SKGFQ OSD: Look for SBT Trace messages in file /oracle/app/oracle/diag/rdbms/sevendb/sevendb/trace/sbtio.log

/oracle/app/oracle/product/11.2.0/dbhome_1/bin/sbttest
[oracle@SsevendbS01 lib]$ sbttest /etc/hosts
The sbt function pointers are loaded from oracle.static library.
libobk.so could not be loaded. Check that it is installed
查了很多资料发现：
导致上述结果的原因是Oracle没有和NBU做链接，
cd $ORACLE_HOME/lib
ln /usr/openv/netbackup/bin/libobk.so
操作后重新测试SBTTEST：
[oracle@SsevendbS01 lib]$ sbttest /etc/hosts
The sbt function pointers are loaded from libobk.so library.
-- sbtinit succeeded
-- sbtinit (2nd time) succeeded
sbtinit: Media manager supports SBT API version 2.0
sbtinit: Media manager is version 5.0.0.0
sbtinit: vendor description string=Veritas NetBackup for Oracle - Release 7.5 (2013061020)
sbtinit: allocated sbt context area of 8 bytes
sbtinit: proxy copy is supported
-- sbtinit2 succeeded
-- regular_backup_restore starts ................................
OK，配置成功。

以上报错提示找不到备份片，通常此等报错均是跟NBU的media server有关，通过查看/etc/hosts 和 bp.conf 发现没有问题，最终将问题定位到NB_ORA_CLIENT=PsevendbS01上，查看NBU备份脚本，其中client为PsevendbS而不是PsevendbS01，更改恢复脚本后，恢复成功。
