Re: Help...I am desparate
I suppose you could set the suid bit on mysqld binary. But that itself will be a security risk. I am not sure why your security folks are insisting on ports below 1024.

Re: Database slows down when mass users logging on
If you are knowledgeable about the application and know which tables are frequently accessed during the time of crash, you can send the create statements used to create those tables.

Re: Best way to store these data?
You did not say what these data would be used for. Will there be heavy reads? What is the time requirement for each query? Proper way to do this would be by having three different normalized tables. State: state_id PK state_name County: county_id (either abbreviate or create unique numeric id) county_name state_id FK Zip: zip_code PK county_id FK The above schema is normalized. But since portion of the data is static (state and county) it is possible to combine the first two tables into one table. However, the zip table needs to be in separate table unless you like updating records in multiple places. With proper indexing you can find a county name by a zip code with a simple where. It should be very fast. But still slower than one table solution. On 7/13/05, Laszlo Antal [EMAIL PROTECTED] wrote: Hi, I need to store all 50 states and there county + zip in mysql. What is the best way to do it? Should I just put them in to one table and use the states row for primary Id? or Put every state in separate table and use the zip row for primary Id?

Re: innodb crashes during heavy usage with exceeded memory error
You definitely should increase memory sizes in your my.cnf file. The settings that you have are for a very smal setup. You also need to allocate more space for innodb table extender. So instead of 10m have something like 50m or try and see which settings is better. The reason is under heavy load if innodb has to constantly extend the table space it will not have opportunity to anything else. So having 100m for each extend will reduce the number of times it has to increase table space. Are you doing any deletes/updates at the same time? You said 50m inserts to a table. Is that figure per day ? How large (in bytes) is an average row? Lastly look into the my.cnf for a large setup that ships with mysql. I think it is called my-large.cnf that will give you some help on settings.
