RSE server installation, updates, and uninstall

Installing

Use IBM Installation Manager to install the RSE server.

Note: You can also use Installation Manager to install updates for the RSE server or to roll back a previously installed update (see Updating).

Terms used: In the following instructions:

The "server system" is the host system on which you are installing the RSE server.
The "client system" is the system from which you are viewing and controlling the Installation Manager.

You can run the Installation Manager in either of two ways: using the X Window System or using the silent mode of Installation Manager. These methods are described in the next two subtopics.

Installation with the X Window System

Copy the installation file, rdzrse80.tar, from the installation CD to a writable file system directory on the server system (/tmp would be a good location).
- The installation CD is titled IBM Rational Developer for System z RSE server for AIX, Linux, and Linux on System z Installation CD.
- The CD has three directories, AIX, Linux, and zLinux that contain the rdzrse80.tar file specific to the target OS. Pick the appropriate file from the directory that matches the OS on the server system.
Extract the RSE server install image:
```
tar -xvf rdzrse80.tar
```
Connect the client system to the server system. Here are two methods for connecting the systems:
- Connect a console to the server; or
- On the client system, start an X Window System server to display the Installation Manager and follow these steps:
  1. Set the DISPLAY variable on the server system to the host name and port of a third system. For example, if you are running csh on the server system, enter the following command on the csh command line:
```
setenv DISPLAY client_system:port
```
    where client_system is the host name of the client system and port is a valid port. For example:
```
setenv DISPLAY myclient:0
```
  2. Start the X Window System server on the third system.
On the system running the X Window System, enter the following command on the command line:
```
xhost +server_system
```
where server_system is the host name of the server system. For example:
```
xhost +myserver
```
This command tells the X Window System to accept a display stream from the server system.
Start the Installation Manager. On the command line:
1. Change to the directory where you unpacked the rdzrse80.tar file.
2. Enter the install command to start the Installation Manager:
```
install
```
Follow the directions in Installation Manager to complete the installation.

Installation using silent mode

This method uses the silent mode capability of the Installation Manager. For more information about silent mode see the IBM Information Center for the Installation Manager at http://publib.boulder.ibm.com/infocenter/install/v1r4/index.jsp.

Note: Run the Installation Manager as the root user.

Copy the installation file, rdzrse80.tar, from the installation CD to a writable file system directory on the server system (/tmp would be a good location).
- The installation CD is titled IBM Rational Developer for System z RSE server for AIX, Linux, and Linux on System z Installation CD.
- The CD has three directories, AIX, Linux, and zLinux that contain the rdzrse80.tar file specific to the target OS. Pick the appropriate file from the directory that matches the OS on the server system.
Extract the RSE server install image:
```
tar -xvf rdzrse80.tar
```
On the command line, change to the directory where you unpacked the rdzrse80.tar file.
The default install directory for the RSE server is /opt/IBM/RDz80. To select another install directory:
1. Open the install.xml response file with a text editor.
2. Find the <profile> element.
3. Change the installLocation parameter to specify the install directory that you want to use. For example:
```
<profile
    id="IBM Rational Developer for System z Remote Systems Explorer"
    installLocation="rse_directory">
</profile>    
```
  where rse_directory is the directory in which you want to install the RSE server.
4. Close the text editor.
If you are installing multiple RSE server instances onto the system, you must specify a unique identifier and a unique install location for each instance of the server. To specify a unique identifier and install location:
1. Open the install.xml response file with a text editor.
2. Make the following changes to the <profile> element:
  1. Change the id parameter to specify the install name that you want to use for this instance of the server.
  2. Change the installLocation parameter to specify the install location for this instance of the server. For example:
```
<profile
    id="IBM Rational Developer for System z Remote Systems Explorer_1"
    installLocation="/opt/IBM/RDz80_1">
</profile>
```
    where the _1 suffix is used to make the values unique.
3. Also change the <offering> element so that the profile parameter has the same value as the id parameter of the <profile> element. For example:
```
<offering profile="IBM Rational Developer for 
        System z Remote Systems Explorer_1"
        id="com.ibm.rational.rdz.rseserver.v80"
        version="8.0.3.2011"/>
```
4. Close the text editor.
To run the Installation Manager, enter the following command on one line. On AIX:
```
install --launcher.ini silent-install.ini  -acceptLicense
```

Directories created

Directories created: Installation Manager creates the following directories:

/opt/IBM/RDz80 contains the RSE server program. (This is the default location.)
/opt/IBM/InstallationManager is the directory where Installation Manager is installed.
/var/ibm/InstallationManager contains various files used by Installation Manager such as log files, configuration files, and license file.
/opt/IBM/SDPShared contains the shared resources for products installed using Installation Manager.

Uninstalling

Use IBM Installation Manager to uninstall the RSE server:

With the X Window System:
1. Set up and start the X Window System as described in the subtopic Installation with the X Window System.
2. Find the directory where the Installation Manager is installed. The default location is /opt/IBM/InstallationManager.
3. Start Installation Manager:
  1. Change to the directory where you installed Installation Manager.
  2. Change to the eclipse subdirectory.
  3. Start the executable file IBMIM. This is Installation Manager.
4. In Installation Manager:
  1. Click Uninstall.
  2. Follow the directions to uninstall the RSE server.
Using silent mode:
1. On the command line, change to the directory where Installation Manager is installed. The default location is /opt/IBM/InstallationManager.

3. Enter the following command on one line:
```
./IBMIM --launcher.ini silent-install.ini 
                  -input rse_directory/uninstall/uninstall.xml
```
  where rse_directory is the path of the directory where the RSE server is installed. The default installation directory is /opt/IBM/RDz80.

Updating

Use IBM Installation Manager to update the RSE server.

Note: The update process makes backup copies of the current configuration files in the subdirectory backup within the installation directory. You might also want to make your own backup copies of any configuration files that you have modified to ensure that you can easily restore the files after the update is complete.

With the X Window System:
1. Set up and start the X Window System as described in the subtopic Installation with the X Window System.
2. Copy the tar file containing the update information into a writable file system directory on the target system (/tmp would be a good location).
3. Extract the update information from the update tar file. For example:
```
tar -xvf rdzrse80.tar
```
  where rdzrse80.tar is the tar file containing the update information.
4. Find the directory where the Installation Manager is installed. The default location is /opt/IBM/InstallationManager.
5. Change to the eclipse subdirectory.
6. Start the executable file IBMIM. This is Installation Manager.
  Note: You must run the Installation Manager as the root user.
7. In Installation Manager:
  1. Add a new repository specifying the path where the update files are located:
    1. Click File > Preferences to open the Preferences window.
    2. In the left pane click Repositories.
    3. Click Add Repository.
    4. In the directory where the tar file was expanded, change to subdirectory RSE and then select the file repository.config.
      Note: For example, if the tar file was expanded in directory /tmp/RDz803, then select /tmp/RDz803/RSE/repository.config.
    5. Click OK.
    6. Click OK again to close the Preferences window.
  2. Click Update.
  3. Follow the directions to update the RSE server.
Using silent mode:
The process for updating an installed version of the RSE server is similar to the process for installing the server. Follow these steps:
1. Copy the tar file containing the update information into a writable file system directory on the target system (/tmp would be a good location).
2. Extract the update information from the update tar file. For example:
```
tar -xvf rdzrse80.tar
```
  where rdzrse80.tar is the tar file containing the update information.
3. In the install.xml response file, set the correct values for the unique identifier and the unique install location of this instance of the server:
  1. If you are not sure of the correct values you can determine them as follows:
    1. Start the Installation Manager. (This must be the same instance of Installation Manager that was used to install this instance of the RSE server.)
    2. Click File > View Installed Packages.
    3. In the list of Installed Packages, select the instance of the RSE server that you want to update.
    4. Look in the Details section to find the identifier and the install location of this instance of the server:
      - The identifier is the title of the package group, printed immediately after the heading Details.
      - The install location is printed in the bulleted list following the words Installation Directory.
    5. Close the Installation Manager.
  2. Go to the directory where you unpacked the tar file.
  3. Open the install.xml response file with a text editor.
  4. In the <profile> element set the correct values for the id and installLocation parameters. The following example shows the default values:
```
<profile 
    id="IBM Rational Developer for System z Remote Systems Explorer" 
    installLocation="/opt/ibm/RDz80">
</profile>
```
  5. In the <offering> element set the correct value for the profile parameter. The value should be the same as the value that you set for the id parameter of the <profile> element. For example:
```
<offering profile="IBM Rational Developer for 
        System z Remote Systems Explorer" 
        id="com.ibm.rational.rdz.rseserver.v80" 
        version="8.0.3.2011"/>
```
  6. Close the text editor.
4. To run the Installation Manager, enter the following command on one line. On AIX:
```
install --launcher.ini silent-install.ini
```
  Note: You must run the Installation Manager as the root user.

RSE directory configuration

Important: After the RSE server has been installed on a host system, only the root user can log in to the host system.

To allow other users to log in to the system, the system administrator must grant read and execute permissions on the directory where the RSE server is installed and on all the files and subdirectories within that directory.

To grant permissions to the owning user (root) and to all users in the root group, enter the following command at the command line:

 chmod -R ug+xr  rse_directory

where rse_directory is the path of the directory where the RSE server is installed. The default path is /opt/IBM/RDz80.

Note: This example assumes that the RSE server is the only product installed in the directory.

To grant permissions to every user on the system, enter the following command at the command line:

 chmod -R ugo+xr  rse_directory

where rse_directory is the path of the directory where the RSE server is installed. The default path is /opt/IBM/RDz80.

Note: This example assumes that the RSE server is the only product installed in the directory.

Starting the RSE server

To start the RSE server:

Open the ksh shell. Do not use any other command shell, such as csh, bash, or sh.
Change to the directory where the RSE server is installed.
Enter the following command:
```
perl ./daemon.pl [port]
```

where port is the number of the port on which you want the RSE server to listen.

Note: The default port is 4075.

Examples:

To start the RSE server and have it listen on the default port, enter:
```
perl ./daemon.pl
```
To start the RSE server and have it listen on port 4080, enter:
```
perl ./daemon.pl 4080
```

Example: RSE server start

The following example shows what the command line interface looks like when the RSE server is started successfully. The first line is the command to start the server and the second line is output from that command:

# perl ./daemon.pl 4080

Daemon running on: RDzServer.ibm.com, port: 4080

In this example the host name of the system is RDzServer and the port specified is 4080.

Configuring the RSE server to use SSL

You can configure the RSE server to use SSL authentication to provide secure connections between the server and its clients. To configure the RSE server to use SSL authentication follow these steps:

Create a Java keystore file on the system where the RSE server is installed.
Use the keytool program provided with the Java SDK to generate a key pair (public key and associated private key). For example:
```
keytool -genkey -alias alias_name -validity 3650 -keystore keystore_name 
    -storepass keystore_password -keypass key_password
```
where:
- alias_name is the name of the keystore.
- keystore_password is the password for the keystore.
- key_password is the password for the key.
In the RSE server install directory, update the ssl.properties file:
1. Open the ssl.properties file with a text editor.
2. Specify the location of the Java keystore file and the password:
```
daemon_keystore_file=jks_file
daemon_keystore_password=jks_password 
```
  where:
  - jks_file is the path of the Java keystore file that you created, and
  - jks_password is the password for the Java keystore file.
3. Set the following two properties to enable SSL authentication:
```
enable_ssl=true
disable_server_ssl=false
```
4. Close the ssl.properties file.
Start the SSL Server in the usual way.

Example: RSE server start with SSL

The following example shows what the command line interface looks like when the RSE server with SSL is started successfully. The first line is the command to start the server and the subsequent lines are output from that command:

# perl ./daemon.pl 4080

SSL Settings
[daemon keystore:       /opt/IBM/RDz80SSL/rdzrse.jks]
[daemon keystore pw:    MyKeystorePassword]
[server keystore:       /opt/IBM/RDz80SSL/rdzrse.jks]
[server keystore pw:    MyKeystorePassword]
Daemon running on:      RDzServer.rtp.raleigh.ibm.com, port: 4080

Secure and nonsecure sessions

If you want to concurrently run both secure sessions and nonsecure sessions, you must install a second instance of the RSE server and configure the ssl.properties file in the new installation directory. You cannot use a single instance of the server to run both secure sessions and nonsecure sessions concurrently.

For example, suppose that you have installed the RSE server in the default directory and you have configured it to run nonsecure sessions using the default port 4080. Now you want to install a second instance of the server and configure it to run secure sessions using port 4077. Follow these steps:

Install a second instance of the RSE server into a new installation directory, such as /opt/IBM/RDz80SSL.
In the installation directory, modify the ssl.properties file as described in the topic Configuring the RSE server to use SSL:
```
daemon_keystore_file=jks_file
daemon_keystore_password=jks_password 

enable_ssl=true
disable_server_ssl=false
```
Start the server, using a different port than the port used for nonsecure connections:
```
# perl ./daemon.pl 4077
```

RSE server startup at system boot

This topic describes how to start the RSE server daemon automatically when the system boots.

The following example assumes that two instances of the RSE server are installed and configured as follows:

The RSE server is installed in directory /opt/ibm/RDz80 and uses port 4080. It is configured not to use SSL.
Another copy of the RSE server installed in directory /opt/ibm/RDz80SSL, uses port 4077, and is configured to use SSL.

To start these two instances of the RSE server automatically when the system boots, follow these steps:

Create a script file to start the non-SSL RSE server:
1. Create a new script file named /opt/IBM/RDz80/RDzRSE4080.sh.
2. Add these lines to the script:
```
#!/bin/ksh
cd /opt/IBM/RDz80
perl /opt/IBM/RDz80/daemon.pl 4080 2> /tmp/RDzRSE4080.log &
```
3. Close the script file.
4. Run the following command to make the script file executable:
```
chmod u+wrx /opt/IBM/RDz80/RDzRSE4080.sh
```
Create a script file to start the SSL RSE server:
1. Create a new script file named /opt/IBM/RDz80SSL/RDzRSESSL4077.sh.
2. Add these lines to the script:
```
#!/bin/ksh
cd /opt/IBM/RDz80SSL
perl /opt/IBM/RDz80SSL/daemon.pl 4077 2> /tmp/RDzRSESSL4077.log &
```
3. Close the script file.
4. Run the following command to make the script file executable:
```
chmod u+wrx /opt/IBM/RDz80SSL/RDzRSESSL4077.sh
```
Update the file /etc/inittab to start the two servers when the system boots:
1. To add entries for the two RSE servers to /etc/inittab enter these two commands at the command line:
```
mkitab "RDzRSE80:2:once:/opt/IBM/RDz80/RDzRSE4080.sh"
mkitab "RDzRSE80SSL:2:once:/opt/IBM/RDz80SSL/RDzRSESSL4077.sh"
```
2. To verify that these two entries have been added to /etc/inittab, enter the following command:
```
lsitab -a
```
  The output from this command indicates that the two entries have been added.
  Note:
  If you need to remove the two entries from the /etc/inittab enter the following:
```
rmitab RDzRSE80
rmitab RDzRSE80SLL
```
Use the following command to reboot the system and start the RSE servers:
```
shutdown -r
```

Debugging AIX programs using Developer for System z

Compile the source code into object files with debug enabled.
Link the object files into an executable that can be debugged.
Run the executable. Start the AIX debugger in the same directory with the program to debug.
```
irmtdbgc -qhost=RDzSystem -quiport=8000 yourApp
```
In the Developer for System z debug perspective, start the Debug UI daemon listening on the same port as irmtdbgc.
