Updated information to required PTFs for Rational COBOL Runtime for z/OS V6.0.1


We recently found out that the latest PTF for Rational COBOL Runtime for z/OS V6.0.1 that corresponded to RBD V7.1.0.2 had a problem in it. The problem was that calls from a V7.1.0.2 client (EGL debugger, jsfHandler, etc.) which called EGL programs or used COMMPTR as the parmform would fail.

As a result new PTFs have been created so, the list to install is as follows to get current maintenane based on the level of RBD you are using. Installing UK42740 will update to the latest, but all need to be installed (following the install notes).


v6010 : /
v7000 : UK24108
v7100 : UK29575
v7101 : UK40726
v7102 : UK42718
v7510 : UK42740


with these important install notes

  • UK24108 requires that the base product is accepted
  • UK24108 and UK40726 must be applied in two different steps
    (doing both in the same steps breaks SMP/E and the product must be installed again

Re: Updated information to required PTFs for Rational COBOL Runtime for z/OS V6.0.1
As an addendum to my post yesterday.

In general, if the runtime is at the latest level 7.5.1.0 with the new ptf, then it will support 7.1.0.2 (as well as earlier versions) clients as well.

However, In one case, the catcher (ELACSV7) for remote calls from the latest 7.5.1.0 PTF (UK42740) will work differently unless the client EGL java runtime is also updated to 7.5.1.

In 7.1, EXTERNALLYDEFINED programs as well as EGL programs were called using CICS LINK, if parmform was COMMPTR

In V 7.5.1, EXTERNALLYDEFINED programs are called using CICS LINK, and EGL programs are called using CALL when parmform=COMMPTR. (the rationale is that now any exception thrown in the called egl programs can be sent all the way to the client).

To implement this, the v 7.5.1 client sends a new flag to the EGL catcher (ELACSV7) to indicate that the program being called is EXTERNALLYDEFINED. But if the client is v 7.1.0.2, no flag is sent. ELACSV7 assumes the program to be EGL by default, and so EXTERNALLY defined programs are not called with EXEC CICS LINK. The call is still successful, but it just uses a different mechanism.
