Error description
IMS COLLECT PERFORMANCE PROBLEM DUE TO LOOPING IMS TRANSACTION AND TABLEFLUSH SETTING USED IN COLLECT DOES NOT HELP.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of the TDSz IMS CSQ feature who * * use or might consider using the TABLEFLUSH * * DRLIPARM statement. * **************************************************************** * PROBLEM DESCRIPTION: Use of the TABLEFLUSH parameter does * * not provide the expected improvement * * in TDSz IMS CSQ feature log collection * * performance. * **************************************************************** * RECOMMENDATION: APPLY THE PTF FIXING THIS APAR * **************************************************************** An internal field used to determine whether log record control blocks had aged sufficiently to be candidates for writing to incomplete composite records to free storage is sometimes reset incorrectly, causing the control blocks to appear "younger" than they actually are. As a result they are excluded from TABLEFLUSH processing and the expected reduction in resource usage and consequent performance improvement is not realised.
Problem conclusion
TABLEFLUSH processing has been enhanced to provide the expected control block flushing and corresponding potential performance gains. New DRLIPARM parameters have been added to provide better control of the tableflush process, and new messages have been added to provide more information on the results of the process. New documentation has been provided to allow users to better understand and exploit the tableflush process. 710Y 801Y DRLDOC72 DRLIDOUW DRLIPOUW DRLPCOLL DRLPLOPR DRLPMG03 DRLPMG20 DRLPXASC DRLPXB10 DRLPXFRE DRLPXMED DRLPXMFO DRLPXPCL DRLPXWDG DRLSIA1C DRLSIA1E DRLSIA1F DRLSIA1H DRLSIA1K DRLSIA1L DRLSIA1P DRLSIA1R DRLSIA1T DRLSIA1V DRLSIA1W DRLSIA1X DRLSIA1Y DRLSIA1Z DRLSIA12 DRLSIDCM DRLSIFAL DRLSI71C DRLSI71E DRLSI71F DRLSI71H DRLSI71K DRLSI71L DRLSI71P DRLSI71R DRLSI71T DRLSI71V DRLSI71W DRLSI71X DRLSI71Y DRLSI71Z DRLSI712 DRLSI81C DRLSI81E DRLSI81F DRLSI81H DRLSI81K DRLSI81L DRLSI81P DRLSI81R DRLSI81T DRLSI81V DRLSI81W DRLSI81X DRLSI81Y DRLSI81Z DRLSI812 DRLSI91C DRLSI91E DRLSI91F DRLSI91H DRLSI91K DRLSI91L DRLSI91P DRLSI91R DRLSI91T DRLSI91V DRLSI91W DRLSI91X DRLSI91Y DRLSI91Z DRLSI912 DRLSLOGP DRLSLOPR DRLXXENV DRLYXENV DRL2CSQF DRL2CSQJ DRL2CSQL DRL2CSQR DRL2CSQT DRL2CSQW DRL2CSQZ DRL2IFWC DRL2ITCR DRL3CSQ2 HLJ0710 HLJ0710J HLJ0801 HLJ0801J
