dld.sl error

CHRIS QUINN — Fri, 16 Nov 2001 15:06:15 GMT

Hi,
has anyone had a similar problem to the following...

/usr/lib/dld.sl: Call to mmap() failed - TEXT /u02/oracle/testdb/8.1.7/javavm/admin/libjox8java_lang.sl
/usr/lib/dld.sl: Not enough space

The server is an l1000 with 2 gig of memory running 4 Oracle 11i instances.

</usr/lib/dld.sl: Not enough space>>

This happens if the application is running out of memory to allocate. Check the values of maxdsiz , maxssiz in your system.

kmtune -q maxdsiz
kmtune -q maxssiz

You would need to increase it if the values
are less. Also have a look at your swap.
(swapinfo -mt )

The server has 4 gig of swap and is paging frequently, more memory has been ordered to cure this....
The following are the results from vmtune and swapinfo...
# swapinfo -mt

Hi,

Please have a look at another thread "Out of memory error" by Vincent in this forum. It is there right on the front page of database forum. We discusses a similar issue.

Running 4 instances on a 2Gb box is a stretch. What you can try is:

Add another device swap and see whether that makes a difference. The swap size should be the same as the primary swap size.

Next, check with you dba whether they whether they can reduce SGA sizes to some extent.

If this doesn't work either, take a downtime and change the kernel parameters of maxdsiz, maxdsiz_64, maxssiz - double it from its current values; Also reduce your dbc_max_pct and dbc_min_pct to 10 and 5 respectively.
