Buffer Tuning

SIZE_DATA_BUFFERS = 262144 (256K, the default value for disk as I recall, unsure for tape).

I would increase NUMBER_DATA_BUFFERS to at least 256 and NUMBER_DATA_BUFFERS_RESTORE to 512.

There is a section of the performance tuning guide describing the memory requirement, please review it. If you see status 89 during backup you increased the buffers to much compared to the load on the master/media server.

thank you for your responses.. the error status that i always get for many clients are (13, 25, 41), so i increased the time out in the maters proprities, but i still have the same erros, when i verified i found that better to configure the files of Data_buffers, so when i read the docs about buffer tuning i didn't really understand what i've to do, and wich values i should enter... Please, i need to know the exact values i should put in the files, and what about the other files for disk backup ??

thanks for your intention and for your help

I cannot see how changing buffer sizes will fix 13, 25, 41 errors.

You need to troubleshoot each error separately.
This will include initial comms between master/media server and client(s), testing client(s) ability to generate data stream (test read speed from disk) and testing the network between client(s) and media server.

Logs needed to troubleshoot:

On media server: bpbrm and bpbrm

On client(s): bpcd and bpbkar

hi marianne,

thank you for your respons.

so, this is a random concern that affects customers SQL Policy. once it passes and the other not. communication is ok, no defect found. this is why I said it's better tuning Buffer files so that may be can be resolve the issue.

Buffer tuning will NOT help these error codes at all. These are purely networking issues.

In addition to the logs listed above that you need for troubleshooting, add dbclient to the list of logs on SQL clients.

You really need to troubleshoot each error separately.

hi,

ok thanks, i'll troubleshoot the errors and will give you a feedback.

thanks a lot for your your help
