Increasing the number of data lists

If the number of data lists specified via the MAXQUEUES or MAXTABLES server parameter is too small, an attempt to allocate a new data list will fail with message DFHXQ0443 or message DFHCF0443.

There is no way to increase the number of lists without deleting and recreating the structure, which necessitates closing down all of the servers temporarily. You cannot use system-managed rebuild to increase the number of data lists because it copies this number from the existing structure.

You can preserve existing data by using the server program to unload it to a sequential file, and then using SETXCF FORCE to delete the existing structure. You can then use the server program again to reload the data, and allocate a new structure with the appropriate MAXQUEUES or MAXTABLES parameter.
