During an upgrade or reinstallation, the installer uses the configuration settings
from the previous installation.
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.
