请教 ontape 命令backup的错误？

mentor

备份数据，使用命令

ontape -s

提示：

Achive failed - access sysmaster database (SQL:-229 ISAM:-131)

有没有人遇到过类似错误， 怎么解决？

查寻结果
-229        Could not open or create a temporary file.

The database server cannot create a temporary disk file. The file
should be created in the directory that the DBTEMP environment variable
specifies (or /tmp by default on UNIX systems). Check the accompanying
ISAM error code and look for operating-system error messages that
might give more information. Possibly your account does not have write
permission in that directory, or the disk is full. Since Version 5.01,
the INFORMIX-SE database server uses the DBTEMP environment variable,
but Informix Dynamic Server and INFORMIX-OnLine Dynamic Server do not.

On a UNIX system, try increasing the maximum number of open files
(NFILES parameter on some systems) to approximately 400.

-131        ISAM error: no free disk space.

Not enough contiguous free disk space is available to complete the
current operation. For C-ISAM programs, if transaction logging is in
use, roll back the current transaction. Make some disk space available,
and run the program again. For SQL products, roll back the current
transaction, if possible. Contact the system administrator about
acquiring more disk space for databases.

查看你的参数文件：TAPEDEV 的指向是不是硬盘上的一个文件，再看一下
这个文件所有的文件系统是否满掉了

mentor

TAPEDEV  /dev/rmt/0

硬盘空间只用了36%。并且在对某些表操作时，也是提示229错误。再请帮忙分析分析？

songdu

/tmp文件系统的空间够不够

mentor

/tmp 只用了1%， 还有5G空间呢

ifx

看看onstat -d，其中，在$ONCONFIG中配置的临时表空间和rootdbs是不是满了？

大梦

ontape备份是会用到临时数据库空间，请检查是不是空间小了~~~

建议只要有多余的磁盘空间可以为informix加多个临时数据库空间，并在$ONCONFIG的DBSPACETEMP中指定~~~
