Creating file /oracle/sapinst_instdir/SOLMAN71SR1/SYSTEM/ORA/CENT RAL/AS/__instana_tmp.xml.
Sol-: You have to set the recommended OS kernel parameter (check your OS procedure) also set java environment parameters and test with java -version command if java is working under the user used to install oracle...basic prerequisite for OS administration part.
If you done these steps-:
temporarily shifted sapinst_dir under the oracle as default directory tmp got full. I ran pre-requisite checker and got two error as follow but I assumed its not relevant to this particular issue.
1. Environment variable (CPIC_MAX_CONV) =condition not met <
2. JAVA_HOME = Could not check <
You have need to remember this step when using java that what version and use parameter accordingly
you use the right java, in this case is JDK 1.4.2 downloaded from IBM, as far as I know. Also need to read the OS related notes as asep818 said in order to set the correct kernel parameters.
