Requirements of Supported Applications and Databases › Microsoft SQL Server Replication and High Availability › High Availability for SQL Server › SQL Servers Operating in a Workgroup

SQL Servers Operating in a Workgroup

For servers in a workgroup, set the CA ARCserve HA Engine service account to a user that is a member of the Local Administrators group. Servers in a workgroup can use Redirect DNS only with DNS servers that allow non-secure updates. You can use Move IP, Switch Computer Name, and custom redirection scripts normally.

When Switch Computer Name is used, you may use the System Account or the Local Administrators group as long as the account was added to the Microsoft SQL logins.

SQL HA Clusters

To install on a cluster, enter the SQL Server's Virtual Server Name as the Master or Replica name.

The only configuration that requires some preparation is the use of IP Move in conjunction with a cluster. For detailed instructions on how to use Move IP with clusters, see the CA ARCserve RHA Microsoft SQL Operation Guide.

IIS Server High Availability

This section describes the requirements for running CA ARCserve HA for Microsoft IIS server.

IIS HA Configurations

To implement High Availability procedures using CA ARCserve HA IIS server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

  • Both servers should have the same level of service packs and hot fixes installed.
  • (In the Active Directory environment) Both Master and Replica servers should reside in the same Active Directory forest and be members of the same domain or trusted domains.
• An instance of Microsoft IIS Server 6.0 or 7.0/7.5 installed on each server:
  • Both servers should have the same IIS services installed: WWW, SMTP, etc.
  • Both servers should have identical web service extensions installed.
  • Full paths containing site files should be identical on both servers.
• The standby server should hold a clean installation of IIS with the default sites only.
• Sites on the Master server should not use URL redirection or UNC path redirection.
• If anonymous access is enabled and used, configure the following:

  In order to keep permissions synchronized between the two servers, both IIS processes should use the same user account for anonymous user access. Create a new Domain user account and configure both IIS servers to use it. The following documents describe how to do this:

  • For IIS 6.0: How To Configure IIS Web Site Authentication in Windows Server 2003 http://support.microsoft.com/kb/324274
  • For IIS 7.0/7.5: Configure the Anonymous Authentication Identity http://technet.microsoft.com/en-us/library/cc770966

    Note: Although the documents do not specify it, you need to edit the Local (or Domain) group policy to allow the user account the following privileges: Allow log on locally, Allow log on as a batch job, and Access this computer from the network. Also, make sure to duplicate any permission changes made to the file system for the original anonymous user account to the newly assigned domain account as well.

• In IIS 6.0 and 7.0/7.5, if you define any new application pools on the Master server, you should also define them on the Replica server.
• If you are using SSL encryption, see the following MS documents concerning copying the proper certificate:
  • For IIS 6.0: How to load balance a Web server farm by using one SSL certificate in Internet Information Services version 6.0 in http://support.microsoft.com/kb/313299
  • For IIS 7.0/7.5: Setting Up IIS 7.0 in http://technet.microsoft.com/en-us/library/cc268245.aspx
• The protected server is not a domain controller or DNS server.
• If you are using IIS 7.0/7.5, you need to have IIS 6.0 Management Compatibility installed. Since the IIS 6.0 Management Compatibility is disabled by default when installing IIS 7.0/7.5, you need to enable this option during the IIS 7.0/7.5 installation process.

IIS HA Log On Account

The CA ARCserve HA Engine service log on account must satisfy all of the following account conditions:

• It is a member of the Domain Admins group. If the Domain Admins group is not a member of the built-in domain local group Administrators you must use an account that is.
• It is a member of the local machine Administrators Group. If the Domain Admins group is not a member, add the account manually.
• For servers in a work group, use the Local System account.

Note: If your company's security policy requires more granular permissions than described, contact technical support to receive detailed instructions. Special considerations apply to IIS servers operating workgroups: see the Operation Guide for more information.

Oracle Server High Availability

This section describes the requirements for running CA ARCserve HA for Oracle Server.

Oracle HA Configurations

To implement High Availability procedures using CA ARCserve HA Oracle Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

  • Both servers should have the same level of service packs and hot fixes installed.
• Both servers should have the same Oracle version, service packs and hot fixes installed.
• (In the Active Directory environment) Both Master and Replica servers should reside in the same Active Directory forest and be members of the same domain or trusted domains.
• The Oracle SID must match between the Master and Replica servers.
• On both servers, ensure that all Oracle Services normally started at boot have been successfully started and are set to Automatic Startup.
• The path to ORACLE_HOME directory and the path to the database files on the Master and Replica servers must be identical.
• To minimize replication traffic, Oracle temporary tablespace(s) are excluded from replication (make sure that the Oracle database on the Replica server is configured with the same temporary tablespace names and path as is used on the Master server).
• On both servers, configure Oracle to mount the database automatically on service startup (oradim -edit -sid ORACLE_SID -startmode auto).
• The protected server is not a domain controller or DNS server.

On UNIX/Linux systems, CA ARCserve RHA requires the 32-bit Oracle Instant Client to support Oracle databases. If you do not already have this client installed, abort CA ARCserve RHA installation, download the Oracle Instant Client from the Oracle website and restart CA ARCserve RHA installation. If the instant client is already installed, you must manually provide the full installation path.

Oracle HA Log On Account

The CA ARCserve HA Engine service log on account must satisfy all of the following conditions:

• It is a member of the Domain Admins group. If the Domain Admins group is not a member of the built-in domain local group Administrators you must use an account that is.
• It is a member of the local machine Administrators Group. If the Domain Admins group is not a member, add the account manually.

Note: If your company's security policy requires more granular permissions than described, contact technical support to receive detailed instructions.

Oracle Servers Operating in a Workgroup

For servers in a workgroup, set the Engine service account to a user that is a member of the Local Administrators group. Servers in a workgroup can use Redirect DNS only with DNS servers that allow non-secure updates. You can use Move IP, Switch Computer Name, and custom redirection scripts normally.

Microsoft Hyper-V Server Replication and High Availability

Hyper-V Server Replication

This section describes the requirements for running CA ARCserve RHA for Hyper-V Server.

Hyper-V Replication Configuration

To implement Replication for Hyper-V Server, you need to have the following configurations:

• The Master running on Windows Server.
• The Replica running on Windows Server.
• An instance of Hyper-V Server installed on the Master.

Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

Hyper-V Replication Log On Account

The CA ARCserve RHA Engine service log on account must meet all of the following conditions:

• For stand-alone servers (i.e., non-clustered), use the default of Local System.
• For cluster nodes, use a service account that is a Local Administrator on all cluster nodes.

High Availability for Hyper-V

This section describes the requirements for running CA ARCserve HA for Hyper-V Server.

Hyper-V HA Configuration

To implement High Availability procedures for Hyper-V Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• Both servers should have the same Hyper-V version, service packs and hot fixes installed.
• (In the Active Directory environment) Both Master and Replica servers should reside in the same Active Directory forest and be members of the same domain or trusted domains.
• Statically assign all IP addresses (DHCP-assigned IP addresses on the Master or Replica server are not supported).
• The protected server is not a domain controller or DNS server.

Do not use the default Hyper-V installation path. Instead, create a new folder, such as c:\vm\ on both Master and Replica. CA ARCserve RHA cannot access the default virtual machine installation path during auto-discovery.

Hyper-V HA Log On Account

The CA ARCserve HA Engine service log on account must satisfy all of the following account conditions:

• It is a member of the Domain Admins group. If the Domain Admins group is not a member of the built-in domain local group Administrators you must use an account that is.

This section describes the requirements for running CA ARCserve HA for SharePoint Server.

SharePoint HA Configuration

To implement High Availability procedures for SharePoint Server, you need to have the following configurations:

• Two servers running supported Windows Server with the same level of service packs and hot fixes installed.

  Note: For a complete list of supported operating systems and applications, see the CA ARCserve RHA Release Notes.

• An instance of a SharePoint Server installed on each server:
  • Both servers should have the same identical service packs and hot fixes.
  • Both servers should reside in the same Active Directory forest, and be members of the same domain or trusted domains.
  • Both servers should use the same port.
  • Both servers should have the same SQL version, service packs, and hot fixes installed.
  • Both servers should hold identical SQL Server instances, i.e., default or named.
  • Drive letters containing database files should be identical on both servers.
  • The full path to the default system database of each instance should be identical on both servers.
• If you are installing SharePoint with SQL Server Express Edition, you must enable TCP/IP protocol for that SQL instance (i.e. OfficeServers) on both Master and Replica servers.
• Verify that the port defined in the Network Configuration TCP/IP properties of the SQL instance(s) is assigned statically and is identical on both Master and Replica.
• No participating server can be a domain controller or DNS server.
• Master and Replica servers must reside in the same Active Directory forest.

SharePoint HA Log On Account

The CA ARCserve HA Engine service log on account must satisfy all of the following conditions:

• It is a member of the Domain Admins group. If the Domain Admins group is not a member of the built-in domain local group Administrators, you must use an account that is.
• It is a member of the local machine Administrators Group. If the Domain Admins group is not a member, add the account manually.
• If the account does not have built-in Administrator permissions on all SQL Server instances, add appropriate permissions.

  Notes:

  • You should not use a Network Service account. This may prevent the services from functioning properly after a switchover.
  • If your company's security policy requires more granular permissions than described, contact technical support to receive detailed instructions. For servers in a workgroup, leave the log on user as Local System.
