Re: How to apply patch to Solaris for Intel
Dave, zip files can be handled on many platforms these days and I'd hope that Intel Solaris can process them if they're zipping system patches. Try which unzip to try to locate the executable or look for a man entry. I can unzip files on Sparc Solaris and AIX so I suspect you won't have a problem.

RE: deletion of data from a large table
Hi folks, Rick Cale was correct in saying that a truncate would release the storage by default. The only other option is to drop and recreate the table. Oracle will only release allocated storage when it is specifically asked to. The overhead on having a process monitoring which space it can drop would be prohibitive and needless. ( Imagine an example where an interface table is constantly filled and emptied - do you really want the storage to be constantly allocated and deallocated? ). Coalescing the tablespace will group adjacent free extents together but will have no effect on allocated blocks.

Re: Solaris 8 Question
Sam, you may find that you need to issue archive log stop and archive log start to force the database to start archiving again. Once it's failed to archive a log it seems to lose heart and give up until you nudge it. Ironically the ARCHIVER will keep writing to the alert log to say that it's still trying. But it isn't. No doubt it's a feature. I've seen this on AIX, HP, Solaris, you name it.

Re: How to execute Unix Command/program within a pl/sql block.
Hi,
you can't do this from PL/SQL but you can do it from Java and it's fairly easy
too. I'm not able to check the name of the class tht does it but armed with the
phrase java os command and either the Metalink or Ask Tom web site you

Hi

Thanks in advance.
-Seema
You can't. The nearest you can get is to write a daemon program which
waits for commands on a (dbms) pipe, executes them (popen(),
while(fgets()) {}, pclose() in C) and feeds the output back to the pipe.
Needless to say, it can be a serious security gap if you do not screen
the commands, since you are likely to execute them with the privileges
of the user under which the said program is run.
Many moons ago, there used to be something named 'flex' developed by
Oracle consultants and freely available on the web which was more or
less doing that. It may or may not still be around. I have had a look at
it after having developed my own (in Pro*Fortran and under VMS, nothing
stops me - no pipe, but a /OUTPUT=... was appended to the command and I
was reading and sending back the ouput file) and I can tell you that
Flex was unnecessarily complicated. To make simple seems very difficult
to many people.

RE: OFA (Optimal Flexible Architecture) in practice
Hi, If you can cd to a single directory and list all of your files then it means that all of your files are in a single filesystem probably (unless you've been VERY clever) sharing the same disks. I agree with the suggestion that you can create links to the datafiles from a central directory but that needs maintenance for each file added. If you have an OFA compliant structure then ls /u*/oradata/db_name1/*.dbf will give you the names of your datafiles.

Re: Speed up massive delete
Jack, First of all you could explore these options : Could you truncate the table ? Could you copy out the rows you want to keep (using CTAS NOLOGGING) /drop the table/rename 'kept-rows' table to original name? Are the rows in a partition that you could drop? If none of these are possible these measures will improve performance : Disable log archiving. Make sure your redo logs are on the fastest disk available. Consider allocating larger logs temporarily if you checkpoint frequently. Remove any unnecessary indexes. Oracle won't have to keep them updated PLUS the optimiser will be likely to scan the table (which is probably what you want) if there's no suitable index. Remove any unnecessary foreign keys and triggers. You may be advised to use NOLOGGING. Ignore this advice. NOLOGGING does not affect deletes and will make no difference.

Re: Fragmentation Locally Managed Tablespaces
Rachel, That maximum isn't a hard limit. Oracle themselves impose no limit of this kind. After you use all of the available space in the segment header block, any additional space map entries are overflowed into additional extent maps within the segment. This means that because the used extent information isn't cached in the data dictionary, queries against dba_extents etc. can cause many blocks to be read from LMTs if the map entries have overflowed in this manner. Therefore, the limitation is more of a recommendation to ensure that good performance is maintained.

Re: Speed up massive delete
Ron, I can see why it would save redo generation on direct load inserts. I can't understand why it would save any time on ordinary inserts, updates, deletes or import. I'm sure that your loads are direct loads and they make use of NOLOGGING/UNRECOVERABLE which is where you'll see the savings. Your original post mentioned that you are saving on your deletes also and I doubt that this is the case. Joe, Thanks, that's the same list that I usually produce at times like this.

If the index is created as unrecoverable then the redo log and archive log info is not written. That is where the time savings is derived from. During my daily load of my tables (approx 20 rows, 13 tables ,40 + indexes) the redo log generation and archivelog generation has decreased twice fold. Of course you should take a back up of your data and indexes after the work is completed. Time is saved during the IMP of the data also if the indexes are unrecoverable and or you EXP with index=N.

Re: OT RE: 24 x 7 on NT?
More on the same vein. Sorry if this thread is developing a me too feel. I'm happy to use GUI tools when they save me time. I know what they're doing and how they achieve their results. The availability of GUI tools is however a huge disincentive for new DBAs to find out how the database actually works and leads to a lack of understanding of the way the beast works as a whole. If your goal is to be a knowledgeable and effective DBA then you can't beat starting from the command line and working your way towards GUI when you find your feet. That requires a long-term viewpoint though, and the world is focussing increasingly on the short term. If I sound like a Luddite then I've given the wrong impression; that;s just my 4 groats-worth.

RE: License high water mark
Dave, I've never seen the license HWM cause a problem. It's usually informational in order for the DBA or auditors to tell if them have purchased sufficient licenses. Internal limit messages often indicate that a process is trying to exceed a user or system limit (memory/semaphores/file handles etc.). If your DB crashed you should look for any core or trace files that might have further info. You could also check that the instance has not left shared memory segments lying in RAM. EMN0 is a process which is used as part of Advanced Queueing to notify processes that a message has arrived. If you don't use AQ then you can ignore these messages. The alert log seems to show a perfectly normal shutdown. Is it possible that someone has accidentaly kicked off a backup?

RE: Quer
Hi, Oracle 8 datafile limits: The maximum number of files at Oracle 8 is OS dependant but usually it's 1022 per tablespace and 65533 per database. As with any program, the values of variables are held in control structures and it's up to the developer to arrive at sensible maximum limits for values in order to save memory and disk. That, in essence, is why Oracle has these limits. If the developers don't set limits then their code is less efficient as a result and that is a BAD THING tm.

RE: LOT (Little OT): Interesting Oracle related URL's.
Folks, Just my opinion but : Hosting a document on your site without the author's express or implied permission is bad. Providing a 'deep' link direct to a document within another site is OK if you check with the site owner. It's plain bad manners if you don't OK it first. Linking to the home page of the site containing the document is fine (unless, as mentioned, the link is along the lines of 'This bloke is a total arse and his paper is pitiful - here it is'). Another thing I hate to see is links to sites which pop the target site into a frame within the source site.

Re: PCTUSED??
Hi If the pattern of deleted dta leaves you with many almost empty leaf blocks then you may find that you would benefit from and index COALESCE rather than a REBUILD. On the subject of wasted space in table blocks it's very difficult to generalise. The best way to go may be to analyse the table immediately after the delete and see how the space is being used. You could then decide on appropriate table settings. It's possible to 'rebuild' a table by using ALTER TABLE MOVE . . . though it does have restrictions so is not universaly applicable. Would partitioning be an option for you? If you're dropping years of data at a time then you could drop a whole year's partition at a single stroke. It would be faster and would release the space immediately. Hope that some of that helps. I also hope you hadn't already thought of it all = ) Regards, Mike Hately Oracle DBA. Greg My concern is How can I reuse the deleted space, I have 20Gb Table with 15Gb Indexes, So I may not touch the table due to massiveness, I can do atleast indexes rebuild for availing 3-4Gb back. So in that regard pct_used has greater significance for reusing the space for future insertions. Thank you all for your responses and valueble input. Thanks Raghu.

I may consider my database is oltp. So how can decide a correct value for this??? PCT_USED might not have any effect for you at all. If you keep inserting rows by date, the blocks will fill with rows where the date is the same for every row in the block, or close. Then if the only time you delete is when you delete an entire year's worth of data, entire blocks will become empty. That's going to cause them to go on the free list no matter what you set PCT_USED to. As the other reply implied, your main concern may be tables where, after the mass deletes, there are many blocks below the high water mark that are completely empty. This would take up a little disk space until they are filled, but the main concern would be that full table scans would take as long after the deletes as before, due to the need to read all blocks up to the high water mark (empty or full).

Re: Messing with DB2
I'm having my first brush with it and it's a bit of a shift. Seeing as IBM now own Informix I'd expect them to rip off its features and incorporate them into DB2. First impressions are that it's easy to set up a default database but not as tunable as Oracle but having said that I'm at no great depth yet. It has some handy features but its core architecture doesn't seem as good as Oracle's. Anyway, it looks like it may be a contender in years to come. The latest version, 7.2 was scheduled for release this week. Given that the previous version is available for Linux and IBM are forging closer links with the Linux community I'll be amazed if Oracle don't release 9i for Linux fairly quickly. I'd have it next on the release schedule if I were in charge. Hopefully, I'll manage some sort of comparison paper of the 2 products when I get time and a little more production exposure to DB2.

Small files can leave you with lots of separate datafiles which isn't necessarily a drag on performance but can be an administrative chore and can cause more wasted space due to that pesky 'end-of-datafile' free extent. Mike, I will have to disagree with you about small files not necessarily being a drag on performance. Given a specific size of a database, it would be better to go in for larger files (avoiding the 2Gb pitfall if possible) since each datafile adds its own component to the flurry of I/O activity that takes place during log switch, i.e. when all datafile headers need to be updated. In simpler terms, (Large number of) Small datafiles + small redo logs + high DML activity = disaster during (the frequent) log switches... People who want to set up databases larger than a terabyte will inevitably have a budget to invest in new kit and buy-in to up to date OS and software levels. Not everyone has that luxury and a lot of legacy kit doesn't like 2GB+ files. That's only my opinion but really, why play around with any area that is demonstrably strewn with bugs unless you need to? Fully agreed!

RE: Auto Extend
Hi, Neither large files nor small files are evil. As with all things, fit the solution to the problem. Small files can leave you with lots of separate datafiles which isn't necessarily a drag on performance but can be an administrative chore and can cause more wasted space due to that pesky 'end-of-datafile' free extent. Large files can fall prey to inode contention and are less portable (discuss!). Files over 2GB are best avoided unless there is a compelling reason to use them or you are certain that all of your software can handle them. People who want to set up databases larger than a terabyte will inevitably have a budget to invest in new kit and buy-in to up to date OS and software levels. Not everyone has that luxury and a lot of legacy kit doesn't like 2GB+ files. That's only my opinion but really, why play around with any area that is demonstrably strewn with bugs unless you need to?

Re: how determine chaining if using gather_stats
Hi, GATHER_STATS only returns statistics that Oracle considers to be useful to the CBO. That doesn't include information on chained rows unfortunately.
