In response to a D U,,ALLOC command, msgIEE106I is issued indicating a jobname of *UNKNOWN for certain DASD units. It is also not possible to Vary the unit(s) offline (unable to vary). This problem was traced to an OEM product changing the UCB in a job's TIOT without incrementing the new UCB's UCBUSER (Number of Current Users use-count) field. When the new UCB was subsequently de-allocated, MVS Allocation code decremented UCBUSER, causing it to become negative. Since UCBUSER was then not zero, the device appeared to be allocated even though there was no address space known to be allocated to it. As a result, UCBALOC was never turned off and the device could not be varied OFFLINE.
See Scratch Pad for OEM information. Please help me to solve the problem. from where i can find scratch pad for OEM? in OS configuration or hardware?!How can I turned off UCBALOC ? For your information we changed the number of aliases in IODF and just activate it without IPL or power on reset the machine.
