I am trying to install Oracle 12.1.0.2 on Windows 7 running under Parallels on my MacBook Pro (Retina, 15-inch, Mid 2015).
However, some of the Oracle command-line tools are hanging just before they should terminate. Example commands are "lsnrctl" and "tnsping". Taking the latter as an example:
C:\Users\mgd>tnsping 10.4.8.150_UNICODE
TNS Ping Utility for 64-bit Windows: Version 12.1.0.2.0 - Production on 06 OCT-2015 14:10:48
Copyright (c) 1997, 2014, Oracle. All rights reserved.
Used parameter files:
C:\oracle\product\12.1.0\dbhome\network\admin\sqlnet.ora
Used TNSNAMES adapter to resolve the alias
Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)
(HOST = 10.4.8.150)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = unicode)))
OK (20 msec)
...program hung here for minutes...
In this case the command did what it should (see the last line "OK (20 msec)") and was expected to terminate immediately after.
Using Sysinternals (Microsoft Technet) Process Explorer, I got a stack trace from the hanging process:
ntoskrnl.exe!memset+0x61a

mswsock.dll+0x5941
kernel32.dll!BaseThreadInitThunk+0xd
ntdll.dll!RtlUserThreadStart+0x21
To me it looks like the process is stuck waiting for a Windows Mutex as part of some network operation in the Winsock layer (mswsock.dll) - maybe as part of network shutdown for the process.
Does anybody have an idea of what is wrong or have you seen similar behaviour with other "client" software?
