IBM Operations Analytics - Log Analysis, Version 1.3.0

Installing on Linux on System z and Linux on System x based servers

Before you can install IBM® Operations Analytics - Log Analysis on a Linux on System z® or Linux on System x® based operating system, read and complete the prerequisites.

Hardware requirements

Linux on System z runs on System z based hardware. Linux on System x runs on Intel or AMD-based hardware. Both types of hardware are supported but there are some minor differences in the software requirements.

Note: If you install IBM Operations Analytics - Log Analysis on Intel or AMD-based hardware, you must install IBM Operations Analytics - Log Analysis components like the Indexing Engine server on Intel or AMD-based hardware. You cannot install IBM Operations Analytics - Log Analysis components on Linux on System z based hardware. Likewise, if you install IBM Operations Analytics - Log Analysis on Linux on System z based hardware, you must install IBM Operations Analytics - Log Analysis components like the Indexing Engine server on System z based hardware.

For more information about the hardware requirements, see Hardware and software requirements.

Supported operating systems for cross-platform data ingestion

You can choose one of the following methods for loading data into IBM Operations Analytics - Log Analysis:

Using the internal IBM Tivoli® Monitoring Log File Agent that is bundled with IBM Operations Analytics - Log Analysis to stream data.
Using an external IBM Tivoli Monitoring Log File Agent which you install separately to stream data.
Using the z/OS® Log Forwarder that is bundled with the z/OS Insight Packs.
Using the data collector client or FTP to load a batch of data.

Each of these scenarios offers varying cross-platform support as outlined in the following table:

Table 1. Supported operating systems for data loading scenarios
Data loading scenario	Supported operating systems
1	See the Supported Operating Systems section in Loading and streaming data
2	See the Requirements for the monitoring agent topic documentation for your version of IBM Tivoli Monitoring at:https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Tivoli%20Documentation%20Central/page/Tivoli%20Monitoring
3	See the System requirements for the z/OS Log Forwarder topic in the product documentation that is linked in the Insight Packs section
4	See the Supported Operating Systems section in Loading and streaming data

Note:

The remote installer that you use to install instances of the IBM Tivoli Monitoring Log File Agent and the Tivoli Event Integration Facility does not support cross operating system integration. You must use the remote installers to install remote instances on servers that use the same operating system. For example, if you install IBM Operations Analytics - Log Analysis on Linux on System z, you must install the remote instances on Linux on System z. In this example, you cannot install remote instances on Linux on System x.

Insight Packs for z/OS

You can install Insight Packs for z/OS SYSLOG and WebSphere® Application Server for z/OS separately on both Linux on System z and Linux on System x based servers. For more information, see:

Linux on System z logstash support

logstash 1.2.2 is bundled with the IBM Operations Analytics - Log Analysis Linux on System z 64-bit installation package. However, logstash cannot be deployed on Linux on System z, except for log aggregation on Linux x86 based hardware.

Installing on non-English-language systems

If you want to install IBM Operations Analytics - Log Analysis on a system where the locale is not set to English United States, you need to set the locale of the command shell to export LANG=en_US.UTF-8 before you run any IBM Operations Analytics - Log Analysis scripts. For example, when you install IBM Operations Analytics - Log Analysis you need to run the following command to change the locale before you run the unity.sh script:

export LANG=en_US.UTF-8

Tuning the operating system

To tune the Linux operating system, ensure that the following resource configuration settings are made:

Number of concurrent files: 4096: Use the ulimit -n command to change this setting to 4096.
Virtual memory: Unlimited: Use the ulimit -v command to change this setting to unlimited.
