How will I choose an institute for studying AWS?

I have exactly the same problem. I tried to solve it by installing libfbclients.so as described in https://freepascalanswers.wordpress.com/2012/11/19/firebird-library/
in my host Ubuntu server folder: /usr/lib/x86-64-linux-gnu/ I have these two files: libfbclient.so.2 and libfbclient.so.3.0.5
I also executed the command: sudo ln /usr/lib/x86_64-linux-gnu/libfbclient.so.2 /usr/lib/x86_64-linux-gnu/libfbclient.so
But I still can’t select my Firebird database in Dreamfactory to create APIs - I get the error message: Dreamfactory Utility Mode - could not find driver

On Ubuntu server, I created a Firebird installation by using the jacobalberty/firebird:latest image (version 3.0.7). From Windows, using IBExpert, I created a database on the Linux server and restored a backup.
I then use Dreamfactory in web browser, installed from bitnami/dreamfactory:latest image (version 4), to create a REST API by configuring a service for the populated database but when I select a the Firebird database as a DB Service I get the error message: “could not find driver”

Hi @arpiticx,

You are correct, DreamFactory can be load balanced across many instances, all of which share the same system database or database cluster. Getting Started with DreamFactory Chapter 9 presents a diagram depicting what this looks like.

The DreamFactory installers are useful for quickly installing and configuring a new DreamFactory instance. However they do not take into account a load balanced configuration. You could nonetheless use the installer for this purpose and just skip the php artisan df:setup step. Instead, you’ll copy your first DreamFactory instance’s .env file over to the newly installed instance. This is important because the .env file contains the APP_KEY value, database configuration settings, and any other settings which you might have configured.

After installing the DreamFactory instances, you’ll want to place them behind a load balancer. For instance, on AWS you might use an ALB (Application load balancer).

These days many DreamFactory users are gravitating towards Dockerized instances using DreamFactory’s Docker container (also see Dockerhub), as well as scaling using Kubernetes. Regarding Kubernetes, we’ve recently released a Helm Chart.

Hope this helps!

Hi @NolsSmit,

Can you please highlight the steps you have taken to install the Firebird driver? Were the steps you followed the ones highlighted in our Getting Started Guide?

Hi Kevin,

Ok, I now did follow the steps in Getting Started Guide.

I also edited /etc/php/7.4/cli/php.ini to:

..
..
;extension=odbc
;extension=openssl
extension=pdo_firebird
;extension=pdo_mysql
;extension=pdo_oci
...
...

On the command: $ php -m
I notice the following list of modules

I don’t recognize one Firebird related and I still get the same error: “Could not find driver” in DreamFactory Utility Mode

I followed these steps:

Start with:
$ sudo apt-get update

Install php
$ sudo apt install php7.4-cli

Install php dev
$ sudo apt install php7.4-dev

cd /tmp
git clone https://github.com/php/pecl-database-interbase.git
cd pecl-database-interbase/
sudo apt-get install firebird-dev autoconf build-essential
phpize --clean
phpize
./configure
make
sudo make install

Enable the driver in your /etc/php/7.4/cli/php.ini file.
cd /etc/php/7.4/cli sudo nano php.ini … and search for firebird

and change to
…
…
;extension=odbc
;extension=openssl
;extension=pdo_firebird
extension=interbase
;extension=pdo_mysql
;extension=pdo_oci
;extension=pdo_odbc
…
…

Jacob Alberty, owner of the jacobalberty/firebird image proposed the extension.

After saving the change in php.ini, with the command:
$ php -m

The output (without any error messages and notice interbase in the list) is:

nols@ubuntuserver:~$ php -m

Calling the POST execute procedure api.

I have an oracle stored procedure with two parameters. One parameter is an IN parameter and the other parameter is an OUT parameters.
CREATE OR REPLACE PROCEDURE up_test_out (p_in IN VARCHAR2,
p_out OUT VARCHAR2)
IS
BEGIN
p_out := p_in;
END up_test_out;
/

I get this error when the value of the OUT parameter exceeds 1 character.
{
“error”: {
“code”: 500,
“context”: null,
“message”: “Failed to call database stored procedure.\nError Code : 6502\nError Message : ORA-06502: PL/SQL: numeric or value error: character string buffer too small\nORA-06512: at “UPENN.UP_TEST_OUT”, line 5\nORA-06512: at line 1\nPosition : 0\nStatement : BEGIN “UPENN”.“UP_TEST_OUT”(:P_IN, :P_OUT); END;\nBindings : [test,]\n”,
“status_code”: 500
}
}

What am I doing wrong? I have tried various different calls and fiddling with the json sent in the request body. I feel like I’m missing something here.

Here is the json request body I am sending in the POST:

{
“params”: [
{
“name”: “p_in”,
“value”: “test”
}
],
“schema”: {
“p_out”: “string”
}
}

When I call it with this request body it works:

{
“params”: [
{
“name”: “p_in”,
“value”: “T”
}
],
“schema”: {
“p_out”: “string”
}
}

Response:
{
“P_OUT”: “T”
}

A similar issues exists if the parameter is IN OUT - in that instance it will work as long as the returning value does not exceed the length of value being sent in to the call.

I am having same issue in new deploy .

Hi there

I have the same problem! I am adding the ‘state’ param. Are you still using this? If so, do you have any more information?

Thank you!

Fixed by applying https://github.com/dreamfactorysoftware/df-oracledb/pull/9/commits/1c9b8e90e6d3eca95b9e9061d311c8959ae83977

Hello

I am hoping someone here can help me. I need auto-generate APIs to my PostgreSQL database. the database is hosted on my hosting provider shared server. I have to connect to it using SSH tunnels. Direct SSH access is not allowed.

I used the Bitnami Dreamfactory VM and got the instance up and running. On the terminal, I established an SSH tunnel connection to my hosting server. On the dreamfactory web interface, I created the Service to PostgreSQL but when I test on API Docs (Get /_Table), I get the following error:

“error”: {
“code”: “42P01”,
“message”: “SQLSTATE[42P01]: Undefined table: 7 ERROR: relation “pg_matviews” does not exist\nLINE 11: FROM pg_matviews\n ^ (SQL: SELECT all_views.table_name, all_views.table_schema\n FROM (\n SELECT table_name AS table_name,\n table_schema AS table_schema,\n table_type AS table_type\n FROM information_schema.tables\n UNION ALL\n SELECT matviewname AS table_name,\n schemaname AS table_schema,\n ‘VIEW’ AS table_type\n FROM pg_matviews\n ) AS all_views\n WHERE all_views.table_type = ‘VIEW’ AND table_schema = ‘public’)”
}
}

I have no wider why it is looking in the views table.

So either I am doing something wrong or I have not correctly connected to my postgreql database or I am connected buy but trying yo access system tables.

The strange this is when I try Get /_table/{table_name} and enter one of the tables I created I get the same error about pg_matviews.

Can someone help?

On the “Create New Services” page, I’m setting us a service and want to use SSL keys as part of the security model. I can see a place to provide the SSL mode (in my case, required) but there is no space to provide an SSL key.

I’ve two instances running - one connecting to a MySQL db and another to a PostgreSQL db - but do not see the input space for the certs.

Does anyone else have this issue? Or are only connections without certs available?

Thanks.

My service is created however, I am now trying to create a role to use the service. I am receiving the error:

Api Error

SQLSTATE[23000]: Integrity constraint violation: 1452 
Cannot add or update a child row: a foreign key constraint fails (`bitnami_dreamfactory`.`role_service_access`, CONSTRAINT

2020-12-15 12:23:58))

I have no foreign keys specified for the tables in the db I am connecting with.

I’ve reviewed a couple of the other issues, particularly, this one which says that it’s supposed to be fixed as of September, but I cannot seem to figure out why this is happening.

Thanks if anyone can help.

Hi
is there a way to get a records count when calling a stored procedure ? Like an include_count parameter.
As a workaround, the stores procedure returns 2 result sets : one with data, the second with a count of records. My problem is both result set are enclosed in array.
{
“components”: [
[
{
“count”: “1”
}
],
[
{
“ProductNumber”: “code”,
“description”: “description”
}
]
]
}

I would like to have an output like that :
{
“components”: [
{
“count”:1
},
{
“prmsProductNumber”:** “88787GR88” ,
“description”:** “Description of component” ,
}
]
]

Is it possible ?
Thank you
Gael

This is a stretch, but @Mark, or anyone else, if you’re out there. I’m having what might be the same problem. Running PostgreSQL and have a table with no foreign keys at all but getting the message. I made an issue at "Cannot add or update child row" error when creating role

Hi all,

I am attempting to use python scripts as a service and as a pre-post process script but in either case but I am getting the below response along with my initial request.

“error”: {
“code”: 500,
“context”: null,
“message”: “Executed command returned with error code: 1”,
“status_code”: 500
}

This error occurs with any type of python code (including the sample code). Nodejs and PHP are working correctly.

print(‘Hello Python’)

return(‘Hello Python’)

raise ValueError(‘Hello Python’);

I have set the confirmed both Python3 (3.5) and Python are set paths.

I have added the below to my .env file and /etc/environment

DF_PYTHON3_PATH=/usr/bin/python3

I have confirmed that this is the actual location of the python executables.

I’ve installed munch using pip3 (confirmed installation in python3.5/site-packages)

I’ve restarted apache2 and

php artisan cache:clear
php/php artisan config:clear

Python installations:

image1075×285 94.6 KB

I’ve configured the service, app, and roles for my endpoint. I can successfully run API calls on /schema, /function, /table - basically all the single nodes that don’t have a table name.

When I do add a table name (e.g., /table/myTableName) I receive a 500 error:

{
  "error": {
    "code": 500,
    "context": null,
    "message": "Failed to retrieve records from 'getresidents'.\nSQLSTATE[42703]: Undefined column: 7 ERROR:  column d.adsrc does not exist\nLINE 1: ...ER(format_type(a.atttypid, a.atttypmod)) AS type, d.adsrc, a...\n                                                             ^ (SQL: SELECT a.attname, LOWER(format_type(a.atttypid, a.atttypmod)) AS type, d.adsrc, a.attnotnull, a.atthasdef,\n\tpg_catalog.col_description(a.attrelid, a.attnum) AS comment\nFROM pg_attribute a LEFT JOIN pg_attrdef d ON a.attrelid = d.adrelid AND a.attnum = d.adnum\nWHERE a.attnum > 0 AND NOT a.attisdropped\n\tAND a.attrelid = (SELECT oid FROM pg_catalog.pg_class WHERE relname=:table\n\t\tAND relnamespace = (SELECT oid FROM pg_catalog.pg_namespace WHERE nspname = :schema))\nORDER BY a.attnum)",
    "status_code": 500
  }
}

This even occurs when running from the API Docs inside of the DreamFactory app.

Are there any specific permissions I need to have on the user? I’m even trying with the default postgres user and am getting this error.

I could really use help from anyone who can offer assistance. Thanks.
