Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: SVC26 call is made under the QR TCB * * rather than the FO. * **************************************************************** * RECOMMENDATION: * **************************************************************** When issuing an EXEC CICS SET FILE OPEN request against a non-RLS file that is using dynamic allocation, a request to VSAM is necessary to get catalog information. This VSAM request is an SVC26 (locate) and is being done under the QR TCB. If VSAM takes a while to respond then CICS will appear to hang during that time as the QR awaits the response. VSAM calls should be done under the FO TCB.
Problem conclusion
DFHFCNO has been altered to ensure that the SVC26 call is made under the FO TCB.
