support  syncToOSThread for J2C connections for CICS on Websphere Liberty for Z/OS

This idea is to get it on product roadmap after discussion with PM .Previous submitted idea : https://ideas.ibm.com/ideas/TWAS-I-255

Feature Summary

Social Security Administration (SSA )uses tWas 8.5 on Z/os and is migrating to Liberty with Identity assertion to CICS .

The feature ask from SSA to our internal dev team is to supportsyncToOSThreadfor J2C connections for CICS and not just db2 on Websphere Liberty for Z/OS.The currently use tWAS 8.5.x .

https://www.ibm.com/docs/en/was-liberty/zos?topic=zos-enabling-synctoosthread-j2c-connections.

Details based on customer conversations

Although there are alternatives that are possible via code changes ,SSA has explicitly told us this imposes a significant resource burden on the customer to change their connectivity from the Java application server to CICS and changes to asignificantly inventory of applications. SSA has a large mainframe footprint and they are currently doing a impact analysis on no of impacted applications .

If IBM accepts the requirement, then they have a migration path of least effort ensuring continued usage.I think that given there is no End of Support date for either release of tWAS, we could convince SSA to wait for Liberty to deliver the syncToOSThread support, even if it were 18-24 months out. Otherwise, as Judah (SSA customer) pointed out, they may be considering a total rewrite of the application in order to deploy it in a cloud environment (which probably wont be IBM Cloud) and will result in the loss of WAS/Liberty revenue on zOS at SSA. It might also wind up being a story told at conferences or published in journals highlighting their successful migration from z/OS to the Cloud.
