Increase maximum number of connections on DB2 database

Question

How do you increase the maximum number of concurrent connections on a DB2 database running on Windows? Are there any other considerations such as increasing the maximum number of locks?

Answer 1

Have a look at the Configuration Parameters Summary in the db2 documentation.

There are two levels of configuration: those that apply to every database (the top list, Database Manger Config), and those that are database specific (the bottom list).

At the database manager level you'll want to increase max_connections .

At the database level you'll want to increase max_appls .

You won't need to increase any lock parameter but you may need to look at increase things like applheapsz and appl_memory if those start to run low.

Hope this helps.
