Max currency in JDBC

Hello,

I have this error in my jdbc communication channel :

"Channel has reached maximum concurrency (5,000 concurrent messages) and no free resource found within 5,000 milliseconds; increase the maximum concurrency level"

Do i have to increase my maxiumum concurrency ? where can i find this option ? And what does it mean ? Or need to make space somewhere ?

Thanks by advance...

    if you are using pi 7.0 sp 12/ xi 3.0 sp 20

    You can specify how many messages the adapter is to process in parallel in a cluster node (default is 1)

    Maximum Concurency in the Receiver JDBC channel

    under processing tab of Receiver JDBC CC, You can set the level= 2 or more.

    If you are setting Maximum Concurrency to a greater value then even check out in the adavance mode Database Transaction Level as isolation level determines how transactions running in parallel can influence each other.
