Peaceful Coexistence: SAS® 9.2 and SAS 9.1.3

It is possible to run SAS 9.2 and SAS 9.1.3 simultaneously on the same computer. This topic lists all known issues, to help you avoid any conflicts. If you want to run a SAS 9 release on the same computer as SAS 8.2, see Peaceful Coexistence: SAS®9 and SAS 8.2.

Known Issues for Coexistence

• Data sets and other SAS files: SAS strives wherever possible to support cross-release compatibility.
  • Use the interactive Compatibility Calculator (support.sas.com/rnd/migration/planning/files/calculator/) to determine whether you can use your SAS 9.1.3 files in SAS 9.2 without migrating them to SAS 9.2 format.
  • If you use certain SAS 9.2 file features (support.sas.com/rnd/migration/planning/files/forward.html), then those SAS 9.2 files are incompatible with SAS 9.1.3. The features are optional.
  • If you upgrade to 64-bit SAS, it is recommended to not store 64-bit SAS files in the same library as 32-bit SAS files. The level of access supported between the 32-bit and 64-bit versions of files is different. Keeping your 64-bit SAS 9 files in a separate location will keep data access functionality consistent within the library.
  • If you make a copy of a data set to test the new release of SAS and the data set is live (that is, continually updated), then you must either update the two data sets concurrently or designate one data set to be frozen and later discarded.
  
  
• Syntax and New Features: Some syntax and features in your SAS 9.1.3 code, stored processes, and custom applications might behave differently in SAS 9.2. If you update your code for SAS 9.2, you might not be able to run it in SAS 9.1.3. See Special Considerations for Customers Upgrading to SAS® 9.2 (support.sas.com/92administration).
  
  
• Installation and configuration:
  • If you are installing both SAS 9.1.3 and SAS 9.2, install SAS 9.1.3 first. Otherwise, you might run into problems with the shared files directory.
  • Make sure SAS 9.2 doesn't use the same TCP/IP port numbers as SAS 9.1.3.
  • Install SAS 9.1.3 and SAS 9.2 in separate locations on the machine.
  • You can add multiple SAS 9.2 orders to a single SAS Software Depot, but do not add a SAS 9.2 order to a SAS 9.1.3 Software Depot, or the SAS 9.1.3 content might be overwritten or corrupted.
  • It is recommended that you use the SAS configuration file (sasv9.cfg) to separate the locations of SASWORK.
  • If you are migrating a metadata-based deployment from SAS 9.1.3 to SAS 9.2, use the same installer account and administrative accounts for both deployments to avoid permission issues.
  
  
• Operating environment:
  • Some SAS 9.1.3 operating environments (support.sas.com/rnd/migration/planning/platform/sas9platforms.html) are no longer supported in SAS 9.2.
  • Updates made to an operating environment for SAS 9.2 system requirements (support.sas.com/documentation/installcenter/) might conflict with SAS 9.1.3, although this has not been reported.
  • Running two versions of SAS on a machine might require additional disk space or CPU time.
  
  
• Invoking SAS:
  • You can run SAS 9.1.3 and SAS 9.2 simultaneously in batch.
  • You can run SAS 9.1.3 and SAS 9.2 simultaneously in interactive sessions from the SAS windowing environment (aka Display Manager). However, on Windows, due to the use of the Windows registry and services, you are advised to not run SAS 9.1.3 and SAS 9.2 metadata-based SAS Business Intelligence, Data Integration, and Solutions concurrently (at the same time) on the same Windows computer. You can avoid problems by using scripts to switch between the two instances.
  • The SAS command can be set to one or the other release of SAS by the operating environment. This setting might be done by search paths, registry settings, or operating environment conventions. Take care when invoking SAS to ensure that you are getting the release of SAS that you want.
  • SAS environment variables can differ between SAS 9.1.3 and SAS 9.2. Failure to set the environment can result in errors, including incorrect user-ID authentication with the SAS 9.2 Metadata Server. A recommended solution is to write a script that sets the environment variables when SAS is invoked. Here is a sample environment-setting program for UNIX, provided by a customer:

    PATH=/usr/local/bin:/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:$HOME:.
    export SASROOT=/usr/local/sas/sas913
    export PATH=$PATH:/usr/local/sas:$SASROOT:$HOME/bin
