APAR NUMBER: PJ32540 PRODUCT: TPF4 FUNCTIONAL AREA: CONTINUOUS DATA COLLECTION (CDC) SHIPPED IN PUT: 23 ABSTRACT: Various inaccuracies in CDC data APAR CONTENTS: FEATURE TYPE STATUS NAME Base C Changed source/rt/base/cdcp.c Base Assembler Changed source/rt/base/cdcr.asm PREREQUISITE APARS: To be applied in order listed. Base C Changed source/rt/base/cdcp.c PJ27095(12) PJ27775(15) PJ28097(15) PJ29925(19) PJ30137(19) PJ30215(20) PJ30233(20) PJ30253(20) PJ30251(20) PJ30465(20) PJ30503(20) PJ30701(20) PJ30589(20) PJ30610(20) PJ30946(20) PJ31004(20) PJ31135(20) PJ31144(21) PJ31207(21) PJ31664(21) PJ31660(21) PJ32257(23) PJ32358(23) Base Assembler Changed source/rt/base/cdcr.asm PJ27095(12) PJ27343(13) PJ28097(15) PJ29811(19) PJ29925(19) PJ30503(20) PJ30701(20) PJ30946(20) PJ31716(21) COMMENTS: The following inaccuracies of CDC data was reported: 1. Incorrect values for Suspend List and VCT List per i-stream. 2. Incorrect values for Routed Ents (by swisc) per i-stream 3. Incorrect values in MQ Summary fields with KB/s counts for persistent and nonpersistent messages. SOLUTION: The following updates have been made to the CDC code on TPF for the problems listed above. 1. Incorrect Suspend List and VCT List values appear in both CDC_SYSTEM_LIST and CDC_ISTREAM metrics. The CDC code which access the CPU loop Suspend and VCT Lists was not looping through each i-streams prefix page when obtaining the values. Code in cdcr.asm has been corrected to do so. 2. Incorrect Routed Entry data appeared in the CDC_ISTREAM metric. Routed entry data is picked up from storage accessible via the CMMSWIS CINFC tag. Specifically from the DCSWIENT label. The code to access the routed entries from that storage was not correct. Code in cdcr.asm has been corrected. 3. Incorrect values in the CDC_MQ_SUMMAY metric is due to delta calculations across collections not being taken for QAddMessageLen and QMessageLen. Code in cdcp.c has been corrected. DEPENDENCIES SEGMENTS TO BE ASSEMBLED OR COMPILED: None. SEGMENTS TO BE LINK EDITED: cdcp40.exe (Shipped in Tar File) COREQS: None. MIGRATION CONSIDERATIONS: None. UPDATED INFORMATION UNITS: None.
