Memory

AIX and Linux

16 MB RAM minimum required beyond the requirements of the operating system and running applications

Swap space = 2*RAM size

512 MB RAM minimum required, of which a minimum of 64 MB RAM is required beyond the requirements of the operating system and running applications for successful ContinuousDataReplicator operations; 1 GB RAM recommended

Hard Disk

CDR on Windows:

66 MB minimum of hard disk space for software

50 MB of additional hard disk space for log file growth

10 MB of temp space required for install or upgrade (where the temp folder resides)

  • 1 GB minimum of additional hard disk space on the source computer for replication log file growth; more is recommended
  • 1 GB of additional hard disk space on the destination computer for replication log file growth for each source computer (e.g., if five source computers are configured to use the same destination computer, then 5 GB of additional hard drive space is required on the destination computer)

CDR on UNIX:

250 MB minimum of hard disk space for software

  • 3 GB minimum of additional hard disk space on the source computer for replication log file growth; more is recommended. Maximum allowed is 80% of total space on the file system.
Refer to Data Replication for important considerations when allocating replication log file space.

Peripherals

DVD-ROM drive

Network Interface Card

Miscellaneous

TCP/IP Services configured on the computer.

The File System iDataAgent is not automatically installed during installation of the ContinuousDataReplicator. If you wish to install the File System iDataAgent, you must select the option to do so during installation of the ContinuousDataReplicator. For System Requirements specific to the File System iDataAgent, refer to System Requirements - Microsoft Windows File System iDataAgent.

Microsoft Visual C++ 2008 Redistributable Package is automatically installed. Note that Visual C++ 2008 Redistributable Package can co-exist with other versions of this software.

.NET Framework 2.0 is automatically installed. Note that .NET Framework 2.0 can co-exist with other versions of this software.

If you have SELinux enabled on the client computer, create the SELinux policy module as a root user before performing a backup. The SELinux Development package must be installed on the client.

To create SELinux policy module, perform the following steps as user "root":

  1. Create the following files in the /usr/share/selinux/devel directory:
File Name Content of the file
<directory>/<file_name>.te

where:

<directory> is /usr/share/selinux/devel

<file_name> is the name of the Unix file, created to save the policy module statement. It is a good idea to use the same name for policy module and the file.

For example: When you are creating a policy module for backup_IDA application, you can use the following file name: backup_IDA.te

 

 The content of the file should be as follows:

policy_module(<name>,<version>)

##############################

where:

<name> is the name of the policy module. You can give any unique name to the policy module, such as a process or application name.

<version> is the version of the policy module. It can be any number, such as 1.0.0.

For Example: While creating a policy module for the backup_IDA application, you can use the following content.

policy_module(backup_IDA,1.0.0)
<directory>/<file_name>.fc

where:

<directory> is /usr/share/selinux/devel

<file_name> is the name of the Unix file, created to save the policy module statement. It is a good idea to use the same name for policy module and the file.

For example: When you are creating a policy module for backup_IDA application, you can use the following file name: backup_IDA.fc

 

 The content of the file should be as follows:

Note that the following list of files is not exhaustive. If the process fails to launch, check /var/log/messages. Also, if required, add it to the following list of files.

/opt/<software installation directory>/Base/libCTreeWrapper.so -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libCVMAGuiImplgso -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libdb2locale.so.1 -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libdb2osse.so.1 -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libDb2Sbt.so -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libdb2trcapi.so.1 -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libDrDatabase.so -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libIndexing.so -- gen_context(system_u:object_r:texrel_shlib_t,s0)

/opt/<software installation directory>/Base/libSnooper.so -- gen_context(system_u:object_r:texrel_shlib_t,s0)

 
  1. Create the policy file from command line. Use the following command. Ensure that you give the following commands in the /usr/share/selinux/devel directory.

[root]# make backup_IDA.pp

Compiling targeted backup_IDA module

/usr/bin/checkmodule: loading policy configuration from tmp/backup_IDA.tmp

/usr/bin/checkmodule: policy configuration loaded

/usr/bin/checkmodule: writing binary representation (version 6) to tmp/backup_IDA.mod

Creating targeted backup_IDA.pp policy package

rm tmp/backup_IDA.mod tmp/backup_IDA.mod.fc

[root]# semodule -i backup_IDA.pp

[root]#

  1. Execute the policy module. Use the following command:

[root]# restorecon -R /opt/<software installation directory>

SELinux is now configured to work with this application.

Notes on Windows Installation

When installing ContinuousDataReplicator client on a Microsoft Windows x64 platform, you must install Microsoft .NET Framework 2.0.

Notes on Linux Installation

A compiled version of the CDR driver is supplied only for the listed versions and kernels. If you perform online updates of Linux, you may encounter a situation where the supplied CDR driver will not load after a reboot because the kernel has been updated to a new version.

If you are installing the software on a computer running Red Hat Linux 5 or above, the file system on the computer must be compiled as a kernel module.

For example: computers running Red Hat Linux 5 with the ext2 file system will not support the ContinuousDataReplicator software, as the ext2 file system is built into the kernel. Conversely, computers running Red Hat Linux 5 with the ext3 file system compiled as a kernel module will support the ContinuousDataReplicator software.

DISCLAIMER

Minor revisions and/or service packs that are released by application and operating system vendors may, in some cases, affect the working of our software. Although we may list such revisions and/or service packs as “supported” in our System Requirements, changes to the behavior of our software resulting from an application or operating system revision/service pack may be beyond our control. However, we will make every effort to correct such disruption as quickly as possible. When in doubt, please contact your software provider to ensure support for a specific application or operating system.

Additional considerations regarding minimum requirements and End of Life policies from application and operating system vendors are also applicable.
