Error description
When using the default shmbase address for a Win32 server and setting GL_USEGLU in the evnironment where the instance is started, onstat will fail with a mapViewFileOfEx error: C:\Windows\system32>onstat - MapViewOfFileEx: w32ec=487 at nt_shm.c:767 12:07:28 shmat: [22]: operating system error 12:07:28 Client could not attach server shared memory segment, use IFX_XFER_SHM BASE. onstat: Cannot attach to shared memory. errno = 22 This is because the 32-glu34.dll is loaded at 0x1000000. Changing the shared memory base address to a value bigger than 0x1000000 + size resolves this problem.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: * * All Windows users * **************************************************************** * PROBLEM DESCRIPTION: * * When the ICU is loaded by way of GL_USEGLU being set in the * * environment, and the SHMBASE setting in the ONCONFIG file is * * set to its default value, the onstat utility will display an * * error message when it attempts to establish a connection to * * the server. This occurs because the memory space used by the * * ICU DLL is overlapping with the shared memory segment. * **************************************************************** * RECOMMENDATION: * * Upgrade to IDS version 11.50.xC6 and above. * ****************************************************************
Problem conclusion
Starting with IDS 11.50.xC6, the ICU DLL will be loaded with a different base address on Windows.
