What is already available in the Shinken Installation

To make your life a bit easier, a few configuration tasks have already been done for you:

1. Installation of Oracle instant Client
2. Installation of check_oracle_health plugin : /var/lib/shinken/libexec/check_oracle_health
3. Several host templates are ready to be used

Setup the oracle user account

Create the database user
 

Connect to your database as sysadmin on the oracle server :

Code Block srv-lin-1:oracle# sqlplus "/ as sysdba"

And then create your shinken account on the database:

Code Block language sql CREATE USER shinken IDENTIFIED BY shinkenpassword; GRANT CREATE SESSION TO shinken; GRANT SELECT any dictionary TO shinken; GRANT SELECT ON V_$SYSSTAT TO shinken; GRANT SELECT ON V_$INSTANCE TO shinken; GRANT SELECT ON V_$LOG TO shinken; GRANT SELECT ON SYS.DBA_DATA_FILES TO shinken; GRANT SELECT ON SYS.DBA_FREE_SPACE TO shinken;

And for old 8.1.7 database only:

Code Block language sql ---- if somebody still uses Oracle 8.1.7... GRANT SELECT ON sys.dba_tablespaces TO shinken; GRANT SELECT ON dba_temp_files TO shinken; GRANT SELECT ON sys.v_$Temp_extent_pool TO shinken; GRANT SELECT ON sys.v_$TEMP_SPACE_HEADER TO shinken; GRANT SELECT ON sys.v_$session TO shinken;

Test the connection

To see if the connection to the database named PROD is ok, just launch :

	Code Block language bash /var/lib/shinken/libexec/check_oracle_health --connect "(DESCRIPTION =(ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = srv-lin-1)(PORT = 1521)))(CONNECT_DATA =(SID = PROD)))" --user "shinken" --password "shinkenpassword" --mode connection-time

Manage more than 1 database on the same host

All checks presents in Oracle templates provided by Shinken Entreprise use the "Duplicate For Each" functionality.

For each database name listed in the DATA "DATABASES", check will be duplicated. An host, having 2 databases, will then have in double each checks with the datatabase name in the check.

If you need to set a specific port of connection for 1 of the database, you can provide it as parameters of the Database:
