A: trex bug

Thanks for your concern.
!)The mmc details you have provided is for 32bit win 2003. do you have any clue for 64 bit please
2)
We have an WEB AS Java only 7.0 SP14. There is a gateway instance installed too.
We wanted to install TREX 7.0 on our Windows Server 2003 x 64bit Windows. The installation ran without any errors. But the SAP MMC does not show any Instances at all. There is an error message saying:
MMC could not create the snap-in. The snap-in might not have been installed correctly.

TREX Patch Installation ERROR - DNS Domain Name

Dear all,
I have been facing a problem with a TREX Installation and I would like to request your help.
After successfully installing a portal (EP 7) and a TREX instance (7.00), I encountered the following error
while trying to install the TREX patch.
The Error that pops-up is the following:
"unknown message ID (osmod.hosts.getHostByAddress2) with parameter(s): -84.-230.-250.114".
This error appears when the installation reaches the 'DNS Domain Name' step.
The installation cannot procceed without resolving this issue.
I have been trying to install patch 49, which I have successfully installed in other TREX instances so there
should be no error with the binaries.
Has anyone come across a similar situation?
I would appreciate your input on the matter
Thanks in advance,
Kontogianni Eleni

Dear Eleni,
The issues that I have encountered where unrelated, otherwise I would have mentioned them for you as a clue
But what I was trying to say is that although sometimes prerequisites look OK there can be a bug or exception in the SAP coding that might cause this. Examples of these non-related issues are:
- https://service.sap.com/sap/support/notes/1114042
and
- when using the KM Portal Drive with a description that is "to long" connection is suddenly not possible.
I therefore advise you to open an OSS message @ SAP Support.
Cheers,
Benjamin

TREX ABAP Client: How to index file content?

Hello Colleagues,
We have installed TREX search engine and writing own solution by using ABAP Client. Everything is ok except files content like XLS, DOC and so on. When we try to post binary content to the FM TREX_EXT_INDEX it is not processed by TREX and only attributes search is available. I think something wrong with data types.
Test example:
data lt_data type table of char100.
data l_size type i.
data lt_doc type trext_index_docs.
data ls_doc type trexs_index_doc.
call function 'GUI_UPLOAD'
    exporting
      filename   = 'D:test.xls'
      filetype   = 'BIN'
    importing
      filelength = l_size
    tables
      data_tab   = lt_data.
ls_doc-doc_key = '00001'.
ls_doc-doc_langu = 'EN'.
ls_doc-doc_type = 'B'.
ls_doc-mime_type = 'application/excel'.
call function 'SCMS_BINARY_TO_STRING'
    exporting
      input_length = l_size
    importing
      text_buffer = ls_doc-content
    tables
      binary_tab   = lt_data.
append ls_doc to lt_doc.
call function 'TREX_EXT_INDEX'
    exporting
      i_index_id            = me->index_id
      i_rfc_destination     = me->rfc_dest
      i_index_document_list = lt_doc.
Document is indexed without content. Why?

Hi Evgeni,
I realise this is a little late, but just in case you are still interested - or anyone else out there is:
Basically somewhere internally the FM 'TREX_EXT_INDEX' does the following with your ls_doc-content:
l_xstring = p_content_in. "(p_content_in == ls_doc-content)
If you look at the conversion rules in ABAP the xstring then expects the string to contain only the characters '0-9A-F'. Which your string does not have after calling the FM SCMS_BINARY_TO_STRING.
Thus you have to format your ls_doc-content differently. Basically you need to move the hex characters in your xstring into 'real characters'. Which will expand the string massively.
We solved the problem using the following Form:
form conv_content using value(raw_content) type string
               changing content            type string.
data: lv_char   type c,
        lv_string type string.
field-symbols: type x.
clear content. " init output.
while raw_content is not initial.
    lv_char = raw_content(1).
    assign lv_char to casting.
    lv_string = .
    concatenate content lv_string into content in character mode respecting blanks.
    shift raw_content left.
endwhile.
endform.
Not exactly efficient, but you can call it just as you would call the FM SCMS_BINARY_TO_STRING (except you don't need the filesize). Then the TREX will index your MS-Office documents as long as they are not of type Office 2007 or newer. In that case there is another bug, where the mime_type you pass in the interface is only 50 Chars long - which is too short to fit the full docx mime type for example.

Robin

TREX indexing encrypted files

Hello,
In the context of an upgrade of e-recruiting (from 3.0 to 6.0) we installed a new Trex (release 7.10).
I recreated all indexes and I have problems with two files.
This files are uploaded by applicant and they are encrypted.
I have errors into the preprocessing because this files are encrypted.
In this moment I have two questions :
a) How can I index this two files ?
b) How can I decide into my ABAP server (e-recruiting) that I don't want to index this files ?
Thanks for your help
Dominique

Hi Paulo,
TREX indexes the file name and the content of the file for all files, including Excel files. I have come across several different issues with TREX not being able to index certain Excel files due to filter bugs. Check TREX 7.10 central Note 1021162 for a listing of the different revs.
Are you having issues trying to index a file? If so, what error are you getting?
Thanks!

Portal- TREX Server Error ?

Hello All
I am facing one strange issue.
I am working on portal Version: 7.00 SP9 and have TREX 7.
I have created the custom search options,component, and result sets.
Sometimes when I click on search button the J2EE server gets restarted automatically. What may be the reason ?
Also Basis team says that in portal server under tmp directory (Unix machine) lot of dump files are getting created. Is it due to TREX cache ?
Please help me resolve the issue.

Hi Vinod,
That at least sounds a bit like the known MemLeak problem when searching, see
https://service.sap.com/sap/support/notes/1047364 - "Memory: Java bug caused in large numbers of search results an out of memory."
The note is for KMC SPS 19 on NW04, but I expect that the same problem will be there on NW2004s / 7.0 with that old SPS 9.
So I would advise to upgrade your installation to the latest SPS.
Hope it helps

Solaris8 and 9 (possibly 7) /dev/poll driver bug report.

Hello,
I'd like to report a bug in the solaris 8 and 9 /dev/poll driver (poll(7d)).
As i do not have a support account with sun or anything like that, there
seems to be no other way to do that here (which is of course a very sad
thing).
Bug details:
The /dev/poll device provides an ioctl-request (DP_ISPOLLED) for checking
if a particular filedescriptor is currently in the set of monitored
filedescriptors for that particular /dev/poll fd set (open /dev/poll fd).
A quote from the documentation of the poll(7d) manual page taken from
Solaris9:
"DP_ISPOLLED ioctl allows you to query if a file descriptor is already in
the monitored set represented by fd. The fd field of the pollfd structure
indicates the file descriptor of interest. The DP_ISPOLLED ioctl returns 1
if the file descriptor is in the set. The events field contains the
currently polled events. The revents field contains 0. The ioctl returns 0
if the file descriptor is not in the set. The pollfd structure pointed by
pfd is not modified. The ioctl returns a -1 if the call fails."
It says that when you query for an filedescriptor which is currently being
monitored in the set, that it would return 1, and change the events field of
the pollfd structure to the events it's currently monitoring that fd for.
The revents field would be set to zero.
However the only thing which actually happens here, is that FD_ISPOLLED
returns 1 when the fd is in the set and 0 if not. When the fd is in the
set, when FD_ISPOLLED returns 1, the events field remains unmodified, but
the revents field gets changed.
A small sample code to illustrate:
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <sys/devpoll.h>
main() {
struct pollfd a;
int dp_fd = open("/dev/poll", O_WRONLY);
a.fd = 0; /* stdin */
a.events = POLLIN; /* we monitor for readability, POLLIN=1 */
a.revents = 0;
write(dp_fd, &a, sizeof(a));
a.fd = 0;
a.events = 34; /* filled in with bogus number to show malfunctioning */
a.revents = 0;
printf("DP_ISPOLLED returns: %d\n", ioctl(dp_fd, DP_ISPOLLED, &a));
printf("a.fd=%d, a.events=%hd, a.revents=%hd\n", a.fd, a.events,
a.revents);
According to the documentation of /dev/poll and namely DP_ISPOLLED this
program is supposed to print the following:
DP_ISPOLLED returns: 1
a.fd=0, a.events=1, a.revents=0
However it prints the following:
DP_ISPOLLED returns: 1
a.fd=0, a.events=34, a.revents=1
You can take any number instead of '34' and it will simply remain untouched
after the DP_ISPOLLED ioctl-request.
I hope it's clear now that the solaris8 and solaris9 (and probably solaris7
with /dev/poll patch too) DP_ISPOLLED implementation is broken.
This bug is also easily illustrated by looking at the solaris8 kernel sourcecode:
<snippet osnet_volume/usr/src/uts/common/io/devpoll.c:dpioctl()>
case DP_ISPOLLED:
pollfd_t pollfd;
polldat_t *pdp;
if (pollfd.fd < 0) {
mutex_exit(&pcp->pc_lock);
break;
pdp = pcache_lookup_fd(pcp, pollfd.fd);
if ((pdp != NULL) && (pdp->pd_fd == pollfd.fd) &&
(pdp->pd_fp != NULL)) {
pollfd.revents = pdp->pd_events;
if (copyout(&pollfd, (caddr_t)arg,
sizeof(pollfd_t))) {
mutex_exit(&pcp->pc_lock);
DP_REFRELE(dpep);
return (set_errno(EFAULT));
*rvalp = 1;
</snippet>
its' clearly visible that the code writes the current monitored events to
the revents field:
'pollfd.revents = pdp->pd_events;'
and that it doesnt set revents to zero.
It's funny to see that this has been like this since Solaris8 (possibly 7). That means nobody ever used DP_ISPOLLED that way or people were simply to lazy to file a bug report.
Another funny thing related to this. is that Hewlett-Packard did seem to know about this. Since HP-UX11i version 1.6 they also support /dev/poll. From their manual page i ll quote some sentences from their WARNING session:
"The ioctl(DP_ISPOLLED) system call also returns its result in the revents member of the pollfd structure, in order to be compatible with the implementation of the /dev/poll driver by some other vendors."
Hopefully this will get fixed.
I also like to reexpress my very negative feelings towards the fact that you're not able to file bug reports when you do not have a support contract. Ridiculous.
Thanks,
bighawk

Have I mentioned how much i love my playbook now Great job on os 2.0

[bdb bug]repeatly open and close db may cause memory leak

my test code is very simple :
char *filename = "xxx.db";
char *dbname = "xxx";
for( ; ;)
DB *dbp;
DB_TXN *txnp;
db_create(&dbp,dbenvp, 0);
dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
if(ret != 0)
printf("failed to open db:%s\n",db_strerror(ret));
return 0;
txnp->commit(txnp, 0);
dbp->close(dbp, DB_NOSYNC);
I try to run my test program for a long time opening and closing db repeatly, then use the PS command and find the RSS is increasing slowly:
ps -va
PID TTY STAT TIME MAJFL TRS DRS RSS %MEM COMMAND
1986 pts/0 S 0:00 466 588 4999 980 0.3 -bash
2615 pts/0 R 0:01 588 2 5141 2500 0.9 ./test
after a few minutes：
ps -va

2615 pts/0 R 30:02 689 2 156561 117892 46.2 ./test
I had read bdb's source code before, so i tried to debug it for about a week and found something like a bug:
If open a db with both filename and dbname, bdb will open a db handle for master db and a db handle for subdb,
both of the two handle will get an fileid by a internal api called __dbreg_get_id, however, just the subdb's id will be
return to bdb's log region by calling __dbreg_pop_id. It leads to a id leak if I tried to open and close the db
repeatly, as a result， __dbreg_add_dbentry will call realloc repeatly to enlarge the dbentry area, this seens to be
the reason for RSS increasing.
Is it not a BUG?
sorry for my pool english :)

I have tested my program using Oracle Berkeley DB release 4.8.26 and 4.7.25 in redhat 9.0 (Kernel 2.4.20-8smp on an i686) and AIX Version 5.
The problem is easy to be reproduced by calling the open method of db handle with both filename and dbname being specified and calling the close method.
My program is very simple:
#include <stdlib.h>
#include <stdio.h>
#include <sys/time.h>
#include "db.h"
int main(int argc, char * argv[])
int ret, count;
DB_ENV *dbenvp;
char * filename = "test.dbf";
char * dbname = "test";
db_env_create(&dbenvp, 0);
dbenvp->open(dbenvp, "/home/bdb/code/test/env",DB_CREATE|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_TXN|DB_INIT_MPOOL, 0);
for(count = 0 ; count < 10000000 ; count++)
DB *dbp;
DB_TXN *txnp;
db_create(&dbp,dbenvp, 0);
dbenvp->txn_begin(dbenvp, NULL, &txnp, 0);
ret = dbp->open(dbp, txnp, filename, dbname, DB_BTREE, DB_CREATE, 0);
if(ret != 0)
printf("failed to open db:%s\n",db_strerror(ret));
return 0;
txnp->commit(txnp, 0);
dbp->close(dbp, DB_NOSYNC);
dbenvp->close(dbenvp, 0);
return 0;
DB_CONFIG is like below:
set_cachesize 0 20000 0
set_flags db_auto_commit
set_flags db_txn_nosync
set_flags db_log_inmemory
set_lk_detect db_lock_minlocks

How to configure one TREX host with multiple index servers ?

Hi All,
Does anyone know how to configure TREX on the one host,
with multiple index servers ?
Reason for this is to make better use of resources available on the host server(4 Gig, 4 Processor, Windows2003), to improve the search performance of
our KM content for portal users.
I am using TREX 7 and have not been able to do this,
despite reading the Single and Distributed install
documentation.
Any help would be appreciated.
Regards,
Andres

Hi Andres,
To make use of the RAM a Server provides you have to run two indexserver processes (each can then consume 2 GB);
Proceed like this:
1. Go to TREXdeamon.ini; check if section [indexserver2] is there (it is already provided, but not active in standard installation)
2. In TREXdeamon.ini go to
[daemon]
references sections below
programs=nameserver,preprocessor1,indexserver1,queueserver,alertserver
and add indexserver2 here. Restart TREX; second porcess is then started; can be checked in TREX monitor in Portal as well
3. To distribute existing indexes to the new process, start TREXadmintool and go to Index: Landscape
Go to the last two columns and move the indexes (move master here/secondary mouse click)
If you don't distribute the indexes the new index server process will be regarded when an new index is created.
Hope this helps!
cheers

Multiple return values (Bug-ID 4222792)

I had exactly the same request for the same 3 reasons: strong type safety and code correctness verification at compile-time, code readability and ease of mantenance, performance.
Here is what Sun replied to me:
Autoboxing and varargs are provided as part of
JSRs 14 and 201
http://jcp.org/en/jsr/detail?id=14
http://jcp.org/en/jsr/detail?id=201
See also:
http://forum.java.sun.com/forum.jsp?forum=316
http://developer.java.sun.com/developer/earlyAccess/adding_generics/index.html
Multiple return values is covered by Bug-ID 4222792
Typically this is done by returning an array.
http://developer.java.sun.com/developer/bugParade/bugs/4222792.html
That's exactly the problem: we dynamically create instances of array objects that would better fit well within the operand stack without stressing the garbage collector with temporary Array object instances (and with their backing store: 2 separate allocations that need to be recycled when it is clearly a pollution that the operand stack would clean up more efficiently)
If you would like to engage in a discussion with the Java Language developers, the Generics forum would be a better place:
http://forum.java.sun.com/forum.jsp?forum=316
I know that (my report was already refering to the JSR for language extension) Generics is not what I was refering to (even if a generic could handle multiple return values, it would still be an allocated Object
instance to pack them, i.e. just less convenient than using a static class for type safety.
The most common case of multiple return values involve values that have known static datatypes and that should be checked with strong typesafety.
The simple case that involves returning two ints then will require at least two object instances and will not solve the garbage collection overhead.
Using a array of variable objects is exactly similar, except that it requires two instances for the components and one instance for the generic array container. Using extra method parameters with Integer, Byte, ... boxing objects is more efficient, but for now the only practical solution (which causes the least pollution in the VM allocator and garbage collector) is to use a custom class to store the return values in a single instance.
This is not natural, and needlessly complexifies many interfaces.
So to avoid this pollution, some solutions are used such as packing two ints into a long and returning a long, depacking the long after return (not quite clean but still much faster at run-time for methods that need to be used with high frequencies within the application. In some case, the only way to cut down the overhead is to inline methods within the caller code, and this does not help code maintenance by splitting the implementation into small methods (something that C++ can do very easily, both because it supports native types parameters by reference, and because it also supports inline methods).
Finally, suppose we don't want to use tricky code, difficult to maintain, then we'll have to use boxing Object types to allow passing arguments by reference. Shamely boxed native types cannot be allocated on the operand stack as local variables, so we need to instanciate these local variables before call, and we loose the capacity to track the cases where these local variables are not really initialized by an effective call to the method that will assign them. This does not help debugging, and is against the concept of a strongly typed language like Java should be:
Java makes lots of efforts to track uninitialized variables, but has no way to determine if an already instanciated Object instance refered in a local variable has effectively received an effective assignment because only the instanciation is kept. A typical code will then need to be written like this:
Integer a = null;
Integer b = null;
if (some condition) {
//call.method(a, b, 0, 1, "dummy input arg");
// the method is supposed to have assigned a value to a and b,
// but can't if a and b have not been instanciated, so we perform:
call.method(a = new Integer(), b = new Integer(), 0, 1, "dummy input
arg");
// we must suppose that the method has modified (not initialized!)
the value
// of a and b instances.
now.use(a.value(), b.value())
// are we sure here that a and b have received a value????
// the code may be detected at run-time (a null exception)
// or completely undetected (the method() above was called but it
// forgot to assign a value to its referenced objects a and b, in which
// case we are calling in fact: now.use(0, 0); with the default values
// or a and b, assigned when they were instanciated)
Very tricky... Hard to debug. It would be much simpler if we just used:
int a;
int b;
if (some condition) {
(a, b) = call.method(0, 1, "dummy input arg");
now.use(a, b);
The compiler would immediately detect the case where a and b are in fact not always initialized (possible use bere initialization), and the first invoked call.method() would not have to check if its arguments are not null, it would not compile if it forgets to return two values in some code path...
There's no need to provide extra boxing objects in the source as well as at run-time, and there's no stress added to the VM allocator or garbage collector simply because return values are only allocated on the perand stack by the caller, directly instanciated within the callee which MUST (checked at compile-time) create such instances by using the return statement to instanciate them, and the caller now just needs to use directly the variables which were referenced before call (here a and b). Clean and mean. And it allows strong typechecking as well (so this is a real help for programmers.
Note that the signature of the method() above is:
class call {
(int, int) method(int, int, String) { ... }
id est:
class "call", member name "method", member type "(IILjava.lang.string;)II"
This last signature means that the method can only be called by returning the value into a pair of variables of type int, or using the return value as a pair of actual arguments for another method call such as:
call.method(call.method("dummy input arg"), "other dummy input arg")
This is strongly typed and convenient to write and debug and very efficient at run-time...

Can anyone give me some real-world examples where
multiple return values aren't better captured in a
class that logically groups those values? I can of
course give hundreds of examples for why it's better
to capture method arguments as multiple values instead
of as one "logical object", but whenever I've hankered
for multiple return values, I end up rethinking my
strategy and rewriting my code to be better Object
Oriented.I'd personally say you're usually right. There's almost always a O-O way of avoiding the situation.
Sometimes though, you really do just want to return "two ints" from a function. There's no logical object you can think of to put them in. So you end up polluting the namespace:
public class MyUsefulClass {
public TwoInts calculateSomething(int a, int b, int c) {
public static class TwoInts {
    //now, do I use two public int fields here, making it
    //in essence a struct?
   //or do I make my two ints private & final, which
   //requires a constructor & two getters?
//and while I'm at it, is it worth implementing
//equals(), how about hashCode()? clone()?
//readResolve() ?
}The answer to most of the questions for something as simple as "TwoInts" is usually "no: its not worth implementing those methods", but I still have to think about them.
More to the point, the TwoInts class looks so ugly polluting the top level namespace like that, MyUsefulClass.TwoInts is public, that I don't think I've ever actually created that class. I always find some way to avoid it, even if the workaround is just as ugly.
For myself, I'd like to see some simple pass-by-value "Tuple" type. My fear is it'd be abused as a way for lazy programmers to avoid creating objects when they should have a logical type for readability & maintainability.
Anyone who has maintained code where someone has passed in all their arguments as (mutable!) Maps, Collections and/or Arrays and "returned" values by mutating those structures knows what a nightmare it can be. Which I suppose is an argument that cuts both ways: on the one hand you can say: "why add Tuples which would be another easy thing to abuse", on the other: "why not add Tuples, given Arrays and the Collections framework already allow bad programmers to produce unmainable mush. One more feature isn't going to make a difference either way".
Ho hum.

Bug? My events on the iPad iCal app aren't shown in the year view if they are more than two years in the future.

My events on the iPad iCal app aren't shown in the year view if they are more than two years in the future even though I can see them on the month, week and day view. Any suggestions on how to fix it? I've tried it all. I called the apple support and they checked on their iPads. They all did the same and they couldn't help me. They suggested trying this way. I'd like to be able to plan a few years ahead and the year view would make thing so easy!
Is this a bug?

Go to the Home screen and double click the Home button. That will reveal the row of recently used apps at the bottom of the screen. Tap and hold on the app in question until it wiggles and displays a minus sign. Tap the minus sign to actually quit the app. Then tap anywhere on the screen above that bottom row to return the screen to normal. Then restart the app and see if it works normally.
Then reboot your iPad. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider until the Apple logo appears. Let go of the buttons and let the iPad restart. See if that fixes your problem.

HT4528 My IPhone Bugged out/It is currently in the reset mode. I need to exchange all of my contacts from my Yahoo acct. to my new IPHONE. Can you please help me?

Hello ,
I purchased my IPHONE about 2 months ago. I am visiting family in DE & this tuesday it starting to go off & on by itself. Then the icons looked like they were floating . Then I could not call or text . The SIRI device would not work. Then it would shut down then the apple icon would reappear. I took it to a verizon dealer in Rehoboth DE & they said it BUGGED OUT/It is in a RESTORE MODE. It will not turn on. We could not transfer anny of my pics or contacts. I never even had a chance to back up the memory on ITUNES.
The tech @ Verizon said to contact APPLE to trouble shoot and try and transfer the contacts from my yahoo acct.
Can you please help?
Gina

set up your yahoo account in mail, contacts, calendars as an Exchange Account and you should be able to get your contacts from Yahoo from there.
