Log in, users and groups

Table 2: Known issues with log in, users and groups

Known Issue Issue ID

On adding users to Intelligence Central from Active Directory and two of those users have the same username (different domain) then only one user will be added to Intelligence Central.

Each username on Toad Intelligence Central must be unique.


In some instances, Intelligence Central may not release some connections after the user disconnects. A user may encounter a "number of connections exceeded" message when attempting to connect after the maximum number of connections has been reached. This release of Toad Intelligence Central now allows up to 1024 connections (sessions).

Workaround: If a new connection cannot be opened because the maximum number of connections has been reached, restart the Toad Intelligence Central server.


If the machine hosting Toad Intelligence Central is not part of a domain then it will not be able to validate an Active Directory user log in from the Web Server, the Admin Console, or a client application (Toad Data Point). 3253
Web Server: When the Administrator resets the password for an Intelligence Central user or enables an Intelligence Central user from a computer that does not have an email client installed, there may be problems if the Administrator chooses to email the new password to the user. 4087
Web Server: You may experience a failure to log in to a web browser from Windows Server 2008 (64 bit) using Internet Explorer.

Workaround: Disable Internet Explorer Enhanced Security Configuration. See also Microsoft Technet:

  1. From the Windows Start menu click All Programs | Administrative Tools | Server Manager to open the Server Manager.
  2. Under Security Information, disable Configure IE ESC.

Web Server: Failure to connect to a web browser from Windows Server 2012 using Internet Explorer.

Workaround: From Internet Explorer click Tools | Internet Options | Security. Add the Web Server as a trusted site to the Internet Explorer Enhanced Security Configuration.


Connections from Toad Data Point to Toad Intelligence Central: Failure to connect to Toad Intelligence Central via a proxy server.

Workaround: Ensure your Proxy Server is able to connect to the remote host where the Toad Intelligence Central server is running and supports HTTPS traffic.


Toad Data Point 3.8: The Administrator role functionality is not recognized when editing and deleting Intelligence Central groups. An Intelligence Central group can be deleted by the owner of the group and root Administrator only.

Workaround: Users with the Administrator role can use the Web interface (Web server) to edit and delete Intelligence Central groups.

Data connectivity license: Objects from data sources

Table 4: known issues with objects from data sources

Known Issue Issue ID

Snapshots can be stuck in a permanent 'Running' state following an unexpected event, for example if Toad Intelligence Central stops unexpectedly. While the snapshot is permanently 'Running' the snapshot data cannot be refreshed.

Workaround: Restart the Toad Intelligence Central server. Instructions are provided in the Toad Intelligence Central Deployment Guide.



Table 5: Known issues - data source specific

Known Issue Issue ID
Generic ODBC: Cannot map to a Generic ODBC data source if the DSN contains spaces. 2965

Google Analytics: Mapping tables with start_date and end_date on a where clause have the following requirements:

  1. Acceptable values for start_date and end_date are:
    • today
    • yesterday
    • <N> daysAgo (where <N> represents the number of days)
    • YYYY-MM-DD (year/month/day date format)
  2. If there is a subquery then the start_date clause must in the innermost subquery.

Note that if optimizations are skipped then the start_date and end_date won't take affect.


Oracle BI Enterprise Systems: Unknown error occurred while processing the query. The Oracle BI Enterprise Systems data source has timed out on the query.

Workaround: Rewrite your query to return smaller datasets then join the results. For example you may want to query data one quarter at a time rather than for a whole year.


Apache Cassandra™: Mapping tables using the CQL (Cassandra Query Language) protocol some columns are not accessible.

Background: There are issues around declaring a single column 'statically' in the CREATE COLUMN FAMILY statement, then adding other columns 'dynamically', as discussed in the Mixing static and dynamic section of “the upgrade to CQL3 will be less straightforward than in the case of pure static or pure dynamic column families. Namely, CQL3 still consider the column family static because the definition of [ADDRESS is static]. But since the [other] columns themselves are not declared … you will not be able to access them for CQL3”


Apache Cassandra: Attempting to connect from Windows machine with IPv6 enabled (which includes, for instance, Windows 7 by default) to an Apache Cassandra server on the same machine using the host name "localhost" fails with the message "Could not connect client socket: Already open".

Workaround: Connect with the equivalent IPv4 address instead, for example "".


Apache Cassandra: Databases must be configured to use an Order Preserving Partitioner in order to support range queries on the identifier column. 11518
Apache Cassandra: Mapping tables with dynamic super columns whose names contain dynamic column names is not supported. 11506

Apache Cassandra: Toad Intelligence Central does not support column-oriented tables. Toad Intelligence Central is only able to discover tables in the key-value model.

MongoDB: For a MongoDB 3.0 (or later) connection, the user must have Read/Write privileges in the MongoDB database in order to view sub-tables (MongoDB embedded documents). 5520

MySQL: Character data not encoded in UTF-8 is truncated at the first non-ASCII character.

For example the word Protegé from a column encoded in latin1 is truncated to Proteg.

Toad Data Point 4.0 - SAP ASE: In an SAP ASE time type column, fractional seconds might be unexpectedly trimmed from data. This issue was encountered in a data object (snapshot) published from an SAP ASE data source using Toad Data Point 4.0 (or earlier).
