Working with Larger Files
For large input files, you may need to increase the memory that is allocated. For example, if the general command to the run the utility is:
windchill wt.load.util.CSV2XML -input <file_name>.csv
Then, for large input files, you may need to allocate 512 MB of memory:
java -Xmx512m wt.load.util.CSV2XML -input <file_name>.csv
