Re: char(1) VS varchar2(1)
Hi! Trailing columns with NULL values do not occupy any space, not even a length byte. Yep, I missed this one. Also, when few trailing null columns aren't stored in a row, this particular rows column count is smaller as well, so the column count in physical table storage can vary... Non-trailing columns with NULL values have a constant value of 0xFF (255) in the length byte consuming just the one byte. Yep, and this means that even fixed-length CHAR datatypes don't consume any space except length byte if they contain nulls. I once saw a recommendation to store your data in char columns if you don't want to have to worry about row size changes and PCTFREE setting... which is mostly a stupid suggestion anyway and doesn't work in case of nulls either.

Antw: Question about datatypes
Hej Roland (Sverige?), I doubt that. If all the data is number in the varchar2 column, well, you don't need it to be varchar2. The easiest solution seems to be: INSERT INTO newtable SELECT TO_NUMBER(col) FROM oldtable; Premise: all your data in that column IS number. If you're not sure, do some pl/sql to identify the erroneous rows and track them in another table for correction purposes. hth, Guido [EMAIL PROTECTED] 03.11.2003 11.14 Uhr Hallo, Maybe this sounds simple for all of you, but I have a table with the field PRICE and that is with datatype varchar2 I want the data in that field to be inserted in another table with field PRICE, but that field has the datatype NUMBER.

If you had full control that rather suggests that they had provided you with an inappropriate username/password. If I log into a server as root using ssh, I don't consider that to be a flaw in ssh.

RE: connection using secureID tokens and JDBC thin
Rahul My understanding is that the JDBC thin client does not use Net8 across the network, but just connects directly to the listener. For example, on client systems that use thin client, I have not had to configure a tnsnames.ora. The way I understand secureID works, something on the client authenticates the connection to the server.

RE: Finding overlapping time periods - suggestions please
Mladen, Unfortunately, the density of your proposed option has warped the space continuum around us and made this option unusable... That and the fact I would have to take two years of University Mathematics to fully comprehend and appreciate the theory, makes this less than optimal in terms of time and space :-) ** Thanks to Stephane and Waleed. *** I will look into those approaches. Another approach that was suggested was to find all distinct intervals (a start time or end time), and then for EACH interval find the number of activities and calculate minutes accordingly. For example the data below, 1) the distinct intervals are 10:00-11:00, 11:00-11:30, 11:30-12:00, 12:00-13:00, 13:00-13:30, 13:30-16:00. 2) During the 10:00-11:00 (60 min) interval there was ONE task active, find the task and allocate 60 minutes elapsed and single minutes, 0 multiminutes 3) During the 11:00-11:30 interval there were 2 tasks active. Find each and allocate 30 elapsed minutes, 30 multi minutes, 15 prorated mutli minutes. 4) During the 11:30-12:00 intervaal there were 3 tasks active. Find each and allocate 30 elapsed minutes, 30 mutliminutes, 10 prorated mutli minutes. Etc. ActivityStart---End---Elapsed---ElapsedElapsed--Prorated--Prorated TimeTime--Minutes---Mutlitask--Single---Multi-Minutes MinutesMinutes--Minutes 1---10:00---12:00--120--060-60--2585 3---11:00---13:00--120--120--0--5555 4---11:30---13:30--120--090-30--4070 7---13:30---16:00--1500150---0---150 Babette -Original Message- Sent: 2003-11-01 11:59 AM To: Multiple recipients of list ORACLE-L Mladen, If you suggest a convoluted solution like this takes water when you have several million rows I fully agree :-). Funny enough, because it really looks like a purely relational problem, and yet it requires bending backwards. My feeling (and it definitely would deserve time to prove) is that quite possibly it's a design issue - perhaps the proper way would not be to say 'this activitity started then and ended then' but 'at this point in time that activity was running'; in fact, the convoluted part of what I suggest roughly means to do that, changing the design on the fly. SF Mladen Gogala wrote: Stephane, my solution was suggested because the client was a telco which was offering each client billing period of their own choosing (weekly, bi-weekly, monthly) starting whenever the client wanted. Finding which calls fall in the certain period was a major hassle. Of course, the solution like the one that I've suggested (and I don't know whether it would really work) would not make sense for 3 time periods altogether. What they've ended up implementing was a bunch of external procedures based on C and bitmaps, which is, accidentally, similar in concept to my solution. On 2003.11.01 08:09, Stephane Faroult wrote: [EMAIL PROTECTED] wrote: I was wondering if anyone had the need to find overlapping time periods and how to identify them efficiently. Here is the scenario: Elapsed minutes refer to the actual clock time either spent on a given task. Thus an activity that started at 9:00 am and finished at 11:00 am on the same day is said to have 120 elapsed minutes. If one task overlaps another (either completely or partially with another task), then the tasks are said to be multitasked. In that case the system will store the portion of the elapsed time that was multitasked as elapsed multitask minutes and the portion of the time that was not overlapped as elapsed single minutes. In addition, for the portion of time that two or more activities were simultaneously taking place; their time will be divided by the number of simultaneous activities and stored as prorated multi minutes. The sum of Elapsed Single Minutes and Prorated Minutes will equal the actual clock time that a vehicle was active. The following example should help to illustrate these concepts.

Hemant, I would guess that this is true if you are caching values for the sequence. Each database instance might cache the same set of values.

Trigger using TO_NUMBER function would be the first thing that comes to mind.
I have designs like that, which are used for parsing so calld Bloomberg
files. Those files contain strings like N.A., -,|| ('|' is the field
delimiter) and all of those strings mean NULL. Also, stock split ratio can
be described as: 1:2, 1/2, 2 for 1, 0.5, which has to be mapped to a

Re: Sequences in OPS/RAC
In the Oracle9i Real Application Clusters Administration manual, there is a chapter about sequence numbers generator. Before believing to the snake oil sellers, read the fine manual. Sequence numbers are guaranteed to be unique PER DATABASE. What they're not guaranteed is to come in ordered fashion. When sequence number are cached (that is the default), they're cached separately, for each instance. Each instance returns the contents of its cache, so it is possible for the smaller number being returned after a larger one. There is ORDERED flag to deal with that, but that can be extremely expensive and impose significant overhead on your cluster.

Re: Sequences in OPS/RAC
Sequences are mastered by the single SYS.SEQ$ table in each database. Cached or uncached, RAC or non-RAC, OPS or non-OPS, sequence numbers generated by this mechanism are unique across a database, not by instance. Each instance updates SEQ$ as individual numbers (noncached) or ranges of numbers (cached) are reserved, and those updates are controlled by the same synchronization mechanisms used by OPS/RAC for all UPDATE statements. This is precisely the reason that setting CACHE on sequence numbers help performance, as the number of updates to SEQ$ are reduced, minimizing the bottleneck. However, because of the simplicity of this caching mechanism, sequence numbers are not guaranteed to be in order (i.e. sequentially ascending) across multiple instances. Perhaps Mr. Stephens mis-spoke, confusing uniqueness for ordering? Or perhaps he is confusing distributed databases for clustered databases? I have always been comfortable with the idea that Sequences continue to guarantee uniqueness even in OPS / RAC environments. However, a recent Builder.Com article by Scott Stephens on the SYS_GUID function has these lines : Sequence generator numbers are guaranteed to be unique only for a single instance, which is unsuitable for use as a primary key in parallel or remote environments, where a sequence in each environment might generate the same number and result in conflicts. An identifier created by SYS_GUID is guaranteed to be unique for each database. Huh ?! Do the lines mean that a single sequence can have duplicate values in the two instances of an RAC cluster ?

So if you are upgrading IBM AIX 4.3.3 to AIX 5.1.0.0, you also have to upgrade Oracle at the same time. Oracle 9.2 CDs are separate for IBM AIX 4.3.3 and IBM AIX 5.1.0.0.

Re: Sequences in OPS/RAC
Yes, I've been aware of the difference between ORDERED and CACHED.
However, the Builder.Com article quite explicity asserts
Sequence generator numbers are guaranteed to be unique only for a single
instance, which is unsuitable for use as a primary key in parallel or
remote environments, where a sequence in each environment might generate
the same number and result in conflicts

As Tim has pointed out earlier, the author of the article might have confused
uniqueness with ordering.

New linux kernels (2.4.18 and later) have new memory management, which allows the kernel to grab more memory for buffers in periods of intense I./O activity. If you have a very active database on ReiserFS or Ext3, Linux is going to try to help you out by allocating more memory for the file system buffers, even by stealing! pages from the active processes, which will, in turn. start paging. The only possible response is to eliminate thebuffered I/ O and switch to non-buffered I/O. That is not so hard to do.

RE: Re[2]: Sequences in OPS/RAC
The problem is that the ORDER clause comes at the expense of CACHE. You can use SQL tracing to verify that each use of the sequence causes an update of SYS.SEQ$ when ORDER is set, effectively rendering the CACHE setting a no-op. So, especially in an OPS/RAC environment, the use of ORDERED sequences, especially heavily used ORDERED sequences, comes at a steep price. Think about it: is ORDERED *really* necessary? In some situations (i.e. check numbers), the ORDERED clause would be necessary, but unless you are pumping out thousands of checks an hour, perhaps a cached sequence shouldn't be used. But for system-generated keys, surrogate keys, etc, I don't think the semantics of ORDERED are necessary at all. Hi, I have RAC and I always use ORDER when I create SEQUENCE. The following information is from Oracle Manual: ORDER is necessary only to guarantee ordered generation if you are using Oracle with Real Application Clusters. If you are using exclusive mode, sequence numbers are always generated in order.

Process cannot "be swapping". When there is a serious shortage of memory, the swap demon(yes, your Unix box is haunted) known by the horrible name of [kswapd] writes the whole address space space belonging to the process onto swap. At that point, process is swapped.Unless, we are talking about the kswapd process, the process cannot "be swapping". Kernelswap demon seldomly uses oracle database.Process can be paging. When there is serious shortage of memory (but less serious then inthe first case), pages are stolen from the process and written onto the swap. It's called"page replacement". When processes need pages that have been thrown out of memory by the page replacement demon (in case of Linux, it's called bdflush but on some unix implementations,there is a process called "updated" or ! "paged " which performs this function.), it pages them in.If the page is in memory (buffer cache would a good place to look), we're talking about the soft page fault. If the page has to be read from the disk, we're talking about hard pagefault. Processes that page get charged for a lot of CPU time, all of it in the kernel mode.If you have gtop (my kindest advice is to get it), you can set preferences and see kernel modefor the processes.

New linux kernels (2.4.18 and later) have new memory management, which allows the kernel to grab more memory for buffers in periods of intense I./O activity. If you have a very active database on ReiserF! S or Ext3, Linux is going to try to help you out by allocating more memory for the file system buffers, even by stealing pages from the active processes, which will, in turn. start paging. The only possible response is to eliminate the buffered I/ O and switch to non-buffered I/O. That is not so hard to do.

RE: Re[2]: Sequences in OPS/RAC
All, Just wanted to point out that 'missing' invoice numbers caused by a variety of causes (even if they were not cached), can cause problems for Accounting/Finance Depts in certain countries. Basically, the Govt looks on this as being used for 'tax avoidance', unless proved otherwise. You *can* miss uncached sequences under certain conditions when the Db restarts or a short burst of SQL causes pressure on the DD cache... Had this occur once in an Apps database and had to apply patches to undo and put back the sequence...

You can use SQL tracing to verify that each use of the sequence causes an update of SYS.SEQ$ when ORDER is set, effectively rendering the CACHE setting a no-op. So, especially in an OPS/RAC environment, the use of ORDERED sequences, especially heavily used ORDERED sequences, comes at a steep price. Think about it: is ORDERED *really* necessary? In some situations (i.e. check numbers), the ORDERED clause would be necessary, but unless you are pumping out thousands of checks an hour, perhaps a cached sequence shouldn't be used. But for system-generated keys, surrogate keys, etc, I don't think the semantics of ORDERED are necessary at all. Hi, I have RAC and I always use ORDER when I create SEQUENCE. The following information is from Oracle Manual: ORDER is necessary only to guarantee ordered generation if you are using Oracle with Real Application Clusters. If you are using exclusive mode, sequence numbers are always generated in order.

Re: 10g new features
That's a nice article. The author could have enhanced it by adding or changing some wording. The buffer cache can be flushed with alter system flush buffer_cache. - ... instead of using the undocumented alter session set events = 'immediate trace name flush_cache' in 9i SQL: Regular Expressions (finally) - SQL: Regular Expressions; much enhanced over the less known owa_pattern (see http://www.stormloader.com/yonghuang/computer/OracleRegExp.html) Plus Oracle trace collection is deprecated (or gone?) after it's finally improved to the level of being quite useful (see http://www.dbazine.com/jlewis1.html) One of the biggest improvements to me is the datafile reuse across OSes.

[ORA-000060: Deadlock detected] Finding BOTH pieces of code that
I realize ORACLE-L could not be the best place to ask this question but (googling/metalink-ing did not help overly)... ORA-60 happens in our own application in the worst of possible places - at the customer's site. It happens intermittently. All I can do is look at the alert log for errors and follow the trail to the extremely verbose trace dumps and wonder. Clearly - I am over my head here as I have very little clue of what am I actually looking at. The question is how to interpret what trace dumps tries to tell (should I be scratching my head with it or is there some kind of magic behind TAR that would save the day)? For instance - what is the meaning of this trace snippet (coming from 8.1.7.x): Deadlock graph: -Blocker(s) -Waiter(s)- Resource Name process session holds waits process session holds waits TM-457a-24 37SX 17 14 SSX TM-4571-17 14 SSX 24 37 SX session 37: DID 0001-0018-0002 session 14: DID 0001-0011-0002 session 14: DID 0001-0011-0002 session 37: DID 0001-0018-0002 Rows waited on: Session 14: no row Session 37: no row On the assumption that the source of the above problem has nothing to do with INITTRANS/PCTFREE combo (as per metalink thread # 247579.999) but the culprit really is the broken app - what would be the 'proper' way to find which two pieces of code deadlocked each other? What comes to my mind ain't a pretty sight - turning on sql tracing on the database level (and suffering worsened performance), then once error happens finding out exact time from alert log, converting it to matching TIC number in 3 sec range (if I understand correctly Oracle will detect and break deadlock after 3 seconds). Once this range is known for 3 sec. window, digging through session traces would reveal what were other sessions doing at the time may be narrowing down the search to few possible sources of contention. Problem with this approach is way too much work to set up then 'dig' through all (tons of) trace files without any real guarantees source of deadlocking would be obvious after all this effort. So the question is - how to help duhveloper(s) by pointing closer to the 'root' of deadlocking?

RE: re Rebuilding Indexes in Oracle Apps -- an update
COALESCE would be a better option than REBUILD for Indexes on
monotonically increasing sequences where older values are purged periodically.
Unless you happen to be doing index_ffs on that particular index, in which
case a rebuild *may* be in order. Rebuilding the index may cause insert
performance problems for a time due to block splits.
If the index is a composite index with some other non-unique value(s)
making up the index, a higher than normal number of block splits may be
in your future. I haven't tested the composite index yet, but this seems reasonable.
If the index is based simply on the unique key, and for some reason you are
using index_ffs on it, then rebuilding will cut down the number of scanned blocks.
It would be interesting to see how skip scans are affected by this as well.

Henry -Original Message- Mladen Gogala Sent: Friday, October 31, 2003 6:09 PM To: Multiple recipients of list ORACLE-L Ron, it's not as stupid as you might think. Of course, you can use SQL to find all overlaping time periods, but for a large number of intervals, it's not going to be very efficient and it's going to take a very long time. In other words, it's not practical. Spatial option, on the other hand, uses special libraries and floating point to arrive to the target in a more optimal way. And yes, the reasoning is based on mathematics. On 2003.10.31 15:34, Ron Rogers wrote: Mladen, The information might be excellent for the lecture on the Space and Time Continuum but a black hole will destroy all theories of anything overlapping when they are on the same plain. Of course there has to be an guess work theory about where the stuff the black hole consumes ends up, and does it have the ability the grow at a rate proportional the the volume it consumes? Ron mª¿ªm [EMAIL PROTECTED] 10/31/03 02:54PM I have once been asked to suggest the solution for the same problem, and I have suggested a solution which was out of this world, but completely in line with my education of a mathematician. The project was scrapped and I didn't have an opportunity to apply the solution. To start describing the solution, let me remind you that overlapping areas of space would be discovered by using spatial option. To apply the spatial option, you need to define distance function. Temporal difference does satisfy the necessary conditions for a distance function, as far as mathematics is concerned. In mathematics, there is a structure called metric space, which is, basically, a set with a distance function. Distance function d (metric) on set S is a function d:S x S-R which satisfies the following two conditions: a) d(x,y)=0 for all x,y from S. b) d(x,z)=d(x,y)+d(y,z) for every x,y,z from S. (Cauchy inequality). Points in time, with the difference in seconds do satisfy the above conditions, which means that you can define geometry and use spatial option. Next lesson will be about Cauchy sequences, complete metric spaces, continuous functions, contractions and Banach theorem. If Cary got away with queuing theory, why wouldn't I get away with some abstract calculus and general topology? As I've said earlier, I've never actually had an opportunity to actually apply this solution, but it still looks quite elegant to me, despite it's apparent oddity. On 10/31/2003 01:24:37 PM, [EMAIL PROTECTED] wrote: I was wondering if anyone had the need to find overlapping time periods and how to identify them efficiently. Here is the scenario: Elapsed minutes refer to the actual clock time either spent on a given task. Thus an activity that started at 9:00 am and finished at 11:00 am on the same day is said to have 120 elapsed minutes. If one task overlaps another (either completely or partially with another task), then the tasks are said to be multitasked. In that case the system will store the portion of the elapsed time that was multitasked as elapsed multitask minutes and the portion of the time that was not overlapped as elapsed single minutes. In addition, for the portion of time that two or more activities were simultaneously taking place; their time will be divided by the number of simultaneous activities and stored as prorated multi minutes. The sum of Elapsed Single Minutes and Prorated Minutes will equal the actual clock time that a vehicle was active. The following example should help to illustrate these concepts. In the table below a list of fictitious activities for a vehicle are shown in addition to how the time is allocated to the various measures: ActivityStart Time End TimeElapsed Minutes Elapsed Multitask Minutes Elapsed Single Minutes Prorated Multi Minutes Prorated Minutes 1 10:00 12:00 120 60 60 25 85 3 11:00 13:00 120 120 0 55 55 4 11:30 13:30 120 90 30 40 70 7 13:30 16:00 150 0 150 0 150 Totals510 270 240 120 360 The vehicle was active from 10:00 to 16:00, a total of 6 hours (360 minutes) which is equal to the total of Prorated Minutes. The vehicle performed 8 ½ hours (510 minutes) of work during that 6-hour time span. This can be arrived at by adding the total of Elapsed Multitask Minutes (270) + the total of Elapsed Single Minutes (240).

Unicode: UTF-16 to UTF-8 conversion
Hi, I have a quick question that doesn't seem to be answered in the documentation. We have a database that has a database character set of WE8ISO8859P1 and a national character set of UTF-16. Currently we are not using any NCHAR, NVARCHAR2 or NCLOB columns, but would like to soon. However, we'd like to use UTF-8 instead of UTF-16. Since there should be no conversion necessary, is there any reason why I can't just alter the national character set to UTF-8? Or am I missing something? While we are on the subject, can anyone recommend for/against UTF-8 or UTF-16. I have read the pros and cons in the manual, but actual experiences could change my mind.

Of course, you can use SQL to find all overlaping time periods, but for a large number of intervals, it's not going to be very efficient and it's going to take a very long time. In other words, it's not practical. Spatial option, on the other hand, uses special libraries and floating point to arrive to the target in a more optimal way. And yes, the reasoning is based on mathematics.

Ron mª¿ªm [EMAIL PROTECTED] 10/31/03 02:54PM I have once been asked to suggest the solution for the same problem, and I have suggested a solution which was out of this world, but completely in line with my education of a mathematician. The project was scrapped and I didn't have an opportunity to apply the solution. To start describing the solution, let me remind you that overlapping areas of space would be discovered by using spatial option. To apply the spatial option, you need to define distance function. Temporal difference does satisfy the necessary conditions for a distance function, as far as mathematics is concerned. In mathematics, there is a structure called metric space, which is, basically, a set with a distance function. Distance function d (metric) on set S is a function d:S x S-R which satisfies the following two conditions: a) d(x,y)=0 for all x,y from S. b) d(x,z)=d(x,y)+d(y,z) for every x,y,z from S. (Cauchy inequality). Points in time, with the difference in seconds do satisfy the above conditions, which means that you can define geometry and use spatial option. Next lesson will be about Cauchy sequences, complete metric spaces, continuous functions, contractions and Banach theorem. If Cary got away with queuing theory, why wouldn't I get away with some abstract calculus and general topology? As I've said earlier, I've never actually had an opportunity to actually apply this solution, but it still looks quite elegant to me, despite it's apparent oddity.

Here is the scenario: Elapsed minutes refer to the actual clock time either spent on a given task. Thus an activity that started at 9:00 am and finished at 11:00 am on the same day is said to have 120 elapsed minutes. If one task overlaps another (either completely or partially with another task), then the tasks are said to be multitasked. In that case the system will store the portion of the elapsed time that was multitasked as elapsed multitask minutes and the portion of the time that was not overlapped as elapsed single minutes. In addition, for the portion of time that two or more activities were simultaneously taking place; their time will be divided by the number of simultaneous activities and stored as prorated multi minutes. The sum of Elapsed Single Minutes and Prorated Minutes will equal the actual clock time that a vehicle was active. The following example should help to illustrate these concepts. In the table below a list of fictitious activities for a vehicle are shown in addition to how the time is allocated to the various measures: Activity Start Time End Time Elapsed Minutes Elapsed Multitask Minutes Elapsed Single Minutes Prorated Multi Minutes Prorated Minutes 1 10:00 12:00 120 60 60 25 85 3 11:00 13:00 120 120 0 55 55 4 11:30 13:30 120 90 30 40 70 7 13:30 16:00 150 0 150 0 150 Totals 510 270 240 120 360 The vehicle was

RE: Unicode: UTF-16 to UTF-8 conversion
Alan, Unfortunately UTF-8 and UTF-16 is in fact different in their binary representations and hence you will have to perform a full fledged conversion to map the UTF-16 characters to their UTF-8 binary representation. You can use the dump() SQL function to see this for yourself if you have both an UTF-8 and UTF-16 database. Just store the same string data in both and dump the binary representation to see the difference. Additionally, if you try to just alter the character set you will receive an error back from Oracle that UTF-16 is not an _exact_ subset of UTF-8. The reason for the difference is that UTF-16 always uses 2 bytes for encoding Unicode but UTF-8 can use up to 3 bytes in the extreme case and hence use completely different encoding schemes to both support Unicode. I know this sounds confusing at times but Unicode is the standard and UTF-8 and UTF-16 are some of the encoding schemes implemented to support different versions of Unicode. Referring to your second question about UTF-8 vs. UTF-16, I would suggest UTF8 for both the national character set and the database character set in a mixed 9i and pre-9i environment. If using a pure 9i (in the ideal world!) environment then I would use AL16UTF16 for the national character set and AL32UTF8 for the database character set. The reason being that Oracle will only be supporting and extending these 2 Unicode encodings going forward and you may save yourself another database character set conversion in the near future. Another consideration would be the intensity of string manipulation in your application e.g. string searches, sub stringing, string lengths, etc. The more intense and frequent these operations are the more you would want to go with UTF-16 as this uses a fixed 2 bytes for encoding Unicode and is far more efficient at it than the variable byte length UTF-8 character set. Unfortunately you will have to load test your application to get accurate numbers but I have seen 30% longer response times on intense string manipulation operations (especially wildcard searches e.g. %DE%) after converting an Oracle 8.1.7 database from US7ASCII to UTF8. I know this is not comparing apples with apples, but gives and idea of what the extra byte and linked list/vector lookup can do to performance.

Re: 10g new features
How can *you* not get it? Gopal says in Oracle 9.2, 'alter tablespace rename' is possible. Of course. The full syntax is alter tablespace mytablespace rename datafile '/path/file.dbf' to '/path/newfile.dbf'. You see the three words 'alter', 'tablespace' and 'rename' in there? You'll get it in the morning. ihomo sapien/i think better during the day. Yong --- Jared Still [EMAIL PROTECTED] wrote: Not sure I get it either. :) The command listed on the 10g site that I referred to is this: alter tablespace ts_user rename to ts_user_01; Renaming a tablespace is apparently possible with 10g. Must be a joke here somewhere I'm missing. Jared On Mon, 2003-11-03 at 20:09, Yong Huang wrote: Gopal was joking about the fact that Jared only said 'alter tablespace rename' instead of ALTER TABLESPACE RENAME DATAFILE. In fact, 9.2 SQL Reference has this Moving and Renaming Tablespaces: Example This example moves and renames a datafile associated with the tbs_01 tablespace from 'diskb:tbs_f5.dat' to 'diska:tbs_f5.dat': If you only read the subtitle here (first line), you *will* be surprised.
