POST-INSTALLATION INSTRUCTIONS

If your SAS Web Server is configured for TLS, you will need to install the latest Java 7 Update. Please visit the Updates for Java 7 download page for the latest available updates.

IMPORTANT NOTES Regarding hot fix updates:

1. This hot fix will create a backup configuration directory under <SASConfig>/LevX/Web/WebServerBackup. If you manually changed any configuration settings for SAS Web Server, you must manually merge these settings back into the new web server configuration.

2. This hot fix updates the Apache httpd server from version 2.2 to version 2.4. Any manually configured changes for SAS Web Server related to Apache 2.2 will need to be updated to reflect Apache 2.4.

3. For SiteMinder configuration using the updated Apache version, please review information in SASŪ 9.4 Intelligence Platform: Middle-Tier Administration Guide, Fourth Edition
   For the updated Apache version delivered in this hot fix, step 2 under "Configuring SAS Web Server for the Web Agent" should read as follows:
   
   Edit the SAS-configuration-directory\Levn\Web\WebServer\conf\httpd.conf file. Add lines that are similar to the following at the beginning of the LoadModule directives:

   LoadModule sm_module "C:/Program Files (x86)/CA/webagent/bin/mod_sm24.dll"
   SmInitFile "C:/SAS/Config/Lev1/Web/WebServer/conf/WebAgent.conf"

   For UNIX deployments, the name of the library is libmod_sm24.so instead of mod_sm24.dll.

4. If you have configured TLS manually for SAS Web Server post-deployment, to use SAS Environment Manager to monitor SAS Web Server, complete the following steps:
   1. Edit the <SASConfig>/LevX/Web/WebServer/conf/httpd.conf file and make the following changes:

      Replace the line

      Listen 80

      with the following line:

      Listen localhost:7980

      IMPORTANT NOTE:  If you use a non-default port, please enter that port number instead of the one listed above

   2. Edit the <SASConfig>/LevX/Web/WebServer/conf/extra/httpd-ssl.conf file and make the following changes:

      Locate the following lines for the certificate file and key file and enter the correct filenames: SSLCertificateFile "ssl/myhost.crt"
      SSLCertificateKeyFile "ssl/myhost.key"
      SSLCertificateChainFile "ssl/myhost.crt

5. If you manually configured TLS for SAS Web Application Server, complete the following step

   1. Edit the <SASConfig>/LevX/Web/WebServer/conf/sas.conf file and add the following two lines:

      SSLProxyCheckPeerCN off
      SSLProxyCheckPeerName off

6. If you configured TLS for SAS Web Server and SAS Environment Manager is not configured for TLS and is also on the same machine as the Web Server, then complete this step if applicable:
   1. Edit the <SASConfig>/LevX/Web/WebServer/conf/sas.conf file and comment out the following directive:

      Replace the line

      Header set Strict-Transport-Security "max-age=31536000"

      with the following line:

      #Header set Strict-Transport-Security "max-age=31536000"

7. If your SAS Web Application Server is configured with FIPS enabled, then you will need to follow the information contained in SAS Note 61795

This completes the installation of hot fix B7Q002 on Linux for x64.
