Data sources or data items not being displayed

In certain circumstances, data sources or data items are not displayed in the solution.

Symptoms

Data items are not displayed on the maps, or in the list.

Diagnosing the problem

On the data server, check the IOCDATA database and confirm that data records have been imported into the target data table. The table name format is TARGET_TABLE_yourDataSourceName.

To receive alerts that inform you when data import fails, configure the alert settings in your user profile. Click Edit Profile > Alert Settings > System Messages > Data Import. System dashboard alerts are enabled by default, but you must configure email and SMS alerts.

For detailed debugging information, follow the instructions that are given in Enabling traces and viewing log files to enable the following traces:

com.ibm.ioc.logger.DataReceiverLogger
com.ibm.ioc.logger.DataReceiverPersistenceLogger
com.ibm.ioc.logger.DataReceiverRuntimeLogger

Then, re-create the data source and review the following log file:

/opt/IBM/WebSphere/wlp/usr/servers/iocsvr1/logs/trace.log
