I've got trouble starting DB2 windows services. I got this error :
"Windows could not start the DB2 - DB2COPY1 - DB2 on Local Computer. For more information, review the System Event Log. Th this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code -1220"
SQL1220N The database manager shared memory set cannot be allocated.
The database manager could not allocate its shared memory set. The cause
of this error may be insufficient memory resources either for the
database manager or the environment in which its operation is being
attempted. Memory resources that can cause this error include:
* The number of shared memory identifiers allocated in the system
* The size of the shared memory segment
* The amount of paging or swapping space available in the system
* The amount of physical memory available in the system
One or more of the following:
* Validate that sufficient memory resources are available to satisfy
the database manager's requirements, and those of the other programs
running on the system.
* On Linux 32-bit, increase the kernel parameter shmmax to 256 MB. On
Linux 64-bit, increase the kernel parameter shmmax to 1GB.
* Reduce database manager's memory requirement for this memory set by
reducing the database manager configuration parameters which affect
it. These are: fenced_pool and, numdb.
* Where appropriate, stop other programs using the system.
have you tried db2start from the command line - maybe the license
