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.
