ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

_id col esc ddr system rip sys ESS select

在主庫查詢 SELECT DEST_ID,ERROR FROM V$ARCHIVE_DEST where rownum<3; 報錯如下: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor 解決辦法: alter system set local_listener=‘(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.56.56)(PORT=1521))‘ scope=both;

ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
