Troubleshooting Maps

Maps provide a graphical representation of the relationships between Axon objects across different facets.
You might encounter the following issues with maps:
Perform the following tasks to fix notification issues:

Verify that the Graph Database Service is Running

To verify that the Graph Database service is running, go to the <INSTALLATION_DIR>/axonhome/third-party-app/scripts directory in the Linux environment, and run the following command:
sh orientdb status
If the service is shut down, go to the <INSTALLATION_DIR>/bin directory, and run the following command to restart the Axon services:
sh startup.sh
If the Axon maps are displayed incorrectly after you restart the Graph Database service, perform the following steps in the Linux environment to reindex the database:
  1. 1. Run the following command to define the Axon environment variable so that the Linux system can access the Axon resources at the correct location:
    2. source <INSTALLATION_DIR>/scripts/exportEnv.sh
  2. 2. Go to the <INSTALLATION_DIR>/scripts directory, and run the following script to reindex the database:
    3. sh reIndex.sh

Verify that the OdbConsumer Service is Running

To verify that the OdbConsumer service is running, go to the <INSTALLATION_DIR>/axonhome/third-party-app/scripts directory in the Linux environment, and run the following command:
sh OdbConsumer status
If the service is shut down, go to the <INSTALLATION_DIR>/bin directory, and run the following command to restart the Axon services:
sh startup.sh

Verify that Data Set and Attribute Reference Numbers Have Prefixes

To verify that the data sets and attributes have prefixes for the reference numbers, perform the following steps:
  1. 1. Log in to Axon with the SuperAdmin profile.
  2. 2. From the Axon toolbar, click the Admin Panel menu item under your user name.
  3. 3. In the menu on the left, under the Customize & Configure category, click System Settings.
  4. 4. In the Group list, select Reference Number Settings.
  5. 5. In the Facets Reference Number window, make sure that the CatalogueItem and CatItemComponent parameters have a prefix value. The CatalogueItem parameter represents data set prefix, and the CatItemComponent parameter represents attribute prefix.
    6. "CatalogueItem": {
    "RefNumber": "DS-"
    },
    "CatItemComponent": {
    "RefNumber": "AT-"
    }
  6. 6. If the CatalogueItem and CatItemComponent parameters do not have a prefix value, click the Edit icon.
  7. 7. In the Facets Reference Number window, enter a prefix value for the CatalogueItem and CatItemComponent parameters.
    8. "CatalogueItem": {
    "RefNumber": "<Data_Set_prefix>"
    },
    "CatItemComponent": {
    "RefNumber": "<attribute_prefix>"
    }
  8. 8. In the Facets Reference Number window, click Save to save your changes.
  9. 9. In the System Settings page, click Save to save your settings.
  10. 10. In the Linux environment, run the following command to clear the Axon cache and restart the necessary services:
    11. sh <INSTALLATION_DIR>/axonhome/third-party-app/scripts/paramsync
  11. When you run the paramsync script, Axon restarts the HTTPD, Memcached, and email notification services.
Note: When you clear the cache and restart the Axon services, the Axon web interface might be disrupted for some users that are logged into Axon. Informatica recommends that you update the cache after you save your changes in all the System Settings pages. Additionally, perform this action during a maintenance period when very few users are using Axon.
