Error: ORA-01017: invalid username/password; logon denied
Recreated password file, ignorecase=Y.
See MOS Document : DATA GURAD LOG SHIPPING FAILS WITH ERROR ORA-16191 IN 11G [ID 462219.1] (this GURAD misspelling is how it displays in MOS)
ORA-16191: Primary log shipping client not logged on standby
The issue seems to be because of password mismatch between primary and standby.
The password file has to have identical authentication info for both primary and standby
If you change or create the password file using orapwd for SYS,it will not work in 11G.
Turn off the case sensitivity option by changing init.ora parameter SEC_CASE_SENSITIVE_LOGON=FALSE.
Create password files on both servers using the same password and pass ignorecase=Y to orapwd utility.
Make sure you use identical options during password file creation for both primary and standby
