I do not have any war files, I just downloaded 7.4 zar file, extracted it and installed. Nothing else I have done. Currently I'm facing issue with the My support portal. Can I get it in any other way and also tell me how can I deploy war file to server. Please explain in detail. Thanks.
Unfortunately, we do not have information clearly saying this.
But as you noticed in the PRPC 7.4 by default the prsysmgmt.war is not deployed. Moreover, in 7.4 we introduce the flag like isPegaCloud in case of cloud env will not display this URL, and this has been introduced in HFix-44169.
Of course, you can rise an media request and provide the business justification and ask for the prsysmgmt.war as well. But, in PRPC7.4 we are strongly recommended to use Designer Studio instead of SMA. And as I said in case of any bugs in SMA, we will not provide a fix as we did before.
That's why I would like to also encourage you to use start using the Designer Studio. As we are going to drop the support for SMA.
