Installation problems in MSCS ORACLE 10.2 ECC 6.00

I am writing to report some unexpected installation problems. I am installing SAP ECC 6.00 in a MSCS cluster environment (Windows 2003 / Oracle 10.2) in our production environment and I am having problems during the installing the central instance phase. The sapinst_dev shows the following error: “CJS-30102 Checking the database for installation type failed”, Also the jsourcecheck.log shows the following error: “com. sap. engine. frame. core. configuration. Configuration Exception: Error while connecting to DB” and “java. sql. SQLException: Excepci├│n de E/S: The Network Adapter could not establish the connection at oracle. jdbc.driver. DatabaseError. throwSqlException (”

The database is currently running without any problem and all the services (SAP and Oracle) as well.

Following the installation guide, I performed the almost all the steps successfully:

• Oracle RDBMS, patches and Oracle fail safe software on both nodes (successfully)

• Install the central services instance for ABAP (ASCS) on the first MSCS node (successfully)

• Install the central services instance (SCS) on the first MSCS node (successfully)

• Cluster the first MSCS node (successfully)

• Install the database instance on the first MSCS node (successfully)

• Cluster the additional MSCS node (successfully)

• Install an enqueue replication server(successfully)

• Perform additional steps for the Oracle Fail Safe configuration (successfully)

• Create the Oracle Fail Safe group (successfully)

• Set up as shared database directory in your Oracle Home (successfully)

• Add the Oracle database resource to the Fail Safe group (successfully)

• install the central instance (Failed)

• install at least one dialog instance (not installed yet)

As you can observe, I have performed the create oracle fail safe group activity first and then the install the central instance later. Reading the sap note 967121 today, I just realized that there is a wrong installation sequence; the sap note 967121 (actualized date: 17/OCT/07 ) says that “you must install the central instance before you create the Oracle Fail Safe group”. Is this sequence compulsory? Or can I continue the installation process?

If this sequence is compulsory do I have to reinstall all the predecessor activities or should I undo just the create oracle fail safe group activity?

Please let me know if the error which is showed in the installation of the central instance phase is because the wrong sequence or it is due to another reason.

Our cluster configuration is:

4 network card

Public network cards:

Ip: (hostname: ccaribe3rp1, Node A)

Ip: (hostname: ccariber3p2, node B)

Private network cards:

Ip: (hostname:, node A

Ip: (hostname:, node B


Cluster group name: SAPPRO

Cluster group Virtual IP:, network name: SAPPRO (subnet mask

SAP cluster group:

Sap clustergroup virtual IP:, network name: sapgrp (subnet mask

Database cluster group:

Database cluster group virtual Ip:, network name: dbgrp (subnet mask:

We have performed the mapping of the host names to the IP addresses on the windows host file already.

I would be very grateful if someone kindly can help me to solve this problem.

Best Regards

Boris Romero
