Whats the meaning when variables are enclosed by brackets
Hi,
Whats the meaning when variables are enclosed by brackets?
like say
lv_fieldname(25) TYPE c.
lv_fieldname = 'Material01'.
what does it mean by saying
ASSIGN (lv_fieldname) TO <fs_fieldname>.In many statement in ABAP, brackets mean that real "name" of operand (object) will be determined during runtime.
Normally you would write
data lv_fieldname(25) TYPE c VAUE 'SOME_FIELD'.
assign lv_fieldname to <fs>.
write: <fs>.
This code is static . It means that when syntax check takes place, compilator looks for definition of lv_fieldname.
It then assigns value of this field. The resuts is printintg on screen text "SOME_VALUE"
Now you have similar code, but with brackets
data: lv_fieldname(25) TYPE c VAUE 'SOME_FIELD',
some_field type i vlaue 5.
assign (lv_fieldname) to <fs>.
write: <fs>.
Here code is dynamic . It means that compilator doens't realy know the field name which will be assigned to <fs>.
We told him that this will be determined during runtime ( by means of brackets ) and the real field name we want to assing, is stored in LV_FIELDNAME.
This is equal to writing
assign ('SOME_FIELD') to <fs>.
When program starts, it is no LV_FIELDNAME which is assinged to <fs>, but the field which is stored in LV_FIELDNAME, namely 'SOME_FIELD'.
So the printed result will be 5 .
The same rule with dynamic operands applies i.e. in select statement
data: my_table(5) type c value 'SPFLI'.
select * from (my_table) ...
There is no table in DB named my_table , but compilator "knows" that we don't what to fetch data from MY_TABLE, but we want table name to be determined dynamically (during runtime). So, it is 'SPFLI' table which here will be taken into account.
One more note!
Such dynamic statements are generic (doesn't constitute fixed code) and open new range of possiblities.
Simple extending above example will create flexible (generic) program which can fetch data from different tables with one statement.
parameters: pa_tabname(40) type c.
select * from (pa_tabname) into ....
Of course here you need also dynamic internal table as target area, but this is of no importance here.
Hope this claryfies magic with brackets;)

ThanksUmmm, because it is ;)
However, if that isn't enough to convince you, just take a look at the description in the error message.
If that's not enough, then perhaps this demo might help (note database has 8K block size):
SQL> create tablespace small datafile 'c:\temp\small01.dbf' size 2M extent management local uniform size 1m;
Tablespace created.
SQL> create table t1 (id number) tablespace small;
Table created.
SQL> alter table t1 allocate extent;
alter table t1 allocate extent
ERROR at line 1:
ORA-01653: unable to extend table BOWIE.T1 by 128 in tablespace SMALL
Finally, what temporary tablespace are you referring to, where did the user state the version of Oracle, the type of tablespace they were using or the fact uniform sizes are being used ?
Therefore, your assumption that the "temp" tablespace has fixed extent sizes might not be correct ...

Whats the meaning of 'reaction' !
in a SAP standard code i found a systax like
if reaction = 'A' then ,........
Whats the meaning of this ?Well, basically, that is a conditional statement which is comparing the variable REACTION to the literal "A". REACTION is a variable of some type in the parameter, and if its value is = "A", then the program will do some lines of code.
This could mean anything within the context of the program, this variable could be used to evaluate a variable from a function module which the user is giving some answer via a button, or anything.

The time capsule though blinks amber and the Airport Utility shows blinking amber light and has a red circle with the number 1 in it.
There is an error.. probably trivial.. firmware update, default password..
Open the airport utility and find out what the error is.
Simply click the TC and see status in the summary page.. it will list all the errors and what you should do.. fix or ignore them. ie this TC has an error.. default password.. I chose to ignore.. when I "fix" the problem the LED goes green.
Here is additional TC.. it is blinking amber with faults.
Click the fault. eg default password.
You can ignore or edit .. if you click edit it will take you to the full setup where you can change the settings.
I ignored my errors and now it is green.. -

What the meaning of error occurred while iPad (-50)
Can anyone help me what the meaning of error occurred while restoring this iPad (-50)
Getting the same exact message. I updated to IOS 5 and every nothing was organized into the folders it took hours to build. I spent a ton of time cleaning ths mess up and I still get the the error "error occurred while restoring IPAD (-50). At this point, I would be happy to just stop the messages.
I am finding out about Apples support policies, which really suck! it seems like a disproportionate amount of people have this error after updating, yet there isn't a single thing about it on the Apple site and if I want to speak with someone, it will cost me money. Not a bad business strategy, I must say. -
my macbook pro started acting strange after a safari reset.
the mouse no longer: animates the dock, activates hot corners or selects pages from safari 'top sites' (without a hassle). attempts to reset dock and hot corners from preferences has been fruitless
the mouse also gets 'stuck' in logic precipitating force quits.
i run osX 10.6.8 on a 2007 macbook pro that has had 2 motherboards replaced autumn 2010.
my troubleshooting has been: restart, pRam and safe boot, also checking a 'test' account to find the same issues extant.
pRam restart caused airport to quit and say there is no airport card, and wouldn't respond untill another reboot.
macbook pro 15" 2.4 GHz intel core duo.2 GB 667 MHz DDR2 SDRAM.
i have treated this book with care, yet run logic pro studio to the limit of this book's abilities.
what shoud i do?You don't say which year you have, however...
...there are known problems with the mid-2010 models (see http://support.apple.com/kb/TS4088?viewlocale=en_US&locale=en_US) as well as early and late 15" 2011 models (see https://discussions.apple.com/thread/4766577?tstart=0).
Apple has taken ownership of the problems with the 2010 model but, unfortunately, the free logic board replacement for that model has probably long expired for you - three years after date of purchase.
One the 2011 models Apple has admitted no defect. You'll just have to skim the articles to get an overview of the problems that people are having (usually showing up as screen glitches at first and then going downhill from there).
Good luck,

==========Hi,
there has been an issue with an earlier set of bugfixes or an older CPU patch.
It did invalidate the catproc component.
Check: select comp_id,status, version from dba_registry;
if CATPROC is invalid, shutdown and startup your DB.
run
@?/rdbms/admin/catproc.sql
it can run between 10 and 25 minutes depending on horse powers.
Check again: select comp_id,status, version from dba_registry;
CATPROC should now be valid.
If yes run utlrp.sql again and your errors will be gone.
If not, your issue is something else.

And how are you spawning the php instances? I don't see that in the daemons array anywhere.
EDIT: It looks like the info in that page is no longer using pre-spawned instances, but lighttpd adaptive-spawn. The documentation has been made inconsistent it looks like.
You will note that with pre-spawned information, the config looks different[1].
You need to do one or the other, not both (eg. choose adaptive-spawn, or pre-spawn..not both).
