Informix Error No More Extents

Looking at the results below I have the maximum number of allocated pages for table w_standard, as the table is not fragmented.

This way, you don’t reach the page limit anymore. navigate here

Convert the tblspace number to hexadecimal and extract its most-significant 2 digits (the high-order byte). This chunk number indicates where the table resides. 3. bshell6.1> Brendan Shine View Public Profile Find all posts by Brendan Shine « Previous Thread | Next Thread » Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) Because it used to have a maximum amount, and because that maximum was pretty low (if compared with other databases). http://www-01.ibm.com/support/docview.wss?uid=swg21395852

Variava por exemplo com a estrutura da tabela. The upper limit of extents per table depends on the page size of the dbspace it is in, as well as how much space is consumed by other entries on its In the resulting output, examine the value for "Number of pages used" or "Number of pages allocated". If nextns is small or the difference between npages and nused is less than the size of the next-extent size for the table, not enough disk space is available in the

After the table is created and loaded then run the dbschema output file. Check the module names for correctness. This is understandable as the max size of an extent is limited by the chunk size. Also, IDS can only track approximately 200 extents (logical grouping of disk pages) per table partition or fragment.

Can I have some help on this? If the dbspace you are loading data into had tables before it's quite possible that the free space within could be very fragmented. December 06, 2010 9:27 PM Fernando Nunes said... Note: A CREATE INDEX statement that does not specify IN TABLE as its storage clause creates indexes that store their pages in separate partitions from the data pages by default. 2.

If there was no space left, any INSERT would fail with error -136:-136 ISAM error: no more extents.After hitting this nasty situation there were several ways to solve it, but all check over here A resposta é simples. Desde a versão 9.40, por omissão os indíces são guardados em partição à parte. There's a real problem in this: If in these circumstances we create another chunk in the same dbspace, and after that our table requires another extent, the engine could reserve a

Compared to other databases that used to do the management in the catalog, they tend to hit issues in the SQL layer and at the same time these were slower. And the initial extent allocated is of size 2GB and next extent also is of size 2GB irrespective of the limits we have set earlier(40GB and 4GB).

I managed to compile and install the .so file, but failed to execute the function with error "9720: Module name or language name specified is not valid.".

  1. When this happens it will allocate a new page for the partition header that will be used for the extent list.

  3. Well, here is the deal - you have maxed out your pages (16 million is it).
  4. Comparada com outras bases de dados que faziam a gestão no catálogo, estas tendiam a encontrar problemas e constrangimentos próprios da camada de SQL, e ao mesmo tempo eram mais lentas.
  5. If this wasn't already done then Informix will automatically create one for you with the default size.
  6. Each partition in Informix has a partition header.
  7. Hi everybody, I have the problem with a few lists and the generated error is: "Fatal error : Error 1136 (bdb_errno 1136) on tfgld410105 in db_insert(51)" I need help with that...I

Even systems that have a maintenance window would suffer with this, because most of the time the problem was noticed during "regular" hours...So, I've been talking in the past... It reads: 2014-06-26 12:22:19 WARNING: partition 'testdb:informix.testtable': no more pages Text of the File $DBTEMP/$INFORMIXSERVER.alarm This message states exactly what has happened. I tried your sample using IDS 11.10 express edition on Fedora 7. You need JavaScript enabled to view it.

The most likely root cause will be that one or both these values have been realized. I think in total I had allocated no more than 75 extents. Chunk number 46 has allocated space for the index. weblink If you want to see all the details check the sysptnhdr table in $INFORMIXDIR/etc/sysmaster.sql.

The problem is that a single partition (ie table, index, table fragment, index fragment) cannot exceed 16,777,216 (2^24) pages on most platforms, including HPUX, IDS's page size is 2K so the You won't get that high number of extents because all the nice features that were always there (automatic extent concatenation, extent doubling...) are still there.

If nused is less than npages, and nextns is large (over 200), the table has too many extents. The most significant 2 digits is a0.

In order to explain that we must dive a bit deeper in the structure of a dbspace and tables. Note particularly the values reported for npages (disk pages available), nused (disk pages used), and nextns (number of extents).

If nused is less than npages, and nextns is large, the Simplesmente porque apesar de o Informix sempre ter feito um trabalho extraordinário na prevenção contra um elevado número de extents, nós tinhamos um limite, e era muito baixo. You may have to register before you can post: click the register link above to proceed.

Portanto, não havendo aí espaço livre todos os INSERTs falhariam com o erro -136:-136 ISAM error: no more extents.Depois de batermos nesta situação havia várias formas de a resolver, mas todas Simply because although Informix has done a pretty good job in preventing the number of extents to grow too much, we had a very low limit for the number of extents. Recreate the table in a dbspace with a larger page size. Quando tal acontece, se todas as páginas de dados estiverem cheias, o motor terá de reservar um novo extent para completar novos INSERTs.

Isto não era assim em versões anteriores. Transfering the table to a dbspace with a bigger page size Considering our above calculation, doubling the page size only means that the number of rows that can be inserted is Running onstat -t this corresponds to the > second to last row output. > > Tblspaces > n address flgs ucnt tblnum physaddr npages nused npdata > nrows nextns resident >
