Re: Info. on Informix Universal Server

Seth, I am not sure where you got your information about the PLS blade, but to the best of my knowledge, the PLS blade (which I maintained for over a year) does not use free() -- it uses mi_free(), the Illustra server API call. When last I worked on it, Informix was investigating the problems with the use of mi_free on IRIX 6.2 encountered in the PLS blade--the problem had not yet been isolated. In a more general thread: From my experience, the biggest problem with both Illustra and IUS DataBlades, especially low-level blades like text, is that they require a major joint effort, in development, maintenance and customer support, between the third-party organization and Informix to ensure that the integration works correctly with the server. This level of support requires a significant commitment from both parties. Without a strong level of commitment from both parties, data corruption and server crashes could be a problem -- just as it would be if Informix was not committed to their servers. Please do not get me wrong -- I strongly believe in the Informix Universal Server and DataBlade technologies. But, they are complex technologies and therefore require complex solutions.
