PowerCenter - Installation and Configuration (9.0.1 for OEL Linux 64Bit)

1 - About

This article talk about the installation of PowerCenter from Informatica on:

  • Oracle Entreprise Linux 64 bit version 5 Update 5
  • Oracle Database 11gR2

I have made it in the context of an Oracle Business Intelligence Application version 7.9.6.1 installation (on Linux) then it's why the computer name is di-obia-01.

After you complete the installation and configuration process, you have to log in to the Administrator tool to create and configure the following services:

  • PowerCenter Repository Service
  • PowerCenter Integration Service

3 - Prerequisites

3.1 - The platform

3.2 - Download the files

The files for the software Informatica PowerCenter and PowerConnect Adapters 9.0.1 are available on Edelivery.com

Choose:

  • Oracle Business Intelligence on Linux x86_64 and click Go
  • You must download this files:

The file “Informatica PowerCenter and PowerConnect Adapters Client 9.0.1” contains:

  • the Windows Client
  • the documentation
  • the license key

The part 1 and 2 are multipart archive (.z01, .zip), you can use WinZip or Winrar to decompress it

The file “Informatica PowerCenter and PowerConnect Adapters 9.0.1 for Linux x86 (64-bit)” contains:

  • the server
  • the patch

The Oracle key (File2>Oracle_All_OS_Prod.key) is not valid for the installation of :

3.3 - Oracle Database

3.3.1 - parameter

Set the open_cursors parameter to 1000

SQL> SHOW parameter open_cursor;
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
open_cursors                         INTEGER     300
SQL> ALTER system SET open_cursors=1000;
 
System altered.
 
SQL>  ALTER system SET open_cursors=1000 SCOPE=BOTH;
 
System altered.
 
SQL> SHOW parameter open_cursors;
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
open_cursors                         INTEGER     1000

3.3.2 - Repository Account

At least two database user accounts are required to host this repository :

  • POW_REP for the repository Database
  • POW_DOM fro the domain Configuration Database

with the CONNECT, RESOURCE, and CREATE VIEW privileges.

For Oracle, you must perform the following instruction :

CREATE USER POW_REP IDENTIFIED BY POW_REP 
DEFAULT tablespace users
TEMPORARY tablespace temp
quota unlimited ON users;
 
GRANT CONNECT, resource, CREATE VIEW TO POW_REP;
 
CREATE USER POW_DOM IDENTIFIED BY POW_DOM 
DEFAULT tablespace users
TEMPORARY tablespace temp
quota unlimited ON users;
 
GRANT CONNECT, resource, CREATE VIEW, SELECT ANY dictionary TO POW_DOM;

The grant “select dictionary privilege” to the user POW_DOM is only needed to verify the parameter Open_Cursor during the prerequisite check.

3.3.3 - Repository Tablespace

Set the storage size for the tablespace to a small number to prevent the repository from using an excessive amount of space.

Also verify that the default tablespace for the user that owns the repository tables is set to a small size. The following example shows how to set the recommended storage parameter for a tablespace named POWERCENTER_DAC.

ALTER TABLESPACE "POWERCENTER_DAC" DEFAULT STORAGE ( INITIAL 10K NEXT 10K MAXEXTENTS UNLIMITED
PCTINCREASE 50 );

3.4 - Operating System

Login as root

3.4.1 - Processor

Verify that the process match the software (x86_64)

[[email protected] ~]# uname -p
x86_64
[[email protected] ~]# uname -orv
2.6.18-194.el5 #1 SMP Mon Mar 29 22:10:29 EDT 2010 GNU/Linux

3.4.2 - Temporary Disk Space Requirements

The installer writes temporary files to the hard disk. When the installation completes, the installer deletes the temporary files and releases the disk space.

Installer UNIX 1 GB
Informatica Services UNIX 2 GB

Verification of the temporary space with the df commando: Linux - disk free command (df)

[[email protected] ~]# df -h /tmp
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                       77G   16G   58G  22% /

3.4.3 - User Account

On UNIX, create a user account specifically to run the Informatica daemon.

[[email protected] ~]# /usr/sbin/useradd powercenter
[[email protected] ~]# id powercenter
uid=502(powercenter) gid=506(powercenter) groups=506(powercenter)
[[email protected] ~]# passwd powercenter
Changing password for user powercenter.
New UNIX password:
BAD PASSWORD: it is WAY too short
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

3.4.4 - Port

Verify that the port numbers are available on the machines where you install Informatica Services.

[[email protected] ~]# netstat -tulpn|grep 6005

The installer validates the port numbers that you specify to ensure that there will be no port conflicts in the domain.

3.4.5 - Environment Variables

Use LANG and LC_ALL to set the UNIX code page for the installer.

3.4.6 - File Descriptor

Informatica service processes can use a large number of files. Set the file descriptor limit per process to 3000 or higher.

In the file /etc/security/limits.conf, add this line:

# PowerCenter 
powercenter    hard   nofile    3001
powercenter    soft   nofile    2500

And verify with the ulimit function logged as the powercenter system user account:

[[email protected] ~]$ ulimit -Hn
3001

The limit is set to 3001 to prevent an error with the value 300 during the prerequisites check ;-)

3.4.7 - Installation directory and Permission

As root, create the installation base directory:

mkdir -p /powercenter/9.0.1
chown -R powercenter:powercenter /powercenter
chown -R powercenter:powercenter /powercenter/9.0.1
chmod -R 775 /powercenter
chmod -R 775 /powercenter/9.0.1

As the installer (powercenter), copy the file to a tmp directory, unzip and untar it:

[[email protected] powercenter901]$ unzip V26109-01.zip
Archive:  V26109-01.zip
  inflating: 901HF2_Server_Installer_linux-x64.tar
[[email protected] powercenter901]$ tar -xf 901HF2_Server_Installer_linux-x64.tar

Change the permission of the file install.sh to execute

chmod -R 744 /tmp/powercenter901/install.sh

4 - Server

4.1 - Pre-Installation System Check

To verify whether a machine meets the system requirements for an Informatica installation, run the Pre-Installation System Check Tool (i9Pi) before you start the installation process.

You can find the i9Pi tool in the following directory: <InstallerExtractDirectory>/i9Pi

[[email protected] i9Pi]$ ./i9Pi.bin
Preparing to install...
Extracting the JRE from the installer archive...
Unpacking the JRE...
Extracting the installation resources from the installer archive...
Configuring the installer for this system's environment...

Launching installer...

Enter the port 6004 to prevent a problem during the ckeck on the port 2010. The tool normally must verify until the port 6009 but check also the port 6010 which is the standard port for X Forwarding

A pdf is available in the tool directory if you want more information.

The report files are stored in the directory where you extract the Pre-Installation System Check tool files:

  • HTML format: <i9Pi Directory>/i9Pi/i9Pi_summary.html
  • Text format: <i9Pi Directory>/i9Pi_summary.log

i9Pi_summary.log
