Oracle SQL Network Test

User – In order to monitor an Oracle database server, a special database user account has to be created in every Oracle database instance that requires monitoring. A Click here hyperlink is available in the test configuration page, using which a new oracle database user can be created. Alternatively, you can manually create the special database user. When manually creating a user on an Oracle database server before version 10G, ensure that the select_catalog_role and create session privileges are granted to the user. When monitoring an Oracle database server 10G (and above), this test additionally requires select privileges to the sys.user$ table.

The sample script we recommend for user creation (in Oracle database server versions before 10G) for eG monitoring is:

create user oraeg identified by oraeg

create role oratest;

grant create session to oratest;

grant select_catalog_role to oratest;

grant oratest to oraeg;

The sample script we recommend for user creation (in Oracle database server version 10G and 11G) for eG monitoring is:

create user oraeg identified by oraeg

create role oratest;

grant create session to oratest;

grant select_catalog_role to oratest;

Grant select on sys.user$ to oratest;

grant oratest to oraeg;

The sample script we recommend for user creation (in Oracle database server 12c) for eG monitoring is:

alter session set container=<Oracle_service_name>;

create user <user_name>identified by <user_password> container=current default tablespace <name_of_default_tablespace> temporary tablespace <name_of_temporary_tablespace>;

Grant create session to <user_name>;                                

Grant select_catalog_role to <user_name>;

Grant select on sys.user$ to <user>;

The name of this user has to be specified here.

QUERY - By default, this parameter is set to none. This implies that the eG agent monitors the responsiveness and availability of the database server based on the default query that has been hard-coded. However, sometimes, you may wish to monitor server's availability and responsiveness for a critical query of your choice. To achieve this, you can specify the critical query against this parameter by overriding the default value. Note that you can configure only a single SELECT query for this parameter.

Note:

To execute the SELECT query, the User should have the select privilege.

TRUSSTORE PASSWORD-This parameter is applicable only if the target Oracle database is SSL-enabled, if not, set this parameter to none. If a Truststore File name is provided, then, in this text box, provide the password that is used to obtain the associated certificate details from the Truststore File. By default, this parameter is set to none.

DETAILED DIAGNOSIS – To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

• The eG manager license should allow the detailed diagnosis capability
• Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
