Invalidating space timestamp

When the rollback segment tablespace is created using extendable files then the files can end up growing well beyond any reasonable size necessary to support the transaction load of the database.Developers are often unaware of the need to commit distributed queries and as a result often create distributed applications that cause, experience, or contribute to rollback segment related problems like ORA-01650 (unable to extend rollback). If the value of the GLOBAL_NAMES initialization parameter is TRUE, then the database link must have the same name as the database to which it connects.global_names open_links open_links_per_instance The global_name is made up of the db_name and the db_domain, and the first element (before the first .in a global name is treated as the 'db_name' and the rest of the global_name is treated as the 'db_domain'.~ Sybrand Bakkerset linesize 121 col name format a30 col value format a30 SELECT name, value FROM gv$parameter WHERE name IN ('db_name', 'db_domain'); col value$ format a40 col comment$ format a40 SELECT * FROM props$ WHERE name LIKE '%GLOBAL%'; ALTER DATABASE RENAME GLOBAL_NAME TO orabase.psoug.org; SELECT * FROM props$ WHERE name LIKE '%GLOBAL%'; 'conn_link'; desc user_db_links set linesize 121 col db_link format a20 col username format a20 col password format a20 col host format a20 SELECT * FROM user_db_links; SELECT * FROM all_db_links; SELECT table_name, tablespace_name FROM [email protected]_user; 'conn_link'; desc user_db_links set linesize 121 col db_link format a20 col username format a20 col password format a20 col host format a20 SELECT * FROM user_db_links; SELECT * FROM all_db_links; SELECT table_name, tablespace_name FROM [email protected]_user; BY hr USING 'conn_link'; SELECT * FROM all_db_links; desc gv$session_connect_info set linesize 121 set pagesize 60 col authentication_type format a10 col osuser format a25 col network_service_banner format a50 word wrap SELECT DISTINCT sid FROM gv$mystat; SELECT authentication_type, osuser, network_service_banner FROM gv$session_connect_info WHERE sid = 143; SELECT table_name, tablespace_name FROM [email protected]_user; 'conn_link'; SELECT * FROM dba_db_links; conn scott/tiger SELECT table_name, tablespace_name FROM [email protected]; conn sh/sh SELECT table_name, tablespace_name FROM [email protected]; conn uwclass/uwclass SELECT table_name, tablespace_name FROM [email protected];set linesize 121 col db_link format a45 col username format a15 col password format a15 col host format a15 SELECT db_link, username, password, host, created FROM user_db_links; conn / as sysdba desc link$ col name format a20 col authpwdx format a40 SELECT name, userid, authpwdx FROM link$; BEGIN ALTER SESSION CLOSE DATABASE LINK remove_db; SELECT table_name INTO i FROM [email protected]_db WHERE rownum = 1; EXCEPTION WHEN OTHERS THEN RAISE_APPLICATION_ERROR(-20999, 'No Connection'); END; Why does it seem that a SELECT over a db_link requires a commit after execution ? When Oracle performs a distributed SQL statement Oracle reserves an entry in the rollback segment area for the two-phase commit processing.By clicking “Sign up for Git Hub”, you agree to our terms of service and privacy statement.
