Using SQL Developer 18.1 and a connection that used to work is not working any more. The Oracle DB has had MVDC added to it. I'm getting this error when I Load the LDAP definitions and choose mine:
"An error was encountered performing the requested operation: IO Error: The Network Adapter could not establish the connection"
The LDAP connect string has:
(DESCRIPTION=(CONNECT_TIMEOUT=5)(TRANSPORT_CONNECT_TIMEOUT=3)(RETRY_COUNT=1)(ADDRESS_LIST=(LOAD_BALANCE=ON)(FAILOVER=ON)(ADDRESS=(PROTOCOL=TCP)(HOST=scan-prd-001)(PORT=1541))(ADDRESS=(PROTOCOL=TCP)(HOST=scan-prd-002)(PORT=1541)))(CONNECT_DATA=(SERVICE_NAME=SVRPRD)(SERVER=DEDICATED)))
scan-prd-072 should work with service_name=SVRPRD
scan-prd-073 should work with service_name=SVRPRD_RO
The Connection Details in SQL Developer says:
RO_USER@//scan-prd-001:1541/SVRPRD
But it fails.
But if I do a basic connection to scan-prd-001 on port 1541 with service-name=SVRPRD it works.
This problem appears to be limited to SQL Developer.
