# Oracle by ODBC
## Overview
The template is developed to monitor a single DBMS Oracle Database instance with ODBC and can monitor CDB or non-CDB installations.
## Requirements
Zabbix version: 7.0 and higher.
## Tested versions
This template has been tested on:
- Oracle Database 12c2, 18c, 19c
## Configuration
> Zabbix should be configured according to the instructions in the [Templates out of the box](https://www.zabbix.com/documentation/7.0/manual/config/templates_out_of_the_box) section.
## Setup
1. Create an Oracle DB user for monitoring:
In CDB installations it is possible to monitor tablespaces from CDB _(container database)_ and all PDBs _(pluggable databases)_. In such case, a common user is needed with the correct rights:
```
CREATE USER c##zabbix_mon IDENTIFIED BY <PASSWORD>;
-- Grant access to the c##zabbix_mon user.
ALTER USER c##zabbix_mon SET CONTAINER_DATA=ALL CONTAINER=CURRENT;
GRANT CONNECT, CREATE SESSION TO c##zabbix_mon;
GRANT SELECT_CATALOG_ROLE to c##zabbix_mon;
GRANT SELECT ON v_$instance TO c##zabbix_mon;
GRANT SELECT ON v_$database TO c##zabbix_mon;
GRANT SELECT ON v_$sysmetric TO c##zabbix_mon;
GRANT SELECT ON v_$system_parameter TO c##zabbix_mon;
GRANT SELECT ON v_$session TO c##zabbix_mon;
GRANT SELECT ON v_$recovery_file_dest TO c##zabbix_mon;
GRANT SELECT ON v_$active_session_history TO c##zabbix_mon;
GRANT SELECT ON v_$osstat TO c##zabbix_mon;
GRANT SELECT ON v_$restore_point TO c##zabbix_mon;
GRANT SELECT ON v_$process TO c##zabbix_mon;
GRANT SELECT ON v_$datafile TO c##zabbix_mon;
GRANT SELECT ON v_$pgastat TO c##zabbix_mon;
GRANT SELECT ON v_$sgastat TO c##zabbix_mon;
GRANT SELECT ON v_$log TO c##zabbix_mon;
GRANT SELECT ON v_$archive_dest TO c##zabbix_mon;
GRANT SELECT ON v_$asm_diskgroup TO c##zabbix_mon;
GRANT SELECT ON sys.dba_data_files TO c##zabbix_mon;
GRANT SELECT ON DBA_TABLESPACES TO c##zabbix_mon;
GRANT SELECT ON DBA_TABLESPACE_USAGE_METRICS TO c##zabbix_mon;
GRANT SELECT ON DBA_USERS TO c##zabbix_mon;
```
This is needed because the template uses ```CDB_*``` views to monitor tablespaces from CDB and different PDBs, and, therefore, the monitoring user needs access to the container data objects on all PDBs.
However, if you wish to monitor only a single PDB or non-CDB instance, a local user is sufficient:
```
CREATE USER zabbix_mon IDENTIFIED BY <PASSWORD>;
-- Grant access to the zabbix_mon user.
GRANT CONNECT, CREATE SESSION TO zabbix_mon;
GRANT SELECT_CATALOG_ROLE to zabbix_mon;
GRANT SELECT ON v_$instance TO zabbix_mon;
GRANT SELECT ON v_$database TO zabbix_mon;
GRANT SELECT ON v_$sysmetric TO zabbix_mon;
GRANT SELECT ON v_$system_parameter TO zabbix_mon;
GRANT SELECT ON v_$session TO zabbix_mon;
GRANT SELECT ON v_$recovery_file_dest TO zabbix_mon;
GRANT SELECT ON v_$active_session_history TO zabbix_mon;
GRANT SELECT ON v_$osstat TO zabbix_mon;
GRANT SELECT ON v_$restore_point TO zabbix_mon;
GRANT SELECT ON v_$process TO zabbix_mon;
GRANT SELECT ON v_$datafile TO zabbix_mon;
GRANT SELECT ON v_$pgastat TO zabbix_mon;
GRANT SELECT ON v_$sgastat TO zabbix_mon;
GRANT SELECT ON v_$log TO zabbix_mon;
GRANT SELECT ON v_$archive_dest TO zabbix_mon;
GRANT SELECT ON v_$asm_diskgroup TO zabbix_mon;
GRANT SELECT ON sys.dba_data_files TO zabbix_mon;
GRANT SELECT ON DBA_TABLESPACES TO zabbix_mon;
GRANT SELECT ON DBA_TABLESPACE_USAGE_METRICS TO zabbix_mon;
GRANT SELECT ON DBA_USERS TO zabbix_mon;
```
**Note! Ensure that ODBC connects to Oracle with session parameter NLS_NUMERIC_CHARACTERS= '.,'. It is important for displaying the float numbers in Zabbix correctly.**
2. Install the ODBC driver on Zabbix server or Zabbix proxy.
See the [Oracle documentation](https://www.oracle.com/database/technologies/releasenote-odbc-ic.html) for instructions.
3. Configure Zabbix server or Zabbix proxy for the usage of Oracle Environment:
This step is required only when:
* installing Oracle Instant Client with .rpm packages with version < 19.3 (if Instant Client is the only Oracle Software installed on Zabbix server or Zabbix proxy);
* installing Oracle Instant Client manually with .zip files.
There are multiple ways of achieving this:
1. Using `LDCONFIG` utility **(recommended option)**:
To update the runtime link path, it is recommended to use the ```LDCONFIG``` utility, for example:
```
# sh -c "echo /opt/oracle/instantclient_19_18 > /etc/ld.so.conf.d/oracle-instantclient.conf"
# ldconfig
```
2. Using application configuration file:
An alternative solution is to export the required variables by editing or adding a new application configuration file:
* ```/etc/sysconfig/zabbix-server # for server```
* ```/etc/sysconfig/zabbix-proxy # for proxy```
And then, adding:
```
# Oracle Instant Client library
LD_LIBRARY_PATH=/opt/oracle/instantclient_19_18:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
```
Keep in mind that the library paths will vary depending on your installation.
This is a minimal configuration example. Depending on the Oracle Instant Client version, required functionality and host operating system, a different set of additional packages might need to be installed.
For more detailed configuration instructions, see the [official Oracle Instant Client installation instructions for Linux](https://www.oracle.com/database/technologies/instant-client/linux-x86-64-downloads.html).
4. Restart Zabbix server or Zabbix proxy.
5. Set the username and password in the host macros ({$ORACLE.USER} and {$ORACLE.PASSWORD}).
6. Set the {$ORACLE.DRIVER} and {$ORACLE.SERVICE} in the host macros.
* ```{$ORACLE.DRIVER}``` is a path to the driver location in OS. The ODBC driver file should be found in __Instant Client__ directory and named ```libsqora.so.XX.Y```.
* ```{$ORACLE.SERVICE}``` is a service name to which the host will connect to. The value in this macro is important as it determines if the connection is established to a non-CDB, CDB or PDB. If you wish to monitor tablespaces of all PDBs, you will need to set a service name that points to the CDB.
Active service names can be seen from the instance running Oracle Database with ```lsnrctl status```.
**Note! Make sure that the user created in step #1 is present on the specified service.**
The "Service's TCP port state" item uses ```{HOST.CONN}``` and ```{$ORACLE.PORT}``` macros to check the availability of the listener.

In the case of modifying data transactions, it sequentially temporarily blocks the right to change the data, the rest of the transactions are waiting for the access. In the case when the access for the resource is locked for a long time, then the concurrency grows (like the transaction queue) and this often has an extremely negative impact on the performance.
