Option to disable NLS query

[Zegorax]

Ciao,

I'm using the Telegraf inputs.sql (https://github.com/influxdata/telegraf/tree/master/plugins/inputs/sql) plugin with go_oracle (v2) to connect to an active/standby Oracle instance. I noticed one problem that I cannot go around when it is connecting.

Prior to executing any statement, it is executing the following request:

        BEGIN
                SELECT
                        MAX(CASE WHEN PARAMETER='NLS_CALENDAR' THEN VALUE END) AS NLS_CALENDAR,
                        MAX(CASE WHEN PARAMETER='NLS_COMP' THEN VALUE END) AS NLS_COMP,
                        MAX(CASE WHEN PARAMETER='NLS_LENGTH_SEMANTICS' THEN VALUE END) AS NLS_LENGTH_SEMANTICS,
                        MAX(CASE WHEN PARAMETER='NLS_NCHAR_CONV_EXCP' THEN VALUE END) AS NLS_NCHAR_CONV_EXCP,
                        MAX(CASE WHEN PARAMETER='NLS_DATE_LANGUAGE' THEN VALUE END) AS NLS_DATE_LANGUAGE,
                        MAX(CASE WHEN PARAMETER='NLS_SORT' THEN VALUE END) AS NLS_SORT,
                        MAX(CASE WHEN PARAMETER='NLS_CURRENCY' THEN VALUE END) AS NLS_CURRENCY,
                        MAX(CASE WHEN PARAMETER='NLS_DATE_FORMAT' THEN VALUE END) AS NLS_DATE_FORMAT,
                        MAX(CASE WHEN PARAMETER='NLS_ISO_CURRENCY' THEN VALUE END) AS NLS_ISO_CURRENCY,
                        MAX(CASE WHEN PARAMETER='NLS_NUMERIC_CHARACTERS' THEN VALUE END) AS NLS_NUMERIC_CHARACTERS,
                        MAX(CASE WHEN PARAMETER='NLS_DUAL_CURRENCY' THEN VALUE END) AS NLS_DUAL_CURRENCY,
                        MAX(CASE WHEN PARAMETER='NLS_TIMESTAMP_FORMAT' THEN VALUE END) AS NLS_TIMESTAMP_FORMAT,
                        MAX(CASE WHEN PARAMETER='NLS_TIMESTAMP_TZ_FORMAT' THEN VALUE END) AS NLS_TIMESTAMP_TZ_FORMAT
                        into :p_nls_calendar, :p_nls_comp, :p_nls_length_semantics, :p_nls_nchar_conv_excep,
                                :p_nls_date_lang, :p_nls_sort, :p_nls_currency, :p_nls_date_format, :p_nls_iso_currency,
                                :p_nls_numeric_chars, :p_nls_dual_currency, :p_nls_timestamp, :p_nls_timestamp_tz
                FROM
                        sys.nls_session_parameters
                ;
        END;

(From the "trace log" URL parameter)
This will result in : PL/SQL: ORA-01219: database not open: queries allowed on fixed tables/views only since the database is in standby mode, and therefore I cannot execute my query.

Since I'm using the Telegraf plugin, I cannot use the SessionParameter that I've seen in the code that could disable this check. Only the URL connection string is used (oracle://user:pass@host/instance?dba%20privilege=SYSDBA).

I've tried as well to add &language=AMERICAN&territory=AMERICA in the URL as an example, but it is not working either.

Is there a possibility to disable this NLS retrieve check via an environment variable or other URL option for example ?

Thanks a lot in advance!
