IO09137: SLOW PERFORMANCE WHEN VIEWING LARGE NUMBER OF ACLS

APAR status

• Closed as program error.

Error description

• When viewing a large number of ACLs in the System Admin Client
  there is very slow performance. Typically 10,000 ACLs.
  

Local fix

• N/A
  

Problem summary

• If a Content Manager library server has many Access Control
  Lists (ACLs) defined in the system, any user's action to
  retrieve all the ACL names is very slow. For example, if you
  have about 20,000 ACLs defined in the system, the total
  retrieval time is about six minutes.
  
  This is PMR 00584,999,693.
  

Problem conclusion

• The code was changed in the PACLMgmtImpICM's
  listOrRetrieveACLs() method, so that when it lists ACL by name
  or by ID, there is no longer a lookup in the string vector of
  names to see if the entry in the loop of returned data is new
  (the old method of looking up a name in a string vector of names
  is too slow). The changed code checks to see if the ID is
  changed or not. If changed, the API creates a new entry, and the
  ID or name is added to the returning vector. Otherwise, the API
  does nothing for that entry in the loop.
  

Temporary fix

• n/a
