tworzymy nowego tbs-a:

CREATE TEMPORARY TABLESPACE TEMP2 TEMPFILE '/data/temp201.dbf’ SIZE 100M AUTOEXTEND ON NEXT 100M MAXSIZE 65500M TABLESPACE GROUP ” EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1M;

ustawiamy jako defaulta:

ALTER DATABASE DEFAULT TEMPORARY TABLESPACE TEMP2;

ubijamy sesje, które mają dane jeszcze w temp (ew. restart DB) i dopiero wtedy można zdropować starego temp-a

SELECT b.tablespace,b.segfile#,b.segblk#,b.blocks,a.sid,a.serial#,
a.username,a.osuser, a.status, 'ALTER SYSTEM KILL

SRL log 1 needs clearing because log has not been created

Opublikowano przez Wiech

Po aplikowaniu incrementala (DG move forward: https://ora-600.com/2021/03/err-replikacji-danych-data-guard-move-forward-czyli-aplikowanie-intrementala/) możemy trafić na:

SRL log 1 needs clearing because log has not been created
SRL log 2 needs clearing because log has not been created
SRL log 3 needs clearing because log has not been created
SRL log 4 needs clearing because log has not been created

Zatrzymujemy aplikowanie archow, czyścimy grupy logów i odpalamy:

alter database recover managed standby database cancel;
alter database clear logfile group 1;
alter database clear logfile group 2;
alter database clear logfile group 3;
