Problem summary
**************************************************************** * USERS AFFECTED: All CICS Users. * **************************************************************** * PROBLEM DESCRIPTION: Message DFHSM0133 (short on storage) * * is incorrectly issued by CICS after * * a getmain for 1 gigabyte. * **************************************************************** * RECOMMENDATION: * **************************************************************** A GETMAIN for 1 gigabyte of 31-bit storage in the CICS EDSA may cause CICS to incorrectly report a short-on-storage (SOS) condition. DFHSMPP calculates how many free bytes will remain in the EDSA if the getmain request is satisfied, but the result is stored in signed fullword field. The large value for the getmain results in the high order bit being set so that the result incorrectly becomes negative. When this value is compared against the cushion size for the EDSA it is lower and so CICS incorrectly reports an SOS condition for below-the-bar storage. Additional keyword: msgDFHSM0133 DFHSM0131 msgDFHSM0131 DFHSM0606 msgDFHSM0606
Problem conclusion
DFHSMPP has been altered to increase the size of the field used when calculating the number of free bytes so that it will not become negative when getmaining large amount of storage.
