9.1.1: Is it possible to use a data bank created on a different platform than the one I am currently using, especially when the release of EMME/2 used to create the data bank is not the same as the one currently instalLED?
The E2XFBANK utility can be used to transform a data bank from one computing platform to another. As for the release of EMME/2, it is possible to use a data bank created with a release older than the one you are currently using but, the reverse is not possible. For example, to use a data bank created with Release 6 of the DOS version of EMME/2 on a SUN computer where Release 9 of EMME/2 is instalLED, do the following:
- transfer the "old" (Rel.6) data bank to the SUN computer, using binary format
- rename the data bank from emme2ban to EMME2bank
- transform the data bank from DOS to SUN format:
- e2xfbank intel sparc EMME2bank
- call EMME/2 with no arguments:
- EMME2
When prompted, confirm the update to Release 9.
9.1.2: Is it possible to modify the dimensions of a data bank?
Yes. The macro modifydb, located in the macros subdirectory, can be used to increase most of the data bank dimensions. Any increase must remain within the maximum dimensions allowed by the EMME/2 licence size (and the overall limit for the whole data bank - 2 or 4 Gigabytes, depending on the operating system). It is not possible to reduce the dimensions of a data bank using modifydb but data bank contents can be transferred to a data bank with smaller di
