Max Extents Error
Hi, I have a table which consists of Long Raw column in addition to other columnsof Number and Varchar2 datatypes. I have the datafile size set to 2GB. The average length of the messages goes up to 100M, sometimes more than that. I have now added three datafiles to that tablespace each greater than the first datafile. But I still keep getting the ORA-01631 Max extents reached for table "A" error. What do I do resolve this error? I am using 8K as the DB block size on SOlaris with Oracle 816. It is not a prod environment instead a dev environment. Thanks Sanjay

Oracle Installation on DiskArray
Hi, Thanks to those who replied. I was wondering whether which RAID level to implement. My database is not a very critical 24x7 database. It is a development database. There are going to be only a few users accessing this database. Infact the data as such is not very important as it is test data. Any suggestions on which RAID level to implement? TIA Sanjay

Re: Table Storage Estimates
Thanks all for the solution. I too thought of having a 1 : 1 relationship by separating the long raw column from the table. But I believe I am not permitted to do that (Strange). Since this is a third party product, I am not suppose to change any of the design issues and also the datatype. I believe row chaining is obvious in this situation. Also the average row length is 10M. The size of the database block size is 8. When I queried the dba_extents to find the number of blocks that have been occupied, it showed 16620 and the number of rows are 113. I am totally confused now. Any help greatly appreciated. Sanjay - Original Message - To: "Multiple recipients of list ORACLE-L" [EMAIL PROTECTED] Sent: Wednesday, February 28, 2001 12:46 AM Your estimate comes to around 1 row per block. What is the average row lenght once data is in the db ? Do you have row chaining ? What is your block size ? Can you increase it ? If a lot of queries do not need the long raw column you can put it in another table with a 1 to 1 relationship with the parent table. If your planning to have 200 rows of 1 block each, I do not understand why you are adding datafiles as the data should not occupied more than 3200K if you blocksize is 16K. Increase the size of the initial datafile instead of adding new ones. --- Sanjay Kumar [EMAIL PROTECTED] a crit : Hi, I have a table which has a structure similar to the following.

Document Preparation for a table
Hi, I am asked to prepare a document listing all possible suggestions for an effective tuningof a single table. The table has five to six columns with one column having a Long Raw datatype. The average row that gets into the database is about 1GB. Could anyone give me possible suggestions? I was planning to start from DB Block Size. I also thought of having 16 as the block size. I would like to know whether is this a good idea of having 16? Sanjay

User objects in System tablespace
Hi, I have a situation where in all the user related objects (tables) have been created in System tablespace. I believe there is no convention followed while creating these tables. Now, how do I separate these user related objects and put them in Users tablespace? Vinay
