Error description This APAR addresses defects in WebSphere Application Server V4.0.1 for z/OS and OS/390.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V4.0.1 for z/OS and OS/390. * **************************************************************** * PROBLEM DESCRIPTION: This APAR includes IBM internal fixes * * for the WebSphere Application Server * * for z/OS and OS/390. * * * * Internal defect descriptions: * * * * (84415) Defect to rollup to distributed * * WAS4.04 level. * * The customer is porting an application * * from WebSphere AE to OS/390 and * * receives a compile error for a method * * which is missing in the OS/390 * * dynacache code. * * * * (84444)The HttpDateUpdater daemon * * thread (see APAR PQ67396) causes * * uncessary page swapping and, hence, * * degrads system performance. * * * * (84454) Increment the Service level to * * W401407. * **************************************************************** * RECOMMENDATION: * **************************************************************** This APAR includes fixes for internal defects found in WebSphere Application Server Version V4.0.1. (84415) Defect to rollup to the distributed WAS4.04 level. he customer's application fails to compile on OS/390 with the following error: cannot resolve symbol javac symbol : method setStoreAttributes (boolean) javac location: class com.ibm.servlet.dynacache.FragmentInfo javac tempFragmentInfo.setStoreAttributes(false) The application compiles successfully on WebSphere AE. The setStoreAttributes() method was added to WebSphere AE in FixPack4. The OS/390 Dynamic Caching code is at FixPack3 level and needs to be updated to FixPack4. (84441) HttpDateUpdater thread is the thread to get the current time used by the utility class HttpDate which parse/write RFC1123 formatted date in the HTTP message headers. The HttpDateUpdater daemon thread runs as an infinite loop. Inside the loop iteration, it gets the current time and then sleeps one second. By doing sleep/awake, it causes page swapping even there is no request for its service. (84454) Increment the Service level to W401407.Problem conclusion (84415) Rolled up the code to the WebSphere AE FixPack 4 level. The Dynamic Caching code for OS/390 was updated to the WebSphere AE FixPack4 level plus some FixPack5 Dynacache fixes. (84441) Since the cost for doing System.currentTimeMillis() is relatively small comparing with the cost for constant page swapping every second, the HttpDate code in the WebSphere Application Server Web container code has been changed to: (1) Not to start the HttpDateUpdater daemon thread (2) Issue System.currentTimeMillis() to get current time when needed. (84454) The service level was changed to W401407. APAR PQ69293 requires changes to documentation. The following description of the new environment variable will be added to Appendix A of WebSphere Application Server V4.0.1 for z/OS and OS/390: Assembling J2EE Applications, SA22-7836-05, and Appendix A of WebSphere Application Server V4.0.1 for z/OS and OS/390: Installation and Customization, GA22-7834-06: WS_SMF_RECORDING=ON|OFF Specifies whether or not Web container SMF activity and interval records are being written. When this environment variable is set to OFF, SMF activity and interval records will no longer be written for the Web container. However, they will continue to be written for the J2EE server. The default value is ON. Also, the following note will be added to Step 4 in Chapter 11, Section "Enabling SMF recording" in WebSphere Application Server V4.0.1 for z/OS and OS/390: Operations and Administration, SA22-7835-05 Note: If you want to enable the recording of SMF activity and interval records for the J2EE container without enabling the recording of SMF activity and interval records for the Web container, use the Administration Application to add the WS_SMF_RECORDING=OFF environment variable to the current.env file. APAR PQ69293 is associated with SERVICE LEVEL W401407 of WebSphere Application Server V4.0.1 for z/OS and OS/390.Temporary fix Comments **** PE03/02/21 FIX IN ERROR. SEE APAR PQ70466 FOR DESCRIPTION
