Error description
When the age of a JVM gets to 49.7 days, there will be an abend0C9 on the CVD instruction because the number of milli- seconds exceeds the number that will fit into the 4 bytes reserved. The problem has been recreated by altering the SJTCB to make the JVM artifically older than it really is. After the CVB is done DFHSJIS then divides by 1000 to get the time inseconds. This divide should be done while thetime is still in a packed format, then the much smaller result converted to binary.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users * **************************************************************** * PROBLEM DESCRIPTION: An S0C9 abend in DFHSJIS occurs when * * the age of a JVM exceeds 49.7 days * **************************************************************** * RECOMMENDATION: * **************************************************************** A JVM has been running in CICS for at least 49.7 days. After this time a CEMT I JVM command is issued. DFHJSIS attempts to calculate the elapsed time. The current abstime is obtained and the start time of the JVM is subtracted from it. All this is done using packed arithmetic giving the age of the JVM in milliseconds. Then that packed number is converted to binary. If the packed number is bigger than 4,294,967,296 an S0C9 occurs. Keywords: ALLOCAGE AGE ABEND0C9 ABENDS0C9 0C9
Problem conclusion
DFHJSIS has been modified by calculating the number of seconds using packed arithmetic before converting to binary. This prevents the 0C9
