Enhance CDC z/OS to support Db2 z/OS RBA/LRSN values in full length (New JCF: COMMITSEQ/INTENTSEQ)

We plan to migrate existing SQL Replication CCD tables to CDC Live Audit tables.

For that we need to identify the exact values for the source RBA/LRSN log-points to keep the original sequence of DML and to identify the COMMIT scope of the transaction.

The currently provided Journal Control Fields (JCFs) &SEQNO and &CCID in CDC are cut. They only provide a 6-byte extract of the 10-byte RBA/LRSN. In a high-volume system, these values are not unique from a certain point in time.

In SQL Replication these values are represented in full 10-byte format in the columns IBMSNAP_INTENTSEQ and IBMSNAP_COMMITSEQ as VARCHAR(16) FOR BIT DATA.

We like to have the identical values and behavior in CDC JCFs as in SQL Replication.

COMMITSEQ should be the RBA/LRSN of the captured COMMIT of the source transaction, not the begin-of-UR as currently provided by &CCID.

We would like to have two new JCFs &INTENTSEQ and &COMMITSEQ with a datatype of VARCHAR(16) FOR BIT DATA that provide the full 10-byte RBA/LRSNs of each DML operation and COMMIT.
