1.0 Welcome

Welcome to the BrightStor^® ARCserve^® Backup r11.5 Client Agent for OpenVMS. The agent is installed on network client machines to act as a remote agent for cross platform backup and restore support. The agent uses TCP/IP to communicate with the BrightStor ARCserve Backup server. This readme file provides you with the basic information you need to install and use the Client Agent for OpenVMS .

2.0 Supported Platforms

The Client Agent for OpenVMS supports the following platforms:

• VAX 6.2, 7.1, 7.2, 7.3

• ALPHA 6.2, 7.1, 7.2, 7.3, 8.2

2.1 Supported TCPIP Stacks

The Client Agent for OpenVMS supports, at minimum, the following TCPIP stacks:

• Compaq UCX 4.2 eco 3 (on Alpha)

• Compaq UCX 3.3 eco 13 (on VAX)

• Compaq TCPIP v5.0

• Process Software Multinet v4.1B (with patches)

• Process Software TCPWARE 5.3

3.0 Installing the Agent for OpenVMS

Before installing the agent, we recommend that you review the information in the Client Agents Guide.

To install the agent, perform the following procedure:

1. Mount the cd as follows:

   mount /over=id <cddevice:>
   

2. From a location containing at least 10 blocks, execute the following command:

   run cddevice:[openvms]bab_YYDDMM_SETUP_xxx.exe
   

   where xxx is one of the following:

   • ALPHA for alpha

   • VAX for vax

   The BAB_YYDDMM_SETUP_XXX.EXE file extracts a setup.com file and executes it.

3. You are prompted to identify a temporary area with at least 85000 blocks. The archive containing the save sets to be installed is decompressed into this area. If the location you specify does not have the required amount of disk space, you are prompted to specify a different location.

4. When the save sets have been decompressed, vmsinstal runs automatically. Follow the prompts. When installing the agent, see the Client Agents Guide for more information.

5. When the installation is complete, the agent starts automatically.

4.0 Upgrading the Agent

The Agent for OpenVMS does not have a mechanism for upgrading from an old version to a new version. You need to reinstall the Agent with the new version.

To upgrade the agent, perform the following procedure:

1. Please stop the agent, if it is running, using the following command:

   @SYS$STARTUP:BAB$SHUTDOWN
   

2. Mount the cd as follows:

   mount /over=id <cddevice:>
   

3. From a location containing at least 10 blocks, execute the following command:

   run cddevice:[VMS]BAB_YYDDMM_SETUP_XXX.exe
   

   where xxx is one of the following:

   • ALPHA for alpha

   • VAX for vax

   The BAB_YYDDMM_SETUP_XXX.EXE file extracts a setup.com file and executes it.

4. You are prompted to identify a temporary area with at least 85000 blocks. The archive containing the save sets to be installed is decompressed into this area. If the location you specify does not have the required amount of disk space, you are prompted to specify a different location. The upgrade procedure will empty out the area, used for decompressing the save sets, at the end of the upgrade procedure.

5. When the save sets have been decompressed, vmsinstal runs automatically. Follow the prompts. At one point install procedure will prompt with the following message:

   ***** This version is already installed *****

   Do you want to continue? [Y]?

   Please respond with 'Y' to continue with upgrading the agent to the latest version.

6. When the upgrade is complete, the agent starts automatically.

5.0 Configuring Compaq/UCX OpenVMS TCP/IP Services

If performance is slow using the default stack configuration, set the send and receive quotas to the maximum. The following sections provide information to help you change these values.

5.1 DEC TCP/IP Services

If you are using the DEC TCP/IP Services V4.2 (with ECO), also known as UCX, enter the following command at the DCL prompt to view the current settings:

$ UCX SHOW PROTOCOL TCP /PARAM

The output you receive is similar to the following:

TCP
   MTU size segment:   disabled
   Delay ACK:          enabled
   Loopback:           disabled
   Window scale:       enabled
   Drop timer:     600
   Probe timer:        75
                   Receive Send
   Checksum:           enabled enabled
   Push:           disabled    disabled
   Quota:          4096        4096

To change the values, enter the following command at the command prompt:

$ UCX SET PROTOCOL TCP /QUOTA=RECEIVE:65000 /QUOTA=SEND:65000

6.0 Compaq TCP/IP Services

If you are running, at minimum, Compaq TCP/IP Services version 5.0, enter the following command at the DCL prompt to view the current settings:

$ TCPIP SHOW PROTOCOL TCP /PARAM

The output you receive is similar to the following:

TCP
   Delay ACK:          disabled
   Window scale:       enabled
   Drop count:     8
   Probe timer:        150
                   Receive Send
   Push:           disabled    disabled
   Quota:          4096        4096

To change these values, enter the following command at the command prompt:

$ TCPIP SET PROTOCOL TCP /QUOTA=RECEIVE:65000 /QUOTA=SEND:65000

7.0 Controlling the Agent

The Client Agent for OpenVMS supports the following features:

• Backup: The agent can perform complete disk backups (we do not recommend that you back up system disks) and combinations of disks, directories, and individual files.

9.0 Known Issues

The following issues related to the Client Agent for OpenVMS are known to exist in this release:

• The agent does not support Synonyms or Aliases

• The agent does not support backup or restore filters

• Backup jobs cannot be stopped before they finish. To stop a backup job, shut down the agent process on the OpenVMS computer. The agent job is then stopped at the host.
