Hi Friends,

This is my first blog in SCN.I am much interested to share my thoughts and knowledge.

Recently we have implemented NLS Solution for one of our Major Client.I am going to share the Experience.

OS Platform:SUSE Linux

Database :Sybase IQ Support Pack-08,Patch Level-10

What is meant by SYBASE IQ Server?

SAP® Sybase® IQ is a high-performance decision-support server designed specifically for mission-critical business intelligence, analytics, and data warehousing. Component Integration Services within SAP Sybase IQ provide direct access to relational and non-relational databases on mainframe, UNIX, or Windows servers.

Since we have implemented on Linux,I am concentrating on Linux:

Pre-installation Tasks:

Check for Operating System Patches.
Increase the Swap Space.
Install Required Support Packages and Libraries.
Disable HugePages and Transparent HugePages.
Set the Kernel Parameters.

Swap Space:

Asynchronous I/O (AIO) Kernal Support

Asynchronous input/output (AIO) applications which use the native AIO interfaces require the libaio package. AIO provides an interface that submits multiple I/O operations and other processing requests in a single system call, and an interface that collects completed I/O operations associated with a given completion group.

Disable HugePages and Transparent Huge Pages

Allocating large amounts of memory to HugePages can significantly degrade SAP IQ performance. If the kernel allocates more than just a few MB of memory to HugePages, remove the HugePages options

Set the Kernel Parameters

Set the number of available semaphore identifiers
SEMMSL – maximum number of semaphores per set.
SEMMNS – maximum number of semaphores system–wide.
SEMOPM – maximum number of operations allowed for one semop call.
SEMMNI – maximum number of semaphore identifiers (sets).

Supported Server Platforms

SAP IQ is compatible with these platforms and operating systems in Linux:
Red Hat Enterprise Linux 6.2 (and later) Linux on POWER; 64-bit
Red Hat Enterprise Linux 6.2 (and later) x86-64, Advanced Server and Workstation Editions
Red Hat Enterprise Linux 5.5 (and later) Linux on POWER; 64-bit
Red Hat Enterprise Linux 5.5 (and later) x86-64, Advanced Server and Workstation Editions
SuSE Linux Enterprise Server SLES 11/Linux on POWER – minimum patch level SP1
SuSE Linux Enterprise Server SLES 11/X86_64 64-bit – minimum patch level SP1

Preinstallation Tasks

Swap Space:

The recommended minimum swap space is at least 1GB. Certain operations may cause the memory usage to grow dynamically. Changing the way SAP IQ uses buffers can dramatically change the way it uses memory.
