Example 8

Member CTETEVLT of the CA 1 or CA TLMS EARL data set hlq.CTAPEARL is for clients who also run the CA Tape Encryption product to identify if any tapes being sent off-site are not protected with encryption. CA Tape Encryption creates a unique BES Key Index for each new symmetric key instance. The BES Key Index is saved in the CA 1, CA TLMS, or IBM DFSMSrmm tape catalog record for each file that CA Tape Encryption encrypts through direct integration between the products. The EARL field BES_KEY, which is located in the common record, reports on the BES Key Index. If the BES_KEY field is not zero, the file is encrypted.

Report CTETEVLT uses this technique and checks the BES_KEY for each file in the tape catalog that is selected for movement off-site "today." If any of these are found to have a BES_KEY of zero, the report ends with an RC=8 to alert you that you may not be protecting all tapes that you intended.

Report CTETEVLT uses the new CTSEPM pattern masking capability to either include or exclude data sets matching specific name patterns. The pattern matching techniques used in the CTETEVLT EARL report provide a good example for exploiting this feature in user written EARL reports.
