System Requirements

Before installing Adaptive Server, ensure that your system is updated with the latest patches and system requirements. Do not use a patch that is earlier than the version suggested for your operating system. Use the patch recommended by the operating system vendor, even if it supersedes the patch listed.

To list all currently installed patches and display the operating system version level, enter:

lslpp -L | grep devices.fcp.disk.rte

You see:

devices.fcp.disk.rte 6.1.0.3  COMMITTED  FC SCSI CD-ROM, Disk,

Note: The Java Virtual Machine (JVM) and associated Adaptive Server support require at least 250MB of virtual memory space to start, and may need more depending on the requirements of the individual Java executions. For this reason, you may need to adjust the memory parameters when running Java to ensure that it has enough virtual memory space to start, and that both Adaptive Server and Java tasks can successfully coexist.

In particular, systems that have Adaptive Server total memory set to a value higher than 1.5GB (or 2.5GB on some Enterprise servers) may experience problems, and you may have to reduce Adaptive Server total memory.

IBM Requirements for Cluster Edition

Adaptive Server hardware and memory specifications for IBM AIX:

Processor 64-bit – Power6, Power5, Power4, and PowerPC 970
Kernel – 64-bit
Minimum RAM required for Adaptive Server – 272MB
Default user stack size – 148KB
Minimum RAM per additional user – Approximately 364kB

Operating system requirements for IBM AIX:

Hardware – IBM Power, System p, System i, System p5, System i5, eServer p5, eServer i5, eServer pSeries, and BladeCenter blades
Operating system
- AIX 6.1 runs on based on POWER4, PPC970, POWER5 and POWER6 processors.
- AIX OS IBM Power, System p, System i, System p5, System i5, eServer p5, eServer pSeries and eServer i5 servers, and BladeCenter blades.
Updates – Fileset devices.fcp.disk.rte 6.1.0.3 or higher
Preferred RAM – at least 1G

AIX 6.x and 7.x require a patch that fixes APAR IV10828, a known AIX issue. Contact IBM directly to obtain the patch.

Before you can install a 64-bit Adaptive Server version 15.7 to a Red Hat Enterprise Linux 6.x x86_64, install the 32-bit GNU C Libraries package (glibc-2.xx-x.xx.el6.i686.rpm).

Ensure that you have the required operating system patches for the Java Runtime Environment (JRE) version 6.

Information about the required operating system patches is available from the http://www.ibm.com/java .

See the Clusters Users Guide for hardware requirements for using Infiniband, Interconnect on a production system. Sybase does not support file system devices when running on multiple nodes.

If you intend to run the cluster under Symantec Storage Foundation for Sybase Cluster Edition, see Chapter 11, “Using the Cluster Edition with the Veritas Cluster Server,” in the Clusters Users Guide. Veritas Cluster Server for Sybase Cluster Edition is only supported on Solaris Sparc64 and Linux x86-64. It is not available for Solaris x86-64.

Database devices in the Cluster Edition must support SCSI-3 persistent group reservations (SCSI PGRs). Cluster Edition uses SCSI PGRs to guarantee data consistency during cluster membership changes. Sybase cannot guarantee data consistency on disk subsystems that do not support SCSI PGRs (such a configuration is supported for test and development environments that can tolerate the possibility of data corruption).
