Managing connections

Applications rely on the Sybase XA environment for management of client/server connections. Connection management occurs transparently to the application. Consequently, Embedded SQL applications cannot invoke the following commands for XA-managed connections:

• connect

• disconnect

Client-Library applications cannot call these Client-Library commands using XA-managed connections:

• ct_close

• ct_con_alloc

• ct_con_drop

• ct_con_props

• ct_config with the parameters:

  • CS_ENDPOINT

  • CS_EXPOSE_FMTS

  • CS_HIDDENKEYS

  • CS_MAX_CONNECT

  • CS_NETIO

  • CS_TRANSACTION_NAME

• ct_connect

• ct_exit

• ct_getloginfo

• ct_init

• ct_options with the parameters:

  • CS_OPT_CHAINXACTS

  • CS_OPT_FORCEPLAN

  • CS_OPT_FORMATONLY

  • CS_OPT_NOEXEC

  • CS_OPT_PARSEONLY

  • CS_OPT_STATS_IO

• ct_remote_pwd

• ct_setloginfo

• CS_OPT_STATS_TIME

In addition, Client-Library applications cannot call these CS-Library commands:

• cs_ctx_drop (with global context handle)

• cs_objects (CS_CLEAR, CS_SET)
