(ZOS) Hexadecimal conversion of Java error codes

Occasionally, Java will take an WebSphere Application Server for z/OS error code (C9C2xxxx in hexadecimal) and convert it to a very large negative number. If we get a very large negative number, try converting it back to hexadecimal to find the correct code.

To convert the error codes back to hexadecimal we must add 2³² to the negative number and convert it into hexadecimal. This can be done using the OMVS command.

 bc

Example: Suppose we get the error code "910022649":

1. Under OMVS, type the command:

   bc
   

2. Then type:

   obase=16
   2^32 - 910022649
   quit
   

   The bc program displays C9C22807, which is the hex value that we should look up.
