LifeKeeper Single Server Protection Product Description

LifeKeeper Single Server Protection allows for application monitoring in a single node configuration (i.e., no cluster requirements or restraints). Single node environments may be physical or virtual. LifeKeeper Single Server Protection is built on the proven and stable architecture of SIOS LifeKeeper. LifeKeeper Single Server Protection for Windows provides superior application monitoring and can perform recovery of failed applications and system infrastructure items (e.g., IP address, File Share List). If an application cannot be recovered for some reason, LifeKeeper Single Server Protection will initiate a restart of the node via a system reboot or via a VMware HA restart for VMware virtual machines configured for VM and Application Monitoring.

While installing LifeKeeper Single Server Protection for Windows 2008 R2, a dialog box will prompt whether the installer should make the system configuration changes described below. If the installer is not allowed to make these changes, they will need to be made manually after installation is complete.

  • Windows Firewall
  • The Distributed Link Tracking Client must be disabled

For systems running LifeKeeper Single Server Protection for Windows and Microsoft FTP Service 7.5 for IIS 7.0, Windows 2008 R2 or later is required.

In addition, if your Windows servers are not in a domain, the Local Security policy setting “Network Access: Let Everyone permissions apply to anonymous users” must be enabled. If the servers are in a domain, then this setting is not required.

LifeKeeper Single Server Protection for Windows Requirements

The following table shows requirements applicable to the LifeKeeper Single Server Protection for Windows and recovery kits.

LifeKeeper Single Server Protection for Windows License One license is required for every server on which LifeKeeper Single Server Protection for Windows runs. This applies to both physical and virtual servers.
LAN Manager Recovery Kit Requires the “File and Print Sharing for Microsoft Networks” component (lanmanserver) to be installed on the Windows server. NetBIOS must also be enabled. Otherwise, the LAN Manager resource will not come in service.
Memory Requirements The minimum memory requirement for a system supporting LifeKeeper Single Server Protection for Windows is based on the memory requirements for the operating system being used. Additional memory is required to run user applications in addition to that required for LifeKeeper Single Server Protection for Windows.
GUI Ports:

LifeKeeper Single Server Protection for Windows uses Port 82 for Remote Method Invocation (RMI) communication between the GUI server and client.

The LifeKeeper GUI uses Port 81 for its administration web server which should be different from any public web server. This is used by the GUI when run as a Java applet on a remote client.

In the event of conflict with an existing application, these ports can be changed by editing the RMI_PORT or WEB_PORT entries in the SIOS\LIFEKEEPER\JAVAGUI\SERVER registry key.

Client Platforms and Browsers

The LifeKeeper Single Server Protection web client can run on any platform that provides support for Java Runtime Environment JRE8 update 51. The currently supported configurations are Firefox (Firefox 51 or earler) and Internet Explorer on windows, Windows Server 2008 R2, Windows Server 2012 R2, Windows Server 2016, Windows 7, Windows 8 or Windows 10 with JRE8 update 51. Other recent platforms and browsers will likely work with the SPS web client, but they have not been tested by SIOS Technology Corp. In addition, particular features of each browser also have not been tested.

IP addresses for LifeKeeper Single Server Protection components (e.g. the SteelEye Management Console and vCenter when installed in a VMware configuration) and protected windows guests must be resolvable via DNS or the local hosts file (usually/etc/hosts or C:\windows\system32\drivers\etc\hosts). Using the local hosts file minimizes the client connection time and allows the client to connect even in the event of a Domain Name Server (DNS) failure.

Known Issue

SIOS AppKeeper

Because SIOS LifeKeeper monitors and remediates OS and application services in clustered environments in AWS EC2, the use of SIOS AppKeeper in addition to SIOS LifeKeeper in those environments is not recommended or supported.
