![]() APAR status Closed as program error. Error description Customer is running on OS/390 R10 and changed the ARCHLVL in sys1.parmlib to 2 indicating that they wanted 64 bit addressing opposed to 31 bit addressing. The HTTP plugin abends with an abend0c4 in _dofmto when changing to 64 bit mode. In 32 bit mode it does not abend but the trace entries are formatted incorrectly in the HTTP Plugin code. You can determine if you are in 64bit mode by finding the 64 bit PSW. NOTE: psw starts with BIT zero. 24-BIT addressing: Bits 31 and 32 are zero 31-BIT addressing: Bit 31 is zero and BIT 32 is one. 64-BIT addressing: Bits 31 and 32 are one.

When z/OS is configured for 31-bit mode, the Http Plugin will not abend; however, trace point data may contain formatting errors.Problem conclusion The problem occurs when the tracing code attempts to print the pthread id. The pthread id is 8 bytes in length on z/OS and the tracing code was originally written to handle a 4-byte pthread id. The tracing code was changed to correctly print an 8-byte pthread id.
