How to Solve Key Mapping Issues in Oracle Reports 11g with cgicmd.dat

Oracle Reports 11g is a powerful tool for creating and delivering enterprise reports. It allows you to design, format, and distribute reports in various formats, such as PDF, HTML, XML, and Excel. However, sometimes you may encounter key mapping issues when running reports on Oracle WebLogic Server. These issues can cause errors or unexpected behavior in your reports, such as missing parameters, incorrect values, or wrong formatting.

One of the possible causes of key mapping issues is the cgicmd.dat file. This file is used to define custom commands and parameters for Oracle Reports Services. It is located in the $ORACLE_HOME/reports/conf directory on the server. The cgicmd.dat file contains entries that map a key to a command or a parameter. For example:

key1: report=test.rdf destype=cache desformat=pdf

key2: paramform=yes

You can use these keys in your report URL to invoke the corresponding commands or parameters. For example:

server:port/reports/rwservlet?key1

server:port/reports/rwservlet?key2&report=test.rdf

However, if the cgicmd.dat file is not configured properly, it can cause key mapping issues. Some of the common problems are:

• The cgicmd.dat file is missing or corrupted.

• The cgicmd.dat file has incorrect syntax or format.

• The cgicmd.dat file has duplicate or conflicting entries.

• The cgicmd.dat file has insufficient permissions or ownership.

• The cgicmd.dat file is not synchronized across multiple servers in a cluster.

To solve these problems, you need to check and fix the cgicmd.dat file according to the following steps:

• Locate the cgicmd.dat file on the server and make a backup copy of it.

• Open the cgicmd.dat file with a text editor and verify that it has the correct syntax and format. Each entry should be on a separate line and have a colon (:) between the key and the value. The value can be a single command or parameter, or a combination of them separated by spaces. For example:

key1: report=test.rdf destype=cache desformat=pdf

key2: paramform=yes report=test.rdf

• Check that there are no duplicate or conflicting entries in the cgicmd.dat file. Each key should be unique and map to a valid command or parameter. If there are multiple entries with the same key, only the last one will be used. If there are commands or parameters that conflict with each other, such as destype and desname, they may cause errors or unexpected behavior in your reports.

• Save and close the cgicmd.dat file.

• Change the permissions and ownership of the cgicmd.dat file to make sure that it is readable and writable by the Oracle Reports Services user. For example, on Linux, you can use the following commands:

chmod 644 cgicmd.dat

chown oracle:oinstall cgicmd.dat

• If you have multiple servers in a cluster, you need to synchronize the cgicmd.dat file across all of them. You can use tools like rsync or scp to copy the file from one server to another. Alternatively, you can use a shared file system or a database repository to store the cgicmd.dat file centrally and access it from all servers.

• Restart the Oracle Reports Services on the server or cluster to apply the changes.

• Test your reports again and see if the key mapping issues are resolved.

If you still have problems with key mapping issues in Oracle Reports 11g with cgicmd.dat, you can contact Oracle Support for further assistance.
