Mitsui Bank has decided not to use IBM Japan’s SAIL package as the basis of its third on-line system – a transaction processing system being implemented by all the major banks: Mitsui Bank’s decision is in contrast to Fuji Bank and Mitsubishi Bank, both of which are using SAIL, which is built around IMS with 31-bit XA capability; Mitsui Bank’s solution is to use an extended version of its current product, JCCP, which was also developed in conjunction with IBM, but at present has only has 24-bit addressing; Mitsui will rewrite it for XA rather than use SAIL, its main objection to the latter being that it takes up a collossal 45% of the 2Gb address space that is the Extended Architecture limit, and as a result, the bank feared that processing speed and response times would be adversely affected.
