Standard Informix Authentication on unix will perform a getpwnam() call to retrieve the encrypted shadow password from the OS, it will then compare an encrypted version of the password supplied by the client against this, and if they match, authen...
Online.log could also print session detail of additional memory segment allocation
In high usage OLTP systems, it is a hard work to identify which session(s) is(are) demanding too much memory from the Informix engine.A good thing for us to help to identify abnormal programs execution/behaviour would be to print session details (...
Informix has a rows/page limit of 255 rows/page. Perhaps this was not a problem originally but over time we have seen new features: larger page sizes (up to 16 kB against 2 kB or 4 kB previously, dependent on operating system). compression option....
