Fix (APAR): PK52139 Status: Fix Release: 6.1.0.9,6.1.0.11 Operating System: AIX,HP-UX,i5/OS,Linux,Linux pSeries,Linux zSeries,OS/400,Solaris,Windows Supersedes Fixes: CMVC Defect: PK51239 Byte size of APAR: 25512 Date: 2007-09-21 Abstract: Web Services maxConnection Property Fix Description/symptom of problem: PK52139 resolves the following problem: ERROR DESCRIPTION: WebServices MAX Connections property fix. LOCAL FIX: None. PROBLEM SUMMARY USERS AFFECTED: IBM WebSphere Application Server version 6.1 users of Web Services PROBLEM DESCRIPTION: Web Services maxConnection Property Fix RECOMMENDATION: None The minimum and maximum connection size is limited between 5 and 25 regardless of what is set for the maxConnection property. This is a performance enhancement. PROBLEM CONCLUSION: The code has been changed to remove the limitation of 25 as the maximum connections in the Web Container threadpool, so you can set the maxConnection property. It is strongly recommended that you set your maxConnection size to be at most 1/2 the size of the Web Container threadpool size to avoid performance degradation. This has also been documented in the Information Center. The fix for this APAR is currently targeted for inclusion in cumulative fix 6.1.0.13.
