System Requirements

Before installing SAP Replication 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 or check the latest release bulletin.

Item	Requirement
RAM	A minimum of 4GB RAM.
Disk storage	For a full installation, the total disk space required is approximately 2.5GB. Disk space required: 950MB for the software, supporting files, and log files on all UNIX operating systems except on IBM AIX and HP-UX Itanium that require 4GB. (Optional) A minimum of 700MB if you are installing SAP Replication Server Data Assurance (DA) Option. An additional 20MB for each SAP Replication Server disk partition. The disk partition may be on a different disk than your software. One of: Disk space for your SAP ASE database, which serves as your Replication Server System Database (RSSD) if you are not using the Embedded RSSD (ERSSD). See your Adaptive Server Enterprise documentation for system requirements. 80MB for your SAP SQL Anywhere database, which serves as your ERSSD. The database directory, transaction log directory, and backup directory that make up the 80MB should each reside on different disks. More disk space may be required, depending on your replication system application.
Operating system	One of: HP-UX Itanium II 11.31 (64-bit) The installer requires the gzip utility. Ensure that the path to gzip is set in the $PATH environment variable. IBM AIX (64-bit): AIX 6.1 AIX 7.1 Before you install SAP Replication Server, install the IBM XL C/C++ Runtime for AIX and the SMP Runtime Libraries required for your version of AIX. Obtain the libraries from your IBM AIX operating system installation media. These libraries are also available from the IBM AIX Web site: The IBM XL C/C++ Runtime for AIX is available on the Web site under “Latest updates for supported IBM C and C++ compilers.” The SMP Runtime Libraries for AIX are available on the Web site under “IBM XL C/C++ Enterprise Edition for AIX, Runtime Environment and Utilities.” To verify that the libraries are installed, issue: source $SYBASE/SYBASE.csh cd $SYBASE/$SYBASE_REP/bin ldd ./repserver Linux x86-64 (64-bit): Red Hat Enterprise Linux 5.5 kernel – 2.6.18-194.el5 #1 SMP glib – 2.5-49 Red Hat Enterprise Linux 5.6 kernel – 2.6.18-238.5.1.el5 #1 SMP glibc – 2.5 Red Hat Enterprise Linux 5.7 kernel – 2.6.18-274.el5 glibc – 2.5-49 (64-bit) Red Hat Enterprise Linux 5.8 kernel – 2.6.18-339.el5 glibc – 2.5-105 (ExpressConnect for HANA SAP HANA database) Red Hat Enterprise Linux 6 Red Hat Enterprise Linux 6.2 kernel – 2.6.32-131.0.15.el6.x86_64 #1 SMP glibc – 2.12-1.47 Red Hat Enterprise Linux 6.3 kernel – 2.6.32-220.el6.x86_64 #1 SMP glibc – 2.12-1.80 Red Hat Enterprise Linux 6.5 kernel – 2.6.32-431.el6.x86_64 #1 SMP glibc – glibc-2.12-1.132 (ExpressConnect for SAP HANA database) SuSE Linux Enterprise Server SLES 11 SuSE Linux Enterprise Server SLES 11 Service Pack 2 kernel – 3.0.13-0.27 -default #1 SMP glibc –2.11.3-17.31.1 SuSE Linux Enterprise Server SLES 11.1 kernel – 2.6.32.12-0.7-default #1 SMP glibc –2.11.1-0.17.4 Linux on IBM p-Series (Linux on POWER) (64-bit): Red Hat Enterprise Linux 5.5 kernel – 2.6.18-53.el5 #1 SMP glibc – 2.5-49 Red Hat Enterprise Linux 6.0 kernel – 2.6.32-71.el6.ppc64 #1 SMP glibc – 2.12-1.7.el6.ppc64 glibc – 2.12-1.7.el6.ppc Red Hat Enterprise Linux 6.5 kernel – 2.6.32-431.el6.ppc64 #1 SMP glibc – glibc-2.12-1.132 SuSE Linux Enterprise Server SLES 11 kernel – 2.6.27.19-5 - ppc64 #1 SMP glibc – 2.9-13.2 Note: ExpressConnect for SAP HANA database is not supported on Linux on IBM p-Series. Solaris (64-bit) Solaris 10 Solaris 11
Supported protocols	TCP/IP

Operating System Patch Level

If your operating system requires patches, install them before you install SAP Replication Server components.

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

On HP-UX, enter:
```
/usr/sbin/swlist -l patch
```
On IBM AIX, enter:
```
/usr/sbin/instfix -a
```
On Solaris, enter:
```
showrev -p
```
On Linux, enter:
```
rpm -q -a
```
Linux distributors that supply Linux Kernel version 2.4.x should provide all the libraries you require. If you are alerted to any outdated or missing libraries, download them from your Linux distributor’s Web site.
