PH58089: /ERE BUILDQ CAUSED LOOP WHEN USING LOCAL VSO

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The /ERE BUILDQ command was looping when using local VSO.
  .
  If /ERE command proceeded with CHKNO=0001, DBFNRS10 cleared
  bitmap for DMHVs on VEREBITM, but it doesn't clear FREE DMHVs
  queue address on VEREFREQ. Since VEREFREQ was non-zero,
  GETDMHV routine in DBFERSY1 used this VEREFREQ address first
  to get DMHVs. It causes an unintended DMHV chain.
  During later /ERE process to free DMHVs, LOOP was occurred
  due to this unintended chain.
  

Local fix

• Use /ERE command without BUILDQ
