DFHSR0622 An attempt to overwrite the ECDSA has caused the abend which follows DFHSR0001 An abend (code 0C4/AKEA) has occurred at offset X'00002BD4' in program DFHEPC. . Following an abend in a remote program, an XPCTA exit program sets a RESUME address requesting that execution branch to that address in USER key.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHSR0622 An attempt to overwrite the * * ECDSA caused message DFHSR0001. * * An abend (code 0C4/AKEA) has occurred * * at offset X'00002BD4' in program * * DFHEPC. * **************************************************************** * RECOMMENDATION: * **************************************************************** User program PROG1 links to a remote program PROG2 which returns an abend. After DFHEPC creates the abend record it invokes exit XPCTA and XPCTA returns a retry address, and requests a switch to user key. Control returns back to DFHEPC. DFHEPC switches to user key, and then issues a CHANGE_MODE to ensure it is on the right TCB. This attempts to update CICS key storage while executing in user key, and so a protection exception (0C4) occurs. .

Problem conclusion
DFHEPC has been changed to do change mode before switch execution key to user key.
