Error description
You are using Tranaction Isolation. You have an application program defined as EXECKEY(USER) and Concurrency ( Threadsafe ). Following a call to the CICS/TCPIP Sockets TRUE, EZACIC01 (which is enabled as OPENAPI,) the program runs in basespace rather than in subspace . . Furthermore, when you use Debug Tool and RDz to debug this program , the debug session hangs. It was found that when Debut Tool program IBMPDSFU attempted to attach a subtask, that Attach failed with RC20 . It failed because at that time, control of the task was on an L8 TCB and the task was running in basespace . This causes the task to hang in a WAIT EXTERNAL out of IBMPDSFU because the attached subtask was going to post the task out of the wait.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: Userkey program ran in basespace when * * it should have run in subspace. * **************************************************************** * RECOMMENDATION: * **************************************************************** A program was running in SUBSPACE mode and made a call to an OPENAPI true. In this case, it caused DFHERM to issue an environment switch to BASESPACE which the TRUE ran in. The TRUE ran and returned to the application. However, no switch to the original environment of SUBSPACE occurred so the application continued in BASESPACE rather than SUBSPACE. Symptoms of this incorrect environment switching may present differently but in the reported problem, the application hung because it was unable to attach a subtask.
Problem conclusion
DFHERM has been modified to avoid the switch to BASESPACE in this case.
