Hi, Has anyone installed SOA Suite 11.1.1.3.0 in a solaris 10 64bit sparc zone. It is totally unusable due to some sort of bug or configuration issue, Oracle can't reproduce the problem apparently. We've installed the same SOA version on linux and windows and they don't exhibit the same issue. To summarize the solaris problem, I can see using truss that EVERYTIME you login or click on something in BPM composer (and anything else by the looks of things) , the weblogic process runs the stat unix system call about 2000 times/s, it looks like most of the files it is stat'ing are java class files that don't exist, couple of examples below. 99% of the cpu consumption is for these calls. So in other words it is only spending 1% of the CPU doing something useful like rendering the screens. /98: stat("/u01/apps/oracle/product/11.1.1/middleware/user_projects/domains/b ase_domain/servers/soa_server1/tmp/_WL_user/BPMComposer/p2cox8/com/sun/f aces/renderkit/html_basic/ButtonRenderer.class", 0xFFFFFFFEE5BE5FC8) Err#2 ENOENT /98: stat("/u01/apps/oracle/product/11.1.1/middleware/user_projects/domains/b ase_domain/servers/soa_server1/tmp/_WL_user/BPMComposer/p2cox8/war/WEB-I NF/classes/oracle/jdevimpl/webapp/faces/metadata/StandardFacesMetadataMa pper.class", 0xFFFFFFFEE5BE5EA8) Err#2 ENOENT /98: stat("/u01/apps/oracle/product/11.1.1/middleware/user_projects/domains/b ase_domain/servers/soa_server1/tmp/_WL_user/BPMComposer/p2cox8/oracle/jd evimpl/webapp/faces/metadata/StandardFacesMetadataMapper.class", 0xFFFFFFFEE5BE5FC8) Err#2 ENOENT /98: stat("/u01/apps/oracle/product/11.1.1/middleware/user_projects/domains/b ase_domain/servers/soa_server1/tmp/_WL_user/BPMComposer/p2cox8/war/WEB-I NF/classes/org/apache/taglibs/standard/tag/common/fmt/SetTimeZoneSupport .class", 0xFFFFFFFEE5BE5EA8) Err#2 ENOENT /98: stat("/u01/apps/oracle/product/11.1.1/middleware/user_projects/domains/b ase_domain/servers/soa_server1/tmp/_WL_user/BPMComposer/p2cox8/org/apach e/taglibs/standard/tag/common/fmt/SetTimeZoneSupport.class", 0xFFFFFFFEE5BE5FC8) Err#2 ENOENT /98: stat("/u01/apps/oracle/product/11.1.1/middleware/user_projects/domains/b ase_domain/servers/soa_server1/tmp/_WL_user/BPMComposer/p2cox8/war/WEB-I NF/classes/oracle/adf/controller/v2/context/PageLifecycleContext.class", 0xFFFFFFFEE5BE5EA8) Err#2 ENOENT thankyou Bill Banham
