IMPORTANT NOTES

1. Files delivered in this hot fix will be backed up during the installation process. However, it is good general practice to back up your system before applying updates to software.

2. You must have Administrator Privileges on your CLIENT or SERVER machine.

3. All currently active SAS sessions, daemons, spawners and servers must be terminated before applying this hot fix.

4. This hot fix should be installed using the same userid who performed the initial software installation.

5. CONFIGURATION: No automatic configuration scripting is included for this hot fix. If you have previously configured software installed, the SAS Deployment Manager may present a screen where you will see "Apply SAS Hot Fixes" and "Configure SAS Hot Fixes" options. On this screen, you must ensure that the "Configure SAS Hot Fix" option is *not* selected. If this option is automatically selected, please de-select it prior to proceeding with the SAS Deployment Manager Screens. Failure to do so could have unintended consequences when applying this hot fix.

PRE-INSTALLATION INSTRUCTIONS

1. On the Midtier machine - open the file
   <SASConfig>/Lev1/Web/WebAppServer/SASServer8_1/sas_webapps/sas.insuranceriskmanagementserver.war/WEB-INF/picklist
   and search the file for the line:
   

   name=sas.solutions.risk.irm.server
   

   Below this line you will find the version number of sas.solutions.risk.irm.server jar file. For example:
   

   version=306005.13.0.20240229114600_f0irm36p

2. Go to the folder <SASHome>/SASVersionedJarRepository/eclipse/plugins and search for the sas.solutions.risk.irm.server jar that matches the version number.
   For example:
   

   sas.solutions.risk.irm.server_306005.13.0.20240229114600_f0irm36p.jar.

   Remove this file from the folder or move it to a different archive folder.

INSTALLATION

The hot fix will be applied using the SAS Deployment Manager. By default, the SAS Deployment Manager will search in the <SASHOME>/InstallMisc/HotFixes/New directory for hot fixes to be applied, but will also prompt for a location if you have downloaded hot fixes to a different directory.

After downloading G2T016pt.zip, follow the instructions for applying hot fixes in the SAS Deployment Wizard and SAS Deployment Manager 9.4: User's Guide.

Please review the CONFIGURATION Important Note above concerning proper selection of the "Configure SAS Hot Fix" option in the SAS Deployment Manager.

The hot fix installation process generates the log file

<!SASHOME>/InstallMisc/InstallLogs/IT_date-and-time-stamp.log

Postexec log files are created after the installation is completed and identifies the files that were added, backed up, changed and removed. These log files include the 'member' hot fix id in the name of the file and are also written to the <!SASHOME>/InstallMisc/InstallLogs directory. There is one postexec log for each 'member' hot fix applied (member hot fixes are listed at the top of these instructions).

The content of this hot fix is listed in the hot fix manifest.

Security Update

SAS Security Updates are applied during the initial installation of your software. In order to maintain the latest level of security offered by SAS, security updates should be applied and/or re-applied after any changes to your software, including installation of hot fixes. The current SAS Security Updates for all releases of SAS are available at https://tshf.sas.com/techsup/download/hotfix/HF2/SAS_Security_Updates.html. Please re-apply security updates in accordance with the SAS Security Updates and Hot Fixes document available on the SAS Security Updates web page.

POST-INSTALLATION INSTRUCTIONS

2. Hot Fix Post Installation steps to Rebuild and Redeploy Web Applications

   This hot fix requires post-installation steps that will update the web application deployed to your application server. For more information about how to rebuild and redeploy Web Applications, see the SAS® 9.4 Intelligence Platform, Middle-Tier Administration Guide, Chapter 8 Administering SAS Web Applications on Rebuilding the SAS Web Applications and Redeploying the SAS Web Applications.

   1. Rebuild Web Applications

      NOTE: In order for this step to execute correctly, the Metadata Server must be running.

      Select the appropriate product as the Web Application to Rebuild

   2. Re-start all SAS sessions, daemons, spawners and servers. For more information on the proper order for starting servers, go to SAS® 9.4 Intelligence Platform: System Administration Guide, Fourth Edition and review the section entitled "Starting, Stopping and Checking the Status of Servers".

   3. Redeploy Web Applications Redeploy the updated wars to the web application server.

   4. Apply Python changes to the platform federated area
      
      1. Copy file irm_exec_pytask.py
         from
             <SASHome directory>/SASFoundation/9.4/misc/rmifirmmva/fa.0.3.6/source/python/nodes/
         to
         the SAS Infrastructure for Risk Management platform FA replacing the old file.
             <SAS Config directory>/Lev1/AppData/SASIRM/fa.0.3.6/source/python/nodes/
         

      2. Copy "irm-3.6-py2.py3-none-any.whl" (with md5 checksum 411f18be509546992c6a97a129f6b3db)
         from
             <SASHome directory>/SASFoundation/9.4/misc/rmifirmmva/fa.0.3.6/client_packages/
         to
         the SAS Infrastructure for Risk Management platform federated area folder
            <SAS Config directory>/Lev1/AppData/SASIRM/fa.0.3.6/client_packages.

      3. Restart the SAS Infrastructure for Risk Management midtier

   5. All Python developers will need to update the wheel package on their local machine:
      
      1. Uninstall the SAS Infrastructure for Risk Management wheel package in the local machine by using pip: pip uninstall irm

      2. Reinstall the SAS Infrastructure for Risk Management wheel package by following the instructions in
         Download the SAS Infrastructure for Risk Management Wheel Package

   6. After applying the hot fix customers running a large number of parallel cycles might still encounter issues. Hence, the following configuration parameters need to be set, depending on the site hardware.
      1. Increase the JVM heap size and http connections in the JVM_OPTS parameter list in the setenv.bat file for SASServer8_1. After implementing the JVM parameter perform a restart of the SASServer8_1 for the changes to be in effect.

                -Dsas.svcs.http.max.total.connections=1024
                -Dsas.svcs.http.max.connections=1024
                -Xss should be set to 256k
                - Increase JVM heap -Xmx and -Xms value to 12G or 12288M
         

      2. Add the following parameters in SAS IRM Mid-Tier Server. Go to

         SAS Management Console -> Expand Application Management -> Expand Configuration Manager -> Expand SAS Application Infrastructure ->

                com.sas.solutions.risk.irm.gemfire.lock-lease=600
                com.sas.solutions.risk.irm.gemfire.lock-timeout=240
                com.sas.solutions.risk.irm.gemfire.search-timeout=1200
         

      3. Increase max_connections to 2000 in the following Postgres Database Server configuration section as mentioned below. Find the postgres configuration file in the following path on the machine where Postgres Database services are running.

         <SASConfig>/Lev1/RiskGovernanceFrameworkDataServer/data/postgresql.conf
         <SASConfig>/Lev1/WebInfrastructurePlatformDataServer/data/postgresql.conf
         

                ## postgresql.conf ##
                #------------------------------------------------------------------------------
                # CUSTOMIZED OPTIONS
                #------------------------------------------------------------------------------
                # Add settings for extensions here
                max_connections = 2000
