DOCU_READ problem

hello all,

i tried installing SAP 4.7 with oracle database 8.7.1.0 and patch 8.7.1.1

installed everything successfully.. made entries in host file...

now the problem is from the SAP service... SAPPEP_00

PEP is the System ID...

when i start the win 2003 server, i get a warning message... please check one of the services has failed to start and that service is SAPPEP_00

hope this failure affects the DOCU_READ function module in the initialization of Database and finally it causes failure in the verification of hostname.

the error message displayed is DBIF_RSQL_INVALID_REQUEST

how to fix this issue?

please help..

Thank you ppl...
