Problem summary

  • APAR NUMBER:  PJ40904
    PRODUCT:  z/TPF
    FUNCTIONAL AREA:  SYSTEM ERROR AND RECOVERY
    SHIPPED IN PUT:  10
    
    ABSTRACT:
    Due to PJ34217, when the MAXSNAP threshhold is reached, CPSU is
    not notified and the OMD code may continue to
    issue WTOPC's
    
    PACKAGE CONTENTS:
    Source Segments:
    (C) base/rt/cpsi.asm
    (C) base/rt/cpsu.asm

    Configuration Independent Binaries:

    Support Files:

    OTHER BINARIES TO BUILD: YES
    (C) <sys>/load/CPSI.so
    (C) <sys>/load/CPSU.so
    (C) <sys>/obj/cpsi.o
    (C) <sys>/obj/cpsu.o
    
    COMMENTS:
    PJ34217 added code to suppress WTOPC's issued by SNAPC
    processing when a threshhold is reached. However if CPSU has no
    way of knowing if this threshhold has been reached. In addition
    code that handled lowcore conditions was accidently dropped for
    z/TPF.
    

Problem conclusion

  • SOLUTION:
    Comments in CPSU has been added to indicate that EBXSW01 should
    be tested for CPSIMAX to handle the case when WTOPCs have been
    suppress in CPSI. Code in CPSI has been reinstated to issue
    INSUFFICIENT STORAGE, DATA OMITTED FROM DISPLAY, when a low
    core condition is detected.
    
    COREQS: NO
    None.
    
    MIGRATION CONSIDERATIONS: YES
    User exit changes:
    CPSU has been changed to indicate the usage of EBXSW01 for
    SNAPC dumps
