The Open Procedure for service "SQL_ANYWHERE" in DLL "c:\sybase\sqlany50\win32\sqlactrs.dll" failed. Performance data for this service will not be available. Status code returned is DWORD 0.

Если кому интересно, вот что ответили по этому поводу на sybase.com:

This error is not produced by SQL Anywhere but instead by the operating
system. The performance monitor is trying to start monitoring all
applications that it has listed in the registry. When it tries to
make a call to SQLACTRS.dll while the engine is not running it is unable
to get performance data.

The workaround would be to delete the registry folder:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SQL_Anywhere\Performance


Note that you may no longer be able to access performance data for SQL
Anywhere after making this change.

Could it also be caused by a second instance of the engine starting? I
seem to remember being told only the first one gets to use the
counters, the second one gets the message.

Or it could be a hosed registry... which in my experience is unfixable
without reinstalling Windows.

And if you don't need the counters, you just ignore the message :)
