Considering Code Page Support
Siebel CRM 8.x supports ASCII-, EBCDIC-, and Unicode-based coded character set IDs (CCSIDs) on DB2 for z/OS. Development databases can use EBCDIC code pages. Databases with EBCDIC code pages support the following procedures in a development environment upgrade:
Merging prior configuration changes into a new custom configuration repository
Generating the Siebel Runtime Repository data by executing the Full Publish command in Siebel Tools
Some limitations on databases with EBCDIC code pages include the following:
Siebel Web Client migration is not supported
Siebel Dun & Bradstreet server components are not supported
Before you conduct an upgrade, carefully read Siebel CRM Update Guide and Release Notes on My Oracle Support for information about known restrictions. For guidelines about choosing the code page for your subsystem, see Implementing Siebel Business Applications on DB2 for z/OS. In addition, make sure you follow the rules specified by IBM for character conversion as described in the IBM DB2 installation documentation.
