IJ04281: STARTUP TIME INCREASE AFTER APPLYING APAR IV96905

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  The startup time is increased if ulimit in the system is a large
  value (like 64K or more).
  

Local fix

• Set the environment variable  IBM_JAVA_FDLIMIT=<file descriptor
  count> to a smaller value.
  

Problem summary

• Modified the file description table implementation similar to
  the reference implementation to resolve the issue report in APAR
  IV96905. As a result, the complete file descriptor table
  initialization occurred during the startup of the JVM.
  

Problem conclusion

• JDK has been updated to do lazy initialization of the file
  descriptor table.
  .
