db2

问题 I am writing a java application to read data from one table and writing it in some file. Our table have million of records, which we need to read daily and write in file. So, I am using Spring batch with reader as JdbcPagingItemReader, as I want to read records in pages. Below is my bean defination :- <bean id="pagingItemReader" class="org.springframework.batch.item.database.JdbcPagingItemReader" scope="step"> <property name="dataSource" ref="dataSource" /> <property name="queryProvider">

问题 DB2 allows user defined LBAC security policies. For creating the required labels and authorizations, I followed the steps provided here. So far so good. However, retrieving these policies is a big headache. Suppose, someone defined these policies and did not keep a backup of their activities. By looking at the defined components and labels, it seems to be quite hard to figure out what was done. The main problem I am facing is this: table syscat.securitylabelcomponentelements keeps a record of

问题 Environment: IBM Worklight 6.2, IBM Liberty 8.5.5.1, IBM DB2 10.5 & Windows 2008 standard Edition. For the High Availability of DB instance[WLDBINST], the following Architecture I have followed. 2 Windows Clustered Machines with IBM DB2 binary and SAN storage used to share the Database file in Common.

问题 We need to migrate a database from DB2 for i (iSeries AS/400) to DB2 Express. We do not have access to the iSeries, which is managed by a different company, so a direct ODBC/JDBC connection isn't an option. We need them to export their schemas and data into a format that we can import here. So far, they've sent us a set of field definition files (*.FDF), but I haven't been able to figure out how to do much with them (learning DB2 on the fly here). I've familiarized myself with db2move ,

问题 While a "Select All" feature in a select dropdown component would seem to be a straightforward feature, I've had an incredibly hard time finding a workable solution. I can find three SO questions on the topic, but none of the approaches work entirely. How to add a select all option to select component in CDE Pentaho CDE reset parameter How to add a "select all" option to select component in CDE? I have a table with a column that contains ratings from 1-5 (as string-type). I need to give users

问题 So I have been altering a table in QMF. After 3 alters I believe the table has gone into a pending reorg state so that I cannot alter it additionally. Am I correct in this assumption? If so what implications does this have and to get around it can I simply reorganize the table and continue altering it? If so, what does the syntax look like for reorganizing a table? I tried REORG TABLE PIDJBIP.TABLE_NAME_T and receive the error: an unexpected token "PIDJBIP" was found following "REORG TABLE".

问题 I am doing some changes on my table and I couldn't figure out the problem. This is my SQL script; ALTER TABLE X ALTER COLUMN X_ID RESTART WITH (SELECT MAX(X_ID) FROM X); Altough I used AS instead of WITH and tried other combinations, I couldn't find the exact syntax. (By the way, I cannot set this property in the initialization, I got to do it after creation of the table ) 回答1: When looking at the syntax for ALTER TABLE you will find that you can only use a constant, e.g., "RESTART WITH 12345

问题 I have three different databases for my different environments ( hsprd , hstst , hstrn ). hsprd is my production environment with live data. Every so often, a request comes through to restore production data to hstrn or hstst . I typically run this command (after stopping, then dropping the db): db2 restore db hsprd taken at 20140331180002 to /dbs into hstrn newlogpath /dbs/log/hstrn without rolling forward; When running this, I receive this message: SQL2537N Roll-forward is required

问题 I'm trying to connect my WEB server to AS400. The web server has not DB2 library neither ODBC library. I have installed XAMPP in my Windows computer, and one of my colleagues also did.
