一生产AIX服务器上,DB2数据库需要备份,备份中报SQL2059W错误,具体信息如下:$db2backupdbhappydbonlineto/backupincludelogsSQL2059WAdevicefullwarningwasen

一生产AIX服务器上,DB2数据库需要备份,备份中报SQL2059W错误,具体信息如下:

$ db2 backup db happydb online to /backup include logs
SQL2059W  A device full warning was encountered on device "/backup".
Do you want to continue(c), terminate this device only(d), abort the utility(t) ? (c/d/t) t
SQL2001N  The utility was interrupted.  The output data may be incomplete.

这个错误提示一般跟操作系统关系较大,而非DB2数据库的错误。
1、检查文件系统是不是大文件系统,服务器空间,是否有limits限制;
2、检查目录所在的空间是否充足;

其一

1、查看活动的卷

# lsvg -o
rootvg

# lsvg -l rootvg
rootvg:
LV NAME             TYPE       LPs     PPs     PVs  LV STATE      MOUNT POINT
hd5                 boot       1       2       2    closed/syncd  N/A
hd6                 paging     24      48      2    open/syncd    N/A
hd8                 jfs2log    1       2       2    open/syncd    N/A
hd4                 jfs2       1       2       2    open/syncd    /
hd2                 jfs2       40      80      2    open/syncd    /usr
hd9var              jfs2       4       8       2    open/syncd    /var
hd3                 jfs2       8       16      2    open/syncd    /tmp
hd1                 jfs2       140     280     2    open/syncd    /home
hd10opt             jfs2       16      32      2    open/syncd    /opt
lg_dumplv           sysdump    8       8       1    open/syncd    N/A
paging00            paging     50      50      1    open/syncd    N/A
lv002               jfs2       248     496     2    open/syncd    /backup

"/backup"的文件系统为JFS2,是支持大文件系统的。对于JFS文件系统,在大多数实例中,多个文件系统使用大小配置为4 MB 的公用日志。例如,在初始安装后,根卷组中的所有文件系统将逻辑卷 hd8 用作公用 JFS 日志。缺省逻辑卷分区大小是 4 MB,缺省日志大小是一个分区,香港服务器,因此,网站空间,根卷组通常包含一个 4 MB 的 JFS 日志。当文件系统超过 2 GB 或使用单个日志的文件系统空间的总量超过 2 GB时,缺省日志大小可能不足。一般来说普通JFS支持的最大文件为2G;支持大文件的JFS为64G;JFS2支持的大文件为1T

2、检查/etc/security/limits文件中的参数,特别注意FSIZE的值。如果出现备份时出现SQL2059W错误,可以vi修改/etc/security/limits文件中的FSIZE的值为-1,注意此更改将在系统重新启动后生效。
default:
        fsize = -1
        core = 0
        cpu = -1
        data =-1
        rss = 65536
        stack = 65536
        nofiles =32768      #(-1是无限制)
        core_hard = 0
root:
nobody:
db2inst2:
        core = -1
        data = 491519
        stack = 32767
        rss = -1
        fsize = -1
        nofiles =10000
 

其二

1、查看ROOTVG有没有剩余可扩展的空间

When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

Can I install mysql on Windows 7 Can I install mysql on Windows 7 Apr 08, 2025 pm 03:21 PM

Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it.

Explain InnoDB Full-Text Search capabilities. Explain InnoDB Full-Text Search capabilities. Apr 02, 2025 pm 06:09 PM

InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

MySQL: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Explain different types of MySQL indexes (B-Tree, Hash, Full-text, Spatial). Apr 02, 2025 pm 07:05 PM

MySQL supports four index types: B-Tree, Hash, Full-text, and Spatial. 1.B-Tree index is suitable for equal value search, range query and sorting. 2. Hash index is suitable for equal value searches, but does not support range query and sorting. 3. Full-text index is used for full-text search and is suitable for processing large amounts of text data. 4. Spatial index is used for geospatial data query and is suitable for GIS applications.
