dsmoljanovic's questions

Title says it all. I want to have 2 versions of java on the same machine. For example 14.0.1.7 and 14.0.2.12 (which are both in EPEL7 repo).

If i install them one by one via yum, yum will remove first version and keep just the last. If I install them via rpm dependencies are resolved but not installed automatically. If i install first with yum and second with rpm then it works and it keeps both versions but rpm won't install any additional dependencies if the pop out at some point and it would be cool to be able to do it via only one tool.

All mentioned java are OpenJDK; EPEL7 has these rolling packages (for example: java-14-openjdk-14.0.1.7-2.rolling.el7.x86_64, java-14-openjdk-14.0.2.12-1.rolling.el7.x86_64).

Any ideas?

Now this is a very unspecific question. I'm trying to figure out what this message would mean.

Here is the story behind it: I'm installing Oracle enterprise manager cloud control (12c r3) on Solaris 10 (5/09). Installer opens up, i enter all needed information and at the last step click Install. It immediately crashes with only "ERROR: Not enough space" written in log and console and nothing else.

Now, this could be java error or Solaris error? I'm thinking it's happening either when it starts to copy files or when it tries to launch a process that would do that.

What space is it referring to? disk (have ehough), swap (also), memory (yep)...

Any ideas are helpful.

Edit: i found this exception in the oraInventory logs:

I'm using java on OEL 5.8 and it crashes in some applications with "Illegal memory access. [54] error". It occurs with 3 different java installations. 2 of them are Jrockit versions (R28.2.5-20-152429-1.6.0_37 and R28.2.2-7-148152-1.6.0_29), third one is Sun so i'm guessing it's not java problem, but a Linux one. Everything worked fine until few days ago when it started crashing. It doesn't crash on every java application, just few of them that are completely unrelated (both of them however have GUI).

Here is the relevant part of the dump. If needed i can upload everything.

Thank you for your help in advance.

I'm looking for explanation of services installed with debian so i would know which ones i can shut down and which ones are critical. I had no luck in searching the net.
