If several disk journals are offloaded to tape during a processing day, it is possible that run unit information might straddle multiple archive files. If an individual archive file is processed by CA IDMS Journal Analyzer, some run unit statistics may be lost. To avoid this situation, CA IDMS Journal Analyzer accepts concatenated archive files as input. The files must be concatenated in timewise sequence for proper processing.
In z/VSE environments, a user can execute the DITTO utility to concatenate multiple archive tapes, in lieu of a data management facility or another z/VSE utility program. One alternative is to use CAs concatenation utility (USJCNCT) to accomplish the concatenation task.
