Upgrading from or Reinstalling Versions That Were Installed after the July 2015 Release of SAS 9.4

Upgrading from or Reinstalling Versions That Were Installed before the July 2015 Release of SAS 9.4

To upgrade from or reinstall a previous version of the SAS Formats Library, the SAS Embedded Process, or both, follow these steps:

Check the current installed version of the SAS formats library.
How you do this depends on the version of the SAS formats library.
- If a SAS 9.2 version of the formats library is currently installed, run this command:
  
  psh "rpm -q -a" | grep jazxfbrs
  
  If a previous version is installed, a result similar to this is displayed. The version number might be different.
  jazxfbrs-9.2-1.9
- If a SAS 9.3 or SAS 9.4 version of the formats library is currently installed, run this command:
  
  psh "rpm -q -a" | grep acc
  
  If a previous version is installed, a result similar to this is displayed. The version number might be different.
  accelterafmt-3.1-1.x86_64
If the library is not installed on the Teradata nodes, no output is displayed. You can continue with the installation steps in Installing the SAS Formats Library and the SAS Embedded Process.
Run this command to check the current installed version of the SAS Embedded Process.
```
psh "rpm -qa | grep tkindbsrv"
```
If a previous version is installed, a result similar to this is displayed. The version number might be different.
```
tkindbsrv-9.42_M1-2.x86_64
```
If the SAS Embedded Process is not installed on the Teradata nodes, no output is displayed. You can continue with the installation steps in Installing the SAS Formats Library and the SAS Embedded Process.
If a version of the SAS formats library, the SAS Embedded Process, or both is being installed that has a name that is different from the library that was previously installed, then follow these steps. An example would be one of these:
- accelterafmt-3.1-1 replacing jazxfbrs-9.2-1.6
- sepcoretera-4.3000-1 replacing tkindbsrv-9.42_M1-2
1. If you are upgrading from or reinstalling the SAS Formats Library, shut down the Teradata database.
  
  tpareset -y -x shutdown_comment
  
  This step is required because an older version of the SAS formats library might be loaded in a currently running SAS query.
  
  Note: If you are upgrading or reinstalling only the SAS Embedded Process (tkindbsrv.rpm file), you do not need to shut down the database. You do need to shut down the SAS Embedded Process. For more information about how to shut down the SAS Embedded Process, see Controlling the SAS Embedded Process.
2. Confirm that the database is shut down.
  
  pdestate -a
  
  DOWN/HARDSTOP is displayed if the database is shut down.
3. If the SAS Data Quality Accelerator for Teradata is installed, you must uninstall it before you uninstall the SAS Embedded Process. For more information, see Upgrading from or Re-Installing a Previous Version of the SAS Data Quality Accelerator.
4. Remove the old version of the in-database deployment package before you install the updated version.
  
  To remove the packages from all nodes concurrently, run this command:
  
  psh "rpm -e package-name"
  
  package-name is either jazxfbrs.9.version, accelterafmt-version, or tkindbsrv-version.
  
  For example, to remove jazxfbrs, run the command psh "rpm -e jazxfbrs-9.2–1.6".
  
  To remove the package from each node, run this command on each node:
  
  rpm -e package-name
  
  package-name is either jazxfbrs.9.version, accelterafmt-version, or tkindbsrv-version.
(Optional) To confirm removal of the package before installing the new package, run this command:
```
psh "rpm -q package-name"
```
package-name is either jazxfbrs.9.version, accelterafmt-version, or tkindbsrv-version.

The SAS Formats Library or the SAS Embedded Process should not appear on any node.
Continue with the installation steps in Installing the SAS Formats Library and the SAS Embedded Process.
