CECJ0009E (0x01240009) CECJ0009E Error accessing target log stream log-stream-name for subscription subscription-name attempting to locate block x'system-clock-value' - GMT time DB2-timestamp. The error message code is specific-return-code, with the specific return codes (rc1, rc2).

Explanation
During start of replication, the target server encountered an error accessing the target log stream 
to determine the correct restart timestamp for a subscription.

The contents of the message include the block header timestamp (in hexadecimal format and converted to a DB2 
timestamp) that was being searched for when the error was reported. Also included is the specific return code
reported by the API used to access the target log stream and the return and reason codes values from the failing IXGBRWSE request.

Start of replication fails for the subscription.

User response
The bookmark is inconsistent with the contents of the target log stream. Use the IXGBRWSE return and reason 
codes to assist in determining why the target log stream cannot be accessed.

You need to determine where processing should restart for the subscription and issue a SETLOGPOS command to 
set a new bookmark location before attempting to restart replication for the subscription.

Before restarting replication, resolve any issues with the target log stream that would cause replication to 
fail when trying to write data to the log stream.
