[Return to top of section] [Return to top of document] [Table of Contents]

Instructions to update the server package with the NLS updates:

1. Replace the pcsnops.exe, adminstrings.dll, trcmsg.dll, tnsmsg.dll and pcstrcres.dll in the server package with those included in the respective language pack of nlspack.
   Example: If you are installing the fixpack on French Operating system then replace those modules from nlspack present under ..\FRA\ directory.
2. Copy the file PCCFGXXX.DLL, LDLCXXX.DLL, PCLVWXXX.DLL, PCMFCXXX.DLL and VACGFXXX.DLL from the NLS package directory to the server package directory. Note, this file will not exist in the server package because it is unique for each language.
3. Update the server INSTFIX.BAT file with an appropriate rename and copy statement for the pccfgxxx.DLL,ldlcXXX.DLL,pclvwXXX.DLL,pcmfcXXX.DLL and vacgfXXX.DLL modules. (where xxx reflects the language). See existing rename and copy statements in INSTFIX.BAT for format.

Perform the installation of the server package update. See section 3 for instructions.

Instructions to update the API client package with the NLS updates:

1. Replace the CSCENU.DLL,setco.exe, testlu62.exe and tracedg.exe in the client update package with those included from the appropriate sub-directory of this package.
2. Update the client INSTFIX.BAT file with an appropriate rename and copy statement present in the client.exe. See existing rename and copy statements in INSTFIX.BAT for format.

[Return to top of section] [Return to top of document] [Table of Contents]

Server Install instructions:

1. Install the server updates first, following the instructions in section 3.
2. Stop the CS/Windows node and all applications that use CS/Windows.
3. Copy nlspack.exe of Server, which is present in JR47512.EXE to a temporary directory.
4. Run the nlspack.exe, which will extract all the language packs.
5. Choose the appropriate NLS package based on the CS/Windows language that is installed, and Run the respective language pack.
   Example: If you wanted to install Simplified Chinese language pack then Run chs.exe -d
   This will create a sub-directory chs and extract all the files under chs directory for Simplified Chinese language.
6. Review the comments in the INSTFIX.BAT file for specific usage instructions. For example:
   • INSTFIX chs (no parameters; environment variables will be used to locate the installation location)
   • INSTFIX chs > nlsfp5.txt 2>&1 (silent install)
   • INSTFIX chs "C:\Program Files\IBM\Communications Server" (specify the directory)
   • INSTFIX chs "C:\Program Files\IBM\Communications Server" > nlsfp5.txt 2>&1 (silent install, specify directory)
7. Reboot and start the CS/Windows node.

NOTE:

1. INSTFIX.BAT checks if a PCOMM version less than 5.7 CSD3 is installed and if true, does not update the Trace Facility. CS/Windows 6.4 would use the Trace Facility installed by PCOMM. If you have installed PCOMM 5.9 or PCOMM 6.0 on CS/Windows 6.4, PCOMM will not install its Trace Facility. In this case, NLS_INSTFIX will update the CS/Windows 6.4 Trace Facility.
   If versions of PCOMM prior to 5.7 CSD3 are installed, you will not have any of the CS/Windows 6.4 Trace Facility updates or enhancements.
2. In order to use GSKit 8 please order GSKIT 8 media pack and install the product.
3. If the fixpack5 installed on top of CS/Windows v6.4.0.4 or V6.4.0.3 install then TN3270 SSL port may not get activated. To fix, please refer http://www.ibm.com/support/docview.wss?uid=swg21620127

SNA API Client Install instructions:

1. Install the client updates first.
2. Stop the all applications that use API-CLIENT.
3. Copy nlspack.exe of API Client, which is present in JR47513.EXE to a temporary directory.
4. Run the nlspack.exe, which will extract all the language packs.
5. Choose the appropriate NLS package based on the API Client language that is installed, and Run the respective language pack.
   Example: If you wanted to install Simplified Chinese language pack then Run chs.exe -d
   This will create a sub-directory chs and extract all the files under chs directory for Simplified Chinese language.
6. Review the comments in the INSTFIX.BAT file for specific usage instructions. For example:
   • INSTFIX chs "C:\Program Files\IBM\CS SNA API Client" (specify the directory)

New function added in FixPack 5
1. Support for GSKit v8 maintenance stream 8.0.50.5
	The Communications Server for Windows v6.4.0.5 media pack contains the full release level of the product that supports GSKit 8 level 8.0.50.5 . In addition to this support, GSKit 8 provides the ability to negotiate higher ciphers for SSL communinications with TN3270 clients. In order to use GSKit 8 level 8.0.50.5, you will need to order this media pack and install the product. The Fixpack 6.4.0.5 (Fixpack 5) does not contain the GSKit 8 release package.Hence, the product upgrade with fixpack will maintain at the GSK level, where the IBM Communications Server installed with media pack.

New function added in FixPack 4
1. RTP_TUNING Parameter Changes
	Communications Server for Windows v6.4.0.4 provides lower upper limits of two APPN protocol timers detailed below. MAX_SHORT_REQ_TIME: Required Keyword Type Unsigned Number Default 8000 Range 5-24000 Multiples Allowed? No The RTP protocol uses a timer called the Short Request Timer. The value of the timer is calculated as part of the protocol, but MAX_SHORT_REQ_TIME specifies a maximum value in milliseconds, beyond which the timer cannot increase. In some situations, setting this maximum value can improve performance. Setting a value of 0 means that the timer is not limited and can take any value calculated by the protocol. The minimum value is 5 milliseconds, with a default value of 8000 milliseconds. If the specified value is 1-4 milliseconds, a value of 5 milliseconds is used. MAX_REFIFO_TIME: Required Keyword Type Unsigned Number Default 4000 Range 5-12000 Multiples Allowed? No The RTP protocol uses a timer called the Re-FIFO Timer. The value of the timer is calculated as part of the protocol, but MAX_REFIFO_TIME specifies a maximum value in milliseconds, beyond which the timer cannot increase. In some situations, setting this maximum value can improve performance. Setting a value of 0 means that the timer is not limited and can take any value calculated by the protocol. The minimum value is 5 milliseconds, with a default value of 4000 milliseconds. If the specified value is 1-4 milliseconds, a value of 5 milliseconds is used.

New function added in FixPack 3
1. Support for GSKIT 8 and TLS 1.2
	The Communications Server for Windows v6.4.0.3 media pack contains the full release level of the product that supports GSKit 8 and TLS 1.2. In addition to this support, GSKit 8 provides the ability to negotiate higher ciphers for SSL communinications with TN3270 clients. In order to use GSKit 8 with TLS 1.2, you will need to order this media pack and install the product. The Fixpack 6.4.0.3 (Fixpack 3) does not contain the GSKit 8 release package.Hence, the product upgrade with fixpack will maintain at the GSK level, where the IBM Communications Server installed with media pack. The fixpack will support GSK TLS Renegotiation mentioned under New function added in Fixpack2.

New function added in FixPack 2
1. LU62 INIT SELF ENQUEUE Option
	When dependent LU6.2 sessions are activated from CS/Windows, an INIT-SELF message is sent to VTAM. In CS/Windows 6.4.0.2, the format of the INIT-SELF message was altered to not queue multiple INIT_SELF. If this LU62_INIT_SELF_ENQUEUE flag is set(LU62_INIT_SELF_ENQUEUE=1) then CS/Windows will use the Old format of the INIT-SELF which included the ENQUEUE parameter. The LU62_INIT_SELF_ENQUEUE in the .ACG file is part of the NODE definition. The following example shows the .ACG file entry. NODE=( ANYNET_SUPPORT=NONE CP_ALIAS=A DEFAULT_PREFERENCE=NATIVE DISCOVERY_SUPPORT=NO DLUR_SUPPORT=MULTI_SUBNET FQ_CP_NAME=A.A ARB_SUPPORT=ANY LU62_INIT_SELF_ENQUEUE=1 GVRN_SUPPORT=0 SUPPRESS_LUWID=0 NO_PUNAME_TO_HOST=0 DLUR_REX_PACING_SUPPORT=0 MAX_LOCATES=150 MAX_LS_EXCEPTION_EVENTS=200 NODE_ID=05D00000 NODE_TYPE=END_NODE REGISTER_WITH_CDS=1 REGISTER_WITH_NN=ALL SEND_TERM_SELF=0 SLI_CLOSE_SYNC_SUPPORT=0 TP_SECURITY_BEHAVIOR=VERIFY_EVEN_IF_NOT_DEFINED )
2. Support for GSKIT TLS Renegotiation weak security
	Along with this release, the GSKIT package used for handling SSL secure sessions has a vulnerability update also included in the refresh image. If the CS/Windows product is using TN3270 Server with SSL support enabled, then the GSKIT APAR should be applied or required to install CS/Windows freshly using the Fixpack2 refresh image. After installing CS/Windows 6.4.0.2 and gskbas-7.0.4.27, you can override the new default by setting appropriate value to the RENEGOTIATION key in the TN3270_PORT_DEF section in the config file. RENEGOTIATION takes the value NONE (default), ABBREVIATED, FULL. There are 3 possible functions of the gskit library. (a) NONE         : No renegotiation permitted   (b) ABBREVIATED  : Abbreviated renegotiation permitted (c) FULL         : Full (or abbreviated) renegotiation permitted. The default is NONE. TN3270_PORT_DEF=(      PORT=800      SECURITY=1      CLIENT_AUTHENTICATION=1      SECURITY_LEVEL=HIGH      RENEGOTIATION=NONE ) The Communications Server for Windows provides secure encryption and authentication for TN3270 Server clients by using Secure Socket Layer(SSL). The SSL support is provided by the GSKIT common component from IBM (package name gskta). Refer to the document, JR36023_TLS_SSLv3_Update_CS.pdf, provided with this APAR on Fix Central or on the CS/Windows media provided through Fix Central or Passport Advantage. The JR36023 APAR can be found on the Communications Server for Windows product under the brand "WebSphere" on Fix Central at: http://www.ibm.com/support/docview.wss?rs=2262&uid=swg1JR36023

New function added in FixPack 1
1. Active LUs Display
	Now, csdisplay can display all the LUs used by the LUA application or by the TN3270 Sessions with the new option of ALU. To check the active LUA & TN3270E session, type "csdisplay ALU" from the command Windows prompt. Example output of the "csdisplay ALU" as follows: a) When there is one LUA SSCP-LU and one LUA LU-LU Session active. csdisplay ALU LU Name        LUNAME05 PU Name        PUNAME NAU Address    5 Session Type   LU-LU LU Name        LUNAME09 PU Name        PUNAME NAU Address    9 Session Type   SSCP-LU Configured LUs         15 Active LUs                9 LUA(SSCP)             1 LUA(LU-LU)           1 TN3270(SSCP)        0 TN3270(LU-LU)      0 b) When there is one SSCP-LU TN3270 and one LU-LU TN3270 Session type. csdisplay ALU LU Name        BASELU02 PU Name        PUNAME NAU Address    2 Session Type   TN3270E SSCP-LU, 9.122.19.106 LU Name        BASELU03 PU Name        PUNAME NAU Address    3 Session Type   TN3270E LU-LU, 9.122.19.106 Configured LUs       15 Active LUs               9 LUA(SSCP)            0 LUA(LU-LU)          0 TN3270(SSCP)      1 TN3270(LU-LU)    1 c) When there is no SSCP Connected LUs or active LUA Application Sessions or active TN3270 Session. csdisplay ALU Configured LUs        15 Active LUs                9 LUA(SSCP)             0 LUA(LU-LU)           0 TN3270(SSCP)        0 TN3270(LU-LU)      0

[Return to top of section] [Return to top of document] [Table of Contents]

Installing the fixpack on the system:

1. Download JR47512.EXE in Binary format into a temporary directory.

2. Run the JR47512.EXE, which will extract Server.exe and nlspack.exe
3. Run Server.EXE with -d option to extract all server files. There are executables included in this package, those are required for fixpack installation. The instfix.bat in current directory is required only for the fixpack installation.
   1. If you have SNA API Client Services (Split-stack API Client/Server), copy API_Client.EXE in the client workstation and see section 4 for install instructions.
   2. nlspack.exe contains non-English language updates. Customers running non-English versions of CS/Windows also need to install NLSPACK package separately. To install the language pack refer section 2 for NLS install instructions.

4. New function updates have been included with this fixpack package. See section 3.2 for more details on the new updates.
   1. INSTFIX.BAT checks if a PCOMM version less than 5.7 CSD3 is installed and if true, does not update the Trace Facility. CS/Windows 6.4 would use the Trace Facility installed by PCOMM. If you have installed PCOMM 5.9 and above on CS/Windows 6.4, PCOMM will not install its Trace Facility. In this case, INSTFIX will update the CS/Windows 6.4 Trace Facility.

      If versions of PCOMM prior to 5.7 CSD3 are installed, you will not have any of the CS/Windows 6.4 Trace Facility updates or enhancements.

      There is a problem with some versions of PCOMM prior to 5.7 CSD3 where using ADD/REMOVE PROGRAMS to remove PCOMM removes the Service APPNNODE from the REGISTRY. CS/Windows will NOT run successfully without this registry entry. While this problem has been resolved in later PCOMM versions you can do the following to address the problem.

      The recommended procedure in this situation is as follows:

      1. Remove PCOMM using Add or Remove Programs
      2. Remove CS/Windows 6.4
      3. Re-install CS/Windows 6.4
      4. Install PCOMM 5.9 (or PCOMM 5.7 CSD3 or later)
      5. Apply CS/Windows 6.4 Fixpack4 maintenance upgrade

5. Stop Communications Server for Windows (including your node, Node Operations, Node Configuration, Log Viewer, and any other CS/Windows components you have started). Note that there may still be CS/Windows-related services running on the machine after stopping these applications, but this is normal and should not affect the installation of this fix pack package.
   1. Stop ALL Window applications on this box since a reboot will be required after running INSTFIX.BAT maintenance installation.
   2. Refer the INSTFIX.BAT for details on various installation options.

   INSTFIX.BAT can be run with the following options to preserve output to a log file, such as for silent install including errors in the log.

   INSTFIX > FIX_PACK_5.TXT 2>&1

   NOTE 1: INSTFIX.BAT issues
   "NET STOP APPNNODE" to stop APPNNODE Services.
   "NET STOP LDLCSERV" to stop LDLCSERV Services.
   "CSTRACE STOP" and "CSTRACE SHUTDOWN" to stop CSTRCSER trace Service.

   NOTE 2: INSTFIX will rename the current or target files being replaced to &file.pre6405, then copy the updated files.

   If for some reason you rerun INSTFIX.BAT, you will receive errors during each rename because the &file.pre6405 file will already exist. The original copy of the file will be preserved in &file.pre6405 and available as a backup for restore purposes.

   If for some reason you need to restore or back out this fixpack, you would have to manually rename the updated file names and restore the original files.

   NOTE 3: After all the files are copied, INSTFIX.BAT automatically issues
   "SERVICESTEST -c LDLCSERV" command to initialize LDLCSERV service.
   "NET START LDLCSERV" to start LDLCSERV service.

   NOTE 4: The default value of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\IBM\Communications Server\CurrentVersion\VersionNumber will be changed to 6405.

6. After running INSTFIX.BAT, confirm ALL component reflect new dates. If they do NOT, then you must manually copy them after you REBOOT but prior to starting any IBMCS Services. ALL files must reflect updated dates or IBMCS will not function properly.

7. If you want to restrict the user(Non-Administrator) from controlling SNA resources like Stopping/Starting the node/link etc., you have to run the batch file below and follow the step (B) mentioned below.

1. Run the batch "AccessControlSettings.bat"
2. If you are running Windows XP or 2003 and above do the following: (For Windows NT and 2000, skip this step.)
   1. Run regedit to start the registry editor (start->run then type regedit).
   2. Navigate to HKLM\Software\IBM\Communications Server
   3. Right-click on Communications Server and select Permissions.
   4. Click the "Add" button.
   5. Click the "Advanced" button.
   6. Click the "Find Now" button.
   7. Select "IBMCSADMIN" from the resulting list and click the "OK" button.
   8. Click the "OK" button.
   9. Select "IBMCSADMIN" from the list.
   10. Check the appropriate box to allow "Full Control".
   11. Click the "OK" button.
   12. Navigate to HKLM\Software\IBM\OEM_CONFIG and repeat the steps from "3" to "11".
   13. Exit the registry editor.
8. Shutdown and Restart WINDOWS to reboot the machine.

9. You can now start IBMCS Node Operations and configure the new available functions.
