Symptoms

还原作速度缓慢，最终可能会失败，并显示类似于以下内容的错误：
 

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

还原方式 autobackup 这意味着 Oracle 软件可能会对 Avamar 进行大量查询。
如果此类查询超过 255 个，并且每个查询持续约一分钟，则会显著减慢还原过程的速度。


示例：

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

Resolution

还原 spfile 或 controlfile 是使用其实际名称而不是 autobackup喜欢这个：
 

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;
