netxms with oracle 10+ backend

[andrey--k]

checkinstall - debian utility which does make install and creates deb package

[andrey--k]

just tried make install - finished without errors

[victor]

Looks like checkinstall cannot handle it correctly. make install supposed to install nxmibc and after that post installation hook is called which will compile MIBs using just installed nxmibc.

Best regards,

hi Victor,

i am using NetXMS 1.2.11 with Postgres as Backend database. it is  working Properly. now i have another test machine with Oracle as Backend Database but netxms is not able to connect to the Oracle Database. it shows the error message like

Unable to Connect to database : ORA-12504: TNS:listener was not given the SERVICE_NAME in CONNECT_DATA

Machine Details
OS- Windows Server 2008 r2 64 Arch,
RAM - 16GB,
Database - Oracle 11g
NetXMS 1.2.11

Thanks
Percy

Hi!

Seems that you've made a mistake in configuration. Please provide your netxmsd.conf and Oracle server parameters (address and service name). Also, what Oracle client you are using?

Best regards,
Victor

hi victor,
Sorry for the late reply . i have attached the netxmsd.conf, tnsnames.ora, Listener.ora file.
when i start Server Configuration Wizard to select the Data base Engine i selct the Oracle than Create new database become disable.
in case of Postgresql netxms create its database names Netxms_db and its required schema. why in case of oracle create new database become Disable.

thank you
Percy

netxmsd.conf

tnsnames.ora

listener.ora

For Oracle you have to create database user manually (and this will create schema) and choose "existing database" option.

If you are using InstantClient you should specify Oracle connection string in DBServer parameter in form //server_ip/service_name

To do initialization manually, follow these steps:

1. Connect to Oracle server with sqlplus as sysdba:

C:\Source\NetXMS\x64\debug>sqlplus sys/admin@//192.168.64.3 as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Wed Feb 19 11:41:37 2014

Copyright (c) 1982, 2010, Oracle.  All rights reserved.


Connected to:
Oracle Database 10g Express Edition Release 10.2.0.1.0 - Production

SQL>

2. Create user and grant necessary rights:

SQL> create user netxms identified by netxms;

User created.

SQL> grant create session to netxms;

Grant succeeded.

SQL> grant resource to netxms;

Grant succeeded.

SQL> grant create view to netxms;

Grant succeeded.

SQL>

3. Set correct values in netxmsd.conf. In my case it will be

DBDriver = oracle.ddr
DBServer = //192.168.64.3/XE

DBLogin = netxms
DBPassword = netxms

4. Initialize database:

C:\Source\NetXMS\x64\debug>nxdbmgr init ..\..\sql\dbinit_oracle.sql
NetXMS Database Manager Version 1.2.12 Build 7861

Initializing database...
Database initialized successfully

C:\Source\NetXMS\x64\debug>

Also, it seems that initialization script shipped with NetXMS installer may contain errors and database initialization will fail with "cannot insert NULL" error. In that case, please use attached initialization script.

Best regards,
Victor

Looks like missing dependencies or not included library:

Configuration Debian 7.4, Oracle 11_2 on separate server.

You have to install Oracle client manually because it's not an open source software and there are no package in Debian repository for it. I recommend using Instant Client (http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html) version 11.2.0.4.0. Recommended location - /opt/instantclient_11_2.

TO WIKI:
Debian 7
Oracle 11.2g on separate server:

#less /etc/netxmsd.conf

DBDriver = /usr/lib/netxms/dbdrv/oracle.ddr
DBServer = ServerIP/Hostname.DomainName #Here is service (full database name), not SID
DBName = netxms
DBLogin = netxms
DBPassword = PaSwD

download from oracle web:
instantclient-basic-linux.x64-11.2.0.4.0
unpak into /opt/instantclient_11_2

create file
less /etc/ld.so.conf.d/oracle.conf

/opt/instantclient_11_2

Reload the list of system-wide library paths:

ldconfig

on oracle:

-- USER SQL
CREATE USER netxms IDENTIFIED BY netxms
DEFAULT TABLESPACE USERS
TEMPORARY TABLESPACE TEMP;
-- QUOTAS
ALTER USER netxms QUOTA UNLIMITED ON USERS;
-- ROLES
GRANT RESOURCE TO netxms ;
GRANT CONNECT TO netxms ;

on Debian:

nxdbmgr init /usr/share/netxms/sql/dbinit_oracle.sql

if next errors appeared:

!!! here is changed admin as full username and whitespace as sertificate

before rerunning nxdbmgr init i have made drop and create user once more.
