SAP NW 7.4 SR1 installtion on Hana

Hi,

We planned to install SAP NW 7.4 on SAP hana in distribute landscape.

1. i installed ASCS instance and planning to install Hana DB instance.

is there any pre-reqisites to install Hana DB instance. (ex: Hana DB software installation as oracle)

when i proceed with DB instance installation, i'm facing below error

com.sap.hdb.sl.lib.user.password.HdbPassword | Error retrieving password policy from database: com.sap.db.jdbc.exceptions.JDBCDriverException: SAP DBTech JDBC: Cannot

connect to jdbc:sap://host :30015 [Cannot connect to host localhost:30015 [Connection refused], -813.].. Using default values

Regards,

Siva
