64 Bit Version of MC
64 Bit Version of MC
When I am using a workspace with six months of 10-second Bars (three charts: BID, ASK and ASK of another symbol), I frequently get the error Message "Out of Memory".
My environment: MC 5.5, Forex, IB IDEALPRO.
I use Windows Vista 64 with 8 GB of RAM.
I understand that this is a limitation of MC 5.5 with its 32 bit implementation. Are there any plans to migrate MC to 64 bit to remove the 2 GB memory limit?
If so, when might the 64 bit version be released?

I have reduce the number of bars loaded in my charts, but since i use a lot of data series per chart via ADE as part of many multiple instruments strategy, i am running out of options.
Are there plans to start work on a 64bit version of MC ? If so when's the planned release ?
thanks

approx 150 charts.how many workspaces and charts do you load during a typical session?
how many indicators on the charts?
any large arrays?
I track a number of symbols and for each symbol a number of time frames.
I have indicators on each of these charts to store data via ADE.
Then on a number of strategies, refer to these data.

installation.
@ tj, when you installed MC, did you put in into the 32 or 64 bit program file folder? does that matter?

Re: installation.
32 bit version of MultiCharts is automatically installed in the 32 bit folder.@ tj, when you installed MC, did you put in into the 32 or 64 bit program file folder? does that matter?
64 bit version software is automatically installed in the 64 bit folder.
As a somewhat related question, is there a limit to the size of the MC database? My database is creeping towards 4GB and I'm always afraid that there's a size limit to the 32-bit implementation of MC.
Further, is there an utility that periodically compresses the MC database? I've noticed that whenever I delete data/symbols or clear caches from QM, the database folder size doesn't get reduced (even after tsServer.exe closes).

Dear Sirs,
It is hard to say, when the 64 bit version of MultiCharts will be released. However, it won't be done in MC 6.0 and 7.0 for sure.
Regarding the database size limitation, there is a limitation of 4GB, which has nothing to do with 32 bits. It is a firebird database limitation.
Please come to our Live Chat so we can connect to your PC remotely and do it for you.

This is the normal database behavior. To clean the database, special utilities should be used.Further, is there an utility that periodically compresses the MC database?

I am quite surprised by your answer, as Andrew stated "We never came to limits of our databases but 7Gb ones worked perfectly." on Friday June 18th in the following thread:
http://forum.tssupport.com/viewtopic.php?t=7500&start=0
So, which answer stands?
Regards,
Thierry

Why must we connect via live chat for you guys to "clean" the database ?Dear Sirs,

Why can't you guys either put up instructions or release a utility for us to manage it ourselves ?
thanks
Good question. I'm sure some of us have managed databases before. I've managed Oracle on HP-Unix, DB2 on IBM Mainframes, RDB on OpenVMS and SQL on Windows. So, I think I can handle it if given the right instructions and proceduresWhy must we connect via live chat for you guys to "clean" the database ?

Dear Sirs,
To reduce the database size you should do the following:
1) extract two files from the zip-folder and copy them into the directory, where MultiCharts is installed, normally it is "C:\Program Files\TS Support\MultiCharts\"
(to know the directory, where MultiCharts is installed, right click on icon MC->Properties->Start in)
2) Close QuoteManager and MC
3) Run the gbak.bat file
4) Rename TSstorage.gdb to TSstorage_old.gdb_old and TSstorage_New.gdb to TSstorage.gdb in "%allusersprofile%\Application Data\TS Support\MultiCharts\Databases\"

Re: 64 Bit Version of MC
Dave, just to confirm, above you say that the database should work even if larger than 4GB, true?
Does this mean that the gbak process reduces the database size but isn't strictly required?
What does the gbak process remove?
Thanks!

Re: 64 Bit Version of MC
jek,
Databases can be larger than 4GB, some users have such databases but we have not tested such configuration. If you delete symbols and/or data from the Quote Manager, the actual size of the database remains the same. Gbak removes this already deleted data from the database reducing its size.

Re: 64 Bit Version of MC
Is there also a version of the Gbak script for MCDT?If you delete symbols and/or data from the Quote Manager, the actual size of the database remains the same. Gbak removes this already deleted data from the database reducing its size.
Executing the script in "C:\Program Files\MultiCharts Discretionary Trader\" leaves the database in "C:\ProgramData\TS Support\MultiCharts Discretionary Trader\Databases\" untouched but does change the database in "C:\ProgramData\TS Support\MultiCharts\Databases\".
