IT30935: ABSOLUTE-REWRITE PARAMETER IN A URL-REWRITE DUPLICATES ITSELF

Fix packs for DataPower Gateway version 2018.4

APAR status

• Closed as program error.

Error description

• Parameters can grow over time in the url-rewrite object, which
  might eventually impact services with higher CPU, load, memory,
  or any combination.
  

Local fix

• Use the CLI config (config://domain/domain.cfg) to reset the
  object and put back the original entries. For example:
  
  Inside the cfg
  file find entries of..:
  
  url-rewrite "abcd"
  absolute-rewrite
  "(.*)" "/somelink" "" off on off
  absolute-rewrite "(.*)"
  "/somelink" "" off on off
  absolute-rewrite "(.*)" "/somelink"
  "" off on off
  ...duplicated many times
  exit
  
  Use the DataPower CLI
  to reset the object and add each correct
  entry back (omitting any duplicates):
  
  configure terminal
  switch domain domainName
  
  url-rewrite "abcd"
  reset
  absolute-rewrite "(.*)"
  "/somelink" "" off on off
  exit
  write memory
  y
  

Problem summary

• DataPower user who configure URL rewrite rules, SAML attributes,
  processing policy (Stylepolicy) might be able to enter duplicate
  entries.
  

Problem conclusion

• Fix is available in 2018.4.1.10
