Configuration Settings

The installer automatically searches the $SYBASE directory for DA installations. If there are multiple instances, the installer uses the valid instance directory that has been most recently modified. A "valid" instance directory must contain a readable configuration file that matches the directory instance name. For example:

$SYBASE/DA-15_5/server/instance/instance.cfg

or,

$SYBASE/DA-15_5/agent/instance/instance.cfg

The installer uses existing values for instance name, RMI port, TDS port, DTS port, DASD name, and DASD port. Each installation mode handles these existing values differently:

• GUI – existing configuration values are dimmed, and cannot be altered.
• Silent – silent installation parameters are ignored, and this warning message is added to the DA log file:

  Using the config variables from the existing installation.

• Console – does not prompt for DA server input values, and displays this message:

  Using the config values from the existing installation  
  (server instance instance)

The installer does not overwrite any existing password file in $SYBASE/DA-15_5/server/instance/security. Each installation mode handles this differently:

• GUI – you cannot change the password fields, which are dimmed.
• Silent – silent installation parameters are ignored, and this warning message is added to the DA log file depending on the password files found:

  Not using the given da_admin password, as an existing installation has been found.
  

  and/or,

  Not using the given DASD password, as an existing installation has been found.

• Console – does not prompt for DA server input values, and displays this message depending on the password files found:

  Using the password settings from the existing installation.
  

  and/or,

  Using the DASD password settings from the existing installation.
