When navigating to the Reporting page under the Dbvisit Standby web based (GUI) interface it can happen that one or more of the graphs do not load correct, the below article explains how to resolve the issue and provides a workaround.

Problem Details

Open Flash Chart JSON Parse Error [Syntax Error] Error at character 0, line 1: ....

1. If None of the Graphs Are Loading

   If none of the graphs are displayed, it is possible that the flash plugin is not installed and enabled in the browser you are using. Please make sure you have installed the flash player and that it is enabled in your browser.

2. Graphs Are Partially Loading with Some Showing Error as Mentioned Above

   This option can happen on Windows based systems. The work-around is to stop Dbvserver service and edit the dbvserver.conf file located in $DBVISIT_BASE/dbvserver/conf by setting the following values:

   Under the [HTTP] and [HTTPS] sections modify the values of proc_minimum and proc_maximum to the value 1.

   [HTTP]
   ....
   ....
   proc_minimum = 1
   proc_maximum = 1
   ....
   ....

   [HTTPS]
   ....
   ....
   proc_minimum = 1
   proc_maximum = 1
   ....
   ....

   Example locations of the configuration file is: C:\Program Files\Dbvisit\Dbvserver\conf\dbvserver.conf or C:\Program Files (x86)\Dbvisit\Dbvserver\conf\dbvserver.conf

   Once the dbvserver.conf file is updated, restart the Dbvserver Windows service for the new settings to take effect.

1. Stop Dbvserver Service.
2. Edit dbvserver.conf and set proc_minimum and proc_maximum under the HTTP and HTTPS sections to the value 1.
3. Restart Dbvserver Service.

Note: Do not modify any of the other parameters except the proc_minimum and proc_maximum parameters.
