CHC0289I

CHC0289I The DB2 Log Cache is starting with a range of first through last.

Explanation—The Db2® Log caches (Level 1 and Level 2) are reporting their contents. A range of LRSNs (log record sequence numbers) or RBAs (relative byte addresses) identify the Db2 Log records in the caches at the time of the report which can be when the log caches are started, when the log caches are ended, or during normal operations. To improve performance when using multiple subscriptions to replicate multiple streams of data at the same time, Db2 Log records can be retrieved from caches that are managed by CDC Replication.

Message Variables:

first—The LRSN or RBA value identifying the first Db2 Log record in the caches at the time of activation. As of Db2 version 11, the RBA and LRSN log positions have expanded from 6 bytes (twelve hexadecimal digits) to 10 bytes (twenty hexadecimal digits). CDC for Db2 for z/OS® version 10.2.1 and later will provide a limited RBA/LRSN value in the &SEQNO field in a manner that is consistent with previous database versions.

last—The LRSN or RBA value identifying the last Db2 Log record in the caches at the time of activation. As of Db2 version 11, the RBA and LRSN log positions have expanded from 6 bytes (twelve hexadecimal digits) to 10 bytes (twenty hexadecimal digits). CDC for Db2 for z/OS version 10.2.1 and later will provide a limited RBA/LRSN value in the &SEQNO field in a manner that is consistent with previous database versions.
