If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Prompt customer need to reduce prune interval

In a busy Q Rep env with many bi-di Q subs, there may lots of P2PNORECAPTURE signal insert into IBMQREP_SIGNAL control table by Q Apply program.

As per design, Q Capture delete up to 10000 rows at a time for one prune interval.

When the average P2PNORECAPTURE insert speed faster than Q Capture house keeper cleanning speed, IBMQREP_SIGNAL table may growing very big.

Although we know reduce the parameter of prune_interval could help to solve the issue, customer think it will be helpful to get a message if this situation appears with a hint to reduce the pruning interval, like print a warning message to prompt customer that they may take a consideration to reduce the prune interval, otherwise data may accumlated and signal table will grow big
