Adapter Engine Cache Issue

Hello All,

In SXMB_MONI i got an error saying

SAP:AdditionalText>Error while writing to secure store: ERROR_UNKNOWN: Error when updating buffer for Adapter Engine</SAP:AdditionalText>

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack>Error while reading access data (URL, user, password) for the Adapter Engine</SAP:Stack>

My Analysis :

1, In SXI_CACHE i could see 'Unable to refresh cache contents' and 'Error during last attempt to refresh cache' also I could not see any entry in Adapter Engine Connection Data Cache.

2, when execute the RFC connection 'INTEGRATION_DIRECTORY_HMI' Its asking for userId and password .

3, I tried reset the password and do a JAVA restart again with same error.

Clarificaiton need :

1 Looks some authorization error , but where exactly to maintain this ,

2, How the adatper engince connection data will populate in to sxi_cache transaction.

could you guide me clearly for this issue.
