Estimate the number of logical-log files

The LOGFILES parameter provides the number of logical-log files at system initialization or restart. If all your logical-log files are the same size, you can calculate the total space allocated to the logical-log files as follows:
total logical log space = LOGFILES * LOGSIZE

If the database server contains log files of different sizes, you cannot use the (LOGFILES * LOGSIZE) expression to calculate the size of the logical log. Instead, you must add the sizes for each individual log file on disk. Check the size field in the onstat -l output. For more information, see The onstat -l command.

For information about LOGSIZE, LOGFILES, and NETTYPE, see the topics about configuration parameters in the HCL Informix® Administrator's Reference.
