Denodo Model Bridge Enterprise Architect (Sparx) support

2023-01-27T07:26:58Z

Hello, According to Denodo Model Bridge manual (https://community.denodo.com/docs/html/document/denodoconnects/8.0/en/Denodo%20Model%20Bridge%20-%20User%20Manual), a few data modelling tools such as ER Studio, ERWin files are supported to import data model in Denodo (VDP model). Is there any plan to support additional data modelling tool such as SparxSystems Enterprise Architect ? In the meantime, is there a generic file format that could be used between Sparx EA and Denodo ? Thanks

Transient "Insufficient privileges" error when connecting through ODBC using an AD user

2023-01-25T18:16:23Z

Hi, We have an AD group (imported as Role in Denodo) with Admin privileges over a VDB. When we try to connect to that Denodo VDB through ODBC using an AD account associated to that group, sometimes we get a successful connection and some other times we get "Insufficient privileges to connect to the database {Db Name}". We tested using a DSN and without a DSN and we were able to reproduce the issue in both cases. Also we tested from 2 different Windows VMs having the Denodo ODBC driver installed (v9.03.06) and at some point we got a successful connection from one VM and error from the other one, using the exact same credentials. In both cases, when testing at different times we get successful connections, so we can discard any credentials issue. So far we did not have any issues with that AD account when accessing using the VDP Admin tool. Any ideas of what could cause this behavior? Thanks.

Adding prefix to a register subfields

2023-01-25T18:03:21Z

Hello, I want to add a prefix to all register subfields. In my case I have a register of registers. For each subfield of the register i want to add a specific prefix depending on the position of the register in my schema. For example, I have a register Json, in which there is another register "form" and a second register "candidate". I want to add the same prefix "level0" to both "form" and "candidate" at once. In my case I have more than 50 sub register and it's hard to rename one by one. Thank you,

Two Solution Managers

2023-01-24T19:43:27Z

Hi Denodo wizards, Can we have two solution managers , one for Pre-prod Denodo and one for Prod Denodo? Also, currently we have just one solution manager for pre-prod and prod. We want to create a POC solution manager for testing something, so can we use the same license file as the original solution manager? Your responses are appreciated. Thanks.

Return all the privileges for the Roles created in the Denodo VDP.

2023-01-24T16:37:48Z

Hi, I am trying to create a report on the privileges that each role has witin Denodo so that I can tie this into a report on Active Directory user and groups I already have. The idea is to return every role and the privileges returned byt the desc role command. I have followed the article here but it does not return the Privleges column so is does not provide the information required. https://community.denodo.com/answers/question/details?questionId=9060g000000XeRhAAK&title=List+of+Roles+and+complete+hierarchy I also tried the offered solution here using Catalog Permisions() but this does not return all the roles only the roles I have. https://community.denodo.com/answers/question/details?questionId=9060g0000004FTKAA2&title=Create+a+view+using+%27List+Roles%3B%27+Denodo+Virtual+DataPort+datasource How do I return all the roles and privileges for all roles?

List of All DataSource

2023-01-24T10:59:48Z

Hi team, I am using Denodo 8.0 version where I want to see details of all the DataSource created in my server.For which I tried this option 'DESC DATASOURCE ?, but in this I have to give one datasource name at one time and then it gives me details about that. Do we have any other option like table or procedure which can give me details of all DataSources like Name of DataSource, Coneection URI , UserName , Type in one go for all the datasources created. Also , I have checked that we have DataSourceManagementInfo MBean which contains all details about the datasource.Can you tell me how to use this Mbean. Where I can find this or execute this so that I can get the details.
