PH33304: IDZ COBOL EDITOR FREEZES WHEN TRYING TO OPEN A COPYBOOK

APAR status

• Closed as program error.

Error description

• IBM Developer for z/OS - IDz - v14.2.4 client freezes when
  trying to open a copybook in the COBOL editor while other
  copybooks are being downloaded.
  
  Steps to reproduce:
  
  1) Configure a SYSLIB on a property group with multiple PDS
  having many members (30 000 or more).
  Like SYSLIB=TST.MBR.PDS25K TST.MBR.PDSE25K TST.MBR.PDSE50K
  TST.COBOL.PDS30K.COPYLIB
  2) Edit a remote COBOL program having copybooks in a PDS with
  many members and which is the last one on the SYSLIB (ie
  TST.COBOL.PDS30K.COPYLIB)
  3) While the progress view shows that copybooks are being
  downloaded, right-click on a copy statement in the editor and
  select menu "Open copy member".
  4) Observe that IDz client user interface is frozen for some
  minutes.
  

Local fix

• Set SYSLIB with only the required datasets or datasets with less
  members.
  

Problem summary

• When using the COBOL editor's open include member action while
  resolving copybooks with a very large SYSLIB, the client can
  appear to freeze
  

Problem conclusion

• When the SYSLIB contains over a hundred thousand members there
  can be contention between the worker thread and the main thread
  that is trying to resolve copybooks at the same time with a
  recent change that attempts to query all the copybooks in the
  SYSLIB upfront.
  

Temporary fix
