Due to the incompatibility of 64-bit and 32-bit shared memory versions, on platforms (operating system and architecture) where OpenEdge Release 11 supports both 64-bit and 32-bit versions, and both products can be simultaneously installed, note the following:
Both the 32-bit and 64-bit version of OpenEdge on one platform, can access the same OpenEdge database. There is no need to convert or do a dump and load.
Shared memory is not supported in a mixed bit mode. If a 64-bit server is started against the database, 32-bit clients cannot connect using shared memory. 32-bit clients can connect to the 64-bit server using client/server connections. The reverse is also true: if a 32-bit server is started against the database, 64-bit clients cannot connect using shared memory. The 64-bit clients have to connect using client/server connections.
Mixing of servers is also not supported. The database can only have 32-bit servers or 64-bit servers running, never some of each.
Both the 32-bit and 64-bit version of OpenEdge on one platform, can access the same OpenEdge database. There is no need to convert or do a dump and load.
