Problem summary
**************************************************************** * USERS AFFECTED: All users of IMS Database Reorganization * * Expert for z/OS Version 4 Release 1 * * (FMID=H25N410) * **************************************************************** * PROBLEM DESCRIPTION: Enhance the PIPEWAIT control statement * * to be able to specify different times * * to the wait state for opening and * * reading/writing. This is a forward fit * * APAR of IPR V3R2 PM02596. * **************************************************************** * RECOMMENDATION: Apply the maintenance for this APAR. * **************************************************************** Forward fit APAR of IPR V3R2 PM02596. The third parameter OPEN|RDWR to the PIPEWAIT control statement is added. If PIPEWAIT=(nn,i),OPEN is specified, the wait time in opening the pipe i is changed to nn minutes. If PIPEWAIT=(nn,i),RDWR is specified, the wait time in getting the pipe i block for reading/writing is changed to nn minutes. If the third parameter is not specified, both times are changed to nn minutes for the pipe i. Here, the pipe 1 is used between the unload task and the load task, and the pipe 2 is used between the load task and index builder task. This enhancement is being implemented for the FITS requirement MR0908093533.
