Troubleshooting guide

• You are familiar with DB2 UDB and SAP HANA database.
• You have valid licenses for Replication Server with ExpressConnect for HANA DB and
Replication Server Options.
• DB2 UDB 9.5 or 9.7 is installed and configured to serve as the source (primary) database
from which Replication Agent replicates transactions, and SAP HANA database is
installed and configured as the target (replicate) database to which Replication Server with
ExpressConnect for HANA DB replicates transactions.
• TCP/IP connectivity is available between all hosts.
• Any operating system patches required for Java have been installed.
Do not use Replication Server reserved words for object names or connection names. A
complete list of reserved words is in the Replication Server Reference Manual .
Planning Your Installation
Before installing the replication components, verify the system requirements, identify the
Sybase installation directories, and obtain the installation software.
System Requirements
Make sure the target computer on which you are installing the replication components meets
the minimum memory and disk space requirements.
See the
Replication Server Installation Guide > Planning Your Installation > System
Requirements and the Replication Agent Installation Guide > Planning Your Installation >
System Requirements .
To improve performance by avoiding multiple network hops, install Replication Server and
the SAP HANA database on the same machine.
Note: The only versions of Linux that ExpressConnect for HANA DB supports are Red Hat
Enterprise Linux 6 and SuSE Linux Enterprise Server (SLES) 11.
Identify the Sybase Installation Directory
Determine the directory in which to install the replication components.
Replication Agent, Replication Server, and ExpressConnect for HANA DB are installed in the
same base directory, which is identified by the SYBASE environment variable. Select a path
on the host drive to be the recipient of the Sybase installation and configuration activities.
Replication Agent must be installed on the same host as either the DB2 UDB server or the DB2
Administration Client.
