在使用adrci命令清空日志时遇到错误：“DIA-48448: This command does not support multiple ADR homes”如何解决呢？如下所示
$ adrci
ADRCI: Release 19.0.0.0.0 - Production on Mon Apr 24 17:13:32 2023

ADR base = "/opt/oracle19c"
adrci> purge -age 10080 -type incident
DIA-48448: This command does not support multiple ADR homes
其实遇到这个错误是因为ADR的home目录有多个，我们需要指定某一个具体的home目录，才能清理日志,如下所示
adrci> show homes;
ADR Homes:
diag/rdbms/test/ctest
diag/rdbms/test/gsp
diag/rdbms/test/kerry
diag/rdbms/test/mydb
diag/rdbms/kerry/kerry
adrci>
adrci> set home diag/rdbms/test/kerry
adrci> purge -age 10080 -type incident
