CONNX for VSAM provides two configuration parameters to expedite or disable the VSAM alternate index file import search process. The default settings for these parameters are optimal for the CONNX VSAM sample files and for the SCT VSAM master files. If your installation does not implement VSAM alternate index files, you can change these parameters to improve the CONNX VSAM file import response time.
The IMPORTALTINDEXES configuration parameter directs CONNX to execute or bypass the alternate index search logic for each imported VSAM file. When IMPORTALTINDEXES is enabled, CONNX searches the CICS RDO file for alternate index entries which point to each imported CICS file name. The default setting for IMPORTALTINDEXES increases CONNX VSAM file import response time in proportion to the number of RDO file entries.
