D GRS,CONTENTIONduring a time period in which the performance problem is observed. SYS.BPX.A000.FSLIT.FILESYS.LSN represents HFS latches. Latch sets with a numeric suffix are file latches, specifically SYS.BPX.A000.FSLIT.FILESYS.LSN.01. If you detect file latch contention, the best way to determine the exact HFS file causing the problem is with an SVC dump, also collected during a time period in which contention occurred. You will need to dump one of the OMVS data spaces to get the file information.
DUMP COMM=(description of problem) Reply to dump WTO, where serverproc is the name of your WebSphere® Server address space(s) JOBNAME=(OMVS,Serverproc),DSPNAME=('OMVS'.SYSZBPX1,'OMVS'.SYSZBPX2), SDATA=(CSA,GRSQ,LPA,NUC,PSA,RGN,SQA,TRT,SUM)
