Reply with quote

Hi,
In changeman while promoting a package, I am getting Overlay warning for the same component present in another package. Can somebody please tell me why this warning comes and does that means it will overlay the changes present in other package? and if not then in which case the changes made in one package will effect the changes made for the same component in another package?

Sounds like a nice feature....
I'd guess that it is warning you that changes to your component could affect other components that also use your changed component.....
Which, of course, you had already verified and taken care of that possibility....grin....

Yeps, it does mean that the indicated component in your package(latest promoted one) will overlay changes present in any other package.

hi all... thanx for replies... i have just done some more testing and found that latest promoted component will only overlay the load module and not the contents of the same component in another package. hence the changes made in another package will remain intact just that it has to be demoted and promoted again.

Hello,

Quote:
will only overlay the load module
How might this be an only?

Possibly, there is something i do not understand, but if this were my situation, i'd be quite concerned that what i am trying to work with already exsits elsewhere and when i promote "mine" i've "de-moted" the other one. . . . Same would happen with the other is promoted.

Walking on load modules is usually (or causes) an emergency. . .

As i said, there may be something i do not understand. . .

Hi,

Sigh, well, only this information is right from what is posted so far

And let me little modify it..

Promotion are associated with packages, when some component is being promoted one has to supply the package 'number' as well. Change Man would issue a warning that another version of the component being promoted/check out exists within the target PDS, and will be overlaid if promotion/checkout is allowed. It is recommended that you investigate this situation and determine if this is really what is desired.

Latest promoted component will only overlay the load module in the respective change Man Package, which was supplied at the time of promotion, other package(s) has nothing to do in this.

Perhaps I don't understand what is being asked, might be if explained again, I would be of little help.

Hello,

Only means trivial in this case.

In my worlds, overlaying some load module by one that was not meant to replace it is quite serious.

My question was how can overlaying an existing load module be trivial. . .

Change Man checks if the 'same' load-module exist in Base-line, then it would IEBCOPY 'new' load-module onto older one. Other load-module remain intact.

If promotion is to be done in production, there is, usually, a process in place across different sites, whish states the severity of promotion; if it's to be done for some other LPAR, change-man still behaves the same way, IEBCOPY, but no 'usual' process is there, just promote the load-module. At my shop, we have an LPAR, which is replica of Production, to promote load-module to this LPAR, use the 'PROMOTE' option of Change Man & then run some 'refresh-job ' in that LPAR, your new-load module is bass-lined in that LPAR.

Ah..I hope, it was not confusing..
