl disable firewalld.

.bash_profile example

Sometimes, operative systems users don't come with bash profile file, here you have an example of
this file and common environment variables in a Oracle installation.


# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export PATH

# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP

export ORACLE_HOSTNAME=cbaf0b
export ORACLE_UNQNAME=cloudcdb1
export ORACLE_BASE=/mnt/opc_data
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_SID=cloudcdb1

export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

export JAVA_HOME=/usr/java/jdk1.8.0_91
export JRE_HOME=/usr/java/jdk1.8.0_91/jre
export JDK_HOME=/usr/java/jdk1.8.0_91

export PATH=$JAVA_HOME/bin:$PATH

Install APEX 4.2 in OLS 6

Helo guys, Now we are going to install APEX 4.02  in OLS 6

There are two ways to install it.

1.- When you have install the database with this option.
2.- When you don't.

Here we are going to use the first option.

The database:

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Partitioning, Oracle Label Security, OLAP, Advanced Analytics
and Real Application Testing options

1.- Locate the database home, in my case:

/u01/app/oracle/product/12c/db_1

2.- Search if you have de apex folder

[oracle@alexdb db_1]$ ls

addnode      dbs            javavm   odbc         precomp       sqlpatch

apex         dc_ocm         jdbc     olap         QOpatch       sqlplus

assistants   deinstall      jdk      OPatch       R             srvm

bin          demo           jlib     opmn         racg          suptools

ccr          diagnostics    ldap     oracore      rdbms         sysman

cdata        dmu            lib      oraInst.loc  relnotes      ucp

cfgtoollogs  dv             log      ord          rest          usm

clone        has            md       oui          root.sh       utl

crs          hs             mgw      owm          scheduler     wwg

css          install        network  perl         slax          xdk

ctx          instantclient  nls      plsql        sqldeveloper

If you don't have it, you must download it from:

http://www.oracle.com/technetwork/developer-tools/apex/downloads/index.html

3.- Run script 

@apex_epg_config.sql /u01/app/oracle/product/12c/db_1

4.- Run script

@apxconf.sql

Voilá!

Notes:

Please be sure you have this users unlocked and not expired: Example: If EXPIRED - Change password for following users : ANONYMOUS,XDB,APEX_PUBLIC_USER
,FLOWS_FILES,APEX_040200.
IF LOCKED - Unlock: ALTER USER ANONYMOUS ACCOUNT UNLOCK; ALTER USER XDB ACCOUNT UNLOCK; ALTER USER APEX_PUBLIC_USER ACCOUNT UNLOCK; ALTER USER FLOWS_FILES ACCOUNT UNLOCK; ALTER USER APEX_040200 ACCOUNT UNLOCK; SQL > ALTER USER ANONYMOUS IDENTIFIED BY anonymous; SQL> ALTER USER ANONYMOUS ACCOUNT UNLOCK; SQL> ALTER USER XDB IDENTIFIED BY xdb; SQL> ALTER USER XDB ACCOUNT UNLOCK;

That's because APEX is going to prompt you about XDB Credentials if something is wrong

Enlarge a Virtual Disk in VirtualBox VDI

If you have a Virtual Machine and you have created it with fixed size, but in some cases the size you gave it a space less than you need, that's why you have to enlarge it.

The big picture steps:

Enter the path where you have installed your Vbox (Windows in my case)

cd C:\Program Files\Oracle\VirtualBox

Issue this command:

VBoxManage modifyhd "C:\Users\Alejandro\VirtualBox VMs\OL6.6_em12c_db\OL6.6.vdi" --resize 51200

Once you have done that, start your virtual machine (linux in my case)

with root issue this command:

Let's add the space to existing virtual disk

fdisk /dev/sda

- Options n,p,3

"Command (m for help): n
