75 ways to demystify DB2 #48: Techtip :Idle thread timeout after a select query in CLI applications connecting to DB2/zOS
A CLI based application can get Idle Thread timeout error if that application takes time to process the huge amount of data returned by a select query.
Until a COMMIT or ROLLBACK is being sent by the application after the query, the thread stays idle on the DB2/zOS server.
In order to prevent this issue, use commitOnEOF CLI Keyword. This keyword specifies whether an implicit COMMIT is issued immediately after receiving the last row from a result set.
By using this keyword, you can free resources as soon as the application receives the entire result set from a cursor and prevent hitting IdleThread Timeout error.
This keyword can be specified under [DSN] section in the db2cli.ini or added to the connection string in the application.
