Local fix
Problem summary
**************************************************************** * USERS AFFECTED: IMS V12 OTMA customers using flood control * **************************************************************** * PROBLEM DESCRIPTION: Need to crease the flood limit of 9999 * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** The current OTMA flood limit for input messages for a member is 9999. And the default global flood limit for all members is 8000. These limits could potentially be too low for customers.
Problem conclusion
Temporary fix
Comments
OTMA flood limit for input messages for a member has been increased from 9999 to 65000. The default global flood limit for all members remain unchanged, however it can be set to a higher limit if the member limit in client descriptor is higher. See the following doc changes below. OTMA modules (DFSYDPD0, DFSYC490, DFSYSND0, DFSYIDC0, DFSYMOM0, and DFSYFD00) were enhanced to expand the limit from 9999 to 65000. OTMA macros (DFSYMSG, DFSYMCB and DFSYMTE) were enhanced to accept higher limit stored in the 2-byte fields. IMS macro DISPLAY was enhanced so that /DIS OTMA and /DIS TMEMBER can show 5-char limit values under TIB and INPT header. And the length for XCF-STATUS field was reduced from 12-char to 11-char. =========================================================== UPDATES TO IMS RELEASE PLANNING GUIDE ARE: =========================================================== IMS OTMA flood limit for input messages has been increased from 9999 to 65000. =========================================================== UPDATES TO IMS SYSTEM DEFINITION ARE: =========================================================== INPT= PARAMETER FOR OTMA CLIENT DESCRIPTOR INPT= A 1- to 5-digit decimal integer that indicates the maximum number of flood limit for input messages for this member. Valid values are 200 - 65000 or 0. If the value is 1 - 200, it is treated as 200. If the value is over 65000, a value of 65000 is used. When this value is higher than the default global flood limit of 8000, the default global flood limit will be changed to this value. If more than one client descriptors have INPT values higher than the default global flood limit, the highest value will become the default global flood limit. =========================================================== UPDATES TO IMS COMMANDS ARE: =========================================================== Add changes to /START TMEM command INPUT A 1- to 5-digit decimal integer that indicates the maximum number of flood limit for input messages for this member or for OTMA server. Valid values are 200 - 65000 or 0. If the value is 1 - 200, it is treated as 200. If the value is over 65000, a value of 65000 is used. =========================================================== UPDATES TO IMS MESSAGES AND CODES ARE: =========================================================== Change IMS message DFS4388W as follows: DFS4388W THE TOTAL OTMA INPUT MESSAGES(TIB) HAVE REACHED OR EXCEEDED THE GLOBAL LIMIT nnn =========================================================== UPDATES TO IMS COMMUNICATIONS AND CONNECTIONS GUIDE =========================================================== OTMA message prefix State Data section Table 1. Server-Available and Client-Bid command format At offset 62 for Message flood threshold value Change 0-9999 to 0-65000
