I serously need some help with my databases...
I have absolutly no idea what I am doing when it comes to databases. I have a website that has 9 different databases in it. I am having all sorts of problems and getting a lot of max_users errors.
This is what I have come up with...
Slow_queries 384
The number of queries that have taken more than long_query_time seconds.
Handler_read_rnd 20 k
The number of requests to read a row based on a fixed position. This is high if you are doing a lot of queries that require sorting of the result. You probably have a lot of queries that require MySQL to scan whole tables or you have joins that don't use keys properly.
Handler_read_rnd_next 689 M
The number of requests to read the next row in the data file. This is high if you are doing a lot of table scans. Generally this suggests that your tables are not properly indexed or that your queries are not written to take advantage of the indexes you have.
Created_tmp_disk_tables 297
The number of temporary tables on disk created automatically by the server while executing statements. If Created_tmp_disk_tables is big, you may want to increase the tmp_table_size value to cause temporary tables to be memory-based instead of disk-based.
Select_full_join 33
The number of joins that do not use indexes. If this value is not 0, you should carefully check the indexes of your tables.
Sort_merge_passes 612
The number of merge passes the sort algorithm has had to do. If this value is large, you should consider increasing the value of the sort_buffer_size system variable.
Opened_tables 711
The number of tables that have been opened. If opened tables is big, your table cache value is probably too small.
Table_locks_waited 765
The number of times that a table lock could not be acquired immediately and a wait was needed. If this is high, and you have performance problems, you should first optimize your queries, and then either split your table or tables or use replication.
I did not create these databases nor do I know what is needed to fix them. Please give as much detail as possible as what I need to do to get everything working properly.
My hosting company has been no help what-so-ever on this. I have no where else to turn.
Please, I beg of you pro's to help me!
