我試過DB2中的一個巨大的插入查詢。 INSERT INTO MY_TABLE_COPY（SELECT * FROM MY_TABLE）;DB2日誌文件限制，SQLCODE：-964
在此之前，我設置如下：
UPDATE DATABASE CONFIGURATION FOR MY_DB USING LOGFILSIZ 70000;
UPDATE DATABASE CONFIGURATION FOR MY_DB USING LOGPRIMARY 50;
UPDATE DATABASE CONFIGURATION FOR MY_DB USING LOGSECOND 2;
db2stop force;
db2start;
，我得到這個錯誤：
DB21034E The command was processed as an SQL statement because it was not a
valid Command Line Processor command. During SQL processing it returned:
SQL0964C The transaction log for the database is full. SQLSTATE=57011
SQL0964C The transaction log for the database is full.
Explanation:
All space in the transaction log is being used.
If a circular log with secondary log files is being used, an
attempt has been made to allocate and use them. When the file
system has no more space, secondary logs cannot be used.
If an archive log is used, then the file system has not provided
space to contain a new log file.
The statement cannot be processed.
User Response:
Execute a COMMIT or ROLLBACK on receipt of this message (SQLCODE)
or retry the operation.
If the database is being updated by concurrent applications,
retry the operation. Log space may be freed up when another
application finishes a transaction.
Issue more frequent commit operations. If your transactions are
not committed, log space may be freed up when the transactions
are committed. When designing an application, consider when to
commit the update transactions to prevent a log full condition.
If deadlocks are occurring, check for them more frequently.
This can be done by decreasing the database configuration
parameter DLCHKTIME. This will cause deadlocks to be detected
and resolved sooner (by ROLLBACK) which will then free log
space.
If the condition occurs often, increase the database
configuration parameter to allow a larger log file. A larger log
file requires more space but reduces the need for applications to
retry the operation.
If installing the sample database, drop it and install the
sample database again.
sqlcode : -964
sqlstate : 57011
有什麼建議？
你爲什麼不使用DB/2實用程序來卸載/加載你的桌子嗎？實用程序不像使用簡單的INSERT語句那樣使用日誌。 UNLOAD/LOAD對於這類事情來說效率更高。請記住，在INSERT/SELECT操作過程中不能發出COMMITS - 這一切都必須作爲單個工作單元進行 - 對於大型表格，這可能會使日誌負荷過重。 – NealB
