Call failed on the server

Symptom:

When I try to connect to the Mart server, I get the following error:

Solution:

The probable reasons for this error could be one of the following reasons:

• The server name is not correct.

Application Internal Error

Symptom:

When I try to connect to the database, I get the following error:

Application Internal Error

Solution

You get this error when the MartServer application is unable to connect to the required database. The following reasons are probable for this error:

• The database details that are provided in the Configure MartServer Details dialog are incorrect.
• The username and the password for the database are incorrect.
• The database is not present.
• The port number for the database is incorrect.
• The network is down.

Ensure that you enter the correct details of your database in the Mart Server tab of the CA ERwin Mart Configuration dialog.

Initialize page is not loading in Internet Explorer

Symptom:

To enable Active Scripting, follow these steps:

1. In Internet Explorer, click Tools, Internet Options.
2. In the Security tab, click the Custom Level button.

   The Security Settings – Local Intranet Zone window opens.

3. From the list of options, locate Scripting, Active Scripting, and select Enable. Click OK.
4. Restart Internet Explorer and enter the URL to initialize Mart.

   The Mart Initialize page opens.

Test connection failed

Symptom:

When I use the Mart Upgrade utility on a 64-bit computer and upgrade a r7.3 through r8.2.7 Mart to r9.0 or r9.1 Mart, I get the following message:

Test connection failed

Solution:

CA ERwin DM is a 32-bit application. When you try to upgrade to r9.0 or r9.1 Mart on a 64-bit computer, the COM components do not work.

Follow these steps:

1. Paste the code included at the bottom of this topic to a Notepad file and name it as 64_Bit_Upgrade.reg. Note down the folder where you have created this file.
2. After installing CA ERwin DM version 9.0 or 9.1, right-click 64_Bit_Upgrade.reg and select Merge.
3. From the Windows Start menu, go to Run and type the following commands to re-register the EAL components:

   regsvr32.exe  "<Install Dir>\CA\ERwin Data Modeler r9.0\EAL.dll" 
   

   regsvr32.exe  "<Install Dir>\CA\ERwin Data Modeler r9.0\ Upgrade\R8_Binaries\EAL.dll".
   

4. Right-click 64_Bit_Upgrade.reg and select Merge again.

   You can now upgrade to version 9.0 or 9.1 Mart on a 64-bit computer.

64_Bit_Upgrade.reg

Copy the following code and paste it to a new Notepad file:

Internet Explorer Redirects to a Different Link

Symptom:

Suppose that I install CA ERwin Mart Server on a fresh machine. If I enable the SSL option and I invoke CA ERwin Mart Administrator, Internet Explorer redirects the page to res://ieframe.dll//.

Solution:

Internet Explorer versions 8 through 10 have a security enhancement that blocks the following types of sites:

• Sites that have self-signed certificates
• Sites that have self-signed certificates where the certificate does not match the URL

Follow any of these steps:

• Install the certificate in the Trusted Root Certification Authorities store.
• Add the site to trusted sites.
• Set the Internet Explorer Security level to Medium Low.
