After a long period of running, the DBA's may notice that your sequences are reaching maximum value:
SEQUENCE_OWNER |
SEQUENCE_NAME |
MIN_VALUE |
MAX_VALUE |
INCREMENT_BY |
C |
O |
CACHE_SIZE |
LAST_NUMBER |
AUTOMIC |
SQ_MQ1WP |
1 |
2147483647 |
1 |
Y |
N |
1000 |
2095940001 |
Release : ALL
Component : AUTOMATION ENGINE
If there have been no modifications, the sequence numbers will cycle back to the minimum (1) when reached. This can be confirmed by the CYCLE = Y above.
The only impact to the system would be if the MQ* table about to sequence has values that are 'stuck' near the threshold. Have your DBA confirm there are no MQ records for that table with a low primary key.
