Comments on: RRN Max http://itknowledgeexchange.techtarget.com/itanswers/rrn-max/ Fri, 24 May 2013 12:30:07 +0000 hourly 1 By: bvining http://itknowledgeexchange.techtarget.com/itanswers/rrn-max/#comment-76540 bvining Tue, 27 Apr 2010 14:17:16 +0000 #comment-76540 This is just a wild guess, but when I see a maximum value of 999,999,999 I immediately wonder if there’s a RPG program involved with a variable (for instance RRN) defined as ’9b 0′ (that is, a 9-digit binary field). This definition cannot retain a value exceeding 999999999. If this is the case, then chaning the RPG field to ’10i 0′ (a 10-digit integer field) will get you past 999999999.

As noted by others, 999999999 is not a DB2 limit.

For V5R2, V5R3 and V5R4, the maximum number of records in a physical file member is 4,294,967,288. Since we needed to have more records in that file, we now have a multiple membered version of it, where each member is defined as an SQL partition, along with an SQL index that sees all the members at once.

So, having more than a million records should not be a problem, unless you’re on an older operating system, as I’m not sure how far back the 4.2 billion limit goes.

Note that the maximum number of records in a member can be reduced if the number of bytes exceeds the maximum, or if the access path size (of ANY of the logicals based on the physical file) exceeds the maximum allowed.
