Update CICS trace to record the CPU type (CP or zIIP) on each trace entry.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All CICS users * **************************************************************** * PROBLEM DESCRIPTION: CICS trace does not indicate whether * * a general CP or a zIIP processor is * * being used. * **************************************************************** When a CICS Java task runs, it is possible to see how much CPU time is spent on a general CP or on a zIIP. It is also possible to identify how much zIIP-eligible work actually ran on a zIIP. It is not currently possible to identify which sections of CICS code ran on the zIIP and which were on a general CP. This makes it difficult to locate and correct any code that was managing the zIIP state inefficiently.
Problem conclusion
The CICS trace has been enhanced to capture the processor type on each trace entry. The trace formatter has been enhanced to display the type as part of the TCB information in the FULL trace as follows; TCB-C/T8001/00888800 or TCB-Z/T8001/00888800 The CICS Transaction Server for z/OS Version 5 Release 1 Data Areas manual (GC34-2849-00) will be updated as follows; TREN - Trace Entry, table 625 will have the row for offset 17 replaced with (17) UNSIGNED 1 TREN_CPU_TYPE CPU (CP, zAAP, zIIP) The same change will be made for the CICS Transaction Server 5.2 Data Areas manual (GC34-7271-00) table 633 and CICS Transaction Server 5.3 Data Areas manual (GC34-7406-00) table 633.
