Re: Oracle FM interpretation of locking behavior

Re: Reverse Engineering Triggers
Steve,
Here is a korn shell script I use. It also looks at
dba_trigger_cols. I was trying to do the same thing a
while back, but most of the scripts I found didn't
look at dba_trigger_cols. This view becomes important
if a trigger does something like 'before update of
on '. I will also use export
sometimes if the trigger is simple.

Re: Recovery scenario query
Sean, First of all, datafiles actually belong to a tablespace - not a schema. 1. You could place the tablespace into read-only mode, take a backup of the tablespaces datafile(s), then no additional backups are required for those datafile(s) (and you are assured that no one updates the data). 2. In general, to recover from media failure, you would have to restore the datafile from some backup, and apply all the archived redo logs since the backup.

Re: Oracle shadow process
If you are on Solaris, you may be interested in NOTE: 153655.1 SOLARIS: Determing Oracle Memory Usage on Solaris. CUT <<<<<<<< Many programs which display memory usage, like "top" or "ps -lf" do not distinguish between shared and private memory and show the SGA usage in each background and shadow process. Subsequently, it may appear as though Oracle is using several times more memory than what is actually installed on the system. To properly determine how much memory Oracle is using, you must use a tool which separates private and shared memory. One such tool is "/usr/proc/bin/pmap".

Re: STORAGE PARAMETER?
What version of Oracle? In 8i, instead of export/import, you use the following: alter table XXX move tablespace YYY storage (...); You will need to rebuild the indexes after executing this statement. I also don't think any dml is allowed during the move, but selects are allowed. Someone will correct me if I am wrong. For indexes, you can use: alter index XXX rebuild tablespace YYY storage (...) online; If I remember correctly, using the rebuild online option, dml is allowed against the table during the rebuild - Check the documentation.

Moving Oracle Binaries from HP to SUN
Has anyone done the following: Create a db using Oracle Loaded on an HP Server - The datafiles, controlfiles, etc will be on EMC Later, Install the oracle binaries on a SUN Server, basically unplug the HP from the SYMM, and plug in the SUN and bring up the database. I was asked this yesterday because some of the sun hardware is on back order, and they want to put the project in production before the parts will arrive. There is a spare HP server (bought for another project) they can use until the parts arrive. I am awaiting an official response from Oracle, but thought I would get your input.

Re: Moving Oracle Binaries from HP to SUN
Thanks for the responses. I thought exp/imp was the only way to go, but I feel much more confident now. That was also Oracle's response. BTW, I think they have changed their thinking on this issue anyway.

Re: Insert append generating redo
Stephane, I don't understand what you mean when you say you can select on t1 before any commit. I just tried this on an 8.1.7 database, and there was a signicant reduction in redo. There was only 668 bytes of redo generated vs. 2320 (see below). I think some redo will still be generated as you allocate extents (my tablespace is dictionary managed).

All of my production databases are still dictionary managed. I played around with locally managed tablespaces a while back on a test server, and when I ran a generic hot backup script, which attempted to dynamically put each tablespace in backup mode, it failed on the temporary tablespace. Of course all other tablespaces were successful (as you pointed out). Hopefully he would be doing this in a test environment first anyway, but I was just pointing out that he may want to test backup/recovery after converting.

RE: Unable to rebuild database from hot backup
Luckily I have never had this situation in production, and what I have read also suggests using the ascii file created from 'BACKUP CONTROLFILE TO TRACE' for recovery. I just had a little time on my hands and decided to give it a try. As I stated, I am by no means an expert in recovery (more like a novice), I was just stating what I observed. Maybe someone else will let us know their opinion. Thanks for your input. Rob Pegram --- "Jesse, Rich" <[EMAIL PROTECTED]> wrote: > Is this recovery method valid?
