Symptoms

還原作業速度緩慢，最終可能會失敗，並出現類似以下的錯誤：
 

avtar Error <5183>: No backups with a label matching '' or backuptag 'c-555-444-ff' or labelnum 0 were found.
avtar Error <5920>: File 12/remsdev/CONTROLFILE.remsdev.c-555-444-ff not found.




 

Cause

還原方式 autobackup 表示 Oracle 軟體可能會對 Avamar 進行大量查詢。
如果此類查詢超過 255 個，並且每個查詢持續大約一分鐘，這會大大減慢還原過程。


範例：

restore spfile to '/oracle/admin/remsdev/avamar/spfileremsdev.ora' from autobackup;

Resolution

還原 spfile 或 controlfile 是使用其實際名稱而不是 autobackup，像這樣：
 

run {
allocate channel c1 type sbt PARMS="SBT_LIBRARY=/usr/local/avamar/lib/libobk_avamar64.so" format '%d_%U';
send channel c1 '"--prefix=12/remsdev/CONTROLFILE.remsdev." "--flagfile=/oracle/admin/remsdev/avamar/my-avtar-flags.txt" "--bindir=/usr/local/avamar/bin"';
restore spfile to '/oracle/admin/remsdev/avamar/spfileremsdev.ora' from  CONTROLFILE.remsdev.c-12345-6789-01 ;
release channel c1;
