Criar o diretório do backup via expdp com o usuário do backup
export ORACLE_SID= <instance_name> sqlplus /nolog connect / as sysdba create or replace directory EXP_DIR_FULL as '/bkp_servidor/<instance_name>/'; grant read on directory EXP_DIR_FULL to backup; grant write on directory EXP_DIR_FULL to backup; exit
criar o parfile
usando parfile ficar escondido o usuário e a senha
cat <instance_name>.par ================= userid=BACKUP/<senha> directory=exp_dir_full FLASHBACK_TIME="TO_TIMESTAMP(TO_CHAR(SYSDATE,'YYYY-MM-DD HH24:MI:SS'),'YYYY-MM-DD HH24:MI:SS')" PARALLEL=4 expdp parfile=<instance_name>.par full=Y dumpfile=<instance_name>%u.dmp logfile=<instance_name>.log
Podemos querer voltar um backup …temos que criar imp_dir que poderá ou não ser igual ao exp_dir
export ORACLE_SID=<instance_name> sqlplus /nolog connect / as sysdba create or replace directory imp_DIR as '/bkp_servidor/<instance_name>/'; grant read on directory imp_dir to backup; grant write on directory imp_dir to backup; exit
Obs. Eu nunca uso @base, fica mais lento porque usa a rede.
setar ORACLE_SID antes ficar melhor e mais rápido.
export ORACLE_SID=base impdp backup/<senha> directory=imp_DIR dumpfile=<arquivo>. dmp logfile=owner_dest.imp remap_schema=owner:owner_dest tables=owner.tabela impdp backup/<senha> directory=IMP_dir dumpfile=spo_01.dmp logfile= spo_backup_20120724.imp remap_schema= spo:spo_backup_20120724 impdp backup/<senha> directory=IMP_DIR dumpfile= pwda_%u.dmp logfile= pwda.impdp schemas=pwda
usando parfile
cat <instance_name>_imp.par userid=BACKUP/<senha> directory=imp_dir
comando
impdp parfile=<instance_name>_imp.par dumpfile=<arquivo>. dmp logfile= owner_dest.imp remap_schema=owner:owner_dest tables= owner.tabela impdp parfile=<instance_name>_imp.par dumpfile=spo_01.dmp logfile= spo_backup_20120724.imp remap_schema= spo:spo_backup_20120724 impdp parfile=<instance_name>_imp.par dumpfile= pwda_%u.dmp logfile= pwda.impdp schemas=pwda
usando a rede o comando completo ficaria assim
impdp backup/<senha>@base directory=imp_DIR dumpfile =<arquivo>.dmp logfile= owner_dest.imp remap_schema=owner:owner_dest tables= owner.tabela impdp backup/<senha>@base directory=IMP_dir dumpfile= spo_01.dmp logfile= spo_backup_20120724.imp remap_schema= spo:spo_backup_20120724 impdp backup/<senha>@base directory=IMP_DIR dumpfile= pwda_%u.dmp logfile= pwda.impdp schemas=pwda
