# Installing StreamBase on Linux

This page describes the installation of the TIBCO StreamBase® base kit on supported Linux platforms. The base kit for Linux includes the StreamBase Deployment Runtime and support files for the StreamBase Client API.

## Before You Install

Before you install TIBCO StreamBase, use the following checklist to make sure each target machine matches the prerequisites.

| Read through the Release Notes for the current release to look for any late-breaking information about installing StreamBase on Linux.
| You may need to uninstall an existing StreamBase installation before proceeding. You must do this if you are installing a service pack (``n.m.x``, where ``x`` changes) for an existing StreamBase installation. See Uninstalling StreamBase on Linux.
| Confirm that the target machine is running a supported Linux distribution with the latest updates. See Supported Configurations.
| Confirm that the target machine's RAM and disk space requirements meet or exceed the minimums listed on Supported Configurations.
| Confirm that you have root access on the target machine if you plan to install StreamBase in the default location, `/opt/tibco/sb-cep/`n.m``, or in another location that requires root access.
| Be prepared to configure the shell environment for all users and any server processes that want to take advantage of StreamBase and Live Datamart services. Follow the instructions in Shell Settings for Linux.
| The mvn command bundled with StreamBase must detect a java command at the operating system level, independent of the JDK bundled with StreamBase. You can configure your shell environment to use the StreamBase JDK as your system Java, or you can install separate JDK.
| Important! The StreamBase installer cannot finish installing if this library is not found. On newer Linux distributions, install the Linux package that provides GCC 3.3 compatibility to support a Reuters library included with StreamBase. For example, install `compat-libstdc++-33`.

## Installation Options for Linux

The Linux installer for StreamBase is provided in two forms:

- A set of RPM installation files (`rpm-bin`) wrapped in a shell script.

- A tar.gz archive file (`archive-bin`) wrapped in a shell script.

In both cases, you run the wrapper shell script, which selects a destination folder, displays license information and prompts for acceptance, and then installs the component files. The RPM installer also runs a few configuration steps after installing its files. The archive installer only installs files.

The Linux distributions supported by TIBCO supports RPM installers. TIBCO Software recommends using the RPM installer.

Continue with the instructions in one of the following sections:

- Installing wth the RPM Installer

- Partial RPM Installation

- Installing with the Archive Installer

## Installing with the RPM Installer

As downloaded from the TIBCO distribution site, the StreamBase RPM installer is delivered in a single file named with the following pattern:

- `TIB_sb-cep_`version`_linux_x86_64.rpm-bin`

where `version` represents the release number in `major`.`minor`.`servicepack` format. The installer file includes StreamBase Studio, StreamBase Server, client utilities, tools and APIs, and documentation.

Install the RPM version of the StreamBase base kit installer with these steps (substituting the actual version number, such as `10.3.0`, for ``version``):

1. Log in as root, or prefix the installer script command with sudo.

2. If you copied the installer file from another location, it may have lost its executable permission in the copy. Restore executability with a command like the following:

       chmod +x TIB_sb-cep_version_linux_x86_64.rpm-bin

3. Run the installer wrapper script with:

       ./TIB_sb-cep_version_linux_x86_64.rpm-bin

   Installing with RPMs stops any StreamBase service, if it one currently running, as installed by a previous StreamBase release.

4. The wrapper script prompts for the path to an installation directory. For a standard installation, press Enter to accept the default, `/opt/tibco/sb-cep/`n.m``.

   If you install into a custom installation directory, the installation will not be complete; links in `/usr/bin` must be removed and corrected by following the procedure in Making Symbolic Links for StreamBase Commands.

   If the script detects an existing RPM installation in the target directory, it displays a notice that it will upgrade the existing installation. If the script detects an existing Archive installation, it halts the installation and prompts you to remove the existing installation first.

5. The wrapper script displays the text of the TIBCO StreamBase license. Press Space to page through the license text.

6. The script prompts Do you accept this license agreement? Type `yes` and press Enter.

7. The RPM installer then extracts and installs the installation files.

8. When done, the script prompts: Installation complete.

## Partial RPM Installation

The StreamBase RPM installer contains five RPM installers bundled into one installer. The five component RPMs are the following:

- `streambase-client-*.rpm` — installs the client utilities such as sbc, sbfeedsim, and others.

- `streambase-devel-*.rpm` — installs tools and APIs that let you write StreamBase extensions.

- `streambase-docs-*.rpm` — installs the documentation.

- `streambase-server-*.rpm` — installs StreamBase Server.

- `streambase-studio-*.rpm` — installs StreamBase Studio.

There may be occasions when you only need to install a portion of the full set. The `streambase-server` and `streambase-devel` packages each require the `streambase-client` package to be installed. Other than these requirements, you can install any combination of RPMs.

For example, to install only StreamBase Server without Studio, you only need to install the `streambase-server` and `streambase-client` RPMs. To do this, first extract the RPMs from the `streambase-rpms-*.bin` installer with a the following steps:

1. Log in as root (or run the following commands with sudo).

2. If you copied the installer file from another location, it may have lost its executable permission. Restore executability with a command like the following:

       chmod +x TIB_sb-cep_version_linux_x86_64.rpm-bin

3. Run the installer wrapper script with the `unpack` argument:

       ./TIB_sb-cep_version_linux_x86_64.rpm-bin unpack

4. The wrapper script prompts for the path to an installation directory and suggests the current directory by default. Accept the suggestion or specify a relative path to a temporary directory.

5. The wrapper script displays the text of the StreamBase license. Press Space to page through the license text.

6. The script prompts Do you accept this license agreement? Type `yes` and press Enter.

7. The archive installer then extracts the installation files to the specified temporary directory.

8. When done, the script prompts: Installation complete.

Next, use an rpm command to install the packages of interest. For example:

    rpm -ivh streambase-server-*.rpm
    rpm -ivh streambase-client-*.rpm

## Installing with the Archive Installer

The StreamBase archive installer is delivered in a single file named with the following pattern:

- `TIB_sb-cep_`version`_linux_x86_64.archive-bin`

where `version` is the release number.

Install the archive version of the StreamBase base kit installer with the following steps:

1. If you intend to install to the default location in `/opt`, log in as root, or prefix the installer commands below with sudo.

2. If you copied the installer file from another location, it may have lost its executable permission in the copy. Restore executability with a command like the following:

       chmod +x ./TIB_sb-cep_10.0.0_linux_x86_64.archive-bin

3. You can install a new major (``n``) or minor (`n.m`) release of StreamBase alongside of an existing installation, in a separate directory that does not already contain a StreamBase installation. Be aware that you can only install multiple versions by using archive installers, and that you cannot install more than one service pack (``n.m.x``) release for a given minor (``n.m``) release.

4. Run the installer wrapper script with a command like the following:

       ./TIB_sb-cep_7.4.0_linux_x86_64.archive-bin

5. The script checks for a compatible platform and architecture, and warns if you are installing the wrong version for the current platform.

6. The wrapper script proceeds to install in the standard location, `/opt/tibco/sb-cep/`n.m``.

   If the script detects an existing installation in the target directory, it halts the installation and prompts you to remove the existing installation first.

   If you do not have root rights on a shared development machine, you can install for evaluation and testing purposes in a home directory subfolder. In this case, specify the full, absolute path to the alternate directory. The installer script does not recognize environment variable expansion or the tilde (~) shortcut. Specify a full path such as the following:

       /home/sbuser/apps/streambase

7. The wrapper script displays the text of the StreamBase license. Press Space to page through the license text.

8. The script prompts Do you accept this license agreement? Type `yes` and press Enter.

9. The archive installer then extracts and installs the installation files.

10. When done, the script prompts: Installation complete.

## Partial Archive Installation

The archive installation file contains a number of `tar.gz` files, one for the base StreamBase installation and others for LiveView components and additional adapters. You can unpack the archive installation file into its component `tar.gz` files by appending the `unpack` argument when running the installer script:

1. Log in as root, or prefix the installer script command with sudo.

2. If you copied the installer file from another location, it may have lost its executable permission in the copy. Restore executability with a command like the following:

       chmod +x ./TIB_sb-cep_7.4.0_linux_x86_64.archive-bin

3. Run the installer wrapper script with the `unpack` argument:

       ./TIB_sb-cep_7.4.0_linux_x86_64.archive-bin unpack

4. The wrapper script prompts for the path to an installation directory and suggests the current directory by default. Accept the suggestion or specify a relative path to a temporary directory.

5. The wrapper script displays the text of the StreamBase license. Press Space to page through the license text.

6. The script prompts Do you accept this license agreement? Type `yes` and press Enter.

7. The archive installer then extracts the installation `tar.gz` files to the specified directory.

8. When done, the script prompts: Installation complete.

The contents of each `tar.gz` file is a directory structure rooted at the relative directory `streambase`. This lets you un-tar the `tar.gz` files to any location you choose.

## Installing Additional Features

Additional adapters or extra features may have their own separate installer files, which are provided in either `.rpm-bin` or `.archive-bin` formats.

### Note

You must use the same installer type for adapters as you used for the base kit. That is, if you installed the base kit with the RPM installer, you must install adapters with the RPM installer, and likewise for the `.archive.bin` installers.

StreamBase framework installers look for a matching StreamBase base release, and only allow installation of the framework into that base release's directory. By contrast, an external adapter can be installed on a machine that does not have StreamBase installed on it, so the choice of location directory is more flexible.

As download from the TIBCO distribution site, the installers are delivered in a single file named with the following pattern:

- TIB_`productid`_`major`.`minor`.`servicepack`_linux_x86_64.archive-bin — Archive (Tarball) installer in a shell wrapper

- TIB_`productid`_`major`.`minor`.`servicepack`_linux_x86_64.rpm-bin — RPM-based installer in a shell wrapper

where `productid` identifies the adapter or framework, `major`, `minor` and `servicepack` identify the specific release.

After completing the installation of StreamBase on Linux, next install any external adapter or framework for which you have a license, using its separate installer.

RPM Installer. After the StreamBase base kit is installed, you can install an external adapter or LiveView component with its RPM installer, using a command like the following examples, run as root:

    rpm -ivh TIB_sb-ad-flume_7.4.3_linux_x86_64.rpm-bin
    rpm -ivh TIB_sb-lvdt_1.6.2_linux_x86_64.rpm-bin

Archive Installer. To install external adapters from their archive installers into a standard StreamBase installation in `/opt/tibco/sb-cep/`n.m``, follow this example, run as root. This example presumes you placed the downloaded installer files in `/home/`sbuser`/kits`:

    cd /opt
    tar -xzf /home/sbuser/kits/streambase-*.tar.gz

## Setting Up Your Linux Environment

For all users who will run or develop with StreamBase or Live Datamart on this Linux computer, you must configure their shell initialization files such as `.bash_profile`. Follow the instructions in the Linux section of the StreamBsae-Configured Shells page.

## Making Symbolic Links for StreamBase Commands

If you installed with the RPM installation method into a standard directory, the installer already created symbolic links in `/usr/bin` for the following sets of files:

- /opt/tibco/sb-cep/`n.m`/bin/jsb*

- /opt/tibco/sb-cep/`n.m`/bin/sb*

- /opt/tibco/sb-cep/`n.m`/bin/sb*.ini

The RPM installer created links in `/usr/lib` for the following files:

- /opt/tibco/sb-cep/`n.m`/lib/*.jar

- /opt/tibco/sb-cep/`n.m`/lib64/libsb*

If you installed with the RPM installation method into a custom directory, the symbolic links are incorrect and must be removed and recreated using the path in the example, above.

If you installed with the archive installer, you can create the same links manually. These links are not strictly required to run StreamBase Server locally on this machine.

Create these links by running commands like the following as root or with sudo:

    sudo ln -s /opt/tibco/sb-cep/n.m/bin/sb*      /usr/bin/
    sudo ln -s /opt/tibco/sb-cep/n.m/bin/jsb*     /usr/bin/
    sudo ln -s /opt/tibco/sb-cep/n.m/bin/ep*      /usr/bin/
    sudo ln -s /opt/tibco/sb-cep/n.m/bin/lv-client          /usr/bin/
    sudo ln -s /opt/tibco/sb-cep/n.m/distrib/tibco/bin/ep*  /usr/bin
    sudo ln -s /opt/tibco/sb-cep/n.m/lib/*.jar    /usr/lib/
    sudo ln -s /opt/tibco/sb-cep/n.m/lib64/libsb* /usr/lib/

## Uninstalling StreamBase on Linux

To uninstall StreamBase on Linux, follow these steps:

1. Before uninstalling, prepare and save a version-specific backup copy of your current StreamBase Studio workspace on your primary development machines.

2. Log in as `root` (if you installed the product in an area that requires `root` access, such as `/opt/tibco`), or run the following commands with sudo.

3. Confirm that the StreamBase Deployment Runtime is not running on this machine with commands like the following:

       ps -A | grep -i dtmengine | grep -v grep
       ps -A | grep -i swcoord   | grep -v grep

   If the StreamBase Runtime is running, confirm that all running StreamBase nodes can be shut down without disrupting StreamBase users or applications. At the appropriate time, enter the applicable commands similar to the following.

       epadmin nodename=node.cluster stop node
       epadmin nodename=node.cluster remove node

4. Remove the StreamBase RPM packages or remove the installation directory, depending on the installation method you used.

   If you installed using the archive installer, the only step is to remove the installation directory.

       rm -rf /opt/tibco/sb-cep/n.m

   If you installed using the RPM installer, use the following instructions to uninstall:

   1. Use a command like the following to determine the StreamBase packages currently installed:

          rpm -q -a | grep -i streambase

   2. If you installed external adapters or add-in features, remove those RPM packages first, using commands like the following example:

          rpm -e streambase-flume-adapter

   3. Enter a command like the following to remove the StreamBase packages. You only need to specify the first portion of the name, up to the version string. (The command is shown broken onto several lines for clarity. Enter the command as a single unbroken line):

          rpm -e streambase-client \
                 streambase-studio streambase-server \
                 streambase-devel streambase-docs

      If you prefer to uninstall each package separately, then remove `streambase-client` last, because the other packages depend on its presence.

5. If you installed with the RPM method, or if you manually established the symbolic links in `/usr/bin` and `/usr/lib` as described in Making Symbolic Links, remove those symbolic links now. (If you are uninstalling only in order to reinstall a newer release, you can skip this step.)

## Downgrading StreamBase Versions

When you upgrade from one StreamBase release to a newer release, on first run, StreamBase Studio may automatically and silently upgrade the XML representation of your EventFlow module files.

If you need to downgrade back to a previously used StreamBase release (such as to add a feature to an existing application), the older StreamBase Studio may not recognize some of the changes made to your modules by the newer Studio.

Thus, if you find you need to return to an older StreamBase release, do so using a separate Studio workspace containing the older release's projects that you preserved or restored from backup.
