Increasing the Java heap size is necessary if the TARA GUI monitors a job whose ARC output causes the GUI to exceed the default heap size of the Java Virtual Machine (JVM). A symptom of exceeding the default size is the GUI might freeze. If this happens, close the existing TARA GUI.
For Linux, modify the script for the TARA GUI to include this JAVA heap size extension:
-Xmx512m -jar "<path to Teradata taragui>\bin\taragui.jar"For Windows, modify the TARA GUI desktop icon to include the Java heap size extension:
C:\WINDOWS\system32\java.exe -Xmx512m -jar "<path to Teradata taragui>\bin\taragui.jar"This increases the maximum heap size from 128 MB to 512 MB.
