APAR status

• Closed as program error.

Error description

• When configuring a DataBase connection and a host alias is used
  for the connection string, where the host alias is mapped to an
  IP address, DataPower performs a DNS lookup first instead of
  using the mapped IP address.
  

Local fix

• The work around until applying this fix is to use an IP address
  instead of the host alias for the DataBase connection string
  

Problem summary

• For DataPower users who use database connection and have defined
  database server IP in DataPower Host Alias configuration,
  DataPower doesn't use Host Alias data but always performs a DNS
  lookup.
  

Problem conclusion

• Fix is available in 7.1.0.18, 7.2.0.15, 7.5.0.9, 7.5.1.8,
  7.5.2.8 and 7.6.0.0

Temporary fix

• Use IP address instead of Host Alias configuration in DataPower.
