ggsci: error while loading shared libraries: libnnz12.so

[gguser@Linux03 OGGHOME]$ ggsci
ggsci: error while loading shared libraries: libnnz12.so: cannot open shared object file: No such file or directory


ONE REASON THIS CAN HAPPEN IS IF GGSCI CANT FIND/ACCESS libnnz12.so FILE :

[gguser@Linux03 OGGHOME]$ cd $ORACLE_HOME
[gguser@Linux03 db_1]$ cd lib
[gguser@Linux03 lib]$ ls -ll libnnz12.so
-rw-r--r--. 1 oracle oracle 6213011 Jun 18  2014 libnnz12.so

Note: Sometimes it can also be missing or wrong permissions on files.



***************************************************************
IMPORTANT PATH SETTINGS TO CHECK FOR :
***************************************************************

$ export OGGHOME=/u01/app/OGGHOME        ### Where OGGHOME is where the GG                                                                                                             binaries are installed
$ export PATH=$PATH:$OGGHOME 
$ export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$OGGHOME


Note : There is another way to deal te same problem is to create a symbolic link to this file libnnz12 under ORACLE_HOME/lib


CHECK IF THE PATHS ARE SET CORRECT, IN MY CASE MY ORACLE HOME WAS NOT SET RIGHT. WHICH MADE DEPENDENT PATHS FAIL:

[gguser@Linux03 OGGHOME]$ echo $ORACLE_HOME
/u01/app/oracle/product/12.1.0.1/db_1

[gguser@Linux03 OGGHOME]$ cd $ORACLE_HOME

Previous versions of GG use to be cmd line installation. But now we can use GUI for this. If you want to to do silent Installation follow this link GG-Silent-instalaltion

Once the Software is unzipped you can change directory to runInstaller and invoke installer.

 invoke by calling ./runInstaller

 

Software Location : This will be the location where you want to install oracle Golden Gate Binaries.
Database Location : This will the Oracle Home  directory of Source Database
manager port :7809 by default (you can also select a diff port but I would suggest to leave it as is)

Make sure the locations are correct and click Install.

Once the GG software is installed you will see the GG related files in GG HOME directory.

GGSOURCE IS THE PASSWORD FOR USER GGSOURCE (DB USER)

Login as ggsci user:

Using Blowfish encryption with DEFAULT key.
Encrypted password:  AACAAAAAAAAAAALAXCJHZHLEZAKGMFABMBWBEJLFHCRHABJGYI  --> This is encrypted value
Algorithm used:  BLOWFISH

[gguser@Linux03 OGGHOME]$ mkdir dirinc
[gguser@Linux03 OGGHOME]$ vi ./dirinc/ggtarget.inc


We can create a  include file to use it for our future references.

GoldenGate Silent Installation

under maintenance ..

You do not have sufficient permissions to access the inventory '/u01/app/oraInventory'

[gguser@Linux03 Disk1]$ ./runInstaller

You do not have sufficient permissions to access the inventory '/u01/app/oraInventory'. Installation cannot continue. It is required that the primary group of the install user is same as the inventory owner group. Make sure that the install user is part of the inventory owner group and restart the installer.: Permission denied

[gguser@Linux03 Disk1]$ ls -ll /u01/app/oraInventory
ls: cannot open directory /u01/app/oraInventory: Permission denied

CHECKING THE GROUPS ON oraInventory:

[root@Linux03 Desktop]# ls -all /u01/app/oraInventory
total 28
drwxrwx---. 5 oracle oracle   4096 Feb 29 15:24 .
drwxrwxr-x. 7 oracle oinstall 4096 Apr 13 14:40 ..
drwxrwx---. 2 oracle oracle   4096 Feb 29 15:24 ContentsXML

-rwxrwx---. 1 oracle oracle   1612 Feb 29 15:24 orainstRoot.sh
drwxrwx---. 2 oracle oracle   4096 Feb 29 15:21 oui

Solution :

CHANGED GGUSER primary Group to oracle which is the primary group for oracle user. In my case oraInventory was under oracle group.

DOWNLOAD AND UNZIP GG SOFTWARE - STEP 2

I WILL BE CALLING ORACLE GOLDEN GATE AS OGG THRU THIS TUTORIAL

You can download the oracle GG software from below link :

http://www.oracle.com/technetwork/middleware/goldengate/downloads/index.html

 

You will need an oracle account for this. This is a free account, so if you don't have one you can register for one.

I have downloaded it from above link.In my case I have to download software for Linuxx86-64 as this will be my host OS and oracle 12c is my source DB.

[gguser@Linux03 Desktop]$ cd
[gguser@Linux03 ~]$ pwd

[gguser@Linux03 OGG_SFTW]$ cp fbo_ggs_Linux_x64_shiphome.zip /u01/app/GGHOME

JUST TO MAKE LIFE SIMPLE export GGHOME PATH SO WE CAN USE IT IN FUTURE:

[gguser@Linux03 GGHOME]$ echo $GGHOME

Create the new groups and user for GoldenGate sofwtare. - STEP -1

This is an optional setup. By doing this you can separate the golden gate user access from other users like oracle, RAC user etc. While some prefer to have GG software installed with in oracle user. I like to have it separated.

Create the new groups and user for GoldenGate replication sofwtare.

groupadd ggowner  ## Adding new group ggowner
useradd -g ggowner -G dba,oper gguser ## Adding new user gguser & add to groups default ggowner additional dba,oper,oinstall

WE CAN QUERY THESE NEW USERS IN LINUX:

[root@Linux03 Desktop]# cat /etc/passwd |grep gguser
gguser:x:501:501:golden gate user:/home/gguser:/bin/bash
gguser1:x:502:54331::/home/gguser1:/bin/bash

LOGIN AS NEW USER :

[root@Linux03 Desktop]# su gguser

CHECK THE GROUPS GGUSER IS PART OF :

[gguser@Linux03 Desktop]$ id
