How can I increase the size of UI toolbars across Adobe Creative suite?

How can I increase the size of UI toolbars across Adobe Creative suite especially indesign, photoshop, illustrator on a new Apple retina display 2560 x 1140 with out changing/scaleing my screen resolution down?

While some applications let you change the font size of the UI (notably Photoshop in Interface Preferences), others do not yet (like InDesign).
You'll need to make your request using this form for it to be seen by the product manager(s):
Adobe - Feature Request/Bug Report Form
Make a good case because there are hundreds (thousands?) of things people request InDesign to do.

How to change redo log size in oracle 10g

Hi Experts,
Can anybody confirm how to change redo log size in oracle 10g?
Amit

Dear Amit,
You can enlarge the size of existing Online Redo log files, by adding new groups with different size of files (origlog$/mirrlog$) and then carefully droping the old groups with their associated inactive files.
Please refer SAP Note 309526 - Enlarging redo log files to perform the activity.
Steps to perform:
STEP-1. Analyze the exisiting situation and prepare an action plan.
A. You have to ensure that no more than one log switch per minute occurs during peak times.
It may also be necessary to increase the size of the online redo logs until they are large enough.
Too many log switches lead to too many checkpoints, which in turn lead to a high writing load in the I/O subsystem.
Use ST04 -> Additional Functions --> Display GV$-Views
There you can select
Gv$LOG_HISTORY --->for determing your existing LOG switching frequency.
GV$LOG -
> list the status(INACTIVE/CURRENT/ACTIVE) /size/sequence no. of existing online redolog files
GV$LOGFILE --- > list the information of existing online redolog files with their storage paths
You can document the existing situation of Online Redo Log Fiile management before going to enlarge Redo Log Files.
It will be helpful, if something goes wrong while performing activities.
B. Based on above Situation analysis, Plan your New Redo Log Group and there Members with new optimal size.
e.g.
Group No.         Redo Log File Locations u201C/oracle/<SID>/u201D                  Size
                             /origlogA                  /mirrlogA
15                        log_g15m1.dbf         log_g15m2.dbf               100 MB
17                        log_g17m1.dbf            log_g17m2.dbf               100 MB
                            /origlogB                    /mirrlogB
16                       log_g16m1.dbf          log_g16m2.dbf            100 MB
18                       log_g18m1.dbf            log_g18m2.dbf            100 MB

How can I increase font size on LR windows?

I would estimate the font size in my LR (and all Adobe windows) is a five. It's the same on all three of my computers, all of which are operating on Windows 8.
The last time I raised this issue, I was told to change the screen resolution -- pretty poor workaround considering all my other apps operate at the recommended screen resolution for the three computer and one additional monitors I use.
How can I increase the font size to make Adobe applications usable on my computers?

Hi,
I also use Win 8.1 and I have a high DPI 13" screen that is at 1920x1080 resolution and it is satisfactory although small.
LR (5.7 current) will not support screens with greater resolution unless you have razor sharp eyes.
We just need to hope that the next release (6) whenever it comes has native support for high DPI screens.

Hi all, iTunes streaming victims.
I struggled long with the streaming buffer problem of iTunes and indeed could solve it with increasing the buffer size, which features has been removed in iTunes 10. And this without updating the instructions by Apple!
Here is my solutions:

Thanks in advance.

How can I enable Enterprise Manager in Oracle 10g?

Hi,
We recently installed Oracle 10g on a MS Window server and after the installation which we created 2 instances each with a default schema from an existing data file (.dmp). After the installation, I realized that somehow, the DBConsole entry is missing in the Windows Services which then prevent me from being able to launch the new browser-based EM.
We thought we have picked all the components during the installation but for some reasons, it seems like the necessary files or configurations for EM was not there. So I was wondering if anyone know how I can manually install and configure EM?
Initially I thought if I go thru Oracle Universal installer and re-install everything again, it might help but I am concern that it will then wipe out the 2 instances and schemas that we have already created, especially since I have also applied the 10.2.0.3 patch already. So there was some discussions on calling the emctl program which when I tried, it I got error saying that ORACLE_SID not found. Then there was also some documentation on using the EMCA command to build the dbconsole, is that what I should do?
Lastly, I was under the impression that one will only setup one EM per server, which means in a perfect world, I will have one instance of the EM which will then allow me to manage the multiple instances (and their schemas) from the same console, is that correct? Or is one EM instance only manages one instance of the database? So if I have TESTDV & TESTUT configured on the same server, I will need to also create two EM consoles?
I am an amature and am more familiar with Oracle 9i which the EM seemed to be easier to use and setup. So I think I must have skipped or missed some steps during my 10g installation but am concerned that if I reinstall, I will lose everything.
Thank you very much.

First of all, thank you as always for taking the time...
I apologize in advance if I am not using the right terminology. Basically, I have only one Oracle Home directory on that server but I am able to create two different instances and in both cases, I have left the port number to be the same thinking that it's only one physical installation. I thought I would attach my TNSNAME and LISTNER ora files below to give you a better picture of my current setup.
So for me to connect to the database and the appropriate instance for example, like using SQL Developer, all I have to do is specify the Host Name to DBServer and then the Service Name to either TESTDV or TESTUT. Then I can connect to each of the instance directly.
But I only have one Oracle_Home directory and use the same port number as the default choice. So to your comment, if I only have one Oracle_HOME and one Port number, should I only install one EM instance?
Thanks much.
