It's required to understand the different types of patches available. This can be (according to the documentation & my interpretation). Especially the differences between SYSTEM PATCH (in our case only Bundle Patches), COMPOSITE and SINGLETON patches, and BUGs - of course.
A way to handle all the information is to use the details provided by opatch and the patches, store them in some tables and afterwards query them.
For ORACLE_HOME related information, all the information required can be generated by a simple opatch command:
${ORACLE_HOME}/OPatch/opatch lsinventory -bugs_fixed -xml ${bugs_fixed_file}
This then needs to be uploaded into a table. For this purpose we use a SQLcl inspired by Kris Rices SQLcl examples.
${SQLCL} "${conn_string}" << EOF
script
var fileName="${bugs_fixed_file}";
var theBlob = conn.createBlob();
var outBlob = theBlob.setBinaryStream(1);
var path = java.nio.file.FileSystems.getDefault().getPath(fileName);
theBlob.setBytes(1, java.nio.file.Files.readAllBytes(path));
// ctx.write("length: " + theBlob.length());
var HashMap = Java.type("java.util.HashMap");
bind_map = new HashMap();
bind_map.put("theblob", theBlob);
bind_map.put("name", "${name}");
bind_map.put("version", "${version}");
try {
var retval = util.execute("insert into oh_registry (name, version, bugs_fixed) values (:name, :version, blob2clob(:theblob))", bind_map);
// ctx.write(retval + "\n");
}
catch (e) {
ctx.write("\n\n ERROR:" + e + "\n\n");
}
sqlcl.setStmt("select name, version, dbms_lob.getlength(bugs_fixed) from oh_registry where name='${name}'");
sqlcl.run();
/
commit;
exit
EOF
(blob2clob is just a wrapper for DBMS_LOB.CONVERTTOCLOB)With this information from several ORACLE_HOMEs, fancy stuff is possible with simple xml queries:
Which patches are different between 2 ORACLE_HOMEs?
select

, sub2.patchid as OH2
, NVL2(sub1.patchid
, NVL(sub1.patchdescription ,

So a lot of useful queries can be done when information regarding ORACLE_HOMEs is stored in a RDBMS.
Similar things can be done for patches as well. patches contain a lot of useful information. Those are stored in inventory.xml, actions.xml and if they exist in bundle.xml, and any README* files. If these files are loaded into tables similar to the method shown above, they can be used to generate even more insight. Some care must be taken as SYSTEM and COMPOSITE patches contain other patches which must be processed as well (together with their dependencies). We normalized the xml files to several tables during the load for easier/faster queries.
It's possible to search for all patches which will fix a given bug:

Using the available information about ORACLE_HOMEs and Patches together it's even possible to check if a patch can be applied to an ORACLE_HOME, or where they conflict.
