The system name can be viewed after installation using the Display Network Attributes (DSPNETA) command and changed using the Change Network Attributes (CHGNETA) command.  

The distributed relational database architecture (DRDA) automatically adds a local relational database (RDB) directory entry for the system that has the same as the system.  Typically, users change the system name but then neglect to change the *LOCAL RDB name.  It is recommended that the system name and the *LOCAL RDB name are the same but it is not required.  The *LOCAL RDB entry is required to do any connection to the local database.   The *LOCAL RDB entry also stores configuration data related to distributed data management (DDM) that should be maintained if the *LOCAL RDB entry is deleted and then recreated.

To rename the *LOCAL RDB name on the system, use the following steps:

  • Run DSPNETA/CHGNETA to verify the system name is set to the value to be used as the *LOCAL RDB name.
  • Run the Change DDM TCP/IP Attributes (CHGDDMTCPA) command and record the DDM configuration information.
  • Run the Remove RDB Directory Entry (RMVRDBDIRE) command to remove the *LOCAL RDB entry.  Reply G to message CPA3E01.  
  • Run the Start SQL Interactive Session (STRSQL) command to cause a new *LOCAL RDB entry to automatically be created.
  • Run

  • CHGDDMTCPA and reset the DDM configuration information recorded earlier.
