Tip1 : Java With OTD and Big File Handling For JCAF

Somebody asks me why you like JCAPS. One of things is Java and OTD.

If you know Java, you can easily include any JCAPS OTD into your java program. If I have really complex interface, I always use this approach.

Big advantage with this approach is that ‘Your development cycle will be shortened with a couple of times faster’ and ultimately it saves a lot of money for your IT.

I will reuse jcdFileMappingExample collaboration in ‘Example2. Batch Transaction Type article.’ If you don’t have it, please refer to the following URL to download files.

Java program will be tested with small and big file.
Big file will be generated with batch script called GenerateSampleFile.bat under $JCAPS_COMMON_ROOT\utilities directory.
Total Elpased time with FileMappingExample.java is 366531 milliseconds (6 minutes 6 seconds 531 milliseconds).

	Input File	Output File
One Record Size	176 Bytes	205 Bytes
Total File Size	1,780,000,000 Bytes (1.66 GB)	2,070,000,000 Bytes (1.93 GB)
