* Internet Explorer 7.0 (WinXP)
12
Following browsers are not thorougly tested, but reported to work
13
* Safari 3.0.4 (MacOS 10.4.11, PowerPC G4)
14
* Safari (MacOS Tiger)

Following browsers are surelly not working:
23
- Clicking on buttons on the left side of image will open various
25
1) Various graphic options
26
2) Source of the data: database, data group, etc
27
3) Data export settings
28
- Mentioned above buttons may had special pictograms allowing fast
29
access to the encompassed options, allowing basic operations without
30
opening full controls.
33
- Holding left mouse key it is possible to select area. Afterwards the
34
selection area could be adjusted and shifted. Besides that it is possible
36
+ Only timeframe leaving the allowed value-range untouched. To achieve
37
that, please, select area with only a few pixels height.
38
+ Only accepted value range leaving the timeframe untouch. To achieve
39
that, please, slect area with only a few pixels width.
40
Following actions can be pefrormed with selection:
41
+) Zoom: by double clicking within the selction, or by clicking
42
on apply button attached to the selection.
43
+) Export: Export the data within selection using current export
44
settings. Achieved by clicking on export button attached to the
46
+) Cancel: To cancel selection just click with a mouse somethere
47
outside of the selection.
48
- By clicking on the graphic it is possible to get information about
49
data items displayed (and alter items mask: display only selected items
50
or remove selected items from display).
51
+ The mentioned information is shown in popup window which could be
52
moved and resized. If it's moved, the folowing clicks will alter
53
content in the window but not window position and size.
54
+ To enable again size and possition auto-adjustment the window
55
should be closed by clicking "close" button in the left-upper
57
+ The second button in the angle will maximize window.
58
- Changing certain parameters (for example items, non-by-item masks,
59
display window size) will automaticaly apply configuration. The rest
60
of the parameters should be manually applied.
61
- The graphic is pereodically auto-updated to display newly obtained
62
data (update rate is specified in the server configuration).
63
- The accuracy of the graph is highly dependent on amount of the data
64
items and may varry from 1 to appr. 100 pixels (actual values are
65
specified in the server configuration).
66
- Zooming time window in and out could be done with mouse wheel.
69
- The history is only updated if the graph (or some equivalent on other
70
pages) is changed. The alteration of EXPORT setting will be ignored by
71
history (but they will be reflected in the browser location).
76
In order to prevent problems with time, it is highly recommended:
77
a) Set CACHE MySQL to GMT timezone
82
* MSSQL (Microsoft SQL Server)
83
- The PDO(dblib) and mssql_* should not be used. The php driver is (5.2.4)
84
really ugly. It obtains whole result dataset in internal buffer.
85
- The PDO(ODBC) driver works correctly.
88
- ODBC have some problems as well (both PDO and odbc_* versions):
89
+ It crashes when executed using mod_php, but works from php_cli
90
+ While executed with php_cli, the php is hang on exit
91
this have been solved by
92
+ using apache 2.2.6, instead of 2.0.x
93
+ removing -fPIC compilation flag
94
+ compiling into the php only odbc, pdo and mysql DB modules
95
- Still there are in some circumstances quite strange behavior. The
96
'query' request could fail with error code '0' or just complaining what
97
it could not prepare SQL request.
98
+ This is a bug in PhP odbc(PDO/non-PDO) driver or in it interaction with
100
+ The problem looks to arise when a single connection tries to open
101
second result set (two parallel queries exists) to the database.
102
+ Please, note that the following would trigger a error:
104
$res = $odbc->Query();
106
and this not (since, in the first case connection closed after another is
110
$res = $odbc->Query();
112
+ The problem is handled in database.php by converting resultsets to the
113
arrays. We expect what all big queries are executed with Prepare.
118
To use multiple configurations with single code base, it is necesary to
119
enable "$SETUP_MULTI_MODE = true;" in the configuration.
120
Afterwards, it is possible to specify required setup with
121
a) '?setup=<setup_name>' - in the browser
122
b) 'php -- -setup <setup_name>' - in scripts
added
removed
