ORABPEL-01010 and "Could not generate named BPEL process file" when deploying composite using Ant

Problem:

When using Ant to deploy a SOA Suite 11g composite project, we received the following error below:

[deployComposite] setting user/password..., user=weblogic
[deployComposite] Processing sar=/home/oracle/scripts/deploy/svn/AhmedHelloWorld2/deploy/sca_AhmedHelloWorld2_rev1.0.jar

[deployComposite] .

Investigation:

Based on another forum posting, it was suggested to check and increase the number of open files.

oracle@oradev> ulimit -n
1024

In my case, it was set a tad low, so I increased it by running "ulimit -n 2048", but that did not resolve my issue.

Solution:

1. Check your disk space. In our case, our disk was 100% full.

2. Make more space, bounce the "soa_server1", and try again.

Applicable Versions:

• Oracle SOA Suite 11g (11.1.1.x)
• Red Hat Linux 5.5
