HP P9000 Replication Manager Software 7.2 Configuration Guide

Exchange Management Tool
The same version of Exchange Management Tool must be installed on the database and backup
servers.
ESEUTIL and Exchange Server 2003
To back up an Exchange database, the Exchange management tools must be installed on both the
database server and the backup server. For Exchange Server 2003, the ESEUTIL command must
also be installed. The ESEUTIL command does not need to be installed for any other versions of
Exchange Server.
The ESEUTIL command must be copied into the Application Agent installation folder. Copy the
following files from Exchange-installation-directory\bin to
Application-Agent-installation-directory\DRM\bin\util:
• ESE.dll
• ESEUTIL.exe
• EXCHMEM.dll
• EXOSAL.dll
TIP:
It is not necessary to perform this operation if you are using Exchange Server 2007 or later.
Environment variables
Do not specify HORCMINST or HORCC_MRCF in a system environment variable. Also, do not specify
HORCM_CONF or HORCMPERM in a system environment variable or a user environment variable.
Application Agent versions on database and backup servers
The same version of Application Agent must be installed on database and backup server pairs. Do
not, for example, install version 6.3 on the database server and 6.4 on the corresponding backup
server.
Remote copy type support
Microsoft Exchange Server uses VSS to create replicas. Because VSS only supports Cnt Ac-S for remote
copies, Replication Manager must use Cnt Ac-S to create remote replicas. (Cnt Ac-A and Cnt Ac-J
remote replicas are not supported. VSS does not allow the split time to exceed 10 seconds, and these
copy types cannot meet this requirement.)
Because Microsoft SQL Server does not use VSS (it uses VDI), there is no limitation on the remote copy
type for linkage with Microsoft SQL Server. Cnt Ac-S, Cnt Ac-A, and Cnt Ac-J are also supported.
Replica operations between storage systems
Application Agent is compatible with Continuous Access Synchronous and Continuous Access Journal
backups to (and restorations from) remote site storage systems, for when a failure occurs on a local
site storage system. Depending on the DBMS product linked to, different volume replication functions
can be used:
• Exchange Server: Continuous Access Synchronous
• SQL Server: Continuous Access Synchronous and Continuous Access Journal
