Managing big mysqldump files
Hi List, We are facing a problem of managing mysqldump out put file which is currently of size 80 GB and it is growing daily by 2 - 3 GB, but we have a linux partition of only 90 GB.. Our backup process is first generate the mysqldump file of total database and then compress the dump file and remove the dump file. Is there any way to get compressed dump file instead of generating dump file and then compressing it later. Any ideas or suggestions please Thanks Anil

may be due to corrupted indexes it is taking long time. just re-org the table.if your table is InnoDB type then use below command to re-org it. mysql> alter table <> type=InnoDB; based on size of the table it may execute for long time . for us it has solved performance issue.

As noted in my original message, I need much more detailed info. The crux of the problem is that I need to run a query that could take several hours when it's using indexes correctly, but it is not working correctly so it takes longer than I've been willing to wait (about 14 hours). I need to make changes to indexes and run the query again, but I don't want to wait hours until I know whether the change was effective or not. I really need a way to find out how far the query has progressed after 15 minutes so I can calculate how much improvement the changes made.

RE: Restore help! been going 2 weeks
please check the my.cnf parameters with recommended values given in
my_huge.cnf file in support files.
to my knowledge For 2 GB RAM values you set are very high. I think system
is going for heavy swapping that might be the
reason it is going very slowly.

There really isn't enough information for me to answer without making some assumptions. So, I'll make those assumptions: 1) For all input rows with a given value of Tndr, you want to produce an output row of the form [lowest value] followed by a hyphen followed by [highest value] if more than one such input row exists 2) For all input rows with a *unique* value of Tndr, you want to produce an output row equal to the input row 3) In 1), 'lowest' and 'highest' can be done with the sql max() and min() functions -- this contradicts your example below, because you seem to be doing numeric comparisons relying on the meaning of alphanumeric text.

' giving problem while inserting in table.
Hi,
I am making a faq maintenance system using mysql and php.
To insert a entry in to a faq table i am using the following query:
-
INSERT INTO faq_table_netvd (id,question,
answer,netvcr,netdetector,add_date,mod_date,keyword,category,display,attach_
id)
VALUES ('0','$frm[question]',
'$frm[answer]','$frm[netvcr]','$frm[netdetector]','$frm[add_date]','$frm[mod
_date]','$frm[keyword]','$frm[category]','$frm[display]','$frm[attach_id]')
");
---
now the problem is when $frm[question] has some string like: "why i can't
eat".
i get the following error:
MySQL Error: You have an error in your SQL syntax near 't eat?' ,answer =
'Please recheck the power of your specs:)' ' at line 3.Putting a '\' before
' (e.g. \')solves my problem...but when i open the same quesion to edit it,
again i have to put backslashes where ever i find " ' " in the quesion or
answer.
Can anyone please suggest a solution to this.
thanx and regards
anil

A quick&dirty solution > though could be to just create a link: libmysqlclient.so.6.0-> > libmysqlclient.so.10.0 and see what happens from there :-) Nope, that's not true. You never need to recompile Apache if you are using PHP as a DSO (which we do in the OpenBSD ports tree). And don't symlink the shared library! Recompile to make it link against the right one. This is purely a mismatch of binary ports, I think. Update your ports tree and reinstall the ports from source, and everything will work fine. -- Anil Madhavapeddy, <[EMAIL PROTECTED]> - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
