HEllo,

we have MAXDB 7.6.06.009 on Linux RHEL 4 . Backup (inrcemental and full) suddenly stopped working,

External backup log:

2010-08-03 10:00:18 The database has finished work on the request.

Receiving a reply from the database kernel.

Got the following reply from db-kernel:

SQL-Code :-903

and knldiag.err says:

2010-08-03 13:20:36 16158 ERR 11000 d0_aopen Error during creating semaphore, resource problem

Have you seen this? Do you have any recommendation for database or Linux parameters?

Thank you

You have to increase the max file descriptors in /etc/sysctl.conf and you have to make sure the used shells for the user running the database software are adapted also.

See

http://www.cyberciti.biz/faq/linux-increase-the-maximum-number-of-open-files/

and also check

ulimit -a

for the user running the database software.

Hello Markus,

thanks for your answer. I've changed parameters but I have to wait for DB restart to Sunday.

Hello,

now I have other problem,

ERR 51080 SYSERROR -9407 unexpected error

ERR 3 Backup Data backup failed

ERR 3 IOMan + An error occurred while accessing a volume,VOLUME_TYPE=data,VOLUME_ID=22,BLOCK_NO=1776647,NUMBER=2,ERRORTEXT=e

ERR 3 IOMan + nd of file,NUMBER1=189

ERR 17 SrvTasks + Servertask Info: because Error in backup task occured

ERR 10 SrvTasks + Job 61 (Backup / Restore Volume Task) [executing] WaitingT832 Result=6433

ERR 6 KernelCo + Error in backup task occured, Error code 6433 "system_error"

DB is running, no other errors, only during backup. Every backups has error in another data volume.

Regards

Petr
