Cannot open audit file

Hello Friends,

As a part of re-platform activity our production application servers are moved from AIX to Windows operating system. But CI is still in AIX.

From the next day of re-platform activity we are getting the SM21 error log as "Cannot open audit file: /migrate/<SID>/audit/log\<DATE>.AUD. This log is generating only on Windows application servers and not on CI(AIX).

All the file systems are properly mounted from AIX to Windows.

DIR_AUDIT parameter value also maintained in default profile as /migrate/<SID>/audit/log

Can any one please suggest

Thanks in advance,

Mahi.
