[orientdb] 3rd parameter in pyorient query() function.

In pyorient documentation query() function has 3 parameters: result = client.query("select from my_class", 10, '*:0') - 1st is the query. - 2nd is the LIMIT. In this case: LIMIT 10. - 3rd? What is the 3rd parameter? -- --- You received this message because you are subscribed

I guess that is good news for Erik. The job description sounded more like a community manager than a driver developer. Are you looking for both? Scott -- --- You received this message because you are subscribed to the Google Groups "OrientDB" group. To unsubscribe from this group and stop

Hi Luca, I'm sorry, that was an error on my part: I changed that after the crash, before the crash it was on a very low setting, around 400. I'll change it back anyway! Erik > On 08 Apr 2016, at 20:10, Luca Garulli wrote: > > Hi Erik, > Do you have 2GB of RAM on that

Re: [orientdb] Re: Today, our OrientDB crashed without any errors.

Hi Erik, It's hard to give you an answer here, this is the first report we have from a system that crashes without emitting any logs at all. In other cases, when we had an unexpected crash with few information, it was because of some OS related procedures (eg. process kill under heavy load), but

Re: [orientdb] Re: Today, our OrientDB crashed without any errors.

Hi Erik, If OrientDB dies with no log, it means the OS killed it. The most common reason is the out of memory. Look at: http://stackoverflow.com/questions/726690/who-killed-my-process-and-why A few questions for you: - How much physical RAM do you have on that server and - How much is

Re: [orientdb] Re: Today, our OrientDB crashed without any errors.

Hi Erik, Do you have 2GB of RAM on that server? if this is the case, you cannot have 8GB of RAM for the Diskcache: -Dstorage.diskCache.bufferSize=8192 So this must be the reason. This is the formula: diskcache + heap < available ram So with 1,5GB of free RAM, try these settings:

Hi Luca, Thanks for your response. - I'm running on Digital Ocean, 2 core 2 gig version. - Around 1500 mb. - What kind of swap do you mean? On an OS level? Thanks for the help! Erik On Friday, April 8, 2016 at 5:39:06 PM UTC+10, l.garulli wrote: > > Hi Erik, > > If OrientDB dies with no log,

Re: [orientdb] Re: Today, our OrientDB crashed without any errors.

Hi Erik, If system error happens (that is the only reason which we can think why it was shutted down without any exceptions) your OS log should contain information about that error. Which OS do you use ? On Fri, Apr 8, 2016 at 3:48 PM Erik Pragt wrote: > Hi Luca, > > I'm

Cool, I'll pass this on to a couple of PHP devs I know, who are also well versed in Graph databases (one even knows ODB well). Maybe they might be interested. I wish I were a better PHP programmer. I'd apply for the job myself. :-) Scott -- --- You received this message because you are

[orientdb] Re: Is OrientDB a good choice for a financial system?

It depends of the latency you are looking for. If you are ok with a relational database, probably OrientDB is OK too. If you are looking for microsecond performance and high frecuency trading, then you put all in ram. No Odb, no SQL. Your question is too wide. Could you narrow it? Pablo On

Re: [orientdb] Re: Today, our OrientDB crashed without any errors.

Hi Erik, Could you inspect following files /var/log/syslog and /var/log/kern.log using grep for example grep -i orient /var/log/kern.log and send us results. On Sat, Apr 9, 2016 at 1:35 AM Erik Pragt wrote: > Thanks! I'm using Ubuntu, I think 14.x > > On 09 Apr 2016, at
