Note: Stop the embedded
process by using the instructions at Controlling the SAS Embedded Process before following these steps. Stopping
the SAS Embedded Process ensures that none of the accelerator files
are locked when dq_uninstall.sh attempts to remove them.
The accelerator provides the
dq_uninstall.sh shell script for removing the data quality stored
procedures from the Teradata database. The dq_uninstall.sh script
is located in the /opt/SAS/SASTKInDatabaseServer/9.4/TeradataonLinux/install/pgm directory
of the Teradata database server.
The dq_uninstall.sh
script requires modification before it can be run. The Teradata administrator
must edit the shell script to specify the site-specific Teradata server
name and DBC user logon credentials for the DBC_PASS=, DBC_SRVR=,
and DBC_USER= variables.
Here is the syntax for
executing dq_uninstall.sh:
./dq_uninstall.sh <-l log-path>
log-path
specifies an alternative
name and location for the dq_uninstall.sh log. When this parameter
is omitted, the script creates a file named dq_uninstall.log in the
current directory.
Running dq_uninstall.sh
disables the SAS Data Quality Accelerator for Teradata functionality
and removes the data quality stored procedures from the database.
The dq_uninstall.sh script does not remove the QKB or the SAS Embedded
Process from the Teradata nodes. Follow whatever procedure is appropriate
at your site for removing the QKB.
See Upgrading from or Reinstalling a Previous Version for information
about how to uninstall the SAS Embedded Process from the Teradata
database. The dq_grant.sh script also does not
remove permissions that were granted by dq_grant.sh. You need to remove
the permissions in accordance with the procedures used at your site.
