Hi, I am using HP-UX 11, I tried to run 20 instances of a java program which takes one command line argument (Integer , which is the Order No in our Database Oracle 8.1.6 ). In short,this java program takes a database connection and updates the corresponding order record. To run the 20 instances, I use a shell script execute_java, the content of the same given under $ cat execute_java nohup java OfflineReportFormatter 737 & nohup java OfflineReportFormatter 738 & nohup java OfflineReportFormatter 739 & nohup java OfflineReportFormatter 740 & nohup java OfflineReportFormatter 741 & nohup java OfflineReportFormatter 742 & nohup java OfflineReportFormatter 743 & nohup java OfflineReportFormatter 744 & nohup java OfflineReportFormatter 745 & nohup java OfflineReportFormatter 746 & nohup java OfflineReportFormatter 747 & nohup java OfflineReportFormatter 748 & nohup java OfflineReportFormatter 749 & nohup java OfflineReportFormatter 750 & nohup java OfflineReportFormatter 751 & nohup java OfflineReportFormatter 752 & nohup java OfflineReportFormatter 753 & nohup java OfflineReportFormatter 754 & nohup java OfflineReportFormatter 755 & nohup java OfflineReportFormatter 756 & $ The java program OfflineReportFormatter contains a System.out.println in the beginning of the program to sho which Order number it is currently processing. what happens is, when I run this shell (execute_java) some of them missing out in random fashion. If I try only with 12 or 13 processes all of them are getting picked up, once i try to run 14 or 20 as shown above it bombs. Please suggest a solution. Thanks Jaggi

Probably the maximum number of user threads is exceed, that's why some of those fails. It could also be some other resource like memory, file descriptors etc..
