RE: switch logfile vs. archive log current

Hello Peter,

If you are going to backup the archive logs, I would recommend '.. archive log current;' because it ensures that the current logfile gets archived first before you do the backup. The problem with the other command is it will switch but Oracle may not archive the file immediately. Faced this problem with RMAN.

In my hot backup script, should I be using "alter system archive log current;"
instead of "alter system switch logfile;"?

At present this is what I am doing:

For each tablespace:

sqlplus internal << EOF
alter tablespace ERGO_USR begin backup;
exit
EOF
#

cp $DIR3/ERGO_USR.dbf $BACKUP_DIR$DIR3
#

sqlplus internal << EOF
alter tablespace ERGO_USR end backup;
alter system switch logfile;
exit
EOF For the last tablespace:

sqlplus internal << EOF
alter tablespace USERS begin backup;
exit
EOF
#

cp $DIR1/users01.dbf $BACKUP_DIR$DIR1
#

sqlplus internal << EOF
alter tablespace USERS end backup;
alter database backup controlfile to '$BACKUP_DIR$DIR1/control01.bak'; alter system switch logfile;
exit
EOF
#

Thanks,
