Cisco recommends that you have knowledge of Cisco Conference Connection (CCC).

Components Used

The information in this document is based on Cisco Conference Connection version 1.2.2.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Users cannot use Cisco Conference Connection (CCC) in order to schedule conferences (23-24 hour duration) that repeat for over 14 days. When the user schedules conferences, the webpage hangs and times out after one (1) hour. Users must close HTTP sessions and open another browser window. At times, the system must be restarted in order to use CCC.

CCC hangs with this database error (which appears in the application event log):

Event Type: Error
Event Source: MSSQLServer
Event Category: (2)
Event ID: 17052
Date: 3/2/2004
Time: 11:17:45 AM
User: N/A
Computer: USCITVC10
The description for Event ID ( 17052 ) in Source ( MSSQLServer ) 
   cannot be found. The local computer may not have the necessary 
   registry information or message DLL files to display messages 
   from a remote computer. The following information is part of 
   the event: Error: 1105, Severity: 17, State: 2 
Could not allocate space for object 'UsedResourceTable_1' in 
   database 'DCMS' because the 'PRIMARY' filegroup is full..


This issue is most likely triggered by a conference that crosses the Daylight Savings Time (DST) cutover. For example, if the DST cutover is at 2am on Sunday, Apr 4, 2004, any conference scheduled for that time exhibits this problem.

This issue is seen mostly with 24-hour conferences because they tend to schedule resources at night (usually the cutover time). Regular conferences and series conferences are usually scheduled in the daytime, when there is no cutover. This issue occurs when the Data Conference Meeting Server (DCMS) database is full.

In order to resolve this issue, complete these steps:

  1. Open a command prompt (DOS window).

  2. At the prompt, enter cd c:\MSSQL7\Binn osql -w 2000 -E -Q "sp_helpdb DCMS" -o out.txt.

  3. Check whether the primary file group shows a certain value for maxsize, and then set the database size growth to unlimited.

    In order to set the database size growth to unlimited, complete these steps:

    1. Use the Structured Query Language (SQL) Enterprise Manager (installed on the Cisco CallManager server) to connect to the CCC database.

      In order to start the Enterprise Manager, click Start, and then choose Programs > Microsoft SQL Server > Enterprise Manager.


    2. Right-click the SQL Server group, and choose New SQL Server Registration.


    3. Enter the name of the CCC server, click Add, and then click Next.

    4. Choose the authentication.

    5. Click Add to existing group, click Next, and then click Finish.

    6. After the connection is made, expand the database entry in the list. A database named DCMS appears.

    7. Right-click DCMS, and choose Properties.

      These two options appear under this property: unrestricted file growth and restrict file growth (with a numerical MB limit).

    8. In the Properties window, click the Data Files tab. At the bottom right, a property named Maximum File Size appears.

    9. Choose unrestricted file growth, and click OK.

Note:  You are not required to restart the CCC or SQL services after this procedure.
