Write I/O to the Transaction Log. Before a transaction is committed, it must be written to the transaction log. This can become a primary bottleneck. This can be lessened by isolating transaction logs. Data Compression. If there is available CPU and I/O is the bottleneck, consider data compression with the DB2 Storage Optimization feature.

Block on Log Disk Full(blk_log_dsk_ful): this configuration parameter can be set to prevent disk full errors from being generated when DB2 cannot create a new log file in the active log path. Instead, DB2 will attempt to create the log file every five minutes until it succeeds. After each attempt, DB2 will write a message to the administration
