Moving from NNMi using Postgres to NNMi with Oracle

This is a Draft Article

I just want to share my experience related to the migration from NNMi using local DB (postgress) to NNMi using Oracle DB

System was as specified:

NNMi 9.00 with Patch 1

Same Machine hosting the Embedded database (postgress)

Objective:

Migrate the configuration data to NNMi and Oracle Database.

Step X Backup NNMi for disaster recovery

nnmbackup.ovpl –type offline –scope all –force –archive –target c:\

a file with tar extension will be created on  drive c:\ started nnm-bak- and the current date and time .tar like nnm-bak-20100721183731.tar

Extra-Step X Backup any custome scripts you created for Incident actions.

%NnmDataDir%\shared\nnm\actions

aslo these files can be found under your backup archive

nnm-bak-20100721183731.tar\nnm-bak-20100721183731\data\shared\nnm\actions

Step X Backup you configuration (configuration Export)

in this step we will export the configuration using nnmconfigexport.ovpl

nnmconfigexport.ovpl –c all –file c:\exportedconfig

Hint: the export export remember to create the folder before run the above command “mkdir c:\exportedconfig”

Step X export Nodes as seed file

 

Step X Remove current NNMi installation

1st - Remove i-SPI

2nd – Remove Patches

3rd – Remove NNMi

Restart your server.

Step X Oracle configuration 

In this section we will create the table space that will hold the NNMi database that will be created during NNMi installation.

Section 1: Create Tablespace

CREATE SMALLFILE
    TABLESPACE "NNMI"
    LOGGING
    DATAFILE 'H:\ORADATA\NNMIDB\NNMI01.dbf' SIZE 4096M,
    'H:\ORADATA\NNMIDB\NNMI02.dbf' SIZE 4096M,
    'H:\ORADATA\NNMIDB\NNMI03.dbf' SIZE 4096M EXTENT MANAGEMENT
    LOCAL SEGMENT SPACE MANAGEMENT  AUTO

 

 

Section 2: Create NNMi User

CREATE USER "NNMI"  PROFILE "DEFAULT"
    IDENTIFIED BY "nnmi" DEFAULT TABLESPACE "NNMI"
    TEMPORARY TABLESPACE "TEMP"
    ACCOUNT UNLOCK;

 image Section 3: Assign Permissions for NNMi User

GRANT CREATE ANY INDEX TO "NNMI" ;
GRANT CREATE ANY SEQUENCE TO "NNMI" ;
GRANT CREATE ANY TABLE TO "NNMI" ;
GRANT CREATE ANY VIEW TO "NNMI" ;
GRANT CREATE SEQUENCE TO "NNMI";
GRANT CREATE SESSION TO "NNMI" ;
GRANT CREATE TABLE TO "NNMI" ;
GRANT CREATE VIEW TO "NNMI" ;
GRANT FLASHBACK ANY TABLE TO "NNMI" ;
GRANT "CONNECT" TO "NNMI";
GRANT "OEM_ADVISOR" TO "NNMI";
GRANT "RESOURCE" TO "NNMI";

Step X Install NNMi 9.x

Install using the installation guide.

 

Step X Load old node list a seed files 

 

Step X Load Node Groups and Maps information

1- load Nodegroup Map configuration

loading Nodegroup Map configuration will fail as per the screenshot but some required identification are imported that facilitate the nodegroup import

D:\Program Files (x86)\HP\HP BTO Software\bin>nnmconfigimport.ovpl  -f C:\export
edconfig\ngmap.xml

2- Load nodegroup configuration

D:\Program Files (x86)\HP\HP BTO Software\bin>nnmconfigimport.ovpl  -f C:\export
edconfig\nodegroup.xml
Successfully imported nodegroup.xml.

3- load Nodegroup Map Configuration again

D:\Program Files (x86)\HP\HP BTO Software\bin>nnmconfigimport.ovpl  -f C:\export
edconfig\ngmap.xml
Successfully imported ngmap.xml.
