Troubleshooting
Problem
When trying to open a chart in the i2 EIA Investigate web tool, you receive an error:
Operation failed
The application failed to open your network chart.
Retry the operation, or contact your system administrator.
Retrying the operation returns the same error, over and over.
Cause
This error was reported by a customer after they had accidentally run out of disk space.
The i2 Analyze "data" directory was on the drive which ran out of disk space (C:\IBM\i2Analyze\Data on Windows, /opt/IBM/i2Analyze/data on Linux).
This resulted in the i2 Chart cache on disk becoming corrupted.
Resolving The Problem
1. To recover, stop Liberty:
setup -t stopLiberty
2. In the topology.xml file under the i2EIA\toolkit\configuration directory, there is a section that defines file stores.
Look at the entry of type chart-store. For example, on my test server it shows:
<file-store location="C:/IBM/i2Analyze/data/chart/main" id="chart-store" type="chart-store"/>
3. Navigate to the folder, as described in their topology file where you should see 3 files:
charts.db
charts.db.p
charts.db.t
charts.db.p
charts.db.t
Delete those 3 files.
There may also be an analyze.lock file and if so that can also be deleted.
4: Restart Liberty:
setup -t startLiberty
If you have created web Charts, there may be sub-folders under "main" eg "C:\IBM\i2Analyze\data\chart\main\2020". You should initially leave these directories alone, as they hold the saved web Charts. If you still get problems, or do not mind losing the web chart sessions, you can stop Liberty and delete the whole contents of the file-store location folder mentioned above, including the year based ones containing the web chart sessions.
After you restart Liberty, you should be able to run the i2 EIA Investigate web client normally.
